My Dell Dimension 4550 won't power up. New P/S, power cord, etc. doesn't help.?

Q: My Dell Dimension 4550 won't power up. New P/S, power cord, etc. doesn't help.?

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?

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.)

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 !

I have a Dell all in one that is about 4 years old.  The other day I started it up and used it for a little bit.  I left to go eat and when I returned the computer was off.  I tried to push the power supply, check the power strip and made sure everything was plugged in correctly.  No change.  I did notice that the blue light ring around the power cord was off, so I unplugged it from the computer and the power strip.  Plugged it back into the power strip and the light came on.  Fantastic, until I plugged it back into the computer where it went out.  I tried other power cords (same size etc) and they would also have the light go off when plugged into the computer.  What can I do to get this fixed?

Hello all. First timer here.  I've had my HP Envy for only a year and it won't turn on.  Nothing out of the ordinary happened to it, but when I plugged in the power source and push the power button, the light next to the power input hole flashes 3 times.  I tried letting it sit overnight to see if it was just drained, but still no change.  I took battery out, plugged power cord into laptop and still nothing.  We use wifi as our internet connection and didn't receive and error messages or warnings before this happened. I'm not sure if it's just the power cord itself or something with the laptop. Thanks for any and all help!!! Joe

I have had my Dell laptop for almost two years now I battery Power cord Dell charging not - 1545 Inspiron replaced the battery before the warranty expired year The battery was working fine but I was starting to have to jerry-rig the angle of the power cord in the socket to charge the battery I purchased a knock-off AC adapter replacement Dell Inspiron 1545 - Power cord not charging battery I started getting error messages almost immediately when booting up that cord might not be compatible with the laptop As it was working I didn t worry about it The power light start flashing in a particular pattern then which it has been doing for months three fast orange flashes and one long white flash Historically a white light has meant quot charged quot and an orange light has meant low power The AC adapter became increasingly less efficient in charging the battery until it ceased to charge it at all I purchased the Dell AC adapter recommended for the newest version of my laptop model There was no noticeable change I understand from Dell that the problem may have been that I purchased a W adapter compatible with newer versions of this model but that I should have purchased a W adapter as my laptop is older I returned that adapter to Dell Dell Inspiron 1545 - Power cord not charging battery and then purchased a re-furbished Dell W AC adapter through Amazon Again no noticeable change The battery is taking absolutely no charge from these cords As I remove the power cord from the socket the computer instantly shuts down When I hover over the battery icon it says the battery is charged and that it is not charging When I right click and select the Battery Meter it says that my quot battery is performing normally quot but it lists the battery status as quot idle quot If I had to guess I would say this is a problem with the communication between the power cord and the battery I m concerned that I messed that up irrevocably with my continued use of the knock-off power cord I would appreciate any thoughts as to how I can improve the situation Thank you nbsp

#i.e; 2" hard drive or 3" hard drive

I have had the computer since May and all of a sudden the power cord will not plug into the computer, thus the laptop cannot charge.  I had no issues until this last weekend when I went to plug in the power cord, it just fell out.  I can't tell if somehow the receiving end inside of the computer got moved, or if the metal end of the power cord got pushed deeper into the hard rubber part of the cord.  It appears the cord cannot reach to connect.

Sorry I don't know the proper terms, but basically the pin inside the jack where the power cord gets plugged into on my laptop was bent so that it's really hard for me to plug in my power cord and have it stay in place. My warranty with best buy has expired, so I need to figure out how to solve this problem on my own. I can't just leave it like this because the cord comes out really easily and I can't continue to work with such a tenuous setup. Anyway, is this just a matter of replacing the entire unit inside my laptop? I know you probably need more information, but I'm not sure what to provide, so please ask any questions. The laptop is a Toshia M-45, about 3-4 years old. Thanks in advance

I saw a few threads about this stuff and saying it could be the power supply. It could be that but I wanted to make a 100% sure before I bought one. Here is the story, my girlfriend was taking apart the computer to clean it, it had worked before she just unplugged it any everything. She ended up cleaning up the computer from the inside and outside, but when she put it back together it won't turn on. When I plug the power cable to the power supply a little green light will light up on the mobo. But thats about it, I've tried a different socket and different wire with no changes. The light by the power button doesn't light up at all. Wondering if you guys think something could have messed up. I tried to check the connections and everything seems to be please!!

