force power off by long pressing down power button and power on.

That’s bad. It is very seldom that that’s neccessary, as I was told here, myself. Please see the following for that:

[HowTo] reboot / turn off your frozen computer: REISUB/REISUO

Difficulty: ★★☆☆☆ This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means. So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here!
