You should check all secondary voltages, from pages 69-79.
If battery holds charge, PPBUS_G3H should not drop to 0V when USB meter restarts.
Also 3V3_G3H_RTC and PMIC LDOs must be stable.

Just a quick update, I am too sure if it's the battery or I was testing using a 87W charger , I went back to review the area of U7000 And I proceeded to replace R7061 , C7023 ,C7020 as well as U7000 , Now the device behavior while on the USB Amp Meter is staying without battery disconnected, but as soon as I connect the battery USB amp meter is going off and on. But it's not booting at all but the 20V is showing on the amp meter , I was not using the 96W charger Let me know anything please , Thank you.

I am not too sure I meant to type .
Post ohm resistance over C7020/23.
BTW, this board doesn't turn on with 87W; if no good battery connected.
