If you are using hibernation mode it causes all kinds of problems, not working, corrupting window files so you are forced to do a fresh install. The reason is windows needs to be properly shut down, other wise it will become unstable to the point you won't be able to access files. I strongly reommend to disable this function or at the very least make a backup recovery disc.

it needs service, and service manuals are hard to find on anything by the likes of ACER. this projector worked for 12 long years, did you own it 12 or bought a bad projector, no history told as I can buy dead projectors all day long. and hard nut problems even hacking done. Acer X1110 data projector Standard throw projector.. did you know most projectors have serious grade protective devices inside??? (tamper and overheating are 2) did you read owners manual page 32 yet, errors. LED codes.? there are 4 LED, and all 4 matter, projector turned (ON) (not one =1) also in pairs glowing and also if blinking or not, so read page 32 it tells all that. my guess is overheat failures, even cold, due fan slow or packed in lint after 12 years of use and no service done,. https://manualzz.com/doc/49497108/acer-x1110-user-manual some have dust filtler a shop first cleans is out first, and check fan RPM with and LED tachometer. this is all SOP.

That button can be set using the utility on your programs list

It maybe that you accidentally turned it off or set it to do some other task.

I would try starting up and go straight into the BIOS. Set up your system and reboot.
