My desk top (like most) ,awakens from sleep mode by pressing any key. Yesterday morning it just wouldn't have it. I tried the switch on the tower---still no response. I switched the tower off at the mains plug--and success; back on it came (after re-booting). Is this something anyone can encounter now and again??
don't think it is a good idea to leave it on sleep continually for 24/7..power off overnight if I were you...I had similar issues with PC which stopped when I did so...
Hi Murraymints -- On this particular occasion it had been awoken about 90 mins previously without a problem. It wasn't the first time used from overnight.
