Can you test with another battery if available? Does Windows report the battery gauge and the battery gauge climbs over time? -

Remove all power. Remove the battery. Meter in resistance mode.
Measure the resistance across the mosfet pins to check if they are leaking.
source (1-2-3) & drain (5-6-7-8)
source (1-2-3) & gate (4)
gate (4) & drain (5-6-7-8)
Post each measurement. Start with checking the battery mosfet @ PQ103. If the resistance is low, then the mosfet may be defective.

My database shows that T470 = NM-A931 logic board. Can you confirm?

The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
If I let battery run out and say it has 3% Windows will... -
Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.

Hi guys.I bought Macbook Pro mid 2014 15 inch model which did not came with charger.
I got new charger but judging by the specs seems it is fake one.Sadly I live in Bosnia and genuine charger is rare to find.
what to do?Should I use the fake one?
Will it damage the macbook?... -
Hello friends,
I have this board not charging with charger, working fine on battery and type-C charger.
Here what if found: my IC chip miss VCC so i follow the line P_CHG_VCC_30 (0V) to P_CHG_VCC_R_30 (0v) and i get 20V A/D_DOCK_IN.
I loose my 20V on the PQ9009, i think it's dead because it's a P-Channel and I get 0V on gate and 20V on source and finally 0V on drain.
Am I right?

The Bauer power tool battery charger just has to many issues with the charger over heating because I several HERCULES Hercules battery chargers that are 3 amp charge and because they have gone on quite a few times over the years before they came out with the fan cooling battery charger I going to modify one so I can charge Bauer battery packs faster than the crape battery charger that they have
Here is how this modification is going to be done I taking a 1.5 amp hour battery enclosure and gutting it removing the battery cells and replacing some Ryobi 1.5 amp hour battery pack that...05-06-2023, 12:17 PM
