Dear all,
I did my first laptop repair related to a BIOS issue. Laptop is a Lenovo ThinkPad T480, and was not booting. With my brand new programmer, I did a back-up of the current not working BIOS, erased the BIOS chip, and flashed this dump: https://www.badcaps.net/forum/troubl...83#post3686683

Hello , for some time I was studying Quanta U9x/8x schematics and the option to use both type of screen (LVDS 40 pin / eDP 30 pin).
In some cases to use LVDS screen PCB use converter IC RTD2132/6
Now I found an HP 15 F series U99 mainboard with RTD chip not populated and LVDS 40 pin lcd touch screen
at the same time I have another HP 15 N series with Quanta U92 mainboard and RTD2136 with eDP 30 pin lcd screen (no touch).
Maybe someone more experienced in the subject can clarify if is posible to change type of screen used with some resistors / bios options change.

Hey,
I have been trying since 2 days to get this working.
The Acer VN7-791 had the 30 Minutes shutdown issue.
Therefore I desoldered the BIOS, cleaned the ME Region (with the Win-Raid guide) and Flashed the Version again.
It seems to have solved the reboot issues.
But unfortunately now I cannot turn off the computer anymore. It just reboots when I do it via Windows 10 or the Power Button. Only thing working is hard Reset via long press of the Power Button.
I tried to install an older Version of Mangement Engine...
