Hi,


I have a Slimbook Hero, and recently I noticed that the already bad battery life is getting worse as time passes.

The battery in it is not even a year old (october 2024), but it already loses more than 10% in 10 minutes in some cases.

Usually lasts 1,5 hour per charge or less even in Quite mode.

I never dropped it, never used it in extreme temperatures and it only got to 0% 1-2 times.
The charge capacity left is 39Wh, with this rate I won't be able to use it unplugged in ~ a year I think.


Is there anything I can do?

Hi,
Try recalibrating the battery:

If the battery doesn't increase from 39 to around 60Wh, contact technical support here:

PS: The forum is more for configuration and user-to-user issues than for warranty support.
