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

New power supply does not work...is it the motherboard


well there are two ways to to figure out which item is broken first you can hook up the power supply and test the pins in the plug with a voltage tester to see if it has power. I do not recommend this approach if you are unsure of what you are doing the voltage coming from a computer power supply is very dangerous. the second thing you could do is attach a different power supply to *********** board if ti works the mother board is good and it your power supply that is busted. Also make sure to check the back of the power supply and make sure it is set to 110 and 220 voltage because this can cause your power supply to not function correctly. It will be a little red switch on the back that says 110v on one side of it and 220v on the other.

I hope this helped.

Thank you,
Norse

Will not power up


This is a common problem with Emachine motherboards, the problem is the power supply is a best tech and allows voltage surges to the motherboard which fries it too. If available you usually have to replace both the power supply and motherboard. I do not know what exactly goes bad on the motherboard but I have replaced many emachine power supplies and motherboards. The motherboard kit which used to be available from Emachines included a power supply and no warranty if you didn't change the power supply. They knew they had a problem.

MY BROTHER JUST GAVE ME THIS MOTHERBOARD FOR MY EMACHINE AND SAID IT CAME OUT OF AN EMACHINE, WHAT POWER SUPPLY DO i NEED TO INSTALL? Intel D845EPI Motherboard


i have seen those in some emachines but the original power supply stinks the processor needs a power supplie the has at least 300 watts but 400 plus is a better choice depending on which emachine case to have it might need ti have the case modded to fit a larger power supplie some emachine case have a plate mounted the allows both power supplie type to be used the small power supplies are garbage so go with the larger p4 power supplie most all should be able to be modded to fit in you case. Just remember the more power in mean the more power out.

L7VMM2 wont boot (no post) plz help


Sounds like the CMOS battery on the motherboard needs replacing...i would try clearing CMOS first, replace battery and test voltage at the CPU (through the BIOS) If that dosen't help you likely have faulty capacitors.
If you get it to boot, im sure drivers and BIOS will need updates if it's been stored 2 yrs.

Not getting power on my t2882 e-machine.


I am an emachine specialist. These computer suffer with problem motherboards which often blow the power supply unit. Replacing the power supply on it's own does not solve the problem as the motherboard processor socket is the cause of the problem, the fault in turn blows the power supply. The same applies to all Advent and Medion computers sold via the high street stores.

1. check power supply watt 400/450 and same another power supply install and check it. if power supply change and system is working ok so problem in your power supply.

2. check CMOS cell on motherboard,(3 volt)

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

W2646 crapped out


Some eMachines computers (like many from Dell) use a non-standard pin out for their power supplies, so if you try a standard ATX power supply it may not function.

However, in my experience it IS likely to be the motherboard. Luckly I have been able to replace quite a few of the eMachines mobos with a standard mATX mobo, since you can probably remove the IO plate. You'd certainly want to replace the power supply when doing so.

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 ... )