A:Upgrading a Dell Dimension 4550, need help


as a newbie you cant post links, as for Dell PC's why bother upgrading it, just sell it and buy a new unit, easier in the long run and cheaper, from what i remember Dell use specific PSU's in some of their machines so if you wanted to swap it out it would have to be a Dell PSU.

You can pick up a good spec PC for a few quid nowadays as they are getting cheaper all the time.

I know I have to take this computer with old OS out of service, but I wanted to know if this is a good candidate for ubuntu or a NAS server or media server. It runs well and has maximum RAM. It does have SATA.
Are people using this as a movie server in their homes? Can this be a file repository and then automatically sync with the cloud to backup files? I have a router that would allow me to access remotely, but thought if its mirrored in the cloud I could access files from my onedrive. I am also considering moving to google doc, or amazon or some other cloud server for my files, but I thought if I kept syncronized files on my home network it would speed things up and reduce bandwidth.
Thanks for yout help in advance.

It boots to safe mode fine. I even tried the memtest on bootup and it is only seeing 32mb of ram! I have removed the module and reseated and cleaned the contacts. No good.

A:Dell Dimension 4300 won't power up

In many cases, that's exactly the way that PSUs die. You turn the machine off, and it won't power back up.

The 20 pin connector shouldn't be a problem. Modern boards use a 24 pin main connector, but four of the pins usually break away, for this very reason, to maintain compatibility with older motherboards. The 4 pin you're referring to is CPU power, and it's also part of the ATX spec, so this would be present on a new PSU also.

That said, the PSU cutout in the Dell case is non-standard. Here's a random case I've linked; Please look at the PSU opening, you'll see that it's very different from the one in your Dell case.

The Intel 845 chipset is powered according o the the ATX spec, it's no different than newer boards.

Again, with that said, you really need another PSU present to see if the bolt pattern in your case matches up with a new ATX PSU. The Dell case is fairly large, and the mounting holes could possibly be re-drilled if they're off a bit.

Disclaimer; This paragraph is probably paranoid, or possibly histrionic:

The only "rub", is that the rear of the Dell case is partially closed, and if it fouls anything on a new PSU, you might have to get out the jig saw and open it up to squarish. That would involve taking all the insides out of the machine.

This might be more of a project than it otherwise would be, but as an educated guess it's probably doable.

This is a small to normal size replacement PSU; Full dimensions are under the, "details" tab.

Check it against yours.

My friend's dell dimension won't turn on. Pushing the power button does nothing. The computer was working fine recently then there was a power outage around the time. It doesn't seem like the PSU because I had it plugged in with the case open and there was a glowing green light on the motherboard which disappeared upon unplugging the computer.

Now here is exactly what happens when pushing the power button. No fans and/or indicator of being on. Nothing, no harddrive etc.
It really makes me think it is the switch.

How would I go about fixin this.
Bear with me and do try to be quick as the hurricane tomorrow may not allow me to get back on for a week.

On the power adapter for my new T460 the power cord only goes into the AC brick about 3/8" before it bottoms out.  Another 3/8" of the "skinny" part of the power cord plug is still outside the power brick. As a result, the power cord falls out of the brick at the slightest tug, pull or twist. I'm seriously afraid that one day I'll find I've lost the power cord half of the power supply. Why was the recessed part of the power brick made so shallow?  If the full 3/4" of the power adapter plug was allowed to be inserted into the power brick this problem would not happen. Anyone have a solution, other than buying a 3rd party power supply?

