Whether you own a Windows or Mac OS laptop, following these basic tips will make your battery last much longer between charges.
DIM THE SCREEN
By far the biggest power drain on most laptops is the screen or to be more specific, the screen’s backlight.
Simply reducing the screen brightness can add 30 minutes or more to your battery life. If your laptop allows it, use the keys or buttons near the keyboard to adjust the brightness. Typically, you’ll hold the Fn key and press one of the function keys in the top row, or one of the cursor keys labeled with a sun symbol.
AVOID USING CD OR DVD
If you store a copy of data you need on a CD/DVD, copy it to your laptop’s hard drive or a thumb drive before traveling. Optical drives consume large amounts of power to spin up CDs and DVDs. Try to avoid applications that keep your hard drive or optical drive spinning. Need to play music? Try to use your handheld MP3 player, rather than playing songs on your computer. Playing songs on your computer will keep the hard drive working which uses energy.
RUN LESS OF PROGRAMS
If you’re the sort who has 10 or even 20 tabs open in your web browser, you’ll benefit from longer battery life by reducing those tabs. The same goes for running lots of applications at the same time.
When you run lots of programs, or have lots of photos open, you’ll use up all the free system memory. Anything extra has to be ‘paged’ to the hard disk, which as we’ve said, is a mechanical device in many laptops.
SHUT DOWN OR HIBERNATE
Shut down or hibernate your laptop rather than using standby, if you plan on not using it for a while. Standby continues to drain energy to keep your laptop ready to go when you open the cover.
AVOID SOFT SURFACE
Avoid placing your laptop on a pillow, blanket, or other soft surface that can heat up.
DISABLE WI-FI AND BLUETOOTH
If you’re not using them, disable Wi-Fi and Bluetooth. Both radios can use a fair amount of power, so it makes sense to turn them off when you’re on battery power. Most laptops have a switch or key combination to disable Wi-Fi.
KEEP THE BATTERY FRESH
Batteries leak power if they aren’t used fairly soon after charging. If you use your “full” battery 2 weeks after you last charged it, you may discover it is empty.
Facebook has activated its safety check feature after a suicide attack killed 32 people in the north-eastern Nigerian city of Yola.
The social networking site had been criticised for activating the feature for the attack in Paris on Friday but not for the attack in Beirut the day before.
Before the Paris attack, the feature was only used in natural disasters.
The safety check allows people to inform their contacts they are safe.
During emergencies mobile phone networks often collapse under the stress of everyone using their phones at the same time – so this is one way to help solve that by informing possibly hundreds of friends in one go.
The system was first used earlier this year during the Nepal earthquake.
Facebook boss Mark Zuckerberg announced the Yola Safety Check in a Facebook post but added “unfortunately, these kinds of events are all too common, so I won’t post about all of them.”
This is the third attack this year in Yola.
The suicide bomber targeted a busy vegetable market late on Tuesday as stall holders were closing up.
Boko Haram militants started attacks in Nigeria in 2009 in an attempt to create an Islamic state.

“A loss of human life anywhere is a tragedy, and we’re committed to doing our part to help people in more of these situations,” Mr Zuckerberg added.
One Yola resident who used the feature, Maulud Usman, told the BBC he feels Mr Zuckerberg had taken on the previous criticism.
“I was one of those that criticised him when he activated the safety check in Paris despite the fact that Boko Haram has been bombing us in north eastern Nigeria for years, killing thousands of people, yet Facebook didn’t deem it fit to activate the safety check.”
“I’m happy he listened to our cries”.
BlackBerry has launched its first smartphone running the Android operating system.
It is a new approach for the company which has struggled to attract customers to its own operating system, BB10.
BlackBerry said its new device, Priv, was designed to offer customers improved security over rival Android handsets.
“Coming with a device that tries to address security on Android is a good idea, but may have been better three years ago,” said Francisco Jeronimo, research director for industry analysts IDC.
“It will be difficult to regain clients who have already moved to other handsets, and it’s quite an expensive device.

Chinese tech giant Huawei has unveiled two prototype removable lithium-ion batteries that can recharge in minutes, using a bespoke charger.
The lower capacity battery charged by 68% in two minutes – but is not big enough to run a smartphone for long.
The higher capacity one charged by 48% in five minutes and could provide up to 10 hours of talk time, the firm said.
Current battery life is a significant limiting factor in the performance of portable devices.
Many tech firms and entrepreneurs are researching the issue.
In March, Samsung announced that the batteries in its new Galaxy S6 handsets could power up to four hours of usage after a 10-minute charge.
Israeli start-up Storedot unveiled a fast-charging device at the beginning of the year which it hopes will eventually be able to charge any smartphone battery in under one minute.
Scientists are also researching alternative battery materials to the traditional lithium-ion such as aluminium and graphene.
Huawei says it used heteroatoms – atoms which are not carbon or hydrogen – which the firm claims can increase charging speeds without affecting the battery’s overall lifespan.
“Everyone in the world – consumers and all the manufacturers – would benefit from some unforeseen breakthrough in battery chemistry technology,” Microsoft president Rick Osterloh said.
Nothing is quite as joy killing as realizing the only new messages in your inbox are automated emails from LinkedIn. LinkedIn knows this, and it’s begun addressing the issue to prevent its website from becoming the ultimate bane of every email user’s existence. The solution is a new internal software tool LinkedIn is calling Air Traffic Controller. Building on its successful initiative earlier this year to chop the amount of emails it sends users in half, LinkedIn is now developing the system to send only emails and notifications that it feels are relevant to how you use the service.
LinkedIn’s goal is to annoy users as little as possible. Its new tool will now monitor how often you check LinkedIn, use your preferences and habits to figure out when and on which device to best reach you, and keep track of what features you rely on most. That way LinkedIn will contact you only with messages and notifications that are relevant — not something you’ll instantaneously delete upon reading the company’s name in the subject line. LinkedIn says it will improve the system over time, but that users should see an “immediate improvement” to communications they receive from the company starting today.
