Hello
The ASUS TP550LD has a sudden shutdown problem.
This device did not turn on before this problem was fixed by replacing the MOSFET PQ8802, but before the I / O heat given by another repairman, I checked the I / O bases completely, there is no problem, but now the device turns off sometimes after replacing the MOSFET or some Sometimes it turns off and on several times in a row.
Another problem with the device is that the battery charge light is always on, even when the battery is not connected.
I also tested the battery-related pins up to IC I.O and IC charging for ohmicity and connectivity, and had no problems with the resistors being the right amount.
The replaced MOSFET is exactly the same as the previous model.
The motherboard has no problems in terms of appearance and temperature.
The device is now on for 55 minutes and a full HD movie is playing, but the battery light is on while the battery is not connected at all.
Battery pins

ALL are present
Why is the charging light always on?
