"you should always call panasonic tech support at panasonic headquarters for the proper way to remove bios lock. there are different ways to do it. if you dont do it properly you could do damage . i damaged the cmos socket just by removing the battery…its a good thing i’m skilled at soldering. I was able to re-solder the cmos posts to the board and i put a drop of epoxy between the cmos socket and the reset socket next to it in order to bridge them together so that it wouldnt happen again
