Don't think it has RTC battery. Its newer Intel i5 11th gen board. You mean get a new battery? Even if charging light changes to red and battery is charged? Sure, can order one.
Charging IC is BQ24728H. Attaching schematic shot.
VCC-19v
ACDET-2v
ACOK-no such a line, I guess its newer IC
REGN-3.1v...Leave a comment:

HP Pavilion 15S-FQ motherboard DA0P5HMB8J0 Rev J missing S5_ON
HP Pavilion 15S-FQ motherboard DA0P5HMB8J0 Rev J missing S5_ON.
Laptop gets 19V, light on, charges battery. No 3V and 5V because no S5_ON to enable them as far as I understand. Don't mind changing EC but Bios chip doesn't get 3V on pin 8 so how it will get firmware loaded?
No shorts anywhere
Please, any help anyone? -
Oops.Sorry. Looking at the wrong schematic

And there are no such lines on this board as:
I2C_TPAD_CONN_SCL

Tried 3 batteries, one of them new, all shows that. They work on other Macs and display all info correctly. So Mac fails to read.
Is U5200 faulty?...Leave a comment:
