How do I check power supply on an emachine T2825

Q: How do I check power supply on an emachine T2825

I turned my emachine T2825 desktop off to move it. I plugged it back in and tried to turn it on but now it does not boot up, nothing on the screen. The blue indicating light around the power switch does not come on but the hard drive amber light is on and the processor fan is on all the time. I have been reading several threads with simliar problems on this PC and it sounds like the motherboard went bad and it is possible the power supply caused it to go bad. I have check my voltages and I get the 12 and 5 vdc at all my plugs. I have replaced the power supply with another 250w P.S. but it still won't boot up with the same results as before. Before I invest in another mother board I would like to make sure the power supply is bad or not. Is there a check for this? Also do these syptoms indicate a bad motherboard?


Preferred Solution: How do I check power supply on an emachine T2825

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 http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: How do I check power supply on an emachine T2825

I would have to agree that it sounds like a bad motherboard...make sure that everything else is SEATED correctly, especially the video card.

You can get a 15 dollar tester from a computer store that allows you to test the P-Supply...Otherwise, you might google on home ways to test it.

Hi all,

I was checking connections on this Emachine T2825 desktop computer and pulled the power supply/switch connection along with two light connections off the motherboard before I had a chance to see exactly how they were connected (bi-focals). The pins are in the corner of the motherboard and there are two rows of eight. Can anyone tell me to which pins they should be reconnected. There are three pairs (red/white, black/white, and green/white).

Thanks in advance!

Ouch. I hate when that happens. Just happened to have a T2825 here, so this is what I see:

From left to right, top row:
[empty] [empty] [PowerSW White] [PowerSW Black] [no pin]

From left to right, second row:
[HDDLED Red] [HDDLED White] [empty] [empty] [empty]

From left to right, bottom row:
[PwrLED Green] [PwrLED White] [empty]

For reference, the mainboard is marked "AU31".

Hope this is helpful.

We have a Emachine T2825 I have already read about many problems these machines have but each is alittle different.
The problem: Left yesterday ( computer is always on) came home and no computer and no monitor. Didn't think much about it, tested plug and outlet and still nothing. I mean nothing no lights , no fan , no noise at all. Took batterey out and still nothing. Decided to do what everyone else thought and change power supply. Still nothing not even one little light. Before this is was running perfectly. We have two sticks of memory and tested them one at a time in each slot. Still nothing. One thing I was wondering was with a new power supply wouldn't atleast the fan come on in the power supply unit itself
or is it all still feed throught the motherboard? another thing is while taking it apart the power, LED & the other one came off and I'm not sure what pins or in what order they are suppose to go back in. Oh, I put my hard drive into another computer and had no problems there. SO, I felt I was down to either
notherboard or CPU. Can ANYONE think of anything else I can try before going out and investing in new components?

First off calm down.

Why would a power supply fan come on if its not powering up a computer? Some may, but its an exception rather than the rule. So using that as an indicator isn't a good idea.

Its likely your motherboard died, there are probably 100 threads on Techspot in the last 3 months with emachines and power supplies and motherboards dying.

You are scaring me with your confusion of pins, is this something where you pulled the switch off the motherboard and that is why it won't turn on? What in the world were you doing by any LED wires when putting a new power supply in?

My friend's computer (T2825) died. Turns out no power. Swap the power supply out with 2 diff. known good P/S.. the system turns on for about 1-2 sec.. Are these Bestec ATX 250 -12E specicially pinned for an E-machines motherboard. looks like theres an extra wire on each side of the 20 pin connector..
Any help is appreciated..

A:Emachines t2825 power supply?

I'd say if there is an extra pin on each side of the 20 Pin ATX, you don't have the right PSU.

Bestec ATX 250 -12E looks to be a HP OEM PSU, while eMachines is owned by Gateway. So again I would question these PSUs as being a proper fit.

I'm in the process of fixing a dead eMachine T2825 power supply and mobo for a coworker of mine. I've found a PSU, but I'm having trouble locating a good, compatible motherboard. I've checked Newegg, Tiger Direct, etc. but no one really carries old motherboards anymore. Here are the specs of the T2825:
CPU: AMD Athlon? XP 2800+
Socket: A (462)
Chipset: NVIDIAŽ nForce?2
Mobo Type: Micro ATX

I would prefer to go with Asus, Gigabyte or any other well known mobo manufacturer. Any suggestions on where to look?

