Lenovo W541 BIOS Chips

[DaveDD]

Just bought a used Lenovo W541 and it has the supervisor password set. I know I need to copy the BIOS chips. But for the life of me, I can not find the 8-pin chips on the motherboard anywhere.

Supposidly there is a 4MB and an 8MB chip. I've looked this board back to front and even sideways if that would help.

Does anyone have the chip part number or the silkscreen U number that I should look for on the PCB. Even a photo would be greatly appreciated of where these two chips are located.

Thinkpad W541
Motherboard model: 20EG
Bios revision: 2.41

Thanks for any help,
Dave

Found them.

The description and the picture were a great help.

Just didn't realize I had to disassemble the entire board from the magnesium alloy tray. My little piece of cardboard to track the screws now has 31 screws in it.

Now onto fixing the SVP issue.

Thanks to all for the help.