Emachine with XP Home - was running fine, but in the middle of copying a file got an error "Windows has encountered an error and will shut down."

The machine then refused to boot.

When I plug in the power cable, the PS boots without use of the power switch. No POST, no display, no error beeps. Power seems to be getting to the mobo and hard drive (LED activity), but nothing more.

What on earth could cause this? Where should I start troubleshooting?

Hi, I am trying to reformat a Dell Dimension on Windows XP Home, and have never had a problem like this, don't know what I am missing, the machine was purchased with XP home on it, and there is a reinstall disk. When you do the reformatt when it comes back up and runs through the process it does not ask for the product key? It reformats and when machine is supposedly all set up and ready to go half the information such as ethernet card, audio drivers etc is not there. If you are doing a complete reinstall should it not ask for the product key??? This really has me puzzled, I have reformatted 3 times, and am not coming up with the proper setup. I am going to work now and will not be back until this evening, but anyones input into this would be greatly appreciated.

I have the reinstallation CD, and have tried every webpage solution I can find. Still no bueno...

CD in drive

Computer will not boot from CD

Changed boot sequence in BIOs
Still no luck

CD will load/open find if chosen from MY COMPUTER option, but it will not boot or be recognized upon a reboot

Any ideas or tips?

This PC appears to have some issues too, so just wanna do a clean wipe and restore....any tips or walk-throughs would be appreciated. Tried for a whole day and still not NOTHING.

(Here's the last website solution I tried:

A:Wiping a Dell Dimension 4550 Clean


Does the drive read the OS disc in the current windows.

Do not forget to either have the Dell Drivers disc handy or download the drivers from dell to a flash drive.

If you are using the Original Dell OS disc it is bootable.

If the drive is working the pressing F12 when the Dell logo appears should get you to the Boot Device Menu. At that point it couldn't hurt to run the drive diagnostics Since you mention issues with windows. (Boot Diagnostic Partition) or you can boot the Dell drivers disc for the Dell Diagnostics.

if the disc is bootable and the drive is operating properly then you should be able to boot from it in the boot device menu.

You could test the disc in another computer too.

I am familiar with the Dell Dimension 2350 through the Dimension 4600 and if the disc and the drive are good it works.

A:No sound on my lovely Dell Dimension 4550.

Have you check the device manager on your computer, check if the sound card there are installed. You may see yellow exclamation mark on them.
Try updating the drivers from there ,intead of installing it using the setup utility of the soundmax.
BTW is this a built-in sound card?

Due to my kids constantly plugging things in and out of my USB ports 2 are now broken. I wanted to remove the motherboard so that I can replace the ports.

Look for a green tab to slide it out then once out one would remove all the screws & then give it a lil push to the left ,kinda like you would on a side cover of a tower.
Good luck I hope the link is of some help!

Look on the motherboard at the Northbridge heatsink as shown in the attached pic. There will either be one or two wires than run across the heatsink that connect to "loops" or "eyelets" on the motherboard (the red arrows point to the "loops" or "eyelets"). See if one of the "loops" or "eyelets" has pulled loose from the board.

I've got a Dell Dimension 4550 desktop that I've had for 7 years. It has worked fine but lately, I've been having problems related to the monitor and I hope someone can offer some advice (besides buying a new system).

For some reason, my monitor goes into "sleep" mode shortly after booting up my system. The only way to avoid this problem is to go into safe mode but I can't access the internet in safe mode. Any ideas on how to resolve this problem? I've already tried restoring my system (several times) to a previous date (going back several months) but to no avail.

Hi all,

I have a Dell Dimension 3000 (about 5 months old) running at circa 3.2 GHz, 160GB drive and 1G RAM. Video card is a Radeon 256MB. PC was running fine. Burned a CD last night. No issues. Tried to boot up PC today and flashing amber light. Checked Dell site. Flashing amber indicates possible internal power problem. Opened casing and checked all power connections. All in place as required. Definitely power to the mother board as the green onboard LED is lit when power supply is plugged in. PC still indicating power problems (amber light still flashing). Any ideas on what to do? Could the hard drive be fried?

