My Aspire 3680 (crappy laptop PC) doesn't want to hold a charge anymore, with either battery. How do I determine if it's my laptop, my batteries, or my charger? (I have a VOM and know how to use it).

How can I recharge my nearly-completely-drained car battery so that it will work long enough to drive it to get crushed? I'm hoping to avoid buying a brand new battery just to have it crushed. [more inside]

The "battery not charging" light on my dash went on; the mechanic told me I need a new alternator. Now the "battery not charging" light has turned itself off again. Does this mean my battery is, in fact, charging? [more inside]

I'm sure somebody else who's travelling over Thanksgiving could also benefit from this knowledge. I brought my cell phone with me on my five-day trip to my parents' place, but of course I forgot the charger. The question I ask is: 'tis nobler to leave the phone on continuously and hope the battery pulls through, or is it a better idea to turn the phone off every night and turn it on only at the point in the day when I plan to use it? Does powering off and on drain more battery power than idling / the cell phone equivalent of "sleep"? FWIW, I have a relatively new Nokia 6682, and the battery is currently showing a full charge but I suspect it's lying, as I think it's been at least 24 hours since I charged it (that said, this battery's done five days unplugged before).
