I have replaced the battery, but the same problem persists. When I remove the charger, Windows still shows that it is connected ot the charge, and the charger light remains on. We have to disconnect and reconnect the battery; only then will the charging symbol disappearComment

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.

by thesameHy 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.

by pc_okayHello 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?

by sam_sam_samThe 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 -
