Power Supply for L7VMM2

Need you help with an eMachine c2280. Had to change power supply after power outage in area, but with new power supply there is no power to the m/board (L7VMM2). What else could be wrong?

    Thanks for the reply. Another question if there was problem with the board should I have seen some tell-tale sign on the resistors?

  • cathiepie Jul 09, 2008

    PSU died and was replaced. New one works and machine will start up . Power light is orange and stays on only for a few seconds, the boot sequence occurs and lights up all of the drives in sequence. The fan on the motherboard runs and the motherboard led1 light is on and stays red.

    There is no output to the monitor, but the monitor tests fine with another pc. Where do I go from here?

    LED1 and the fans turn on, but nothing else seems to be happening.

    I have the same problem. Not the cmos battery, not the video unless there is a jumper to bypass the onboard video I dont know about [I tried 3 pci cards], not the power supply (old one works, but tried brand new one. Could be the bios chip (shot) since there is no POST, or mpu, or mother board. Not the memory chips or slots as far as I can tell, had to remove them to re-seat the mpu so I tested them one at a time. Sooo, looks like it's the motherboard, since I wont be able to tell if bios accepts zapping, I will canabilize what I can and buy a $28 "Tiger special" motherboard that uses the same **** and run it until "IT" burns out. Cheap junk anyway!

Well,if you are sure that the new power supply is new and ok,than more than sure,if you dont have any response from the mainboard,that it is damaged by the high tension who allready burned your initial power supply.
I suggest you to visit a specialised service because for now its nothing you can do more.but first be sure you have a quite functional new power supply.
bye

My e machine computer will just shut off after 5 or 10 min.,


I had an Emachines W3609 that did the same thing, I changed the 350-watt power supply with a 550-watt and it still shut off, even using the newer one. I thought just the first one was bad but I guess not. It had more than enough power to power it up but nothing. And it used to randomly restart at times and then just shut off. Try and get a new hard drive maybe that will help. Good luck!

Ok i have a emachine c2280 we put a new power supply changed the ram and i have no video, there is also a red light next to the ram what isit..


Anytime. Just in case you there is any way you can get video to display. There is a setting in bios to change what controls the display adaptor. You might want to try to reset your bios and see if you can change this setting. Figure there is nothing you can hurt at this point.

Just remove the "watch battery" that is on the motherboard for a couple minutes and try to start the computer. Also you might want to look for some pins on the board that say something about bios reset jumpers. Normally you short the two pins then remove and boot. Sometimes you short-boot-shutdown-unshort-boot again.
I'm thinking though if you can get in there you can set your display to pci or agp or whatever kind of video card you have.

NEED POWER SUPPLY FOR ELITEGHROUP L7VMM2 MOTHERBOARD


There is no specific power suppl that you need. The only differce is the wattage 300, 350 , 500 etc. Your motherboard will work with all types not to worry. The only reason you get a higher wattage power supply is if you plug in a lot of stuff. say you have 3 HDD and 2 CDROMS then you would need the 500 Watt power supply.

Hi dallasblue08,

Here's a diagram of what your looking for:

The following eMachine models share the same motherboard (and thus the same front panel layout):

Cant get any picture through the moniter tryed agp vidieo card and pci vidieo card still nothing the motherboard is out of emachines c2280 L7VMM2


Sounds like you have a bad power supply or motherboard. The power supplies in eMachines are not known for reliability, so try testing the system with another one. If you still have no video, you should replace the motherboard.

L7VMM2 shuts down


I think you have overheating problems
Check all fans are working and vanes are clean including power supply one
Check heat sink on CPU that the vanes etc are clean and clear of dust and fluff
Give case a vacuum out including all vent holes also the ones on inside case of power supply
see how you go this problem is usually the cause of persistent reboot

T2085 will not turn on


it does sound like a power supply. you can pick one up for around 80 bucks retail. they aren't that hard to install. 2 plugs on the mobo and one for each drive you have installed. all you do is unscrew the current power supply (4 screws on the back), then unplug all wires connecting the power supply to the components. then take out the old power supply and work in reverse with the new power supply.
if the computer doesn't work after that, it is possible that you need a new mother board. in that case, personally i would return the power supply and start looking for another computer.
but hopefully it is just the power supply.

One problem, followed by another, followed by another


it seams that the motherboard has some power problems. Check on the motherboard for burned or blackened components, or for capacitors that are looking like they are going to blow (inflated on the top), u can do the same to the power supply.
If so change it !
Also maybe the power of the house has problems that the computers power supply cant handle (that can ruin the motherboard or other components )
U can also try to isolate the motherboard from the case (there might be a short between the motherboard and the power supply through the case metal ... )
