LapBook Plus - no start up

I have LapBook Plus (LapB P Q 256G19110908) from February and it worked well with Ubuntu. But from 3 days it’s impossible to start the OS and impossible to see the screen and the keyboard doesn’t work. I plug in my TV with HDMI cable and I can see the screen and I can enter in the bios but the keyboard is not working so I cannot check if the BIOS is well… Do you have a solution?
Many thanks in advance

Hi,

Hi,

I opened the laptop and plugged of the battery for one hour. After plugged in again, it was be possible to enter normally into BIOS setup.

It was also possible to reinstall Ubuntu but impossible to boot in the disk. It’s not recognize. At startup I have the screen below. Any idea?
