What pins should I short to start power supply so I can test it?

Q: What pins should I short to start power supply so I can test it?

This is an attempt at understanding what makes a power supply wake up.

I believe that you have to short a couple pins in order to make this happen.
Anyone know what pins to short?
Or am I on the wrong track?
I have a Power Supply checker that causes the PS to come to life when it is plugged into the molex connector. However, i am curious if, in the absence of this tester, if I could check the PS with a multimeter.

The Dell desktop motherboard has a front panel connection with a total of pins and a separate power switch connection Anyone know if it s just a matter of finding the power pins Motherboard What To Pins A Test I Run 7010 2 Do Short It? Dell On to short and start this up or is there more to it I ve tried shorting every pin setup in the front panel and power switch no luck although I suppose it could mean a bad motherboard However without knowing what pins are for power how am I suppose to know for sure Also is it possible that more then pins have to be shorted or touching to start this bleeping dell motherboard I m guessing the power pins that I would have to short are in the power switch connections and therefore I don t have to do anything to the pins in the front panel connections I m hoping there are no other pins that need to be connected besides power pins to get this to start I m not concerned with What 2 Pins Do I Short On A Dell 7010 Motherboard To Test Run It? any other pins except maybe restart nbsp

I recently purchased an MSI kn7420 Motherboard and have most of it hooked up. But there are only three pins on the mb for the power supply fan plug. The p/s plug has four pin holes in it. The colors on the plug are yellow/black/black/red. I did notice that my previous motherboard only had three pins also so one of the holes wasn't used (the board only last several months though, could that be why?) is there anyway of changing the wires around on the plug so it would work well with the board or could I just plug it in as it is bypassing one of the wires (if so which one don't I use) I didn't want to just try that and see what happens just incase it was damaging.

Thanks for any response

I'm assembling a new system and having power issues. When connected and the switch on the power supply is on, all my components receive power before I press the power switch. Fans turn, DVD drive spins and opens, yet I am not able to power up my computer. I stripped everything down to just the motherboard, CPU and RAM and I still get nothing. No POST beep or anything signaling a startup taking place.

I am wondering if this could be caused by a faulty power supply (ie a short inside the power supply) or more likely by a short in the case somewhere. Any help in resolving this would be appreciated!

A:Power supply/case short issue?

reassemble the minimum system components outside of the PC case on a non-conductive surface (eg the box that came with your motherboard). this will show you if its shorting to the case or an isolated problem.

What brand and model is the PSU?
Reseat all the components (ram, video card, etc).. you might want to try reset the BIOS at this stage since you've got nothing else to do

It is normal for some PSUs to start up the fans and/or other devices for a few seconds after puting in power to it or after shutting down the PC, but irregular if it doesn't die down by itself after a few seconds to a minute or if you can't manualy trigger it (shorting the two pins instead of pressing the power button to turn on the PC)

My machine has started randomly mysteriously rebooting on it's own. I've run scans, etc. One time in the past, the problem ended up being the power supply.

Is there a way to test power supplies to see if they are failing? I'm looking in the Cyberguys catalog, but don't see anything for that - or maybe I'm overlooking it.


A:Is there a way to test power supply?

There are power supply testors you can buy. You can also use the BIOS to monitor teh voltages its outputting or use Windows based software like Speedfan:

These aren't 100% sure things as they might not necessarily tell you if the power supply is just a little bit flakey. If it can't supply the right amount of power under heavy load, if its overheating, or if its just a sh!tty unit that isn't worth the materials its made from that randomly malfunctions.

A:How To: Test Your Computers Power Supply (PSU)

Not bad but not conclusive, either. I have seen (and replaced) many a PSU that test okay under the very light load you suggest. But once they come under full load they fail (even though the PSU may appear to be still working). You need specialised equipment to properly test a PSU. The easiest way is to test the system with another PSU - if it works then the original is faulty.

I recently had to replace the power supply in my desktop PC. Can anyone recommend a free software program that will allow me to test my power supply and make sure that everything is running as it should?


A:Software to Test PC Power Supply

You can use a hardware monitor like HW Monitor to monitor it's voltages:
But there is no software that can test a PSU.

You can get a hardware tester too like this:

But really non of this will predict if the PSU will fail, if you have it overloaded, if its running at high temps, or if the PSU is a poor quality unit that can be prone to failure.

Best thing is to purchase a quality power supply and have the computer plugged into a Battery Backup/UPS that does AVR.

