computer randomly goes into sleep mode while typing

I have a new Acer Aspire 4820T running windows 7 home premium. I have a problem with the computer randomly going into sleep mode. This seems to happen especially while I am using remote desktop although not entirely. The computer is not getting hot and I have turned off sleep mode entirely or at least  think I have.

I can be typing at the time so am actually using the keyboard. Incidentally this is the second computer it is happening to as I sent the first back thinking it was a hardware problem.

Any help would be appreciated

dear Mike, 
try this out of the box solution. It worked for me:

Dear mn2rgorillaz,


     I'm a computer repair technician and suddenly one day I started having the same problem, 9-12-2011 in fact.  I tried everything, reloading the computer, flashing the bios, changing all settings to never sleep, and none of them worked.  I was still having the same problem with my computer going to sleep in the middle of my typing, all random of course, i could type a paragraph or only a letter, and suddenly wham it would go to sleep.  I was very frustrated, so I sat down for an hour and thought about anything that had happened that day to try and figure out what might have happend.  I didn't want to think the worst (bad motherboard).  It took me a bit but it finally hit me.  I had bought this pretty new braclet that day, one of those magnetic ones that are supposed to help with arthritis and carpol tunnel syndrom. 

      As a computer tech i felt very foolish because as any of us in the field will tell you computers + magnet = trouble.  I didn't think anything of it when I bought it and had already forgotten I was wearing it.  Bingo, took it off about 10 minutes ago and I've been typing like a mad woman every since.  No problems what so ever.  Just thought I would throw this out there in case you might just be wearing said kind of braclet. 


GREAT Leah I think you nailed it!!! 

My acer as3810T begun with this mysterious behavior also and I also updated BIOS, updated office, ran several system optimizers, etc. nothing helped. 

Now that you mentioned the magnets. I hurt my hand and my mother recommended to put some small magnets on the the base of my thumb what should have the effect of acupuncture without needles. 

i am typing now with only one hand (the one with no magnets) and sure enough the PC doesn't sleep in the middle of the sentence!! 

Great shot! That's what I call thinking out of the box!! I would never get that one alone. thank you very much for sharing your insight with us.

cheers from Brazil
