Hello,

I did some reading. Is there a way to repair a laptop like this if there is no bios dump.

I have already tested various bios dumps from other users. There are 3 behaviors.

Behavior 1:
The "i" from ThinkPad and the power button flash 3x. Everything stays black and the device switches off.

Behavior 2:
Only beep melody which means Error 0284.

Behavior 3:
After starting, the keyboard lights up and the fans rotate for a short moment. Afterwards the device restarts, then the same behavior. Then there...

I have the original bios. but I think he didn't save it correctly. But it's worth a try.​

Serial Number: PF190PVB...

Hello!
I received a Lenovo P52 20M9. When it starts it just makes a series of beeps. According to diagnostics, this is error 0284. I have already tested other bios with Ch341 but without success. Or the power LED lights up 3 times and nothing happens, or the beep sequence comes with 0284.
