[woodline]

Hello together,

from today I have pa problem with my keyboard.

The Background light is not working anymore and the keys are sometimes not working so some letters are missing by writing. At second try the key are often wrorking.

I already had contact wih customer support but 

so i tried to do this :

Please do this:
1. Switch off the device, disconnect all devices that are connected including the power supply and then press the power button for 30 seconds.
2. Reconnect the power supply, then hold down the "Windows key" and "V", now switch on the device and keep the keys pressed until something appears on the screen. Then the buttons can be released.
3. Switch off the device again. Then switch on and immediately press the "ESC" key several times. In the "Start up menu" please press the "F10" key. Here in the BIOS please press the "F9" key. Confirm the window with "load setup defaults" to "yes". Then press the "F10" key and confirm the window with "yes".

at the beginning it worked fine again. But not for long time

Also restart with the on Button is helpul for some time,.

I also tried to deinstall the driver for the keyboard but no change.
