9 Ways to Extend Your Laptop’s Battery Life

| No comment
Dim your screen

              Most laptops come with the ability to dim your laptop screen.  Some even come with ways to modify CPU and cooling performance.  Cut them down to the lowest level.

Run of hard drive rather than CD/DVD

              As power consuming as hard drives are, CD and DVD drives are worse.  Even having one in the drive can be power consuming.

Cut down external devices

              USB devices (including your mouse) & WiFi drain down your laptop battery.  Remove or shut them down when not in use.  It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.

Keep the battery contacts clean

              Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol.  This keeps the transfer of power from your battery more efficient.

Hibernate not standby

              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.  Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.

Keep operating temperature down

              Your laptop operates more efficiently when it’s cooler.  Clean out your air vents with a cloth or keyboard cleaner.

Don’t multitask

              Do one thing at a time when you’re on battery.  Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3′s, set your mind to one thing only.  If you don’t you’ll only drain out your batteries before anything gets completed!

Add more RAM

              This will allow you to process more with the memory your laptop has, rather than relying on virtual memory.  Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.

Defrag regularly

              The faster your hard drive does its work – less demand you are going to put on the hard drive and your battery.  Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.
