I have a Fujitsu A3040. Crashed and goes to ESC Diagnostics F1 to load default F2 for setup. Memory shows good. Says CMOS Chechsum Bad. Any selection leads to a BIOS password that I did not set. I can't find a backdoor password to work. Took entire laptop apart and removed CMOS battery. (located in an impossible place under the speaker panel) Didn't work. Can't figure out who made the motherboard to get a idea where to find the CMOS jumpers. Tried talking to Fujitsu online help. Total joke...they have no idea and cant look up who made the motherboard. Out of warranty so only option they give it to take in for repair. Really hope to fix myself.
I can't change the boot order and have no floppy built in, won't go to CD/DVD drive. Tried a USB DOS Bootable but doesn't see it either so can't run any program to tell me any info on maker.
Anyway.. can anyone tell me how I can tell where to find the CMOS jumpers or how to figure out who made the motherboard? This is what I have so far...
Boot up screen says:
AMIBIOS (c) 2006 (there are no numbers at the bottom to figure out who made the motherboard as suggested on the AMI support page.
Chipset: ATI Radeon® Xpress 200M (RS482M and SB450)
Processor: AMD Turion™ 64 Mobile Technology MT-37 (2 GHz, 1 MB L2 cache) with high-speed Hyper-Transport™ Technology system bus operating at 1600 MT/s
Memory: 512 MB on board fixed memory, one DIMM slot; max 1.5 GB (512 MB + 1 GB), DDR 333 MHz
I have all recovery software and manuals but so far no help.
RS482M shows microstar, but all service manuals I find are for desktops. Perhaps custom made motherboard?
I took pictures of the board if that will help. Board says BOXER2 MAINBOARD02 in white letters but nothing found by searching.
Please help!! I am getting bald spots from pulling out my hair!! LOL! Thanks! Belinda
