        Thanks for the update. The cap you are using is not ideally rated for the surge / peak currents. There are better caps on the market and vary of course with price. Review the ESR value of the cap -> lower the ESR, the better the cap. Usually, the polymer style caps are selected for heavy current rails.

            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 Aspire V5-473P-5886 does not turn on with fully charged battery
            by mferna14
            Hi, today I am working on an ACER Aspire V5-473P-5886. The laptop turns on fine with AC power & in Windows 10 it shows the battery ICON & the charging percentage & the AC power plugged in, but as soon as I remove the DC-in jack power cord, it just turns off too. I charged the battery external 100% by shorting the Battery ( AP13B3K ) enable (Yellow Wire) to GND. Now battery Voltages shows 15.2 volts. Even check with a Known GOOD battery of the same kind & model, problem is still the same. I checked all the MOSEFT on the motherboard, they all seem to be ok. I think this yellow wire...

            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...
