          I've had this on HP Elitebooks so might be something worth investigating. There's an option in the BIOS to allow USB charging, even when powered down. Having this enabled usually flattens the battery overnight. Don't know if Acer has the same thing or not.

              Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
              by serious_electron
              Hello Everyone!

              I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.              ...

              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...

              Laptop Power Issue – Works on Battery, Fails on Adapter Load
              by yaya3gmax
              Dell laptop (E7440, uses the notorious CD3301B power controller + MEC5075 EC + BQ24715 charger IC)
              Symptoms:
              • Laptop works normally on a pre-charged battery.
              • Battery does not charge when adapter is connected.
              • Without battery:
                • Laptop powers on from DC adapter, passes CPU/RAM init checks, then cuts DC power abruptly.(seems to shutdown one of the mosfets in the charger path). Then the loop continues indefinitely
                • Speakers “pop” when power cut occurs indicating harsh sutdown.
                • If RAM is removed, the system shows RAM missing blink error code indefinitely without cutting DC power
              ...

              Acer Helios 500 (PH517-51) - unexpected reboots when laptop is warm (cold solder joint issue?)
              by Mirenia
              Hi everyone,

              got an Acer Helios 500 Laptop (PH517-51) for diagnosing with a strange issue:

              The laptop runs for a while (1-2 hours, sometimes less) and then suddenly shuts completely off, like someone pulled the power cord and restarts immediately after on its own.
              If this happened once, then the laptop only runs for a few minutes until restart.
              This happens regardless while staying in windows or uefi or in a linux environment.

              At first I thought of a normal overheating issue, but as I monitored temps with HWInfo64, nothing seems very hot.

              Acer Swift 3 SF314-42 not powering up
              by rutgerv
              Dear all,

              For a friend I'm trying to repair an Acer Swift 3 laptop (SF314-42). I'm not a professional, but have some experience (both as amateur and professional) in working with electronic design and repair of musical instruments.

              The issue with the Acer laptop is the following:
              It was bought new and used (not heavily) at home for about three years. After normal use, it was put to sleep, connected to charger and left over night (just like any other day). The next morning, the laptop would not wake up from sleep. Instead, when pressing the power button, the power...
