Macbook: Battery health/life/longevity

[trouts]

Hi!
I have a Macbook OS X: Snow Leopard I bought last year in approx. September, and I'm getting real paranoid.

Right now its battery is at 50% and the monitor says that only 1 1/2 hour is remaining and that is really low isn't it?!

Yeah, I'm paranoid.

Plus, just an extra .. thing.
Sometimes it gets real hot, which usually is solved if I reboot it...

I'll try to reboot it now.
And I thank you for any input and yes
I am very paranoid!(I <3 my mac and I really want to keep it forever )

If the MacBook is hot, then the CPU is hot, if the CPU is hot, it is drawing a lot of power, if it draws a lot of power, than it means it has to calculate more, thus the CPU usage is higher.
You can use iStat Pro to monitor your CPU, temperatures and battery.
Have a look at Activity Monitor ( Applications / Utilities /) and select All Processes and sort by CPU to see what the culprit may be.
