It's most likely the nvidia graphics chip. Bad connection caused by getting really hot and cooling over and over. Many times this issue manifests itself with actual video related issues or no post. Other times though, things like wireless and detection of the optical drive. Nvidia chip needs to be reflowed. Do it (or get it done) right or it won't be long before it happens again. Also, replace that heat pad on that chip with a copper (or least aluminum) shim with some artic silver. Assure good contact and keep your cooling policy set to active on battery and ac. This is probably beyond the scope of most, but if you're skilled enough to remove the motherboard yourself you may be able to find someone who can do it for you. And you'll probably save at least 50% on labor since they don't have to do the disassembly/assembly.

If it is a SATA drive, check the manual of the motherboard for SATA options/configuration in BIOS.
If it is an IDE drive, I suspect a bad configuration.
Set the jumper in CS (cable select) mode. You may connect it to the primary (end) or to the secondary (middle) connector of the IDE cable. Be sure there is no other drive on the same cable. Turn on your computer and verify if there is any changes in BIOS.
If the drive is not seen in BIOS the cable or the unit may be damaged or incompatible with your computer.
If the drive is seen in BIOS turn the computer off.
Now, you may add any other drive (if any) on the remaining connector on the same cable as it follows :
- set the jumper as Master or Cable Select if you connect the drive to the primary connector (end), or
- set the jumper as Slave or Cable Select if you connect the drive to the secondary connector (middle).

I use a program called "locksmith" which is included on a "commander disk" that I have.

Perfectly normal. It depends on the internal timing of the GPU and the OS version.

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.

Start there first before re-installing the program that sets it.
That is on one of the cds that should have come with it and can be installed by itself.

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