Hey Battery, are you OK? You've been saying 0% for 15 min now. (lemmy.world)

Running a Gigabyte U4UD, been having battery problems for months now, and the battery health only reports 50% capacity. Started playing Battlefront and got distracted and saw my battery looks like this now. Been doing this for 15 min, so either my battery is magical... or the Clevo design is flawed. Seeing how long she goes for on battery before it just dies.

I am not looking for tech support, just thought this would be funny.

There are 2 possibilities:

The battery is bad.

  • Replace it.

The battery is not calibrated.

  • Get it down to where the OS turns it off.
  • Turn it back on, and go into the BIOS and leave it on, unplugged. This will prevent the OS from turning the machine off so the battery can completely discharge.
  • Let the battery completely drain until the machine shuts off and won’t turn on again. If this step lasts several hours (like 3 or more hours), it’s likely this procedure will work. The longer it takes, the better the result will be. If it lasts less than 1 hour, this procedure won’t work.
  • Plug it in and leave it off.
  • Leave it plugged in until it completely charges. Probably around 8 hours to be safe.
  • After that, turn it on and check your battery health.
  • It should now work again if the battery itself isn’t bad.

Note: this procedure permanently reduces the capacity of the battery, so it should only be done as a last resort before just replacing the battery.

Sometimes it is enough to just drain the battery until OS shuts you down and after that let it charge to 100% with no interruptions (best not using the device at that time)

It may need multiple cycles

doing this about once a month should keep the "OS“ of the device (every device with a rechargeable lithium battery (phones, drills, cars, etc.)) calibrated with the actual SoC (state of charge) of the battery.
