can you set an alarm to warm you of low battery?
Just got my new MacBook Pro. Love it, no problems. However, it's replacing an old 12" Powerbook with exhausted battery. I kept that machine plugged in at all times, so I never had to remember to plug in when the battery charge was running low. My windows netbook automatically prompts me to plug in when charge gets below 15%.
Is there some way to set such an alarm on the Mac? I don't want to have to watch the percentage meter in the toolbar, I just want an alarm to go off. Thanks!
