How to get the most out of laptop battery life of a Windows PC?

I'm a big fan of portability and battery life. I want to take the most out of a single recharge. Any tips to accomplish that?

Things on top of my mind:

• Voltage reduction (with RMClock, any better software?)
• Reduce brightness
• Turning off devices (any software to do that automatically?)

Solution 1:

Which laptop? Most laptops come with software which does a discharge-recharge cycle, that can increase battery performance. Check the website of the laptop manufacturer.

Other things :

• Disable wireless
• Do not use the CD/DVD Drive

These settings can be automatically set using Windows power manager.

Solution 2:

If you are using Windows Vista, the Vista Battery Saver program can help disable OS features that suck up processing energy that is less than ideal for a computer operating on a limited energy bar.

Solution 3:

Probably the biggest battery saver I've when trying to conserve power is to reduce brightness.

In addition - adjust your power settings.