Suddenly my dell latitude d620 stopped working. Message when I boot the laptop is "Start DST Short Test - no hard drive detected - error 1000-0141".

I removed the hard drive (hitachigst travelstar) and placed another one from another laptop. The laptop worked well. I placed the 1st hard drive in the 2nd laptop. I got the same error as above.

So is something wrong with the hard drive???

When I shake it gently, I can hear a small part moving inside. This doesnt happen in the 2nd hard drive. So is something broken too?

I recently ran a scheduled diagnostic test of my PC with the manufacturer's diagnostic software. I received two error messages and the advice to promptly replace my hard drive. The first message was Failed (Error code: WHD20-1VR) and the second was Failed (Error code: WHD16-T57). The apply to Targeted Read test and Smart Short Self Test respectively.

So I ran Chkdsk for the C: drive and received no error messages.

Which is correct and what should I do about it? The error message won't go away on the software.

Thanks for helping.


A:Question: Failed Targeted Read Test and SMART Short Self Test

CHKDSK is a very basic check that mostly checks file system and can be set to scan for bad sectors. The manufacturer's diagnostics actually check the physical drive to make sure its operating within the designed parameters and is more thorough.

You should replace the drive.

The SMART Self-Test Unit means that the diagnostic utility failed to read some certain sectors on the drive and predicted an imminent HDD failure.
If with the test you did you are getting a SMART test or a smart short test failure then I believe you need to back up your data and be ready to replace the drive.

Sounds like a failing hard disk, but the overheating thing is worrisome.

The TOSHIBA MK6465GSX is a 2.5" form factor SATA drive, 9.5 mm thick. You should be able to replace it with any drive with the same dimensions. (You probably can use a thinner drive, but a spacer may be needed to mount it.) That includes SSDs that are intended as laptop HD replacements.

I see that there are a couple of YouTube videos showing how to replace the HD for your model laptop.

A:pc won't start - power supply failure?

Okay, this could be two things: the power-supply or the monitor, both of which you'll need to find another of, at least for testing purposes. If you get the power-supply then make sure it's the same type and make (look on your computer and give us the MODEL number for your specific computer, this'll give us the specs we need to determine what kind of power-supply you need). I don't think it has anything to do with your game, but it could very well have something to do with your graphics and/or your video card as well. Is it the power, or the dv15 pluggin (that's the plug where you hook it to the comp itself, NOT power, the other one) that messes it up?

Most likely this is a power-supply matter as you pointed out and that'll require a replacement. Those things cost alot, so if you can find a used computer at the dump or something or go to a local hospital and buy one for cheap, or have a friend with one they don't use cuz it's broke or something i'd do that, but make sure it's compatible!

Hi there,

I've been having some power issues with my laptop for a while. For some time now, my laptop has been constantly losing power and shutting off, regardless of whether I am running off the battery or the power supply. There does seem to be inconsistency as to whether the computer is getting power from the supply (it will be plugged in and off, and sometimes the light that indicates that it's charging will be on, and other times it won't.) I've also noticed that the power supply, as well as the bottom of the computer, get extremely hot. Sound like a bad power supply, or something else? I just think it's weird that it dies regardless of whether it is running off of the battery or the power supply. Perhaps the battery isn't getting power and it thinks it is?

Thanks for your help!

A:Laptop will not start. Bad power supply?

You don't tell us which laptop you have, but the odds are that the power cable connection into the laptop has failed because the socket is coming off either the power controller or the motherboard. An unstable connection can arc and cause heat. You need to get this fixed before it does any more damage and becomes unrepairable. A decent laptop repair should do this for less than $200/100 or local equivalent.

Good day everyone maybe someone can give me some light on this issue I have identified this as being a power supply problem however it may be related to another component within the mother board This is what happens Since a couple of weeks back I ve noticed that my machine sometimes just won t boot up The specifics of the PC hardware I assume are unimportant at the moment but just for the sake supply Bestec Power 250-12Z start ATX won't of explanation let me tell you that we are talking about a tower PC de-branded HP P which as you all know that means it has no support from its OEM Anyhow the problem is that sometimes it just did not start up by pushing the power on button Some of you may think it could be due to a problem with a loose cable or the sort believe that is not the case Well this has been Bestec ATX 250-12Z Power supply won't start going on and off but since yesterday my PC has been even more stubborn to power on Today after even removing all external cables and trying a few things it did not power up no fan no sign of life but just a green light I assume it s an LED just below its power connector that while the problem existed it was blinking green I even removed any cable from the HDD DVD and any other power connector and still the same behaviour Ok after trying this and that I could finally make it boot up by the way I m writing this from the same machine in mention but I m affraid this may happen again and probably it s a sign of something worse to come or just break completely Another thing I noted is that when the light is solid green I can power up which gives me the impression the power supply was in a sort of locked state I ve been looking for any manual or troubleshooting guide from the manufacturer Bestec in order to better identify the issue but have been unlucky so far I wouldn t like to replace it without having more info regarding what is causing it Any ideas or anyway I can find this power supply troubleshooting manual Thank you so much for any reply towards solving my issue regards Moris nbsp

