Battery Meter

Background (top)

Sometimes the Lithium Ion battery will not fully charge even with the correct charger attached. The battery meter may report only 5 or 10% charge and not increase from there. This is fairly common with many LI devices. Thankfully, resetting the battery often fixes the problem.

A reset requires the battery to be fully discharged. This must be done using the BOSS it. Discharging the battery using the OS isn’t enough however. Instead it must be fully discharged using the BIOS.

Steps (top)

  1. Unplug the laptop
  2. Boot pressing the F2 button to get to the BIOS screen
  3. Take no action on the BIOS screen
  4. Let the battery fully discharge. The laptop will turn itself off
  5. Plug the charger back in
  6. Any time after two hours reboot the laptop

Expected Results (top)

This should result in a full charged battery. Our tests have shown reset batteries running well over 7 hours when idling and using Intel graphics. In real-world use, you should see the advertised battery life of 2-3 hours on dGPU and 4-5 on iGPU.
