It keeps turning off and on by itself.

Hello, for some reasons my acer chromebook keeps turning off and on, thought it was the battery, plugged in the charger it still did the same thing.

I went on youtube, saw a video with similar problem, his solutions were:

Tightening the screws.

Did that worked for some weeks then it started again.

@oldturkey03 All and any screw you see in and out of the chromebook.

@maxwellimoh that sounds like an interesting fix ;-) Tell us how it "keeps turning off and on" exactly. What does it do? What does your Power LED show?

von

@oldturkey03 Whenever I turn it on, sometimes before I type in my password or even begin anything it turns off.

After it turns off, if I close the lead, few seconds or minutes later it turns back on, then later it turns back off.

My Power Led: At first I thought it was the battery but when I plugged in my charger it was charging normal.

But if I turn it ON even with the charger plugged in, it does the same it.

N.B this occured for complete two weeks untill I decided to disconnect the battery.

I JUST REMEMBERED:

I powerwashed my chromebook more than two times because of the issue.

@maxwellimoh for now I am not quite convinced that this is a power off situation. Start it up and try to run it through the startup. Once it turns off, darken the room and get a flashlight. Now shine the flashlight at an angle against the screen. See if you can still make out the desktop etc.

@oldturkey03 My solution is this:

I learnt that if I switch to guest mode it doesn't tun OFF or turn ON by it self, in fact it becomes more stable than a windows computer. I tried to find out how to make my own account same.

I learnt that Guest mode has only two apps which are Google Chrome and File manager.

And I realized that whenever I power wash my Chromebook, it automatically re-installs the previous apps making the issue to repeat it selves.

Since Guest mode has only two apps I had to start reducing the amount of apps I have by uninstalling some and living the most important ones.

I left only 3 important apps.

N.B I was also using my Chromebook to answer this question.

Seems like a power button issue that is being pressed at random. It is probably the chassis (did you ever drop it) pushing up against it, by tightening the screws it probably helped a bit by relieving the pressure on the power button. Can you check to see how the power button is (and if its damaged at all).
