How should I protect my laptop monitor and component so that they will last longer? Is it okay to use a laptop more than 3 hours?
you can use your laptop for as long as you want this wont affect it what so ever, it will stay the same temp no matter what.
Of course it's OK to use a laptop for more than 3 hours. Who said that it wasn't? Does it say that in your user manual? I think not. Apparently all of the superstitious laptop owners come on Yahoo! Answers at 9PM (GMT-5). I use my work laptop constantly and my personal laptop almost as much. Neither has had any problems related to nearly constant use. All you have to do is make sure that you don't block the ventilation holes in the side or bottom of the laptop so that it doesn't overheat, and you're good to go. Basically, don't lay a laptop on a soft object like a bed or a couch or you'll risk thermal damage to the laptop. As long as you keep it on a hard surface like a table top, your laptop will last for years.
