Maybe because of CH341.
The serial killer BIOS programmer.

Did you unsolder or read with clip?
Did you rewrite over it?

Bad solder joints, torn resistors.
It could be due to many things.

Black screen or no power
Remove battery a few seconds and try again

The power button blinks and there is no screen or fan

In the end, it turned out that the problem was not related to the BIOS at all, but to the motherboard itself.

When I first received the laptop for repair, I powered it on and saw that it was locked. I turned it off and began the unlocking process. However, after I first removed both chips, read their contents, and soldered them back onto the board, on the next power-on attempt the laptop would no longer display an image (power LED stays on for 5 seconds, off for 5 seconds).

This morning, out of curiosity, I decided to try again. I noticed that the CPU was heating up, so I thought everything was fine. However, on the second power-on – after connecting the display – the laptop again refused to start.

I decided to try one method: I placed the motherboard in the fridge for 15 minutes, then powered it on again. Amazingly, the laptop started, displayed an image, and I shut it down using the power button. When I tried to power it on again, it wouldn’t start.

Is there anything that can be done in this case?

I have exactly the same issue as you but I didn't try a fridge yet... 😀
I'm wondering if the on board memory chips are not loosing connection when soldering or desoldering a BIOS from the board... I think they are just on the other side of the board.

I'll give it a close look later on today but it's suspicious that it's not the first board is getting damaged because of removing BIOS chip process.

This is my original post and what I've tried.
