Dell will not start, power adapter okay

Q: Dell will not start, power adapter okay

I have a Dell Inspiron 9100. I have checked the adapter/charger and it is putting out he correct 19V.

However, the LED lights on the battery do not indicate anything. After charging for 10 hours, I push the power button and nothing screen activity, whirling, noise, etc.

I have tried starting with adapter connected and not connnected.

Could a battery be so dead that the computer will not turn on?

Or is it the MB or bios?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Try removing the battery and starting the laptop using only the AC adapter. If you still get nothing, the motherboard is most likely bad

So I Noticed my laptop has stopped charging,"AC Adapter Can Not Be Recognized" I have the Dell 130w power supply plugged in and it refuses to charge I have tried the dell fix it (take the adapter apart and back in) that has not worked, so i thought hey its the "Dell Power Management" that is stopping my laptop from charging.... WHY can I not disable it?? Dell own bad software is stopping my laptop from detecting its AC cable and the same software is "protecting my laptop" by stopping it from charging.How do I get a new AC cable or how do I disable the Software?

This morning I woke up to see blue flashes coming from my office at home Inspiron Adapter Power Dell 9300 My cat had eaten through the cord BETWEEN my LAPTOP Dell Inspiron 9300 Power Adapter and it s POWER BRICK Fortunately the cat had also pulled the cord free of the computer - and the power brick itself seems to be in good working order Unfortunately the cat was still alive and probably hadn t been taught much of a lesson I took one look at the cable and decided that the two areas where the cat had eaten through plastic just had to be cut from the cable luckily both bite-spots are close to each other and then the remaining good parts of the cable could be spliced together However I m now wondering if a trip to Radioshack is in order I would like a longer cable between power brick and computer anyway Since I am at work now and would like to swing by radioshack on my way home from work I cannot take another look at the damaged cable I ve checked online and can find no pinouts or schematics of the power supply So I guess my question is this If you were going to repair an Inspiron Power Supply cable and you wanted to do a really good job of it what supplies would you pick up from Radioshack while you re out shopping for a cat defibrillator Any idea what kind of replacement cable I should be picking up Also are there any protective cable sleeves I can buy to prevent this kinda thing happening again nbsp

I have a dell inspirion laptop 6400 running xp home.

i turned on my laptop today and i gt a message telling me that it can'r recognize my ac power adapter. says it will power the laptop but wont charge the battery. says i can reset the power adapter.

does anyone know how to reset it?

My laptop is 18 months old & has been powered up a total of less than 100 hours, mostly with the power adapter plugged in. It has been carefully handled.
Recently on startup I get the following message :
"The AC power adapter wattage & type cannot be determined. The battery may not charge. The system will adjust the performance to match power available. Please connect a Dell 65W-AC adapter or greater for best system performance. To resolve this issue try to reset the power adapter."
This message shows up every time on a re-boot. Have to hit F1 to continue. Power meter shows 100%.

Is this an indication that the Model HA65NS1-00 rev: A01 adapter supplied by Dell is about to fail? What might be generating the error message?

I have a Dell Latitude 800 laptop. I need to dock it (because of a broken power adapter connector) but when I boot up I just get the message "your computer is docked but power adapter type not recognized. Press F1 to shut down" There is no other option but to shut down.

I am using a genuine Dell power adapter (PA-10) will full wattage (90W). I also just purchased a new adapter because the old one might have been damaged. There is no change in the message and I cannot boot the computer or charge the battery. Any way to get around this message--again I am using all genuine Dell equipment but the computer is not recognizing this.

I have a Dell vostro 1400 laptop. I am running Windows Vista.

When I plug my power adapter into my computer, I get the error message:

The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation.

I am using the adapter that came with the laptop when I purchased it about 15 months ago. The laptop still runs off of the charger and so it functions when it is plugged in, but the battery itself is dead. My battery health is good and nothing is broken off of my charger. Please help me!

A:Dell Inspiron Power Adapter problem

It's almost certainly the battery. Depending how it was cared for, how much it charged/overcharged, and what type it is, it may not be at all unusual for it to quit after a year and a half. Do you know what type it is (Lithium, NiMH, NiCad, etc.)?

It can't be the adapter if it is powering the machine.

