Turn off laptop sleep mode?

As far as I know, every laptop where the battery capacity drops below 20% goes into power saving mode. How can I set the power saving mode so that it only starts at 5% or not at all? I would be very grateful for the solution.

But that's not good for the battery.

Well, you want it like this:

To do this, open the settings with the key combination [Windows] + [I].
In the "System" category, click on the "Power saving" tab.
Here you decide on the entry "Settings for energy saving mode" at the end of the page.
In the new window, check "Activate power saving mode automatically if the battery level drops below the following value".
With the slider below you can set in steps of five percent, from when the energy saving mode should be activated.

Thank you very much heizfeld! Why is it not good, I have often heard that it should not be good, but why?

Yes, because there's a risk that the battery will be completely drained until it is deeply discharged and this will shorten the service life. Is a difference whether you continue at 20% for 5 minutes or at 5%.