This is a problem I had since a few months, but back then it wasn't that irritating. Sometimes when I tried to start my computer it would start up mechanically, so to say; all the fans were working and so were the HDDs, but not the BIOS. Nothing would happen, and the monitor was ever idle. A simple cold reboot usually solved the problem.

Now, like I mentioned, the problem got serious. The computer won't start at all, i.e. nor the fans, nor the monitor, nor the HDDs will ever start up. It just keeps restarting itself every second without any enhancement. I also found a solution for this problem by setting the power supply to 0, and then back to 1 after a few hours(!). Restarting after just a few minutes doesn't work. What's the matter? Have you ever encountered such a problem?

Hi. Recently got a brand new PC on an auction website and have had nothing but trouble from it. Today it's PSU started making a continuous extremely loud whining noise like a jet-liner taxiing on the airport, and the whole system was going crazy; the OS kept crashing etc, and before long it crashed again and could not be restarted. This prompted some Web research on the PSU (an ISO-500PP 420 Watts) and was not surprised to see that they have got an appalling reputation with fake "technical specifications" on the label. Am not writing this for help advice, as the PSU is stuffed. Primary reason for writing is to warn people, if you are buying a PC make sure that the PSU is not an ISO!!!

So I just recently purchased a new desktop as my laptop fried. I bought this desktop with getting a new video card and power supply in mind. I purchased an ATI Radeon HD5750 which requires one of those 6 pin power cords. The new power supply had what I need.

When i switched out the old 250W for my new 500W, I received no results. The computer would turn on, all fans would run but I would get nothing on my monitor. The motherboard green light would also turn on. When i swapped back to the old power supply, everything still works great. Any troubleshooting tips? Im told that this might not be a great power supply either. Thanks in advance.

Probably need new power supply as on/off switch on back of computer does nothing (won't turn computer on or off by that switch).

However, the ritual I seem forced to follow makes me wonder if that is my only problem--- Let me explain:

Hitting the switch on the front of the computer doesn't usually result in starting the computer-- but what does start it is to unplug the chord from the back of the computer and then plug it back in (unpluggin/pluggin in at surge protector doesn't usually have same results).

I leave machine running 24/7 and it works fine--- however, I am concerned that I want it repaired before it fails altogether.

Your help would be appreciated

A:Switch on Power Supply bad-- and need to plug cord in to start

Having to remove the cord to start is usually indicative of a PSU fault.
Though unplugging or turning off should have the same effect.

PS a "chord" is a series of three or more musical notes...

Why would the switch only work after jumping then removing the jump on the 24 pin???

A:Computer won't start anymore after closing it with Power Supply Switch

Hello and welcome to Techspot.

If after trying your other psu it`s still dead, It`s got to be either the mobo or cpu.

I think for whatever reason, you`ve had a short circuit of some kind and it`s fried either the psu/mobo/cpu.

You`ve seem to have tried all the right things, so I can`t really suggest anything else.

I think this is a fairly simple question.

There is a 20 pin connector that would normally plug into a motherboard. Are there 2 pins in that connector that I can short so that the power will come on right away when plugged in? Ill attach an image of the connector.

A:Computer shut down - power supply problems? - fans start/shot off - not booting

Depends entirely on what the issue is. If the PSU is supplying power but not stably and the board isn't powering up because of that, you could be looking at just a PSU replacement, or various components.

What type of processor do you have? If it is an older model Athlon and the fan was not spinning fast enough, in theory it could have overheated and fried, though that is a rare occurence unless the fan outright stops spinning.

So I turn my computer off one day only to find it wont start the next day. I open the case up and see the led is on. I flip the switch on the power supply off then on and quickly press the power button. My computer starts but the following time I shut down the computer it again wont start and now the led is blinking. I've never had any issues like this before, any help would be appreciated.

