Bauhn 1500cm Actios
SOURCE: Turns itself on and off
The unit has a timer function and a Sleep timer function. Have you ensured both of these are not on? If thy are off I would guess that either a button is bad and inducting a control signal to the controller or the controller itself is bad and just randomly is setting on and off times at random.

If the service shops didn't charge people $200 to fix this I would not post.. But since they do - here's the $8 fix.
If you are electronically inclined, replace the three 1000uf 16v
electrolytic capacitors in the power supply board located above the
power switch. They are likely bulging out at the top and failed. They
are the three in a row at the top - center of the board, located
between the two black heat sinks. Make sure you get caps rated for 105c
degrees! I recommend replacing them with 1000uf 25v caps. 35v caps will
work but might be a tight fit as they are larger diameter.
Should cost you about $8 for the parts shipped. You can get them from
partsexpress or digikey or any good local electronics store. Your local
radio shack may have them but they won'y be 105c and thus may not last
long.
Not handy, ask around, there is usually some electronic tweaker guy around that will install them for a few bucks.
This has solved the turns on / then off problem every time in the 3 I've done.

It seems to me the first place I'd check is the power supply because it shuts off. There might be a short or the power jack might be loose.
Acer laptops are notorious for overheating which could be your problem as well. A couple months ago, in my computer shop, I had a computer do the exact same but it would shut off a half an hour after boot up. I offered to apply thermal paste on the chips inside the laptop, but he didn't feel like putting money into it, so he sold it.
If your tech savvy, you can try and take apart the laptop and look to see if the jack is loose and apply thermal paste on all the exposed chips. Just Google your laptop manufacture and model and you should be able to get a tear down guide. (I looked for 5 minutes and couldn't find anything, sorry) I like iFixit for guides and you maybe able to find more information about your problem there. Try message boards/forums there might be someone helpful there. If all else fails take your laptop to a local "small business" computer repair shop. Don't use the big retail stores like Best Buy/GeekSquad because they are horrible at diagnosing problems (they think everything is caused by a virus) and rip people off.
I hope I helped you get more information about your problem. If you have questions, just comment below. Good luck solving your computer problem!

Replace lamp in tv as this symptom shows existing lamp is near to end of its working hours life span and need to be replaced.
Lamp replacement procedure is easy and would be written in user manual.
Buy Sony original lamp for good picture in tv.
