Screen Flickering

[Fama_H]

Screen flickering appears randomly when I am using my chromebook. In fact, it's wide black lines. It's not very frequent and will not cause a big deal, at least up till now. However, it really distracts me and makes me disappointed. I hope I can get a answer quickly. Finally, I feel sorry for my poor English. Thank you.

Thank you for posting on the HP Support Community.

• Have you made any hardware/software changes?

please perform a hard reset of the Chromebook. Sometimes, this will remove these lines since you are resetting the hardware.

A hard reboot can resolve many Chromebook startup issues. Follow these steps to perform a hard reboot:

1. Turn off the computer.

2. Disconnect all peripheral devices and remove all USB devices and media cards.

3. Disconnect the AC power adapter. If the Chromebook features a removable battery, remove the battery.

4. Press and hold the power button for at least 7 seconds.

5. Reconnect the AC power adapter.

   If you removed the battery, do not reconnect it at this time.

6. Turn on the computer.

 If that doesn't help, then you should restore your Chromebook. This will reinstall Chrome OS which will eliminate the issue if it is a software conflict.

Hope this helps! Keep me posted for further assistance.

I tried.  Since then the black lines seemed to disappear. However, today I saw it again. The methods didn't work. And it may be really difficult for me to check if there are hardware problems in China.
