Notepad Is Frozen

Customer-

My notepad has frozen. How do I reset it?

Dimmusacio-

Can you explain this a little more please? What exactly do you see on the screen?

Customer-

I did the most recent OS upgrade (after upgrade HP did not notify to restart), and went to an app. The screen is now locked at the app login - nothing is changing including the time and power - that was nearly 48 hours ago

Dimmusacio-

What version of windows, mac, or linux is on the notebook?

Customer-

good question.... it is a HP TouchPad with HP's WebOS. I do not know the latest version - it came out Thursday

Dimmusacio-

1. Hold top sleep button for 5 sec
2. Continue holding top sleep button AND hold bottom home button until the device turns off (maybe 10 sec)
3. reboot the device by holding top button until you see HP icon.
