#1 Asus GL553VD Laptop charging problem

Model : Asus GL553VD
Board id: GL553VD Rev 2.0

Laptop is charging for a few seconds and then stop. When unplug adapter and reconnect, it charging again for a few seconds and then stop again. Q8800, Q8801, Q8802, Q8803, Q8804 all are good. R8800 and R8809 are good. Charging IC is also good. BIOS flashing can't solve the problem. Need help.

Cześć,

Zmierz rezystancję do masy na L8800.

Zmierz rezystancję pomiędzy n.1-2 i n.12-13 U8800.

Zmierz napięcia na n.5, 8, 9, 16 i 17 U8800 z podłączoną baterią i zasilaczem.

Sprawdź czy R8812 ma 22Ω.

...as this is replacement (not genuine) battery - which in general are low quality(both cells and electronics), I would say that even it is showing Designed = Fully charged Capacity (wear 0% after 22 cycles), real capacity is different/lower and thats the reason charging stops (here plays its part firmware/electronics inside battery) or simply battery is faulty(typically one cell gets off the limits - charges/discharges faster than the rest). You can try to fully discharge the battery and try to charge from 0%, this sometimes helps...but only secure way to get real results is to do test/calibration on dedicated battery analyzer like NLBA etc. If you dont have such equipment, do your charging tests/diagnostics using GENUINE (....and tested/working) battery - else you are hunting ghosts.

Resistance to ground on the L8800 is about 3M.

U8800,
Resistance between n.1-2 is about 0.5 Ohm
Resistance between n.12-13 is about 0.6 Ohm
Pin 5 - 3.18V
Pin 8, 9 - 3.1V
Pin 16 - 6V
Pin 17 - 15.23V

Podstaw inną, 100% sprawną baterię bo ta może być uszkodzona jak napisał wof.
