Make the most of your laptop battery

Get the most out of your laptop battery
laptops is that you don’t have to be connected to anything – so you are
free to do what you want, wherever you want. That is, until your
battery dies. Having decent battery life is one of the #1 concerns of
most laptop users, and so we thought we’d discuss how to make the most
of your battery in today’s article.
So you forgot your power cord on your way to an important meeting or
the coffee shop. We’ve all been there. There’s nothing you can do to
stop your battery drain, but you can do a lot to slow its inevitable
If you’ve got a laptop with a really old battery that drains in a few
minutes after a full charge, there’s not much you can do to make that
old thing last much longer—you’ll probably want to replace the battery
before you do anything else. For everybody else, these tips can help
you keep your battery working at peak efficiency.
Obviously we all know that using your laptop drains the battery
– but the #1 culprint, according to Microsoft
is your LCD panel – ie: your display. Other culprits are using
flash drives and USB mice.
What’s not so obvious are the speed your CPU is running at. Most modern
computers slow down and speed up depending on what you are doing at the
time. So when your computer is just sitting there doing nothing, the
CPU is slowed right down, to conserve power, and eventually your
computer will go into Sleep mode. Conversely, if you are doing
something intensive, like watching a DVD, your CPU is sped up, which in
turn drains more power.
Understanding how your battery is drained leads to the solutions for
maximising it. Let’s review.
your monitor brightness – how low can you go? The dimmer your
display, the longer your battery is going to last. Obviously, you also
need to see your screen, so
pick the balance that is right for you.
use external devices except when you have to – USB and
PC-Cards (aka PC-MCIA) use your battery to function, even when you
aren’t using them! Have an EVDO card or maybe a USB mouse?
Remove them if you can. Even a memory card reader in your PC-MCIA
slot uses power just by being in there. The effect varies based
on the type of device, but even a few minutes here and there (as you’ll
see) add up significantly.
- Do one
thing at a time – The more you are doing at the same time with
your PC, the more memory and CPU usage increases. Both of which
directly use up battery. Close any applications you aren’t using,
even the small ones. When doing some experimentation, I found it
more efficient to run a single application at a time, then close it and
open a new one when ready to move on. While your hard drive uses
the battery too, if you are doing anything ‘productive’ you are
probably hitting the drive on a regular (even if infrequent) basis
- Keep it
cool – the hotter your system, the more your battery life is
adversely affected over the long term. So keep those vents clear, and
try not to smother your laptop in cushions when using it.
- Shut down services you don’t need – do you really
need to be runing Windows Live Messenger, Yahoo Messenger, Google
Desktop Search, Quicktime and all your other utilities that are sitting
happily in your system tray? Close as many as you can – this will both
speed up your system, and maximise your battery life.
rather than Sleeping – when not using your laptop, there are a
couple of ways you can turn it off. You can completely power it off –
this saves the most battery life, but means that when you want to use
your laptop again, you need to wait for your computer to boot up and
log in to windows again, which is too long for most people. Or you can Sleep your computer – which puts it
into a dormant state, but when you want to use your laptop later, it
starts up almost instantly. This however, does mean that your battery
is being consumed, albeit slowly. Hibernate
is a useful middle ground – your battery usage is significantly
reduced, and it still boots up in a reasonable time.
There are other more technical options, such as tweaking your Power
Settings, however you should not try that unless you really know what
you are doing.
