Hi all,
Is the correct battery for the 6920g 10.8v or 11.1v? I have both variants here, and both charge/work.

Hi
Acer A515-43
LA-H801P
Fail: Does not charge battery, has low voltaje on connector.
Laptop didn't want to turn on, only charge led blinked.
I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...
I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.
Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know... -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
Hi Everyone,
I have brought you a mistery item
This laptop have come with some strange faults.
1. CMOS battery was flat 0v
Symptoms:
- After using the laptop and shutting down and removing the AC adapter for at least 1 minute, the laptop never turned on until EC reset (either shorting RTC or removing battery and long pressing power button)
Amp drawing was stuck at 0.005 milliamps.
- Laptop cannot really be turned off because it autostarts about 5 sec-1 or 2 minute. (lid sw is not the problem)
After inverstigation RTCD1 diode had a low value... -
This was a no power initially. Thanks to your help, I discovered it was the first mosfet, so I replaced. Now, the device will power up only if the battery is NOT connected. As soon as I connect the battery, it shuts off. If I connected the battery while the device is off, it simply will not respond to the power button. I replaced the battery, and while I suppose the new battery could be faulty, I'm assuming it is not. I'm having the same behavior with the new battery. I measure .2v at the charging coil. Manually applying power to the + and - at the battery header, there is no charging happening....

Hello guys,
Laptop have been dropped, broken screen and battery had no voltage on connector.
I replaced the screen and it's ok, but still no voltage on battery connector, 16.91V on cells, which is fine for 4cells battery.
I ordered a brand new battery from Acer, same thing, no voltage on it's connector.
Is this a MB issue?
I did some measurement on the bq24780s, but since there is no voltage on battery i'm not sure it's any help?
Thank for reading.
