Teach you how to calibration laptop battery

Now laptops particularly widespread , whether outdoors or indoors to be used , especially in the outdoors, laptop thanks to battery-powered . Over time, we will find the Sony VGP-BPS5A battery life did not start so long , and before you can use 3 hours , now only battery life 2 and a half hours . How is this going ?

• life Shorter , not the battery itself problem of

For time less than 1 year of battery , life shorter , more often than not because the
Apple A1189 battery normal aging , but because the battery in many times charge and discharge the process , the laptop BIOS system battery had a miscarriage of justice. have been battery There some power , but the BIOS has the illusion that power is exhausted, so that books forced shutdown. If this battery life has shrunk situation , first of all do not just conclude that the Thinkpad x300 battery quality problems , and can use the " battery calibration "This simple and easy way to make the remaining capacity into full play.



The battery correction method is more than one , there are usually three ways: using BIOS, the battery calibration procedures, artificial means battery calibration and the use of third-party batteries calibration software. Here mainly to talk about the first two correction methods .
Tips : do not recommend using third-party battery calibration software. As for the reason , you first need to install third-party software, not the first two is simple ; Second , in fact, behind the correction the principle is similar, third-party software and not too many a unique places , but also a potential security risk. Therefore, by the first two methods to be completed the PowerBook G4 Battery calibration the case of is not recommended to use third-party software.

• Standard calibration method: using books BIOS in the battery calibration function

Many brands of notebook computers in the BIOS which are integrated battery calibration procedures , the general in English statement is called "Battery Calibration", or " battery proof . " Directly into the notebook BIOS Can be done Dell Inspiron 1520 Battery calibration operation , here to Asus notebook , for example, simple talk about how , of other books the operation similar to .
step 1: boot, appears boot screen , press 【 F2 】 to enter BIOS menu; through the left and right arrow keys, choose to enter Power menu.
step 2: enter the Power menu , you can see the "Start Battery Calibration" option ( Figure 1) , select it and press the Enter key to execute.
step 3: when the screen turns blue , and English prompted to the laptop 's power adapter plug in to charge the HP Pavilion dv7 Battery . Such as the battery is full , the screen and prompts the user to disconnect the power adapter ( Figure 2). after the notebook start Continued of battery discharge until the battery consumption Jing.
step 4: This process will take some time , such as the Dell Inspiron 1501 battery runs out automatic shutdown after , and then connect the power adapter to charge the battery , but do not boot. Such as fully charged (charging indicator goes out ), the battery calibration process is completed.
Edit Comment: This operation is more official the XPS M1210 battery calibration way to , the whole process takes about 4-5 hours , more time-consuming. If you find that your laptop battery did not take long , like a few months , life as the original , and the books BIOS with this feature , I suggest to implement it.

• Cottage correction method : Let books boot the natural discharge

Some notebooks, the BIOS in the how to find can not find the Lenovo Thinkpad t60 Battery calibration options. Is this the notebook to can not the battery correct it? In actual fact, we can "unauthorized" battery calibration method for its operation . The reason is called the "cottage "because it is not official way , but through our manual some of settings, so that books in the normal work discharge until the automatic shutdown.
Tips : "unauthorized" battery calibration methodology
On the surface , the battery calibration is the process of the GK479 battery charging and discharging , but it is not intended as we might expect to activate the battery , because to books batteries are lithium batteries , there is no activation issues. The discharge real purpose of is to the computer re- recognize the battery capacity. Therefore, to try to call on the clean, so that books work in smaller power, such correction the effect of to do.
Here are some manual the battery correct necessary to steps .
step 1: books in the operating system (in Windows XP for example) , go to " Power Options . " The " power scheme " select " always open " , and " Turn off monitor ", " Turn off hard disks "is set to the shortest possible time , and the system standby to be set to " never " ( Figure 3).
step 2: In the " Power Options "and" alarm " , deselect all the alert options (Figure 4), the goal is to the battery is completely depleted until shut down .
step 3: set complete , close all applications , turn off the WIFI, unplug the power adapter , battery power supply as 60wh apple A1184 Adapter. Do not do anything until the battery runs out after the automatic shutdown . the process Compared with the estimated length of may take several hours. discharge After , even the power adapter , the battery is full , then completed a battery calibration .
Edit Comment: After correction , try the PA3451U-1BRS battery life time is increased, if not obvious , in accordance with the above method again once , but is not recommended frequently . If the battery has been long used time, and do the battery calibration , the effect was not obvious , it may be the battery itself, the life of natural aging . In addition, if laptop battery life a normal , we do not recommend the battery .
