I would start by performing a power wash on the device. If its a school device the student would have to contact their tech department to do this because its a managed device that requires enrollment credentials.
Are you able to test the charger? does the light come on when you plug it in As far as the sticking keys here is a good video to watch on how to remove the keys. I would use a lens wipe to wipe the key and the area down before assembling. I show students all the time how to clean their keys. Bonus video I would use an L shaped pick like this to remove the keys because it will do less damage to the rubber nub in the middle. Once the nub is damaged and will not stay on the keyboard is damaged.
Well, that depends on how did the screen get busted? It could be damage to the board or it could be stuck in a boot loop. If the boot loop is the case then I would create a recovery flash drive using a windows machine. I hope this helps :) https://computers.tutsplus.com/tutorials...-to-create-a-chromebook-recovery-usb-drive-using-chrome-os--cms-28842 https://support.google.com/chromebook/an...
That model is older and the batteries by now are not as good. I would run a battery test in Crosh. https://www.howtogeek.com/309971/how-to-check-your-chromebooks-battery-health/ If the battery health is at 85% or below replace the battery. If the new battery doesn’t fix the issue than the issue is with the board. I work for a school and we have several of these devices. Most are parts now and the ones out are stubborn to go to a smaller screen due to battery issues or they got lucky, and have a good device.
No, it can only be used on windows or mac machines and the device is a school device so it’s managed. When Chromebooks are managed you cant enable developer mode which you can install Linux or a light version of windows.
After you have tried what @shiham said if that dosen’t work then open the device. unplug the battery and then plug it in. if the device doesn’t power up then while plugged in still do the wash sequence Esc, Refresh, and Power. If it does not come up after that the board is bad. If it does then proceed with the wash. After the machine comes up plug in the battery and test by closing the device and opening it again.
you need to take off the key without damaging it to see what interfering with it. It could be the spring housing is damaged or the nub under the keepboard is damaged and won’t allow the key to spring up.
