I have an ex display acer chomebook 720 that isn't turning on.

1. when i plug the charger in (which def works) I see an orange light
2. when I press power to run onI get brief blue light and screen flicks on and then immediately turns off
3. same thing happens whether charging or not.
4. Have tried master reset to no avail.

any ideas..?

 
If it won't power on at all, no lights, internal sounds, etc., try Option 1. If, however, you get any lights on it or any internal sounds when you try to turn it on, try option 2.

Option 1...

NOTE: Yes, I know some batteries are not so easy to get to, on some devices. However, it should be removable/replaceable. Unless it is under warranty, then you should contact the manufacturer first.


Try the following and see if it will turn on...

1. Unplug your charger cord.
2. Remove the battery.
3. Press and hold the "Power" button for 30 seconds.
4. Now plug back in the power/charger cord.
5. Now put the battery back in.

If this doesn't help, then test the power cord to see if it is good. Either try your cord in another device, or try another devices cord in your laptop. You may also want to try charging it when the device is off, rather than on. If it works then, the cord is probably the issue.

Should that not be the problem, then check the battery to see if it needs replacing.


Option 2...

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

I am working on school Chromebooks and a bunch of them have the same problem. I already tried all the step you provided and they didn't work for me. The only way to fix them, as I have tested, is to replace the motherboard. I'm trying to find a less costing way of doing this but this thread is the only thing I have found on the internet that has similar problems to mine. I'm trying to figure out which part of the motherboard is screwing up and tracing it there, I will post if I find anything. But please still look. It would help.

UPDATE
I have found a solution. If you bend the motherboard just a little bit up or down on itself it fixes this. You have to keep it in this position however so my hypothesis is that something is not connecting right and needs some sodder or some kind of support in there. I have not yet found any permanent solution that doesn't involve you holding it however so please experiment with this.

Anybody having any luck with this? We are having this problem on a massive level with our Acer C740's. Probably 1-2 of these issues coming in a day. We haven't found a solution to this yet other than a mainboard and Acer can't give us a solution other than mainboards.
