While the print may read between two and two and a half hours, the in reality, it could be a great deal less. There’s nothing more  frustrating than being part-way through a task when the battery indicator flashes and there’s no mains electricity connection in sight. If your battery lifetime appears to be significantly less believe. It’s due to a number of different factors .Obviously, the more tasks that you’re attempting to carry out on your laptop. The more resources your system is going to use.

Furthermore, there are several best practice techniques you can employ which will  combine to help extend the life span of your battery.  When you’re using your laptop from a mains power supply you should always try to remove the laptop battery if you’re not charging constantly which in turn will result in a reduction of its life span. It will be capable of a finite number of charging cycles so only connect it to your laptop when absolutely necessary. In addition, remember that you should run battery down as low as you can before charging it up each time. If you ‘re working with a new battery pack then it’ll need to be fully charged and discharged before it works to capacity.

Top Tips

1. Graphic-intensive applications, such as games, or even watching DVD movies on your laptop, will place significant strain on your battery. Avoid these pursuits until you’re able to hook it back up to a mains power supply.

2. Your laptop will sound a warning, when your battery starts running low on power. You can adjust the point at which the alarm sounds using the settings under the Alarms tab in Power Options. There are two settings you can activate. Low battery alarm and critical battery alarm. Once you’ve selected your options you can choose what type of alarm action is used, such as an audible alarm and/or a message.

3. Some laptops come with settings or a built-in utility to change the display brightness. The LCD screen is one of the biggest users of battery power so any reductions you can make here will help extend battery life.

4. You can use Hardware Profiles to disable specific devices that may not be required for a particular session. For example, you may not need your CD/DVD drive, so you can create a profile to exclude it and save power.

5. Another way of ensuring maximum performance from your battery is to disconnect all unnecessary peripherals from your laptop. For example, if there are USB devices that you’re not using then unplug them.

6. Take a look at the Advanced Tab of Power Options and you can choose what action takes place when you close the lid of your laptop or when you press the power button.

7. If you’re storing your battery and not using it, try and keep at 40% charge rather than running it down.

8. Don’t keep too many program windows open at any one time. Close those that aren’t required and you won’t use as much CPU and memory power.

9. Add more RAM to your system. If possible, because this will reduce the amount of strain that’s placed on the hard disk.

When you’re not using your laptop and want to power it down without turning it off completely. You have two options at your disposal Standby and  Hibernate.  Hibernation works by creating an image on your hard drive and memorizing the files, folders and applications that are open at the time you choose to Hibernate. When you switch your PC on again your system will boot upward go back to its original state with those same items on screen. It depends on how much data has been saved by your hard disk, but you generally find that starting your PC from hibernation is much quicker than performing a normal boot.

When it comes to choosing between the two main power saving options. Standby is probably better if you’re going to be leaving your PC unattended for a couple of hours or so. This will send your system into a reduced power mode with the benefit of a fast resume time for when you want to start working again. If you wish to put a hold on your work activity for a longer period of time, say overnight for example, then Hibernate is probably going to be your best bet
