Problem description: The usage time with a fully charged battery appears too low; the battery runs out quickly.


Possible causes:


  • The battery is not initialised correctly.
  • The battery is frequently partially discharged.
  • Applications or processes are active that constantly require a lot of system performance (and therefore battery capacity).
  • The screen brightness is set very high.
  • The Windows energy mode is set in such a way that there is a high energy consumption (e.g. maximum performance).
  • Peripheral devices are connected that have a high power consumption.


Possible solutions:


  • Initialise the battery to restore full capacity: Fully charge the battery when it is switched off, discharge it to 0% and then fully charge it when it is switched off, repeat this process two to three times.
  • Check the system for active background processes and programmes and close them if necessary.
  • Reduce the screen brightness or use the automatic brightness adjustment function.
  • Set the Windows energy mode to a more economical one (‘Balanced’ (balance between performance and power consumption) or ‘Save energy’ (maximum energy saving)).
  • Disconnect peripheral devices that are not required or switch them off.
