Herobook wont boot

And pc wont boot anyway

(in photo you see battery connected, but i have disconnected)

The software can’t work with 1.8 voltage IC without adapter.
Try to use Programmer V1.18 or NEOPROGRAMMER with 1.8v adapter. If that doesn’t work, you need to unsolder IC. The clip is not stable enough.

I noticed that the clip is of low quality, but I guess that wasn’t the problem. Besides, now I have no more answers from the chip, which I think did not like the 3.3 volts. I try to unsolder it, and maybe buy another one, since it costs very little. I also try the other programs you indicated to me. Thank you very much again. If I get results I update the post
