Question about EliteGroup L7VMM2 Motherboard

1 Answer

One problem, followed by another, followed by another

My friend has an emachines T2200 which uses the L7VMM2 version 1.0 motherboard. Two weeks after adding memory, his USB keyboard stopped working. It won't work on my computer either.
The next night, his PS/2 mouse stopped working. It doesn't work on other computers. My mouse worked fine on his computer, until he rebooted. Then the video signal would not come through to a normally working monitor. After 3 reboots, the video came back. After another reboot, no video again. There is also no BIOS beep.
The next night, we noticed the power LED on his case would not turn off, unless you unplugged his power supply. In addition, my keyboard will no longer be detected by his computer.
His harddrive, CD, DVD & Floppy drives are all able to be seen on other computers. We can't test his power supply on my computer, as my MB uses 24 pin connectors and his supply is only 20. However, I tested my 20+4 on his board and got the same error. As a matter of fact, the PSU's fan ceased working after the test.
It sounds like the motherboard to me. Does anyone agree? Also, what might have caused this?

    I've checked the motherboard for bad caps previously. After your post cosisf, I re-checked the motherboard for marks and bad caps & also checked the power supply for burn marks.

    Most of the problems have occurred here at my house. My house is only a year old, whereas, the house the computer is usually at is much older.

    I do know that I have a much newer computer and that I haven't had any problems with any of my electronics in this new house, until now.

    And, like I said in the previous post, my power supply's fan ceased working when I connected it to his board. I think he has some kind of surge or short in the motherboard that is feeding back to other components and frying them. Thus far, a keyboard, mouse, video card and a PSU fan have all been fried by this motherboard

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 ... )

SOURCE: Installing Graphics cd in AGP slot...

Usually you need to disable the on-board video/activate the AGP slot in the BIOS before adding the video card. (Check your manual for entering the BIOS - often hit F1 or F2 (or enter when prompted) as you start the computer before the OS starts loading.)

I have no idea how you see the BIOS information without a working video to start.

A) JP5 jumper is right below the Ram Memory slots.
CPU Frequency Jumper.
(Processor; change internal clock frequency - jumper)

Vertical placement. 3-pin jumper. The TOP pin is number 1 pin.

With the jumper on Pins 1 and 2, the frequency is 100MegaHertz.
With the jumper on Pins 2 and 3, the frequency set is 133MHz.

B) The small 4-pin connector above the CMOS battery is for an internal speaker. (For BIOS Beep Codes)

The small 3-pin jumper that is Horizontally placed above it, is the JP1 jumper.
Clear CMOS Jumper.

The pin all the way to the Right, is the number 1 pin.

With the jumper on Pins 1 and 2, the setting is Normal.
With the jumper on Pins 2 and 3, you are trying to clear cmos settings.

From manual;

"To clear the CMOS memory, disconnect all the power cables from the motherboard, and then move the jumper cap onto the CLEAR setting for a few seconds."

Ummm, NO.

Unplug the computer from power. Put the jumper cap on pins 2 and 3 for 5 seconds. Remove from Pins 2 and 3, and put back on Pins 1 and 2.
Plug the computer back into power.
WAIT 1 minute, turn the computer on.


I don't see any other jumpers. Post back if I missed one, in a Comment, and/or for additional questions,

Need jumper settings for L7VMM emachine motherboard someone removed all the jumpers. c1641 emachine

ECS made three versions of the L7VMM mobo.

1.L7VMM ver1.1
2.L7VMM ver2.0
3.L7VMM ver3.0
(And revisions in-between these)

So without asking you what revision number is on your mobo, (Motherboard), I compared the specifications out of the Motherboard Manual for the L7VMM v1.1, L7VMM 2.0, and L7VMM 3.0, to the specifications of eMachines Support for the eMachines C1641 Desktop computer.

eMachines Support page for the eMachines C1641,

(Click on the + sign next to Specifications)
The Specifications of the eMachines C1641, match.

All three of these motherboard's spec's fit. The revisions has nothing to do with the motherboard chipset used, processor socket, ram memory, or any other major hardware component. The jumper settings are the same.

This is why I feel comfortable with giving you the link to ECS Support, and the Motherboard Manual download page,
for the ECS L7VMM ver 2.0

Disregard the following if you know how to download a ZIP file, and unzip it. (Unzip. Save it to your computer)

ZIP files are compressed files. When a file is too large to easily send over the internet, it is compressed. One method is to make it into a ZIP file, or ZIP files into a folder.

On the above ECS link, scroll down to the very bottom of the page where it states,
English manual for L7VMM2 PCB : 2.0
Release Date: 2003/03/28
File Size: 829KB

Now you have to chose a Server download site. You're supposed to choose one that is close to the country you are in.
I usually choose China, because it is a fast download server. Not because it is close to my country. (The file will be in English no matter where you download from)

Go to the blue down arrow with China to the right. Left-click right on China.

A small window will come up. Left-click in the middle of the empty circle to the left of - Save File. (A green dot should now be in the middle of it)
Go below to the right, and click on OK.

Watch the download progress bar, let the file download all the way.

Now, if you do not have your downloads set, to download to your My Documents folder, this file will be saved to your desktop screen.

(A yellow folder icon with a zipper on it) (Windows XP - Click on Start>My Documents to go to your My Documents folder)

In either place Double-click right on the file name. In the next window that comes up, go to the top Left, and click on Extract All Files.
In the small windows that come up click on Next, Next, and Finish.

Now you will have a small window in front of you with a Adobe PDF icon, and the file name to the right of it. L7VMM2 (2.0)

Double-click on L7VMM2 (2.0)

You are now looking at the Motherboard Manual for your eMachines C1641 Desktop computer. (ECS L7VMM2 v2.0)

Page 13 shows you the factory settings for the Jumpers.

Have any more questions? Just come back and state them.

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.

Need wiring diagram for emachines t2200 motherboard

If you are replacing the power supply and it has 4 pin 12v conector and your motherboard doesn't, just disregard the 4 pin plug. The 20 pin conector will supply sufficient power for the processor. Many of the older motherboards did not have a separate 12v supply for the processor.
