Hi,
I bought a second hand laptop - Gigabyte Aero 15 OLED SA.
It mostly works as expected but it has an issue:
Whenever I make ANY change in BIOS, the built-in dispaly remains blank but a display connected over HDMI works fine once booted into Windows.
Windows in this case shows that HD 630 video is not working properly so everything is output via GTX 1660.
The only way out this is state is to shutdown, disconnect the battery and CMOS battery for a few seconds.
After that the built-in dispaly starts working fine again (and after sleep, hybernated, shutdown) if I don’t makr any BIOS changes again.
I suspect that a wrong unlocked BIOS was flasded into the laptop and based on what BIOS shows, from a different Gigabyte Aero 15 line - from Classic 15 YA.
Also, I see BIOS shows ME Firmware SKU as Undetified and I have a suspecion that this is the cause of the problem with the built-in display/HD 630.
Here are a few photos from BIOS:
I have a flash programmer CH341A so I can reprogram the flash but I don’t know what I should reprogram it with as I understand I cannot just download the latest BIOS for the laptop model and write it into the flash.
Any help is appreciated!
