Laptops
tend to lose their charm quickly when you’re constantly looking for the nearest
power outlet to charge up. How do you keep your battery going for as
long as possible? Here are 15 easy ways to do so.
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
battery.
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 battery.
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 - As 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:
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.
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.
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.
Bonus Tip #1: Turn
off the autosave function. MS-Word’s and
Excel’s autosave functions are great but because they keep saving regular
intervals, they work your hard driver harder than it may have to. If you plan
to do this, you may want to turn it back on as the battery runs low. While it
saves battery life in the beginning, you will want to make sure your work is
saved when your battery dies.
Bonus Tip #2: Lower
the graphics use. You can do this by changing the screen resolution and
shutting off fancy graphic drivers. Graphics cards (video cards) use as much or
more power today as hard disks – Thanks Andrew
