Update:

Found boardview and schematic if anyone is interested. Although the boardview is marked FX503VM_FX703VM, the motherboard code in the filename is the same as my GL703VM motherboard and the board layout is correct. I can't seem to find any mention of the FX703VM. Maybe the FX703VM & GL703VM are basically identical???...

I wanted to clear the BIOS password that my son had added to his laptop (and had forgotten). After reading about clearing the Lenovo laptop BIOS passwords, it seemed that I should be able to dump the existing BIOS and then simply re-flash my BIOS dump back to the chip. I read that this process...

Hi, I've been an electronics enthusiast for many years now, I started by designing systems for art installation projects and my interest has grow over the years. I love hacking hardware to do things that is was never intended for. I am particularly interested in embedded systems and micro controllers. Amazing to find this forum, such an immense repository of information on here. I can't wait to grow this hobby of mine.
