Question about System Power Supplies

4 Answers

Emachine w3052 sempron 3000 Power supply gave off a warning buzzer in the middle of the night and I pulled the plug. Next morning I had no juice to anything. Bought another powersupply and changed it. No juice to anything. Tested the switch in front of tower, it's ok. Changed the lithium battery. Still no juice anywhere. Bought a generic powersupply specified for my model. Now I have juice to all drives and cpu fan but PC won't boot. HD is fine im using it now on this PC. Have it set on master. This new power supply is a switching power supply where as the old Bentec was not. The front switch on the pc doesn't light up blue like it used to. I'm wondering if I need to change anything on the motherboard switch pins or power pins?? I'm afraid it maybe the motherboard but it smells fine and I see no hot spots on it. Am I forgetting anything else???

    One of you guys mentioned the Rom chip on the Mboard maybe fried,,, I'm assuming that's the 32 prong PMC FLASH chip for the BIOS settings. It is in a sink and looks replacable w/o having to sauder, but Wouldn't I have messed up the settings by repacing the battery as well. If so how would I reset it if the DOS menu doesn't boot either.

This is mother board failure. i would pull the board for a visual. try to find any discolorations that may lead you to the problem. the previous pin selections should match up to any aftermarket power supply.

It sounds like your rom chip on the motherboard has gone.

    So you bought a 3rd powersupply and then things started to work again? But the pc is not starting up. I would suggest trying to reset the bios, there is a jumper on the motheboard most cases close to the battery that can reset the bios. Also I would suggest taking out all the ram memory fom the computer. Then turn the computer on without ram memory (ofcourse unplug in the middle) Then you should hear beeping from the computer, turn the computer off. Place one of the memory modules back in.

    Now you should get a start up screen, if not, try reseating the video card the same way you just did with the memory.

    To reset the bios on this motherboard, you need to pull the jumper and place it back on the other position, let it be for a minute, the computer needs to be turned off and unpluged, the 3volt battery will provide the power it needs.

    Then place the jumper back into its original position, the bios or cmos is reset try turning the computer on.

I have an emachine t5026 that won't turn on. It sounds like a car tying to start and the lights on the front flash as does the light on the mouse, but it won't start.

Hi. I returned from vacation and turned on my power strip and monitor, tried to start my emachine t5026 computer and got nothing. the power light on the back of the power supply is off. If I unplug or...


Your Power supply is most likely dead.

A power strip is not sufficient protection against black outs, brown outs, power surges and other electrical interruptions that occur in the house. Many PC components are very sensitive to fluctuations in power and power supplies often are among the first casualties when a serious problem occurs.

To protect yourself against these common power issues you should invest in an Uninterruptible Power Supply or UPS. A UPS is basically a battery backup that will provide power when brown-outs or black-outs occur and will protect the delicate electronics in your PC. You can purchase them at most stores that sell computers and components.

Emachine won't turn on


With an Emachine it can be the power supply or the motherboard.

My guess it is the capacitors on the motherboard. Check to see if the round cylinders on the motherboard are bulging on the ends, and possibly rusty looking. Esp around the Main CPU/Fan.

They are notorious for bad capacitors.

If the caps look good, it still could be the motherboard, or maybe the power supply. Switcing out the power supply is pretty easy.

Unplug
disconnect all the power connectors
unscrew the 4 screws on the back of the computer
remove and replace the power supply.
Make sure you get a power supply with as much power, or more is much better. 350 watt or higher.

Computer will not turn on


Best way to check is to open your case. Near the power supply plug to the motherboard should be a little led light. If it is getting power to the board this light should be green. If it's unlit then most likely your power supply has gone bad. Hope this helps.

Randy, a power supply is relatively cheap even for a good computer.I suggest you should get a new one and get rid of the old one...you can't scrap it for parts especially if it's burnt or shortcircuited...Hope it helps, have a good day.