I don't routinely use many usb devices, only my mouse and keyboard and every now and then my ipod. I figure the issue is likely either the power supply or the motherboard. The ps is almost two years old while the motherboard is only about three months old.

A:Computer wont start, power supply wont start, blinking led

It sounds to me like your PSU is the problem, get a hold of another and plug it to your computer and see if that will make it start, if it doesn't it might be BOTH your motherboard and PSU. A bad PSU will burn a motherboard.

Whenever the Hard Disk Short DST test fails that indicates that the Hard Disk Drive has failed and that requires a replacement to resolve the issue This issue could be due to Application or driver conflicts, virus issues, file corruptions due to incompatible applications, improper shutdowns, update failures due to conflicts, sudden power surges, if notebook is dropped etc.. HP will provide a replacement Hard Disk Drive if the Notebook warranty is Active, If not you need buy a SATA Hard Disk Drive from a retail shop nearby Please make sure you are getting at least equal capacity as the original one in order to use Recovery Disks. If you need you can buy a larger, but not smaller capacity Hard Disk Drive. For example if you have a 500GB Hard Disk Drive you can upgrade it to 750GB Hard Disk Drive but not 320GB Hard Disk Drive Please try the below shown troubleshooting steps once:Step 01. Remove the battery and unplug the AC/Power AdapterStep 02. Press and hold the Power button for more than 30 SecondsStep 03. Plug in the AC/Power Adapter (leave the Battery out for now)Step 04. Press the Power button and check if the Unit works normal If the above mentioned steps does not help, then you can try reseating the Hard Drive on your Notebook If the issue persists again please Contact HP if your HP Notebook is under warranty, HP would replace the Hard Disk Drive and provide you a Recovery media to restore factory operating system after replacement (if you've not yet created Recovery Discs/USB Media) Note: Back up all the personal data to an external drive if it's possible. Otherwise you could connect the failed HDD via SATA to USB adapter with another PC or same PC after replacement of HDD & re-installation of OS and try copying /recovering the files.

I have a Inspiron 15 3541 touch screen and "misplaced" my power cord and adapter. I'm using a Dell adapter from a different computer, but when I turned on my laptop, I get a message requiring a system or admin password even before it boots up. Is this because of the different adapter? How many pins did my adapter have? What problems does a different adapter create?

A:Power adapter pins

The password that is showing up before your computer boots sounds like there is a BIOS password set on the computer.  Unfortunately if you don't remember that password then you are probably stuck.  You can probably go online and search and see if there is a way to reset BIOS on the laptop and get it to default and remove the password that is set on it.  If there is a hard drive password though then the only way to remove that if you forgot it is to install a new hard drive as the password will follow the drive, not the computer.
Your power supply should have only 1 pin.  Dell used the same adapter for their computers for a while, they come in different wattage though and if you use an adapter that is too low then it may not be able to charge the battery while you use it or at all.  If the plug fits and it is a Dell charger you should be okay to at least get the computer up and running.  If it is a low wattage charger and the setting is set in BIOS (usually is by default) you'll get a message from your computer telling you that the charger isn't powerful enough to charge the battery while in use.

Hey guys so i got a 780 GTX from my friend for cheap to give my computer a little bit of a performance boost from my older card which is a AMD Radeon HD6950.

Now my Radeon used 2 6pin PCI-E connects but the 780 power connector shapes comes look to be a 6 pin and a 8 pin connector. Looking at the cables that came with my power supply (silverstone strider 80 plus silver 850W (SilverStone Technology Co., Ltd.INTRODUCTION?ST85F-P)) i am not 100% sure on what cables to use. I think where it says 2 x 8/6-Pin PCIE connector(550mm)in the connectors section refers to a 6+2 PCIE cable.

can anyone confirm what cable i need to use and include a relevant picture?

A:GPU's that have different connecting power pins (8 and 6)

Yep that's it an 8 pin power plug is usually already split on one end so you can use just the 6 pin or the extra 2 to make an 8 pin.

I ran Dell's PC Checkup and it failed on the SMART Short Self Test. From what I get this basically means my hard drive is going to fail any time, true? When I get a new hard drive can I use the Windows 7 code that's on my computer or will I have to re-buy Windows 7? Are there any tutorials for replacing the main hard drive? Thanks

A:SMART Short Self Test Fail

Well the drive may fail sooner or later but its a good idea to get another. Yes, you can use the key on the sticker on the computer to activate windows. Better still, while the current drive is still alive, just save an image of the windows install using Macrium free or Acronis to an external drive, then you can just restore to the new drive- you wont even need to use the sticker code.

