Bios request for IdeaPad 5 Pro 16IAH7 - Type 82SK

[TheCod3r]

Hey folks,

Getting no post on a Lenovo IdeaPad 5 Pro 16IAH7. Thinking maybe corrupted BIOS but not sure. Does anyone have a working dump I can try?

Hello,

I need assisstance with a possible bios issue. Need to study bios editing further and not advanced enough yet.

Laptop turns on, charger light : blue and power on light: blue
fan spin. cpu warms up. keyboard backlight turn on. capslock and numlight not responding.
Black screen, no backlight and no hdmi output to external screen.

I suspect a bios issue or onboard memory.
A dump with Revelprog IS and software version v1.9.1 of the two bios chips are made and uploaded.

Not yet able to evaluate if one of those are corrupt.

Good evening,

i programmed the two files onto the bios chips.

The laptop restarted two times, caps lock and esc light light up and turned off, no image and same behaviour. Turn on, fan spin, cpu warm charge,power and power button continuous blue.

my guess, conclusion is the onboard memory.

thank you for your help and am enormous grateful.

best regards,

joeri
