My girlfriend is looking to buy a laptop as a desktop replacement... but I had a few question first. Can you run a laptop 24/7 like a desktop (plugged in, of course)? Are there issues with heat? She'll occasionally be taking it to work, but if she left it on at home all weekend, would it cause problems? She's specifically considering a Dell Inspiron 8200 (P4-M 1.6). Thanks in advance for any advice/help?