What percentage charge does it say the battery has?

I plugged in my dead(battery needing charged) laptop only to have the power adapter start making a high pitched whinny sound. The green light will not light up on the box. Any ideas what could be wrong with it? If there is no way to get it back in working order, does anyone know of a cheap and good place to find a new one? And how do I tell if its actually the one I need? My power adapter says its part of the PA 10 Family, It also states 100-240v-1.5a, Output is DC 19.5v 4.62a. Any help would be greatly appreciated as my son watches movies on my laptop and is very upset that I can't get it working. Thank you so much in advance.

Hi -- not sure if this is the right place for this so apologies if it s not I ve had my Dell Inspiron m for about Dell Inspiron with 600m adapter power Problem & a year and half Problem with Dell Inspiron 600m & power adapter and in the past couple months the power adapter seems to quot shut off quot The green indicator light goes out and my laptop begins to run on battery power If I unplug the power adapter and plug it back in it starts working fine again The frequency of this seems to vary and I can t identify any behaviors I m doing that are associated with this happening Sometimes if I leave my laptop unattended for a couple hours I ll find that the power adapter has shut off and the battery has drained to the point where the laptop has to go into hibernation mode What might be causing this Is it something wrong with the power adapter itself or something in the motherboard or laptop itself Any advice would be much appreciated nbsp

A:Problem with Dell Inspiron 600m & power adapter

The problem is most likely one of three things. However, I have to ask a two question first!

Do you mean the GREEN light on the AC Adapter or on your Laptop. I am assuming on the AC Adapter for this response.

Do you keep your laptop plugged into the same outlet all of the time? The reason I am asking this is that it could be a bad outlet or the outlet could be damaged and the power supply is simply losing connection at the outlet.

1. Possible outlet problem as in it has a worn plug in and the ac adapter loses contact. This can also happen on a power strip too!

2. Could very well be a failing ac adapter.

3. Could also be caused by the battery.

If #1 is a possibility, try a different wall socket.

If it does it in all sockets, you could remove the battery and plug the AC Adapter into the laptop. It should run without the battery too! This would rule out the battery as being a problem! If the AC Adapter fails without the battery, then it is the AC Adapter. If it works with the battery out, then it is most likely the battery!

Hope this helps!

I have a Dell E1405 Inspiron laptop with a 100% battery charge. The issue is that the computer will not function without the adapter plugged in, rendering the battery as dead-weight. In the boot menu, the battery is showing as "Idle: 100% charged". However, Battery health is telling me "This battery can no longer provide sufficient power to your system and needs to be replaced'. So, I'm wondering, is my battery bad or is my PC not synchronized with the battery?

Could be a faulty battery or more likely it might be the jack thats gone faulty its quite a well known fault if the computer is getting on a bit, the contacts inside the jack tend to stick ....

Hi RAYB871,
Please check if there is any damage on the machine. Check if all the ports on the machine are fine or misaligned. Sometimes if the pins in the USB ports are touching each other, they are known to cause many issues on the machine.
Three components cause this issue, in this order:
Adapter - you have already tested another adapter, so ruled out.
DC Port - the port that holds the adapter in, might be shorted - you would need this part -
Motherboard - I would primarily suspect this part, if the dc port does not fix the issue, then it is the motherboard that has failed and needs to be replaced.
If there is no warranty, then you could contact our team to get a quote for a paid service call -
Personally, I would suggest, you invest your money on a new machine than to repair this old machine. However, it is your discretion.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.

It was working fine till last night. this morning I connected it to charger (without starting it) (charging light was on on laptop) and went to sleep. When I woke up,the light was off and it refused to start. I have been trying since morning but no success. I have tried that static charge method too.
also as soon as I connect the AC adapter,a buzzing sound near the charging port on laptop can be heard. it was never there before. The sound stops as soon as I switch off the charger.

