09. Saving battery life - six good tips

Having talked yesterday about having a second battery, there are of course a number of ways to increase amount of power you can get from a single battery charge.

1. Dim your screen
This is an obvious way to say power, since the backlight used to light the screen accounts for 2-3 watts of power.

2. Avoid multitasking
Minimise the number of programs running at the same time, including those running in the background. You can see how busy your CPU is by going to the Task Manager. Decrease the activity will increase the battery life.

3. Minimise the number of “devices” operating
USB devices such as the mouse can be a power drain. Switching off WiFi saves another 3 watts. Run from the hard drive, not from the CD/DVD drive.

4. Adjust the power settings
Use the one that maximised battery life. This will decrease performance slightly, but not enough to show with standard programmes such as word processing.

5. Lower screen resolution
This option decreases the call on the graphics computing. Although generally not recommended since the low resolution may be uncomfortable and counter productive, it is none-the-less an option.

6. Use “Hibernate” instead of “Standby”
Hibernate save far more power than going into Standby mode. Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does.
