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,.

some have dust filtler
a shop first cleans is out first, and check fan RPM with and LED tachometer.
this is all SOP.

There a few issues that can cause this, the obvious one is that the battery has failed internally, but it can also be a charging software issue. Try this. Unplug from the mains supply. Remove the battery. Leave the computer for 2 hours. Press and hold the power button for a full 2 minutes. Replace the battery, plug back in, count to 10 and power it back up.
Has the motherboard battery ever been changed? They are critical to the health of the motherboard and the machine in general.
Most laptops have a tiny lamp that illuminated the Caps Lock and Num buttons.
These are used to remind the typist they are locked and for error messages when the motherboard won't start properly.
Carpets hold billions of tiny insects and dirt particles that thrive on what regular vacuum cleaners can't remove. The only way to rid your carpet of these pests is expert and professional carpet cleaning.
