I have a fairly new laptop, an Acer Aspire a315-51-38G5

It runs on battery and at about 50% is suddenly shuts off, then I plug it back in for like 5-10 minutes, and it recharges back up to 50%. It  goes from 0 mWh to over 10 000 in  a few minutes.

Then it runs and extra hour this way, going all the way down to it’s capacity.

I’ve reformatted Windows 10, so that’s not the issue.

So basically it goes from 100% battery to 50%, then drops to zero…then charge it for 5 minutes and back to 50% and can run the rest of the battery as if there were no interruptions…

The new battery had 37 000 mWh when new, but now it only has 18 000, but still can get 2 hours out of it at least , by doing that little 5 minutes charge trick.

I ordered a new battery, but I think it might be the battery controlling hardware? 

I did drop the laptop on hard marble floor a while back. Would that bread the battery or the controller? It fell on it’s side, broke a couple usb ports, but apart from that all fine...

    Hi,
    Have you installed the new battery? or it hasn't arrived yet, I suspect the motherboard might have got damaged as you have mentioned that you have broken USB ports, anyway, give this a try and see whether it helps, go to Device manager, expand batteries, highlight and right click Microsoft ACPI compliant control method battery, select Properties, go to Driver tab and uninstall the driver, reboot and let Windows install the driver.

    I have the same model of laptop, it s nearly two years old and the battery behaves exactly the same. I guess it's because the batteries wear out over time, so now they have only half of their "designed capacity".
