Hi there and welcome
Can you remove the power cable from the Asus then hold the power button in for 60 seconds then release.
Connect the charger again, turn it on and tell me please if you still have the issue.
Disconnect the tablet from the Keyboard, then connect it again, while it is on, does it then respond?
When did the problem start?
Which version of windows do you have installed?
Thanks, ***** ***** to do a system restore please.
To do this, close all programs.
right click on the windows start button, bottom left, and click on Control Panel
