- Hibernate, Sleep, or Shut Down: Doesn’t matter much. Hibernate uses less power but restarts slower. Sleep uses more power but restarts faster. Shut Down: uses no power (because it’s OFF) but takes the longest to restart.
- My opinion (not “policy”): if you’re not going to use the laptop for more that 30 minutes or so, might as well shut it down. You’re less likely to forget about it and leave it Hibernating/Sleeping all night, which will end up using more power in the long run.
- This article suggests you discharge the battery completely – they suggest every day – and do not laptops plugged in for days at a time.
- Use a power strip and make sure it is turned off at the end of each day.
- Establish a regular and frequent backup procedure. This is the toughest part for most users, myself included. But, if your hard drive crashes, you don’t want to lose everything you – or your students – have been working on. Back up your saved files to a network folder, flash drive, or portable hard drive as frequently as possible.
