If
your laptop seems to run out of juice far too quickly, try these nine
power-stretching tips to help make the battery last longer
Battery
technology has improved considerably over the last few years, but few laptops
can still last a full working day between recharges.
There
are some steps you can take to stretch out battery life for as long as possible
when you’re away from a power socket, and while this list of tips won’t have a
dramatic effect, they will still make a noticeable difference.
Check
out the video above to find out more.
Tip 1: Reduce
the screen brightness
The
bright lights behind a laptop screen are one of the biggest power drains, so
keep the brightness low when running on battery alone.
Laptops
have keyboard shortcuts to adjust screen brightness, usually accessed by
pressing the Fn key, so learn them and use them.
Tip 2: Reduce
the screen time-out
Set
the screen to turn itself off after one minute or so of inactivity. In Windows
7 and Windows 8, search for Power options from the Start menu or Start screen,
then select Choose when to turn off the display in the dialog box that opens.
Go to On battery - Turn off the display and select 1 minute or 2 minutes.
Tip 3: Set the
standby time
Leaving
a laptop running when it isn’t being used also wastes battery power, so set it
to go to sleep after a short period of inactivity - it will wake up as soon as
you press a key. In the same Power options dialog box opened in Tip 2, change
the Put the computer sleep option to around five minutes - anything shorter
risks the laptop sleeping while you’re trying to use it.
Tip 4: Turn off
wi-fi and Bluetooth
Unless
you’re connected to a wireless network when you’re out and about, turn off your
laptop’s wi-fi wireless network connection - it’s another power waster.
There
may be a keyboard shortcut for this, or you can right-click the wi-fi icon in
the Windows Notification Area at the bottom left of the screen (switch to
Desktop mode in Windows 8 for this) and select Open Network and Sharing Center.
When
the dialog box opens, click Change adapter settings on the left, then
right-click the icon for Wireless Network Connection and select Disable.
You
can disable Bluetooth in the same way — and reverse these steps to re-enable
wireless connectivity.
Tip 5: Close
unused applications
Just
because Windows can run several applications at the same time doesn’t mean you should.
Keeping several applications open at once places an extra burden on the
laptop’s processor and uses up valuable memory.
Windows
will start to use hard disk space as ‘virtual’ memory when the laptop’s actual
memory is full, and this too uses extra power. Close any applications and web
browser tabs that aren’t being used, and consider a memory upgrade if your
laptop only has 2GB RAM - this will make it feel a bit faster, too.
Find
out how much RAM your computer has by heading to Control Panel –System and
Security – View amount of RAM and processor speed.
Tip 6: Keep cool
Laptops
usually have no problem keeping cool when they’re working hard, but having fans
spinning to suck fresh air through the case take their toll on battery life. So
always ensure your laptop is well ventilated when running on battery power and
that any vents on its sides and underside aren’t obstructed.
Keeping
these vents free from accumulated dust also helps ensure the laptop’s cooling
system runs efficiently, which in turn improves battery life.
Tip 7: Unplug
peripherals
It
goes without saying that not using an unplugged laptop’s built-in CD or DVD
drive when running on battery power will extend battery life, but so will unplugging
any other peripherals.
Anything
plugged into a USB port, for example, uses a small amount of power, so use the
trackpad when you’re on the move rather than plugging in a mouse. Disconnect
USB flash drives as soon as you’ve finished using them, too.
Tip 8: Carry the
mains adapter with you
One
sure-fire way to make your laptop last longer when you’re away from home or
work is to plug it into a power socket. It’s surprising how many businesses
will let you do this if you ask, and some trains and planes also have mains
sockets just for this purpose.
This
does mean carrying the power adapter with you when you go out, but the bit of
extra weight could be well worth it if you’re likely to be away for longer than
your battery might last.
Tip 9: Check
your battery’s age
Finally,
if your laptop battery doesn’t seem to last as long as it used to, it could be
that it’s nearing the end of its life. All rechargeable batteries have a finite
lifespan and this is reduced each time it’s recharged.
If
your laptop is more than a couple of years old and you frequently use it away
from mains power, then the battery could be on the way out as the constant
recharges and drains take their toll. A new replacement will work wonder.
