touch and pen stopped working

should i redownload the drivers from the hp site? if i do do i have to delete or uninstall the ones on the system now?

 

will i have to open the system up and reconnect something; because the rotate button doesnot work either

 

i rebooted my pc and its fine now.

 

If it happen again download the pen driver again and uninstall the old one then install the new one and it work right off the bat. Had that problem befor also you may have to restart after uninstalling
