There's a power switch? –  Dennis Williamson Jun 23 '10 at 20:20

Forever (provided it's not overheating or being shaken/thrown around while it's running).

All components have both a service life & a cycle life (how long they can run continuously & how many times you can start/stop them): No matter what you do you'll exhaust one before the other, so just use the machine however it best suits your needs.

Of course, many home users do in fact overheat their laptops on a routine basis, usually by operating them on soft surfaces. –  Miles Erickson Jun 23 '10 at 19:00

@Miles ... even those of us who know better are guilty of that occasionally. –  voretaq7 Jun 23 '10 at 19:05
    
@Miles: I've had my MacBook hit 204 on the CPU before. Running on a flat hard surface though. –  Josh K Jun 23 '10 at 19:37

You can keep it on for 6-7 days straight. Months even. Unless your wife gets angry that you've not showered or bathed for 6-7 days straight and haven't said anything more than a guttural growl when she tells you she wants to go out to dinner or do something requiring your attention. That might be detrimental to your health.

+1 for not showering. Quite the liberating feeling. The only thing that can beat it is bacon. –  Holocryptic Jun 23 '10 at 18:59
    
+1 to Holocryptic for Bacon. Mmmm, tasty tasty bacon... –  voretaq7 Jun 23 '10 at 19:00

+1 for putting those two close enough to think of bacon showers –  Jed Daniels Jun 23 '10 at 19:11

If I could upvote my own answer I would, simply for the epic comment thread it spawned. And a pancake recipe. –  Bart Silverstrim Jun 24 '10 at 0:10

Leave it on for couple of days and switch it off for an hour or so and then again you can restart it for 2 more days provided it's plugged in
