Battery Tips
Here's a nifty trick i learned from my uncle about notebook batteries.
Problem:
Your batteries life cycle (500 charges/discharges) is becoming shorter and shorter.
Why:
You probably leave your battery charging for a long time, even if your battery is fully charged.
What happens:
Picture this: A barrel is left standing in a waterfall. Water flows in, until the barrel is full. But, the ignorant lazy person who left the barrel filling up with water decided that the barrel should just stay there. So what happens? That waterfall continues and continues to drop water on the barrel. Soon, the barrel is overflowing with water. All the water that was previously in the barrel is "leaking out".
So, in notebooks, whenever the battery is left there charging, it starts to charge, keeps charging until the battery is full, and then discharges all the excess power. Theres one cycle of power lost.
Solution:
Take the battery out whenever you decide to use AC power. This way, the battery isnt charging/discharging itself.
Hey by the way if i said anythin wrong here.....please, please correct me. i dont want to provide false info, i just want to spread the good word.

Raven1er,
In my opinion, your info is 100% correct!! I too beleive that removing the bat when on AC is the solution to save battery life. Unfortually i learnt the hard way and ended up having to buy a new battery to replace my old one which i did not adopt this technique of removing when on AC.

Thanks. My uncles IBM ran out of battery power in less than 5 months because of this. I should post this in the First time Users board. i'll do that.

If you want to know what WILL kill your battery, its the following: Discharging below 3%. Just dont do that,and you battery will last for its designed period.

This is along the lines of the age old question “Should I turn my computer off at night (I do)
What about the AC Adapter? Is there any perceivable advantage to unplugging the AC Power supply (With the green LED on) when the computer is shut down?
I would think that the only power being used is the miniscule current needed to power the LED, but what about heat?
On my Desktop I simply turn off the surge protector, but the Inspiron is plugged into another surge protector that is not easily accessible
I realize this is less-than a critical issue.
Cheers

Srry took so long to get back to you - your post got lost in the pile!
leaving it plugged in is fine. No difference between that and unplugged. Things only generate heat when they use power, so if its not carging and not running, no heat will be generated. The power used by the LED is miniscule.
Theres also no reason to turn of the power strip on your desktop either. In fact, I would recommend against it, so that your CMOS battery is constantly being charged.
