    Hi,

    I used my EZbook3Pro with a lot of fun but lately the device does not turn on again. When I press the on-key it will light up the blue led, but that is all. The screen stays blank.

    After pressing the on-key for more then 14 seconds it still does not boot up properly, it does not even show the bios screen.

    Anyone had the same issue and fixed this somehow?

    Bios is V6.

    Yeah all looked at, but fixed it eventually by again writing the same BIOS file to the EEPROM. Now it works like a charm again. So this item can be closed and marked as “Solved”.

    So you screwed around with the Bios before? Might be worth mentioning in your initial post.

    I was able to boot the system and have a bootup screen. I could go to the EFI shell and do the bios flash from the command line as described by one of the posts on this forum.

    If you don’t have a EFI shell, then you need to program the bios via an USB EEPROM programmer and a clip. The old fashioned way.

    Well, I never did that so I don’t have a clue what you need to buy nor know what to do to get it working again. Sorry

    Ok, I studied a bit, and seams that the BIOS Chip is a 1.8V device, so I’ll need an “adapter” for the programmer … I’ll see
