I noticed that when I close the lid, without the bil connector connected, the standby light goes off.Leave a comment:

Hey
After the arrival of the PD 100W source, I tested the board again and it worked well... I had already repaired the board, changed a capacitor and was unable to turn it on because my power source was lower than the minimum required (96W), as reported by [USER="295753"]mon2[/USER] .
Thank you very much for the tip and support in repairing this complex logic board.
PS. The Desktop GaN USB Type C PD Charger is unreliable, but it powered the board without a battery.
Thanks to everyone who helpedmon2Leave a comment:

Okay, you're right.
I'll look for another one of more reliable quality.
ThanksLeave a comment:

Very good, thank you very much for the tips.
I have already ordered a 100W PD charger (total 240W), according to the manufacturer.

ppbus_g3h 12.65V
discharged battery. The power supply I am using is 65W.
Q7065 (G) CHGR_BGATE = 12.65V - PPVBAT_G3H_CHGR_R (S) 12.65V - PPVBAT_G3H_CONN = 0V.
I will order another new battery to install.Leave a comment:

Could anyone get me the block diagram of the power sequence for this 820-001700 board?
There is no such page in my schematic.
The board has changed the nature of the problem a little... Now it turns on the initial sources and turns them off.
I suppose there is a short in a secondary source S3, S0...
With the source connected, it produces 20V and the current varies from 0 A to 0.5 A in approximately 10s
By pressing the power button, the fans rotate and the current goes up to 2.5 A and returns to 0 ALast edited by Sergio Kub; 06-21-2024, 07:01 PM.Leave a comment:

I was unable to repair it and returned it to the customer.

I will try to turn on the power and simultaneously inject 3V into the output of the U7800 and observe the electrical currentLeave a comment:

The board does not turn on
PP3V3_S5 and PP1V8_S5 missing
I put the board in the computer and checked that the Power key was working.
If I keep the power key pressed for about 5s the current goes to 0A on the external source.
I didn't find a short in these sources.
I observe strong heating in the U9300 and U 9200 by around 55ºC.
I don't have much experience with this 820-01700 board, but it's strangeLeave a comment:
