      PR209 and PR211 is a voltage divider. check SWG1 on page 39 of the schematic, BI SW is the Battery In switch, it needs pressing in for the battery to be detected.It should press in when you screw the base cover back on .Those base screws around acer battery switches (and split holes on other acers) tend to come loose over time,stopping the laptop from switching on or the battery being detected .

            Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
            by Bowline
            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...

            Acer Aspire 5 A514-55 - won't power on, no charger LED, battery not flat - usual suspects?
            by DenK
            Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.
            1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down

            Acer Predator Helios 300 - will not power up if battery is CONNECTED
            by survivalbloke
            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....

            Acer TMX314-51 laptop battery problem
            by ahmarzo
            I have acer laptop tmx314-51 with part no 6050A3020501.
            The laptop is working fine on adapter and battery is also charging and when adapter is disconnected in on state the laptop gives backup on battery and gives good backup.
            But when laptop is powered on through battery only the laptop does not power on and there is 0 voltage on battery connector.
            I have not not tried another battery as it is not available locally could this be a battery problem.have checked discharging mosfet and there is no shorting to ground on any pin of battery connector.
            The schematic is not available...

            Acer A315-41G similar to AN515-42, AC OK Battery OK but not charging
            by titomno2
            Hi guys,
            I currently trying to figure out why the laptop of my friend did not charge.
            It is a Acer AN515-42 (Ryzen 5 2500U), I manage to make it works on AC and battery but no charging.
            At first it was not working on Battery, I discovered that PQ201 was knocked off and replace it => work on battery precharged on another computer.
            I also checked the small resistors between PQ312 and PQ201 and even if they are ugly values are OK.
            My issue, when I plug the charger computer off, it drains 0.25A during few seconds with amber light on (charging) then amber light blinks...