A:Dell XPS 12 - Won't start / power up after hard reset

OK - I've narrowed it down to the following:
When the laptop is "asleep" it eventually goes into power down mode. It appears that connecting a power adapter to the laptop at this point will cause it to go into a confused state where, when the power button is pushed,  the laptop fan comes on but no light on the power button or on the keyboard - the screen  stays blank.  The laptop fan runs (it's very quiet - you have to hold the laptop up to your ear to hear it.)
I don't know if the cause is a low battery or if the problem is simply with the state of the CPU at power down.  I just know that when it happens, it if I disconnect the power adapter and hold the power button until the laptop fan shuts off, the hard reset allows it to come back normally.  If you leave the power adapter attached, it will charge the battery but will not allow the laptop to start.
I've repeated this experiment several times with the same result every time. I'm guessing there's a bug in the BIOS that sets an error state that won't clear with the power adapter attached. Doing the hard reset without the adapter appears to clear the problem reliably.

A:Dell Optiplex 780 (DT) auto start for a few seconds when turn on power strips!

That's perfectly NORMAL!
When you turn on the power strip, the PC thinks it's recovering from a power failure. So it powers itself up to check to see how the BIOS power option is set for recovery from a power failure.
If BIOS is set to "Do nothing", PC turns itself off again.
If BIOS is set to "Restart after power failure", it automatically boots without you having to press the power button.
So if you're lazy, you can set BIOS to reboot automatically after power failures. And when you turn the power strip on, the PC boots and you won't have to press the power button.

My laptop will no longer turn on.  When the AC adapter is plugged in, the LED light is white indicating power is arriving at the laptop. However, nothing happens when I push the power button. Troubleshooting steps I have completed already include: Hard reset (several times including after each step below)Tried starting without the batteryRemoved all removable components and reseated themRemoved all removable components as well as bottom cover. Cleaned with compressed air. Put everything back.Nothing appears wrong and nothing happened between the last time it turned on and this time that I am aware of.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

I need a cross reference for these kinds of numbers.

Kensington referred me to their telephone tech support; but, there is a language or cultural barrier that prevents their understanding what I need.

Does anyone know of such a reference?

In reference to the following posting,
I am not the individual who initiated this query but I did have the same issue with my Dell Inspiron 5547, where it wouldn't turn on after a power button shut down.
I followed Hema's instructions by removing the battery and charger and then holding down the power button for a few seconds, and then putting back the parts. It seemed to have done the trick... At least for now. Is this just a temporary fix?
While doing a Google search for a solution I seem to have encountered a number of people who experienced the same issue. Can you also explain why this happens with this particular Dell laptop? Is it a model flaw?
Thank you

But my machine is not showing any such on screen messages while booting. It stay blank till it enters the desktop screen. What could be the exact cause and solution for this problem?

A Dell customer service advisor recently suggested I buy a new battery to fix a problem with my battery not being recognised at system startup nor charging when the adapter is plugged in Despite my AC adapter being the original adapter that shipped with my computer the new battery still fails to charge I receive a message informing me that the AC adapter type cannot be recognised quickset Furthermore in what can only be described as an outrageous step this message informs me that Dell will throttle my machine quot your computer will run more slowly quot and then adapter charges Original new, Dell (a no AC battery Dell) longer battery will not charge Clearly there is an error in the adapter hardware Original Dell AC adapter no longer charges (a new, Dell) battery most likely related to the well known one wire technique for battery verification nbsp meaning it cannot be recognised by the computer I was therefore incorrectly informed to buy a new battery that neither solves the problem nor is of any use as it cannot be charged Is this how Dell treats their customers I propose two solutions which Dell could offer me Send me a new working W adapter compatible with my XPS as a gesture of goodwill following the incorrect sale of a new battery at great expense which failed to solve the problem Provide a way to circumvent the faulty charger verification process This is crucial for two reasons Firstly the adapter is the original adapter that came with my computer so to verify its authenticity is not necessary Secondly Dell has zero right non whatsoever to force consumers to use certain products through an invasive procedure that slows down a computer for which I have already paid If Dell will not provide a work around to overcome the throttling of my computer then I will demand a refund on the original value of my computer as I am no longer receiving the power that I paid for I look forward to hearing from Dell regarding this matter and from other users in the community who might have suggestions as to how to proceed to overcome this problem or engage Dell in finding a solution for customers

