Hi Rickard,

I’d suggest that you update BIOS and chipset driver on your computer to check for issue resolution. Please enter your service tag # on the link below, then download the BIOS from BIOS section and Chipset from chipset section onto the system and install it.

Also, I would suggest you to connect an external USB keyboard on the system to check if issue reoccurs.

Hi again Dell-Ravi,

I followed your advise and at first it seemed like it helped, but unfortunately the problem has return. The key board stop function .....

As I wrote in the comment there are also a problem with the blue tooth mouse, that from time to time stop function. and I have to reinstall it. This happen several time a day.

Hi Dell - Ravi,

I followed your advise, regarding the Bios and the chipset, and at first it seemed as it helped. But today the problem has returned.
There are also problems with the blue tooth mouse, it sops working and I have to reinstall it.

Hi Rickard,

Please let us know if the external USB keyboard and mouse work fine on the system.

Also, please boot the system into the Safe mode (F8 during startup) to check if issue reoccurs.

Hi Ravi,

Unfortunately I have no external USB keyboard.

Since I'm not very in to the function of the computers I think I need more detailed guidance from you regarding how to start the system in safe mood.

PS
I have installed the Bios and the Shipset
