Hi,
I was using Ubuntu alongside Windows 10 Home. All of a sudden, my battery won't charge above 59%. So I erased both SSD and HDD and installed Windows 10. But still grub rescue shows up and the battery still does not charge above 59%. Acer care centre shows battery life degraded due to longterm use but yesterday my battery was working fine. Please help. I do not know what to do.

    First try to reset the battery:
    Press and ho;d the power button for about ~15 sec., unplug the charger and leave it so for 20 to 30 min. After that plug the charger back in and power on. If that doesn`t help, calibrate your battery like in the link below:

    I tried doing it. Didn't work. I wouldn't worry if the battery capacity degraded over time. But suddenly this is happening. When the battery is at around 25%, the laptop dies. But again it doesn't charge above 59%.

  • Can you also provide the exact model? Example an515-51-75kz. Also, can you check battery wear with hwinfo64?

    @batmalin I tried uninstalling the driver as you said. It doesn't work.

    @egydiocoelho My Model is Acer Nitro 5 AN515-31-84D6. The wear as shown in HWiNFO64 is 55.7%.

    Also I noticed that battery starts to charge after I switch the laptop off and wait for 5 seconds and turn it back again. It charges from say 74% to 75% and the charging light starts blinking after sometime and the laptop stops charging. I did this till it reached 90% and then used the laptop on High Performance mode for around 3hrs and 10 mins before the battery died. The battery died when it was at 25%

    And there is another issue. I had installed Windows 10 andSand Ubuntu 1TB HDD for other storage. So I installed Windows 10 after formatting it but to my surprise the Grub rescue shows up. So I formatted both the drives again. But still the grub rescue shows up. 
  • I agree with colleague batmalin. Now, the voltage of the new battery should be the same as the old battery.

    Make sure, that the Windows Boot Manager is in the first place of the boot devices in the bios, and the grub rescue error will be gone.