Hi, i have a dell dimension 8400. My house was recently hit by lightning and caused my power supply to go bad. I am looking to replace it with an upgrade to the stock so that when I build my next computer i can use it. The stock isn't a standard power supply so I'm wondering how i we'll be able to buy one that will work for the Dimension and my future desktop. Im talking about how on the dimension thier is no place for a power switch like most.
Any ideas?

A:Dell Dimension 8400 power supply help

Some dell pw supplies and not standard atx that is the wiring is not standard. You need first to check with dell or the dell forum to see if your system uses a standard atx type pw supply OR a dell proprietary pw supply. If it is the latter, then you cannot install a standard atx pw supply.

Comes with a 350 Watt power supply.

Can this power supply handle a 6800GT or 7800GTX. I would think so becuase the system can come with an ATI X800XT if you choose it from Dell.

I just want to make sure before I purchase a higher level video card.

A:Dell Dimension 8400 Power Supply

DEll usually uses PSU's built by fortran so they are normally good power supplies. I believe that the 350 Watt PSU fals within the recommended guidelines for the 7800GT. if it doesnt you will have to get a new PSU, and since dell uses proprietary connections for PSU\Mobo you either have to get one from Dell or go to PC Power&cooling.

Recently on my 2003 Dell Dimension 4600, I have been experiencing random shutdowns, where it will just turn off, and when I would try to turn it on again, it will just power the USB Ports for some reason, instead wanting to boot. This has happened a few times, and if it just turns off I will have to wait some time for it to boot properly, but it will just power my keyboard, my mouse, and turn on my Seagate Free Agent, which I have in as a standby drive.

I have been repeatedly changing the power connections to the hard drive. I have a Thermaltake TR2 430w PSU, which I installed in January 2008.

So is this a motherboard problem or a PSU problem?

Computer will not power up. Power light on the power on button is blinking amber. When I first plug in power cord, standby power light (AUX_PWR) comes on. Tried reseating main power connector, RAM, all PC cards. When I first press the power on button I do not get even a slight indication that the power supply kicked on then off. Need possibliities or solution!

A:Computer will not power up - Dell Dimension 8400

My first guess would be the pw supply however it cannot hurt to do some troubleshooting.
1 Open the case and pull the pw connectors from ALL drives; both hard disk and optical type drives.
2 Disconnect any usb type device; ie hub, scanner, printer, etc.
3 Pull out any add-in cards except the video card
4 Now attempt a pw ON. If you get a display, great. If not shutdown the system
5 Locate the pw switch leads on the motherboard. Remove the lead. Use a small screwdriver or other metal part to jump across the pins on the motherboard. If it still does not pw ON and post, clear cmos and repeat.

If still no post in the above config, you need to start swapping parts with known good units. Start with the pw supply since that is much easier to change out than the mb.

I'm new to the forum, so I'm not sure if this is the correct location to ask this question. Please redirect me if not.

A guy at my workplace has a Dell Dimension 2400, maybe about 5 yrs old, that won't start up, just goes into power save mode. No pressing of keys or moving of mouse does anything. The error lights on the back are all off except D which is green. I can't find that light code in the Dell documentation. Also, the DVD drive has a green light, but won't open, so he thought that could be causing issues.

Any help would be greatly appreciated. Thank you.

I get a flickering amber light when I try to switch on. Nothing else happens (no screen, no boot up). I've tried unplugging all cables. The light will remain on for about 20-30 seconds even after disconnecting all cables (including power)

Inside the box I have tried unplugging/replugging the memory then the hard drive. This doesn't make any difference.

There is a small orange light on the motherboard just beside the motherboard battery. This remains constant orange whilst the power button flickers orange.

A:Dell Dimension 8100 power supply...

I am afraid some Dell power supplies have an extra connection to the motherboard and to use a non Dell item could lead to you frying your board.
The only way round it is to change both PSU and board, which is an expensive option.

