I just got a new Dell Inspiron 1150 laptop that I will use at work, and will rely on it to run some business software (would've got a desktop, but need a fairly portable platform). Any of you guys leave your laptops on for most of the day? I expect several periods in a day when I won't actually need to use the computer, but hate to think of numerous power up/power down cycles in a day, as well as just letting the thing run constantly. Am I worrying too much about it, or is there a consensus about whether it's best to leave it on or power down/up as needed? I'm likely to get a desktop eventually as funds permit, and let it run all day & use the laptop as backup. Thanks for opinions.
