Hello,
Several months ago I changed the operating system on my [B]TrekStore SurfBook E11B[/B] to Ubuntu.
Before that, I used this laptop quite rarely and I don't remember how the battery worked on Windows.
Under Ubuntu, at first the battery worked, but couldn't last more than 20 minutes.
For a few days (under Ubuntu) I noticed that the battery was not working at all: without a cable, the notebook could not start.
I tried to check if Ubuntu sees the battery, but the test failed: Ubuntu does not see the battery:
[CODE]pavel@PASADENA:~$ upower -e
/org/freedesktop/UPower/devices/line_power_ADP1...

Thanks.
It worked ... although after reset BIOS (i.e. holding power-on during 15 sec) the new power-on (just after BIOS reset) was slow to start - I had to wait a few minutes after powering on until the screen was on.
I was already on the verge of giving up thinking that in my case it didn't work.

Hello,
Well ... TrekStor no longer exist.
Does anyone know of a TrekStor related resource or where can I find schematics?
I changed a single setting in the BIOS and since that this notebook does nothing upon power-on.​
Thanks.
Sincerely,
Pavel.