A:Dell dimension 8200 power supply

Dell started using a properietary powersupply for their systems a few years ago. Even though a standard ATX powersupply will fit, it will destroy the motherboard. The best bet is to find a compatible powersupply but not necessarily from Dell. Dell spares are pricey. Try they may have one.

must be either the switch,the control board where the switch is plugging into...or the cable running to the main board...
or the main board itself.

when i work on a standard pc i use a screwdriver to touch the pins and power up a pc without a switch.
how can i do this on a dell desktop.

If you pull the power cord out while it is running, does it immediately die?  Are you sure the battery is good?  Is it a Lenovo or aftermarket battery?  I have seen aftermarket batteries act like they are good and charge, but really don't work.  As far as the fingerprint reader, go into the BIOS.  Under security/fingerprint, erase fingerprint data.

Well, I don't think it's a power problem, and here's how I plan to make sure:

Remove a device. Seriously, just pull something out of the case. I'd remove the video card, specifically, but that's assuming you have onboard video (sorta important to have a display).

If it boots, then it's a power problem. If it doesn't boot, it's something else. What else could it be? Well, most likely, it's a bad soundcard, but we'll blow up that bridge when we come to it.

Dell Parts claim they only offer my existing 250w power supply. They mention there are other 3rd party vendors who manufacture higher wattage compatible power supplies for my dimension 8200. My only problem is I can't seem to find any??

Can anyone be of any help here...?

A:300w + Power Supply needed for my Dell Dimension 8200...

Is your power supply one of the older ones that has the proprietary ATX connector? if so the only place I know that sells them is PC Power and Cooling.

Before I start I would like to say thanks to all that reply. I have a dell dimension 4700, first mistake from what I understand,with windows XP. I do not know if there is a hardware problem or an OP system problem. The computer stays in a power save mode and takes forever(days) to wake it up. The button on the front of the computer and on the monitor are always amber. Tried pwering down and back up again. The dell screen pops up for a second and then all goes black. If I hit any button on the screen it reads in power save mode hit any key or move mouse. Hate to say I called dell tech support and no luck. Rather buy another computer than spend my money with them!

This is Richard from the Dell Online Community Outreach group. It is possible that the system is locked in a loop. Try removing the power from the computer. When that is done, press and hold the power button for 25 seconds. Reapply the power and try to power on the computer normally.

Report back if there is any change in the boot behavior.

Hello, I need some assistance in diagnosing my brothers computerproblem. It's a Dell Dimension Pentium 4, running Windows XP. You power up the computer and the monitor flashes something like, Power save on please press any key. After this appears on the screen it disappears and the light near the power button goes from green to amber. We have rebooted the computer and unplugged all the cables. At first we thought it was the monitor but when trying his other Dell monitor on the same CPU unit it gave us the same power save message. So, I'm assuming its the actual CPU with the problem and not the monitor. Any suggestions on what we can do to fix this? Is this something that a computer store/electronics store is going to be able to fix without compromising any information/files that are currently on the computer?

Any assistance is appreciated.

Dell Dimension 2400 running XP...

I see a green light on the mobo when the machine is plugged in. When PC is turned on, I get no beeps, and the diagnostic lights remain dark. I get no beeps at all, the CPU fan does run, the power light on the front is green, the hard drive activity light is amber, The monitor displays a message about being in the power save mode, and to press any key or move the mouse. Of course, nothing happens when I do that. I have hooked it up to another monitor, which acts like it has not been connected to a PC (Check Video Cable or Input Select).

Did some searching on here and tried a couple of things. Turned computer on earlier and just got a black screen and two green lights on front. Turned off power from back(because power button on front didn't work), powered back on and an amber light came on and green light on the right. I can hear the fan running and I can open doors on my disc drives so i'm thinking it's not the PSU, plus I had replaced that from the original one when it failed a couple years ago. Another person suggested a motherboard test so I removed all the cards and disconnected all the drives like they said, powered back up and the solid amber light is now solid green. What can I try next?

