Hi,
i have some doubts about these steps:
- Power off the board ((ok!))
- Remove the battery ((ok, but when do i have to fit it again?))
- Disconnect from AC power for 20-30 minutes ((with or whitout battery?))
- Do a BIOS recovery ((BIOS RECOVERY or BIOS UPDATE or both them?)) from usb with BIOS version 109 Intel® Download Center ((with or without battery?))
I'm asking because the tutorial video (Desktop Boards — Instructions for Recovery BIOS Update) first learn how to RECOVERY BIOS removing the jumper and turning on the machine without jumper. (((((In this step nothing happen in my PC: the fans spin, but nothing is shown in the screen and doesn't matter how much time the pc stays on. So when I turn off the PC and replace the jumper to "normal" place and turn on the PC, the INTEL BOOT screen freezes and all commands (F2, F7 and F10) do absolutly nothing. So I turn it off ))))) After BIOS RECOVERY the video learns how to update the BIOS (In this one, I'm still waitting the unfreezing intel boot screen ).
I'm really really thank you for your awnser, but it seems we are far away to solve my problem
And sorry for bad english.
