Apologies -- incredibly new here. I bought a clip, I have a Pi and I'm about to (hopefully) dump my password protected BIOS. I found a "Winbond 25080dvsig" chip -- which, I think is the BIOS chip. Does this sound correct?

Also -- when I'm using the clip/Pi to take a dump of the BIOS, do I need to remove the battery from the laptop first? (Old plastic makes me nervous)

Tried the BIOS provided but no change, board is having power for few seconds but not posting.
i just saw this board has one more bios chip.

from the sizes it seems different.

can someone please advise, which one is the main and what is the data stored on the second chip?

Hi, I have a C930-13IKB That charges and has caps lock, but no image on internal or external screen. I think the BIOS is corrupted.

NVM, I powered the board on with the motherboard removed, and now it is displaying to external screen, so I seem to have another issue as the board booted to login screen on the bench.
