I have a 2-months-old Sony Vaio VPCCW21FX. It has a wired connection and I use it for downloading purposes generally. I leave it open most of the time but I really wonder if there's a break-point that the laptop starts to get harm. How long should I leave it open at maximum before I shut it down for a while for some rest? I need an answer like this:
You can leave your Vaio open for ... days, and then give it a rest for ... hours. Because ...
I've never had overheating problems with my Vaio within 2 months, but I don't know if I'll have in the long run. Does it shorten its lifespan to leave it open?
Mostly I leave it open for 3 days, and then I give it a rest since I don't want to do harm to it. Hibernation and sleeping modes are all off. I just turn the display off. Running programs are Firefox with DownThemAll! addon, uTorrent, MS Security Essentials and the routine system files. My OS is Win7 x64.
P.S.: I've seen some questions like "Leaving laptop plugged all the time" on SU. Since my question is totally different from them, please don't vote to delete.
