dell laptop battery

Your laptop battery power supply time getting shorter, in fact, the reason this is not the battery as long as a small correction, it may as durable as the original stainless cemetery strong sleeping Shorter life, not the problem of battery itself

For less than 1 year battery life shorter, more often than not, because the battery normal aging process, but because of the DELL Latitude D620 battery medion  in a number of the charge and discharge, the BIOS of the notebook system generates a false alarm on battery power. It has some batteries, but the BIOS has the illusion that power is exhausted, so that books forced shutdown. If there is such a battery life of the case in the first place not only shrink the conclusion that the battery quality problems and getting the "battery calibration" using this simple way to exploit fully the remaining capacity. Like "Battery Calibration"

Dell Inspiron 1520 battery Calibration are several ways it is usually three ways: with the BIOS battery in the calibration set manually and using third-party batteries, battery calibration software. Talking mainly about the first two methods correction.

Tips: To not recommend using third-party battery calibration software. As for the reason you need to install software from third-party is not the first two simple, second, in fact, the principle behind the correction is similar, a unique third-party software and not too many places, but also a potential security problem. Therefore, two methods should be made through the front of the housing of the Dell GD761 battery calibration is not recommended to use third-party software.

Standard Calibration: using books in the BIOS battery calibration
Many brands of notebook computers in the BIOS battery calibration is integrated, the general statement in the English language "Battery Calibration", or "proof-battery." Directly into the notebook BIOS battery calibration can be done to be here to talk notebooks such as Asus, for example, how simple, similar to the functioning of the other books.

Step 1: Start, boot screen appears, press F2 to enter the BIOS menu of the left and right arrow keys, you choose to come to power.

Step 2: Enter the Power menu, you can see the "Start Battery Calibration" option (Figure 1), select it and press the Enter key to run.

Step 3: when the screen turns blue, and English, asked to put in the laptop's power adapter to charge the battery. As the battery is full, the screen and asks the user to disconnect the power supply. Continued after the start of the Dell Studio 1737 battery is discharged until the battery consumption Jing

Step 4: This process will take some time, such as automatic shut-off after the battery is empty, and then plug the power adapter to charge the batteries, but not boot. How fully charged (charging light goes out), the battery calibration is complete.

This process will take several official battery calibration approach, the whole process takes about 4-5 hours, more time. If you find that your Dell Inspiron 640m battery does not last long as a few months, life as the original finding, and the BIOS using this feature books, I suggest to implement it.
