Re: Need bios fujitsu lifebook ah54

thanks for the response i think this is not a bios problem.the problem with this laptop it turns on but no display, if i connect to external monitor signal goes to external i mean external monitor from orange light becomes to blue light but no picture on the screen.I double check again the components on the board, i found that there is a burnt ceramic caps near lvds connector, when i removed it still no image on the display. Anyone could help me on this and what is the purpose of the ceramic caps that burnt.please help

There`s no schematic available. Can you still post your bios backup, it could be corrupt.

Observe carefully under a microscope or magnifier around the burnt cap. I beleive track is damaged and you need to find that track and bridge it with some wire.

Re: Need bios fujitsu lifebook ah54

it might be nice also if you'll make appropriate post back on the main thread so a lot of users will see it and help.

donating your bios dump here might help others.
