Ok so, I've got a 17" Aspire 5, when I put it under any sort of medium high load it just stops charging and show blinks the status LEDs which I suppose mean it get's in power safety mode.

I mostly suspect the latter but it seamingly started happening...

Hi, everyone.

I have this notebook that won't charge.
In Windows, the charger icon doesn't appear on the battery, but the charger turns on the notebook normally.

PU301:

Pin 5 (ACOK) - 5.97v

Pin 16 (REGN) - 6v

PQ308 has no gate voltage, so it doesn't drive PQ309 low

With the battery connected, its voltage goes the reverse way to the jack, having 14v and not 20v:

PQ301 e PQ302

Pinos 1,2,3 14v

Pino 4 5v

Pinos 5,6,7,8 com 14v...

Hi All,

Title says it all. We've got two Surface Book 3 model 1900 that require battery replacements for both the screen and the keyboard base. The battery that came out of those tablets, which definitely are the originals, isG3HTA044H.

And their batteries look physically different, they have two stacked vertically holes on both side of the battery pinout which mine does not have. Ifixit also states the surface book 3 uses a different battery than the...