I solved this problem myself after spending days searching on the web but since the solution seemed completely unintuitive I thought I d post it for any other frustrated user The problem Last year I installed a PCI card in my Dell Dimension to allow me to swap an old IDE drive for a new Seagate Barracuda SATA hard drive The drive worked fine for a while but then it periodically failed to be picked up on boot - the Silicon Image A controller would fail to find the hard drive and then the grub loader would fail I figured out that if I physically switched the connection to the other SATA port on the PCI card the drive would be recognised on the next boot most of the time This was a very annoying solution Recently the drive started disappearing while I was using Windows XP which was particularly worrying so I set aside some time to finally fix the problem My setup The SATA drive is set to SATA Besides the SATA drive I have an IDE drive set to master on the master cable which is my main boot drive I have an Ubuntu installation on the SATA on 4550 Dimension PCI-connected drive SATA Dell arbitrarily disappears drive The system dual-boots using grub I ve disconnected one of my CD drives and PCI-connected SATA drive disappears arbitrarily on Dell Dimension 4550 my floppy drive just in case to avoid power problems Things which didn t work Changing PCI slots for the SATA adapter card Changing IDE drive to cable select PCI-connected SATA drive disappears arbitrarily on Dell Dimension 4550 Updating BIOS or chipset from Dell s website Crying like a little girl The solution I disabled the built-in ethernet adapter supplied by Dell both in Windows and in the BIOS disabling the adapter in the BIOS would have been enough Everything s worked fine for two weeks Don t ask me why this worked During my web crawl I came across a post where someone mentioned that the on-board ethernet in some Dells disrupts the power supply to the PCI bus In fact had previously had problems with a PCI TV-capture card Anyway whoever that poster was quot thanks quot because it fixed my problem The one thing I hadn t tried was to update the A controller BIOS in my PCI card but I wasn t sure where to get a suitable update There s a thread on Icrontic Forums seemingly devoted to A updates in case anyone needs one nbsp

Have you tried Dell?

If they dont have a win 7 driver an earlier one can be used if it is installed in compatibility mode.

A:Dell dimension 400S + radeon 9550? what about the power voltage reqs?

go to this web site to calculate your power requirements and check the side of your power supply to see it's wattage. if your computer needs more wattage than the power supply supports get a new one

I hear that Dell computers have the power supply ports wired differently,so a non-dell power supply could possibly fry the motherboard.Click to expand...

Lol, did you talk to dell tech support?
Hahaha they lie.

Yeah should be fine, but of course, its not a particularly good card. You should be ok with the source engine if you load up the proper configs.

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?

This is unusual we would suggest you to check with another system to see if the same happens.

Does anyone know what model or type of adaptor I can purchase for my Dell Inspiron 13-7368 laptop for the power inlet so that I connect onto my external portable power unit (The connection to the power unit is USB)?
I do not have knowledge of how those the Dell power inlet are being classified and I cannot locate the specification for it. The AC Adaptor that I have for the Dell laptop is model HA45NM140. The information maybe on the AC-Adaptor but I do not know what I am looking for in regarding the plug in type for the inlet of the laptop.

I have a Dell 8600 about two years old. When I plug in the AC adapter, it intermittently fades to the battery as though the plug was pulled out (its not) and of course the screen fades in an out when every time it swithces--it does it every 30 to 60 seconds or so. I switched to a different AC adapter (I have a Dell 600M with the same AC adapter)-same thing so I know it is something internally. Any ideas?

When I am trying to connect my All-in-XPS - DELL XPS18 1810, to the power source it's indicator LED light is just blinking. Battery is showing 2-4% and when the charge is drained it will shut down. In the BIOS it is saying battery is still good. Is it a problem with some IC component is burnt due to voltage issues or something like that? Power adapter is also seems to be fine. We tried it with a different adapter but the result is still the same.