A:Need replacement eMachine T2825 mobo

My understanding is that the original OS won't install on any other mobo than an EMachine.
However, as long as you aren't stuck on Nvidia chipsets: http://www.newegg.com/product/product.aspx?item=n82e16813186029

I have what I believe is a PSU issue with my machine.
Emachine T3265
1 gb RAM (upgraded from 512)
256 mb video card (upgraded from 64 mb onboard)
Otherwise stock.

We recently had need to unlpug and move the machine, set it up, and then a week or so later move it back. The following symptoms occured both times:

Plug PC in, light 'ticking' sound heard. Power button does nothing. No light, nothing. Leave unit plugged in, about an hour later return and try again, and it boots fine, and did the rest of the week. Moved the machine again, and same happened. Two months on, and it still boots/runs like a champ. Have finally had time to do some investigation on what happened and from that I'm learning it may be the PSU capacitors discharging and I should replace the PSU.

The machine has been trouble free otherwise, and does what we need it to do. So, I would rather replace the PSU than the machine if it can be done cheaply enough (say, 60 bucks top end). Obviously don't want to sink a lot into this old machine, but I've never been one to spend money I didn't need to, and if I can get another year out of it I'll be happy.

Opinions on the above, and suggestions on what to buy. Found a Bestec for cheap, but have been strongly dissuaded from them with the 'you get what you pay for' argument. Of course eMachine PSUs seem to be flaky anyway, and this one lasted 6 years, so....who knows. Not me, that's why I'm here.

A:Emachine T3265 power supply

Sorry, You Missed a Better Price by a Week.......

Buy one of these; Antec EA-380D http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033 It'll probably outlast the Emachine.

In some cases it's the motherboard that fails in the Emachines, and the symptoms are similar. Look for signs of overheating , burning. and or swollen capacitors around the Processor before you sink money into this machine.

The Bestec PSUs are garbage. The 250s can take out the board when they fail, the 300 (watts) are less lethal when they fail, but fail they do.

Although I've seen this Antec cheaper, it does come to $51.00 USD, with shipping, which meets your criterion.

Bear in mind that the most prudent thing to do in your case is to substitute the PSU first with a known good one, but I realize that that isn't always possible.

Have you searched the forums for reference to e-machine PSUs? This is a common problem so it would be worth checking and seeing what others have done.
250 watt is too low - 350 is minimum; and replace as soon as you can before it takes the motherboard with it.

My sister-in-law has an eMachine that she turned off and unplugged before leaving for vacation. A week later she returned and plugged it back in only to find it won't turn on. I don't know much about this pc other than it's a tower and about 3 or so years old. I figured it was probably the PSU (power supply) but wanted to verify as many things as possible. Basically, there is a green light on the back of the pc (on the PSU) that will flashes on and off when you try to turn on the computer. The PSU fan doesn't spin and nothing else makes any attempt to turn...just dead.

I pulled all the power connectors and jumpered the power switch pins (15-16), this gave me a solid green light on the PSU and the fan spun normally. I tested with a voltmeter and got the proper voltage on all the pins. I am thinking that this probably rules out the PSU but not 100% as something could be 'pulling it down'???

Any ideas on what else to look at? I hate to buy a PSU when it appears this one is ok. That pretty much leaves the MoBo and/or CPU. I've pulled all the cards and memory trying to get it to do anything and nothing affects it. I suspect there is something wrong with the MoBo but don't know how to verify that.

Any help or advice is appreciated. Thanks!

A:Power Supply check

Hi Panais,

No software that I know of, you can use a multimeter to check voltages on the various lines and thus work out current draw on the PSU and thus the power.

The easiest way is to add together the power "wattage" rating of each of your components (info should be available in documentation or on manufacturer's web site) a total of all the ratings at their highest load figure should give a worst case figure which should be less than your rated peak PSU output. The total of the "normal " Load figures of all the components that are working at the same time should be less than your continuous rating for the PSU.

This is of course an exercise based on quoted figures each component is different and also may vary over time.

Is this a general question or do you have reason to think the unit may not be upto the task?

I probably need to replace my power supply in my computer with a more powerful unit. How do I find out the output of my current ps?? Are they difficult to replace yourself or should a pro do it?? Also whats involved in replacing the cooling fan yourself? Im upgrading my pc to play games.

A:How do I check the specs of my power supply?

If your Dell computer was manufactured after August 1998, it may require the use of a proprietary Dell power supply. Although the Dell power supply looks like a standard ATX, it is a non-standard PSU that cannot be replaced with a standard power supply alone. Because of this design difference your Dell Power Supply may need a Dell to ATX power supply converter in order to be replaced with any standard ATX Quiet Power Supplies.

Pentium 4 Dell Models that do not require a power supply adapter:
Dell Dimension 4300, 4400, 4700, 8200, 8300, OptiPlex GX 400

Pentium 4 Dell Models that are not compatible with this power supply adapter:
Dell Dimension 8100
open the case from the side
Remove 4 screws on the back of the power supply
Unplug everything from the power supply

Reverse the process your done. No real big deal. just make sure you know the power supply you purchase will work with a dell or the adapter you but with the power supply will work as well.

How do I find out the output of my current ps??
Look at the lable on the power supply it will tell you.

Also whats involved in replacing the cooling fan yourself?
Depends on what fan you are speaking of? the case fan? not much just remove it and replace. if your speaking of the cpu? a little more in depth, the stock heatsink+fan usally work and no reason to change unless overclocking.

I have 2 failed Z800 power supplies (1150 watt version). After some internet research I am led to believe this is a common problem and related to the PS capacitors. Since I do not know how to do this capacitor replacement (yet). I thought I would buy a new PS. However, I do not want to buy a Z800 PS since it seems to me to be a defective design. Can anyone chime in and tell me if the new z840 1125 watt PS will work with my older z800? I have called HP support and spoken with the correct support people on this and they were not able to confirm if the Z840 PS will work (fit) on the z800. The closest confirmantion I recieved was that if it fits then it should work. Instructions to fix the capacitors:http://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Z800-power-on-issue... Same issue I am facing:https://www.youtube.com/watch?v=f563JGeoxaw On a side note, can anyone recommend a good service tech to make such capacitor repares in Southern California or insrtuctions on how to make this repair (with pictures). Thanks

Hello All,

Just thought someone could give me some advice........

I have an Emachine Model W2646 that isn't powering up. I tested the power supply in a different PC and it was definitely dead. So I order a new Power Supply the same exact model and everything but the PC still will not come on the only different this time is that the power button is lite with the new power supply installed. However nothing else still won't power up, no fans running on the Power Supply or the CPU fan. I'm clueless I even tested the new Power Supply in another computer and it worked perfectly. I'm thinking the only other problem could be the motherboard. Maybe when the old power supply failed it took the motherboard out with it. I really hope that's not the case, but there doesn't seem to be any other alternatives. Sure could use some advice as of what to do next .

And Thanks In Advance For Your Suggestions.

And... that was it. No H/Ds spining, nothing, Nothing displayed on the monitor. All the new Power Supply did was lite up the green motherboard LED.
Anything you kind folks can think of? I swapped RAM, unplugged each Drive unit, even swaped the H/D just to be sure. Cant boot into Safe mode either. Im suspecting a Motherboard too? Whatcha guys think (I know, I know.. its an EMachine...)

I have an eMachines desktop I've had for three or four years. I've heard about what crap these machines are, but mine has done right well until very recently. Starting a few days ago, the machine shuts itself down suddenly and with no warning.
When it does this, the power is still on, but the screen is dead and it won't respond to the keyboard or mouse. The power light, instead of being on solidly, is blinking. I have to cycle power to get the machine to come back on.
This can happen in as little as 20 minutes after turning the power on, or the machine can run all night without issue. I can start it from a cold start (when it's been off for a day or two) and it might crash in 20 minutes. Or it could have been running all night and I'll use it for a few hours before it crashes. So I don't think it's a heat-related problem.
A call to eMachines was useless. When they heard how old this thing is, they just snorted.
Any ideas where to start?

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!

A:emachine Askock motherboard power up?

Hi Zapster,

If you were refering to the CMOS battery when you wrote "onboard battery". I don't believe that is the problem. If the CMOS was bad your BIOS settings would not be saved, but it should still boot. Even though the fan spins, you may have a power supply problem. I would make sure all the connections in the computer are secure, make sure the memory is seated correctly and in the correct slots, then try booting again. If you are not able to boot then I would try another power supply or systemboard. I hope this helps.

My son has an eMachine model 2825. It is only 2 years old. One minute is working fine. He walked away for a few minutes and when he came back the monitor had the OSD up but you could not control the screen. It almost appeared frozen. So, naturally I first tried to restart the machine. The same thing happened on startup. I turned the machine off and tried eMachine support...useless because it's out of warranty. When I attempted to power it up again, nothing happened. The fan didn't come on...no lights. So, I replaced the power supply. Now it comes on but doesn't attempt to boot. The OSD comes up on the monitor. My other son had a newer eMachine. I've tried the monitor with his tower and the monitor itself for the 2825 works fine. When I tried a different monitor with the 2825, it was blank. I'm assuming that the OSD comes on because it isn't getting a signal. Any suggestions as to what I should try next?

