Using the battery

Battery is an expendable supply, so when you use it for a long time, the capacity/battery life is shortened. If the battery life is reduced to under half of the initial time, we recommend that you purchase a new battery to use.

Battery Warning

You will hear an alarm when the remaining battery charge is under 10%. Connect the power cable or turn off the computer and install a fully charged battery.

When the remaining battery charge is under 3%, the computer automatically saves current work and turns off. This may be different according to the settings in Control Panel > Performance and Maintenance > Power Options > Alarms tab.

It may happen that the battery does not charge when connected to the AC adapter and simultaneously using the computer on battery power. To protect the battery, the battery will not charge when the battery temperature is high (higher than 50ºC) and the battery will charge automatically when the battery temperature goes down below 50ºC.
