Would you have a 1uf capacitor from a donor board ? Other cap values may also be ok but 1uf appears to be proven to work.

By applying as shown by @smzlwan223, you will be creating a RC circuit that will trigger off the PP3V3_SUS line.

I have, I report the results.

Re: Need help with 820-00165

I did as @smzlwan223 said, but the problem remained the same.

Re: Need help with 820-00165

Can you post a clear and zoomed picture of your modification ?

Re: Need help with 820-00165

This is the best I can for now.

Re: Need help with 820-00165

Turning it on in safe mode most normally wakes up from sleep mode, does that mean anything?

Re: Need help with 820-00165

Looking at the picture you sent, I feel that your capacitor seems to be changed to the wrong capacity, remember must be changed into 1UF, so that can play the RT delay circuit.

Or You could try replacing the U8130 IC.

Re: Need help with 820-00165

Ok I report the results.

[goksi75]

Re: Need help with 820-00165

Replacing U8130 but the problem remained the same.

Re: Need help with 820-00165

Solved, replaced U6400 and now it works fine, thank you all for your help especially @smzlwan223.

There is no U6400 on this logic board.

Re: Need help with 820-00165

My mistake U6100.

You're too kind! Yesterday through Wechat and Goksi75, after the video to see the fault, it is very easy to find the problem, before the fault description, the maintenance of the problem caused by the wrong direction, in fact, the fault is caused by the internal program Error U6100 Rom. You can use a programmer to brush the factory BIOS ROM file.
