Acer C740 Chromebooks keep shutting down on students

We have had many Acer C740 brought into us because they keep shutting down on students while they are working. We have tried power washing them and that doesnt seem to solve the problem. Does anyone know why this is or what needs to be replaced to fix this. It is very frustrating. We have only had these devices for a little over a year too.
On some we notice too that its almost like the case is tweaking something as if they put pressure (hands resting while typing) near the sides of the mouse pad it shows down, BUT I dont see anything under the case that would do cause an issue. Any help would be VERY much appreciated!! I am not an expert by any means at fixing these devices and have only taught myself what I can from youtube!!!

Thanks in advance!

It is possible that the chromebook has an interlock button similar to the following:

This button locks the power on the motherboard if it is not pressed properly! This happens especially when the lowercase is misaligned! You should check if this button exists in chromebook!

I have not tried that, but what do we do after we press the power and refresh?? And can you please explain to me what that resets or what not. Again, I am learning here so I might have lots of questions!

Turn off the chrome book
Press and hold the refresh key and press the power button.
It will wipe all data , so make sure take a backup if you have any.
This is a simple troubleshoot to fix the issues

None of these fixes have helped us. We have some warranty left with CDW Safeware that we send them into, but they never tell me the resolution.

I still think in this notebook model, there should be some interlock interrupt button, which may not be properly pressed! This problem causes the notebook to shut down! Maybe some computer technician could check this out for you @deidrelm!

After my C710 was updated with v.65.0.3325.209, there was a browser pop-up with the error message that device did not shut down properly. Three months later the Chromebook would shut down instead of waking up from sleep mode. Problem was resolved with Chrome OS reinstall. Back up all personal files & ensure that browser is synchronized. Reinstall took 10 minutes.
