The convenience of the laptop is that it can work far from home and do not depend on the power source. For the duration of the laptop, the battery is answered without connecting to the network. Over time, the battery is wearing and reduces the opening time of the laptop offline.
A good charged battery runs up to 4 hours, depending on the programs used. If the time of operation of the laptop offline is significantly reduced, first of all it is necessary to check the battery status. You can estimate the battery wear using the AIDA program that replaced the Everest program. Install the program to the computer. Go to "Power" through the "Computer" section. In the "Battery Properties" parameters, information on the type of battery, its capacity and degree of worniness will be presented. The degree of wear is indicated as a percentage. High wear indicator suggests that it's time to replace the battery.Check the battery status can be tester or battery capacity indicator. The tester shows the battery information and checks the performance of the controller.
To extend the battery life, do not allow its full discharge. If you plan not to use a laptop for a long time to charge the battery by 40%, remove it and put it on the cool dry place.
