Read the mention below note to increase your laptop battery life.
1. 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.
2. 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 you can
tolerate to squeeze out some extra battery juice.
3. Cut down on programs running in the background
Itunes, Desktop Search, etc. All these add to the CPU load and cut down
battery life. Shut down everything that isn't crucial when you're on
4. 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
5. 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.
6. Run off a hard drive rather than CD/DVD -
power consuming as hard drives are, CD and DVD drives are worse. Even
having one in the drive can be power consuming. They spin, taking
power, even when they?re not actively being used. Wherever possible,
try to run on virtual drives using programs like Alcohol 120%
rather than optical ones.
7. Keep the battery contacts clean:
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.
8. Take care of your battery
- Exercise the
Battery. Do not leave a charged battery dormant for long periods of
time. Once charged, you should at least use the battery at least once
every two to three weeks. Also, do not let a Li-On battery completely
discharge. (Discharing is only for older batteries with memory effects)
9. 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.
10. Keep operating temperature down
- Your laptop
operates more efficiently when it's cooler. Clean out your air vents
with a cloth or keyboard cleaner, or refer to some extra tips by
11. Set up and optimize your power options
- Go to
'Power Options' in your windows control panel and set it up so that
power usage is optimized (Select the 'max battery' for maximum effect).
12. 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!
13. Go easy on the PC demands
- The more you demand
from your PC. Passive activities like email and word processing consume
much less power than gaming or playing a DVD. If you've got a single
battery charge - pick your priorities wisely.
14. Get yourself a more efficient laptop
- Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries
. Picking up a newer more efficient laptop to replace an aging one is usually a quick fix.
15. Prevent the Memory Effect -
If you're using a
very old laptop, you'll want to prevent the 'memory effect' - Keep the
battery healthy by fully charging and then fully discharging it at least
once every two to three weeks. Exceptions to the rule are Li-Ion
batteries (which most laptops have) which do not
suffer from the memory effect.