A:eMachine has power but won't even attempt to boot

Make sure you got ALL cables reconnected properly (incl. the P4-cable if it has an Intel CPU). Reseat memory and any cards you have. Check that all fans are plugged in and working at bootup.
If you got an exact same replacement powersupply, that's your problem.
Emachines are crappy to begin with, and the parts they use are mostly in the same category.
Return that PSU and get a brand-name PSU, such as Forton or Enermax or Antec, with minimum 350W.
Or borrow one like that from a non-emachine PC (or your friendly neighbour) just to be sure.

Hello all,
I too have fallen victim to the emachine psu/motherboard death saga.
In the course of trying to daignose the problem I managed to lose unknown parts of my power button.
I have already bought a new psu (hoping that was all it was) and am awaiting arrival of a motherboard.
But I am in need of a power switch.
I guess I could just make a new hole and install an aftermarket switch but would like to either find a switch or another faceplate. I beleive the 2542 is a nexgen chassis??
With all the horror stories about these machines one would think someone would have a dead one they would be parting out.
Any help You guys could give me with this would be much appreciated.

I had a short in the computer, but I don't know where. It would start to come on then stop. I found that tilting the tower, waiting for the computer to start and setting it back down gently worked. Then it worked for a few months without even having to do the tilting/setting it down gently routine. A few days ago, I had to move it to upgrade the memory. After I installed the card in the slot, I tried to turn on the computer. It will not come back on. At first there seemed to be a short in the button on the front. I've removed it and touched the two wires together. SOMETIMES, not every time, this will cause the fan to start and a light on the front to come on but this lasts a few seconds. I hope you can give me some hope for remedying this. I about ready for a new computer anyway, but I'd like to get some of the files off this one first.

My first thought would be a failing pw supply. Emachines come with junk pw supplies and very often fail.
Easiest way to test would be to swap in a known good unit.

If you just want to copy some data files from the old computer, you can simply pull your hd and connect it to the system you buy. Copy whatever you want.

If you are intending to buy/build a new system, I would think long and hard about putting any money into an old emachine.

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!

A:Power Supply makes clicking noise when I press power button

You may just need to drain the power off from the power supply and try again. Unplug the power to the power supply, press and hold the power button for 30 seconds, then plug it back in and try to turn on the computer again. If that doesn't put the old power supply back in and see if the PC works, or was the old one dead? If the PC works with the old one and not the new one then you may have gotten a faulty power supply.

I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.

A:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply? A nice feature of the laptop is that you can watch DVDs without powering up the Windows operating system (it has a small linux OS for the DVD player). Granted, the DVD drive and screen are prob...

I have an enquiry relating to video cards. In order to do my job, I need to get a card with at least 512MB of VRAM, preferably 2GB. However, the ones I've found online use 300w What's the maximum watts that I can use with my Lenovo H520s? And what would happen if I used a 300w video card in it?

Use a power supply calculator to get a accurate calculation of your power requirements.   Graphics card manufacturers have to figure a worst case scenario when giving power requirements.
Mod:  removed the Newegg calculator, which only gives a recommended psu size, rather than a power calculation.   The CoolerMaster gives both.

Ever since i got this new motherboard and CPU ive been having a bit of a nightmare with it.

Gigabyte ga-ma790fx-ds5 -Latest Bios
AMD Phenom Black Edition 9850,
4 gigs PC 6400 ram (Corsair XMS2 CM2X1024-6400
ATI Radeon 4870

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)

It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.

A:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

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?

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 have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.


A:No Power, Blinking green light on power supply and motherboard

Sounds like a Power Supply problem.

Hello guys.  Can anyone help me understand the power supply on the HP Envy Phoenix 860-019?  The PCIE connector 6 pin connected to the GTX 960 has black and white wires.  Shouldn't there be yellow and black wires?  Yellow is usually 12 volt and black wires ground.  Is the 6 pin connected to my GTX 960  supplying a standard 75 watts of power or something else?  I want to install a GTX 1070 but the 6 pin wire colors are not the industry standard color scheme.  Also there is a 2 pin power connector with a white and black wire.  Usually a 6 pin and a 2 pin can be used together to connect into a 8 pin socket on a GTX 1070.  Will my connectors supply the needed power and connect properly because the color scheme on the wires make no sense. Thank you
