Travelers’ Tips for Maximum Laptop Battery Life

Tweak Your Laptop For Max Battery Life With The Windows Key

Travelers, the Windows Mobility Center gives you instant access to the most important “tweaks” you can make to your laptop to get the most amount of use from it before the battery dies (aka “between chargings”). Just hit the “Windows key” + X.

Here are my Top 5 Tips for Travelers and laptops:

1) Dim your screen – Laptops come with the ability to dim your screen.  Reducing the brightness down to the lowest level you can tolerate is the best way to maximize your laptop’s battery life.

Use the sliders and drop-down arrows

2) Turn off the WiFi – This and Tip #1 are the “two biggies”. You will save a lot of power (battery charge) by simply only turning PwrOpts_iconon the “radio” when you are using wireless to connect to the Internet. Off when you’re not.
Also, most laptops have a key combination, button, or slider switch to turn the wireless radio on/off.

3) Run off a hard drive, or thumb drive, rather than a CD/DVD – As power consuming as hard drives are, CD and DVD drives are worse. Wherever possible, try to “play” your movies from files saved to disk, or run them on virtual drives using programs like PowerISO, Daemon tools, and Virtual CD.

4) Cut down on external devices – USB devices, such as a mouse, also put a drain on your laptop battery.  Consider removing them or shutting them down when on battery power.  When maximum battery life is important, charging other devices with your laptop is a “no no”. Take the time to charge your devices before you leave as well.

5) Cut down on programs running in the background – “Always ready” programs, like your IM client, iTunes, Desktop Search, etc., add to the CPU load and cut down battery life.  Shut down everything that isn’t crucial when you’re on battery.
Typically, this is done by right-clicking their icons in the System Tray (by the clock) and choosing “Exit” (or “Close”, or “Quit”).) Also, open Task Manager (Ctrl+Alt+Del) and select the Processes tab — click on those you recognize and know you won’t be needing, and then click “End Process”. Repeat as necessary. (If you do not recognize it, and do not know – leave it be.)

6) Go easy on the PC demands – The more you demand from your PC, the quicker you will drain the battery.  Relatively passive activities like editing a Word .doc consumes much less power than graphics-intensive activities like 3D gaming or playing a DVD movie.

7) Encrypt your hard drive – Have you encrypted your My Documents folder yet? Especially on your laptop? If you have an address book, tax info, a resume, business docs? More than half of all identity theft victims resulted from the physical theft of unencrypted laptops and thumb drives… which contained personally identifying data.

Today’s free download: The easiest way to seamlessly encrypt your whole hard drive, folders, or just selected files, is to install the free TrueCrypt. Use this and even if your laptop is stolen, the thief won’t be able to read your files.
Be sure to set a good password!

[Note: alternatively, you can click Start > Control Panel > Power Options]

Okay, so that was seven tips. Consider it Tech Paul’s Holiday Bonus Gift.
