Hi!

Please help. I have a big problem with my Acer swift 3, model SF314-56. When the charger is connected, the battery charging LED does not light up. When I try to turn on the computer, it won't turn on. When I disconnect the battery from the motherboard, the computer turns on fine. When I have the computer turned on and I connect the battery while it is running and then disconnect the charger, the computer works and doesn't turn off. I've tried resetting the battery but it doesn't do anything.

    Do a soft battery reset first like below at #3 if this doesn't work then do a Hard Reset by taking the back cover off, take the main battery out, disconnect the bios battery and take the removable ram out, leave all components disconnected for 15min and then reconnect everything and reboot, as this should reset the laptop completely and it should charge the battery.

    If the above doesn't work then your laptop has a faulty power stage that either a mosat, capacitor or a fuse is shorted/burned and is not allowing a charge and/or for the battery to charge and needs replacing and fixing by an experienced tech that has the appropriate experience and the proper tools to do this job. There is nothing that you can do and also there is nothing wrong with your battery (don't replace it) as a faulty or a battery that turns itself off will not work at all also.

    Why did you do this: "When I have the computer turned on and I connect the battery while it is running" That is asking for trouble! Your battery is probably bad blocking the Power supply from the adapter when booting. Get a new battery after 4 years:

  • Have you checked the battery wear with the hwinfo64 program? Can you tell me the bios version?