I have a Lenovo Thinkpad T420 with a HDD Since I got upgraded to windows 10 unknowingly by MS , I kept on declining the request to upgrade from windows 7 but one day  it just started upgrading whilst I was away from the laptop, I've started occasionally hitting the error "2100: Detection error on HDD0" So I thought best to do a disk scan and have hit the warnings below on the SMART test. It went through 80% of the SMART test  quickly i.e. 2-3 minutes and then hung on the last 20% ....... shud I b worried ? Lenovo Diagnostics - Log5/30/2016 21:33:54 - SMART Status TestPassed (0.16s)5/30/2016 21:33:54 - Targeted Read TestPassed (1.16s)5/30/2016 21:33:55 - Random Seek TestPassed (89.64s)5/30/2016 21:35:25 - Funnel Seek TestPassed (74.27s)5/30/2016 21:36:39 - SMART Short Self Test5/30/2016 21:46:40 - Critical: Test has timed out: 600 s Warning (600.92s)5/30/2016 21:46:40 - SMART Drive Self Test5/30/2016 21:56:41 - Critical: Test has timed out: 600 s Warning (600.86s)

A:Smart Short Test Failed

Time to replace the hard drive. You can use a retail SATA hdd to replace the 500GB hdd you have. Hope you have burned your Recovery Disk set?

I have read many times that when the Power button on a computer will not start the comp, take a screw driver and short across the Pwr pins on the Mobo. This is supposed to start the comp.
My question is how does that action make it happen? And, will the comp keep running after you remove the short? Is the power switch, then a momentary switch?
I have a computer that will not start either with the power switch or shorting the power pins. The psu is tested good. I believe that possibly the motherboard is bad.
Any thoughts?

A:Shorting across the Power Switch pins

will the comp keep running after you remove the short? Is the power switch, then a momentary switch?Click to expand...

Yes, and yes. Just make sure that you are shorting the proper pins.

A:Hard disk Short DST test failed

Hi, The 24 character error code does confirm a failure of the short Disk Self Test and would indicate that the Hard Drive is failing and needs to be replaced. If your notebook is still under warranty, contact HP and arrange to have the drive replaced - If needed, you can check your warranty status Here. If you live in the US, contact HP Here. If you are in another part of the world, start Here. If you are out of warranty and would like a guide on replacing the Hard Drive yourself, please let me know. Regards, DP-K

Hi,            The failure ID refers to Hard disk drive failure. If the unit is under warranty, then you can call the HP Support to get the Hard disk drive replaced if not you have to get the Hard disk drive replaced yourself and then reinstall the operating system using recovery disk.

HP diagnostics returned error code 9lhvwc-5rg85u-mfh15f-60t903 during a hard drive short self test this evening. Prior to the test, the disk drive was working very slowly, as if it had trouble reading data. I am able to log in with windows in it's normal mode, but the drive performs poorly. Safe mode is better. I own an HP dv7-6175us with serial number 5ch134ijx7.

A:Hard Drive failure during short test

I suspect it's an issue with the header, because the disk drive was also clicking, and it was the click you hear when the accelerometer halts the hard drive. I suspect it's impact/shock damage. It was repeatedly clicking for about 5 time before I shut it down manually.

Please recommend best solution: Clone and replace WD Hard Drive?  If so, what is recommended WD replacement model?
Any other suggestions would be appreciated.

A:SMART Short Self Test - Failed HD521-2W

> Clone and replace WD Hard Drive?  If so, what is recommended WD replacement model? Your current disk-drive is 1000 GB.  So, any 1000 GB or 2000 GB drive will work, without any worries.Anything larger might have an issue, if the motherboard is "older". Note that WD offers a download of free "disk-cloning" software, as long as either the "source" or the "target" disk-drive was manufactured by WD. How "full" is your current drive?  Buy a new hard-drive, and backup all your data/files/music/pictures/bookmarks to it,while your current disk-drive is still working OK.  Or, "clone" your current disk-drive to the new drive. If the disk-drive is still under warranty from WD, WD will replace it.  You might have to pay for shipping it to WD. If the disk-drive is out-of-warranty, WD sometimes has a "customer loyalty" program.You tell WD the serial-number of the drive, and you get a discount on theh purchase of a new disk-drive from WD's online-store, and you don't have to return your current disk-drive.
