The screen turns on late, the fans spin at high speed and the device turns off.
i tried to change the rt8816A as in post [url]https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/101205-hp-15-cb-dag75ambad0-rev-d[/url] a user fix the problem
The motherboard has two 8816a, PU9009 -> FBVDDQ_MEM to power graphic memory and PU9006 -> NVVDDS. I changed both. The issue is the same.
If i move to UMA works okhttps://The screen turns on late, th...high speed and

Re: Asus X541uv rev2 Always charging
P_CHG_BATPRESS#_10. 10k to ground
that line is connected to ec BAT_IN_OC# with a 10k resistor conected to ground.
The board with battery works perfect. Charge to 100% and stop charging at 100%. The only problem is without battery, so maybe i go to assemble the laptop couse with battery works ok.
Anyway, I would like to understand how the board detects the batteryLeave a comment:

Re: Asus X541uv rev2 Always charging
Hahaha i can share board's whatsapp number to meet boards dont want to charge
Mosfets are not in short, PQH8106 PQL8107, resistances are high. I just changed just in case.
What i found was some liquid damage, i just saw it on resistances rn2502, the signals are PM_RSMRST#_PCH and DPWROK_EC even a line was broken. Now is clean and the line is ok.
Now board turns on with and without battery, and charge battery ok but without battery charge battery too and the light is still always on.
What...Leave a comment:

Asus X541uv rev2 Always charging
Hi i have this board. With battery connected the laptop dont turn on.
Without battery, the board turn on but the board thinks always have the battery conneced. The charging light is on(without battery) and the mosfet are working trying to charge the battery (12v on coil, battery disconected). Even Windows says battery 100% when i open the battery icon.
I changed the bq but same behaviour
Can any help me?Last edited by tomimc; 01-25-2023, 11:44 AM. -