I recently purchased the Dell USB-C to VGA/HDMI/USB/Ethernet Adapter (Dell 470-ABQN) to use as a dock with my XPS 15 9550. Unfortunately while using this adapter the fans run at a very high speed, approximately 80%, and are therefore loud and disturbing during meetings and desk work. I have it connected to only an HDMI monitor and a USB mouse receiver. The fans also run constantly when using the built-in USB and HDMI ports, but at a tolerable level. I will have to return this item without a fix, so could someone at Dell please advise if there is a solution or if this is a known issue that will be reviewed? I have updated both the Thunderbolt firmware and software and applied all Windows Updates. Thanks

recently bought a Dell Inspiron 14 5459 on June 12, 2016 and first thing I noticed is that to turn on the laptop I need to press and hold down the power button at least for 3 seconds in order for the laptop to boot up, this seems strange, I brought up this issue at the Dell Store where I bought the laptop and the sales people there told me that they noticed this in most Inspiron models.  Is this normal?

Hi recently my Dell 2330 wont boot up properly. I press the power button and the light comes on the button and i hear the fan. The screen is a brighter black then after a few seconds the screen seems to go off but still power and fan running. Ive spoken to Dell and done all what they asked. Then today out the blue it came on as normal. I went to run a diagnostics test from a link Dell sent me and it asked me to restart the computer. I did and then it  did what it did before and has not come back on since. They have said it could be the motherboard. Any other suggestions ? Thanks

The system's fan was very loud so I put in a new power supply and then everything booted up fine. Unfortunately, that didn't solve the problem. It was the Motherboard fan making all the noise.

So, I put the old power supply back in and now the system doesn't power up at all. I checked all connections & I replaced the power cord and tried a different electrical outlet.

I even put the new P/S back in and nothing changed. It still doesn't power up. It's dead!

Any suggestions?

Do you mean the CPU fan ?
If so then I wonder if the CPU has been cooked

I would start by dispersing all internal voltage.
Detach the power cord
Press the power button in for 20 seconds
Re=attach the power cord
Try again

If it didn't fix then remove all addons, usb devices really anything attached (except screen and keyboard and power cord)
And try again

If it didn't fix then, confirm all internal connections are secure (even detach the dvd drive{s}

If it didn't fix then try disconnecting all fans (what !) for about 10 secs (turning on) I once had a fan of all things, that stopped my computer from turning on (unbelievable, I know)

Lastly, check the CPU for heat damage !

A:Power Supply - "The AC power adapter type cannot be determined....."

You are correct, the failure is due toloss of the power supply ID signal. Sometimes this happens because of strain on the plug, which breaks the signal wire. Some even are so severe that the insulation breaks away from the plug; this is due to rough handling. The other cause is one or more of the power socket solder connections to the system board become broken. This also is related to severe handling. I have seen one case where all three power connections and three of four mechanical connections were disconnected. If the power supply is bad, a replacement will cure the problem. If not, then the socket is bad, and this will require a system board replacement. If you are experienced, you can try to resolder the connections. I am experienced and was not able to get my daughter's E6000 to work by resoldered. More recent Dells are using a replacable power connection board which is a much cheaper repair.

A:Power adapter

The system is designed to support both 45W and 65W adapters - see the specifications here -
When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Could you test with another power adapter if possible?
Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point.
Restart the system and press f12 key on startup - choose diagnostics. Let it run the diags and if you encounter any errors - make a note of the complete error and report the same to us.These are onboard diagnostics and they might possible pick some error if the hardware is not functional.

Hello aaronbaron,

Reseat the power adapter just means make sure the power adapter is plugged in good on the laptop and the wall outlet. I would try powering off the laptop, unplug the power cord, take the new battery out. Reinstall the new battery only and try to power on the computer. If that does not work plug in the power cord and power up with the new battery installed.

So I have an ASUS P4C800-E motherboard in a system that a built a few years back. It worked fine but the system has been sitting in my basement for a year or two unused.

I decided to take the components and drop them in a new case.

I have hooked everything back up properly (i think) but when I hit the power button, the cpu fan, power supply fan and case fans turn on for a brief second and then shut off. (the green standby light on the motherboard is on)

What do I do?

I think you can tell from my question I am exteremly amatuer at this. Simple explanations please...

A:Turn power on... fans start up then power shuts off in 1 second

With it shutting down after 1sec, I would check that the hsf is plugged in and working. If there is no fan input ie fan speed, most boards shutdown. In addition that the hsf is installed correctly. If it is loose, etc you will have problems. Most of the time when the hsf is loose, it shuts down in about 5~10sec not 1sec. I tend to think it is more of a shorting problem of the board to the case.

If that is not the case, I would attempt to pw ON the system outside of the case. There are complete instructions in a guide at the top of the forum. It is called troubleshooting guide for problem builds.

I have a compaq nx6325 lap top, which will not turn on at all. The power adapter

A:Power adapter center pin

Sounds like the Centre pin has broken away and lodged itself in the plug. I cannot tell you which is positive and which is negative with regards to the rings on the plug. Because different Manufacturers use different combinations and with that different Voltages too. Generally speaking the outside piece is the male end and the receiving plug is the female -go figure-
Hope this link works you can see what I am mentioning, obviously this is not your cable but for the example of male to female ends the description matches the pictures ( not the 'Y' cord on the link )

I was hoping someone could help me out finding a power adapter for an old set of Harman Kardon speakers I have. On the back of the speakers it says ac 15v 1.1A so I assume I need an adapter that matches those settings.

Can someone plz help me out finding one that will work and is as cheap as possible.

Thx a bunch.

I have an hp pavillion dv 6000 that I lost the power adapter to. My friend has an adapter for an hp pavillion dv9000 that he does not need anymore and he wants to sell it to me. I want to know if it will work with my computer. The adapter puts out 19volts 4.74 amps 90 wants max. The replacement adapters for my model (dv6000) list the power output as 18.5 volts 3.5 amps 65 watts.

Will an adapter that was higher voltage amps and wattage work for my laptop that requires less??? This is assuming that the connector is the same which I'm not sure of.

The power adapter on my HP Zbook 15u G3 is not recognized. I tried an alternate power adapter, but that is not recognized either. The charge on the battery is almost empty. I've been waiting on hold for 30 minutes with HP tech support. The notebook is only 4 months old.

Support was able to fix the issue. Holding down the power button & mute button for 30 seconds fixed the problem. Thank you

Recently I purchased a VX1945WM monitor and I was not given a power adapter to run the different integrated features that the monitor offers such as powered speakers and iPod dock among others. I tried contacting Viewsonic, but that was to no avail. If anyone knows the model number or distributor, please let me know.

Can anybody answer the following questions about a laptop power adapter?

Is there a maximum length for the dc cord? In other words why do they locate the adapter 1/2 way down the cord instead of closer to the outlet.

Is the small cylinder around the cord about 3" before it enters the laptop some sort of choke/filter?

There is no particular reason for this, either side of the power supply could be lengthened or shortened.

I have a w power adapter from an older notebook that will work with my nbsp HP DV - nr I transport my notebook between home and office I'd like to nbsp utilize the older power brick so that I won't need to transport a power brick back and forth The tips on both adapters of course are of a different diameter nbsp nbsp nbsp nbsp nbsp nbsp My multi-tester identifies that the tip is hot for both adapters The problem I have is that the older power brick has two wires nbsp core wire and shield - and nbsp the nbsp newer power adapter has three wires shield that is connected to the nbsp core of tip black that is connected to outer part of cylindrical shaft that Power adapter? Wiring for must be the ground and nbsp white connected to inner part of cylindrical shaft also negative nbsp So do nbsp the black and white wires on the newer adapter need to be soldered nbsp to the shield on the older one nbsp nbsp nbsp

A:Wiring for Power adapter?

Just a guess, since it is 90watt, they may have run the extra wire to carry the load, shield is always much larger than center tip wire. Did you measure voltage and ploarity of all three connections with the brick plugged in? Tip is always + and ouside is always - on a HP, not sure what the third is, see if there is any voltage on it, It could also be some sort of sensor wire for the charging system on the mobo. Better to buy another adapter than smoke the motherboard on the lappy taking a chance. If you want to chance it just connect the two wires that are on the center and outside. Leave the 3rd odd one unconnected. probably can be found used for cheap.

I have a 20 pin motherboard but the power supply I have available has a 24 pin connector. I've read that you can simply plug them together by offsetting the 24 pin one but so far I don't see that working at all (and 'never the twain shall meet', so to speak). I've found adapters but they all say something akin to

'allows you to connect your existing 20 pin power supply to your new 24-pin compatible motherboard'

You can use it the other way around, correct?



A:20 to 24 pin power supply adapter

Some mainboard connectors are 20+4 pins where the 4 pins unsnap from the 20 pins for use with boards with a 20 pin connector. If your power supply doesn't have that feature you would use an adapter such as this.

I have an Acer 3690 laptop. Recently the original power adapter went bad. I went to a local computer company and had them order me a new one. The day I got it home and plugged it in the adapter smoked and the plastic split showing bare wires. We returned the adapter and they exchanged it for another one. The day we took the new one home it did the same thing. Any ideas what could be the problem???

What is a good, affordable universal power adapter for a laptop. My dad's power adapter for his Dell Inspiron 1545 laptop went out and I need an affordable replacement as I can't pay for a direct replacement right now. The output for the dead power adapter is 19.5V and I believe it is a 65 watt power adapter.

Do check the Seller Rating. I also look for closest shipper (I want what I want when I want it). You should see all the details in the Ad for what you need, if details are not there, you can move on to the next, or contact the Seller. Either way, they have a very fast return policy if what you ordered does not suit your needs.

I have a Toshiba Satellite A215-S4807. I need a new power adapter. (there appears to be a loose connection in it somewhere. It only works when I king the wire a certain way.

This adapter from Targus says that it is compatible but it is only 70W where the original was 120W.

Would the differnce in wattage present a problem in trying to use this adapter?

Thanks very much for your help.

I had the power cord replaced last year. But now I find the power box cord is not working. My battery died completely and even with the power cord plugged in, my laptop will not work. The box, even after replacing the power cord, still got extremely hot. Now I can't use my laptop at all! What do I do andhow much is it going to cost? Why is this not on a recall?

The Yoga 3 Pro power adapter looks like a normal USB brick, and the cord looks like USB, except with a kink in the connector at the Yoga 3 Pro end. Can I charge my phone or tablet with it?

A:What's with the Yoga 3 Pro power adapter - it's a ...

Yes the Yoga 3 Pro power adapter is a USB charger too!

How does it work?

The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.

Can I charge the Yoga 3 Pro with any USB charger?

No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.

Can I charge a USB device with the Yoga 3 Pro AC adapter?

Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.

Where can I buy spare AC adapters and cords?

AC adapters with cords are sold in the accessories section of the Lenovo store.

Where do I find the part numbers for the AC adapter and cord?

Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.

What are the USB specs of the Yoga 3 charging port?

It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

This is a recent problem - a previous adapter broke and now subsequent adapters use 100% CPU and sloooow my laptop.

It's an hp 6720s 13 months old, XP Home, HP 65W power adapter.

Laptop running fine on battery only. Laptop runs fine when battery removed and power adapter is connected. Laptop does not run fine when battery and power adapter connected - 100% CPU.

Also, the charge indicator light no longer works and the power icon does not show that the battery is charging, although it is.

I've updated the BIOS, restored factory power settings and tested the power adapter during startup and have the same prob with the CPU usage.

What could cause the power adapter to use 100% CPU? Please let me know if you need more info, cheers.

Hi everyone.

I know that this is not really entirely related to a Windows 7 computer and especially to these forums, but I really need some advice on this and it would be great if anyone who has experience in voltage, amps and safety for laptop power adapters would be perfect.

My friend has just traveled down to my house for a week but has foolishly forgot his plug for the power socket on his power adapter. He uses this for his computer. Again unrelated becuase it is an Apple 45W MagSafe2 adapter.

So I was wondering if he could simply use a cord like this one below to plug into the adapter?
The black cord is 2.5A 250V~

The adapter is 100-240V~ 1A

These are both for input.

Any help would be greatly appreciated .

A:Power Adapter Problem

That white 'thing' appears to be for an Apple Macintosh MacBook/MacBook Pro [I have a MacBook Pro] and you might not be able use the black cord due to fit, the V-shaped notch in the black plug would have to let it be inserted. But it probably won't hurt to try as it's still a 110/120Volt source.

The MacBook power adapter also came with a piece that replaced that cord and has the prongs to plug directly into a wall socket/extension cord, maybe it's in his Notebook bag.
