Second, the " deep charge deep discharge " the basic approach

 

Battery calibration is an effective way to deal with the aging of the battery , in general, each brand will have a dedicated laptop battery calibration software. For example, IBM 's ThinkPad series have a dedicated discharge software , recommended for all users of IBM laptop use . However, the program needs to be repeated three times to get the best results , after downloading the software and perform the discharge , the system will prompt the production installation disk. Use the installation disk to boot PCDOS, tips unplug the AC power source , the software will automatically discharge discharge control . After all the notebook will automatically shut down, and then we can connect the AC power for charging, time control in 9 to 12 hours, repeated 2 to 3 times.

 

For activation of laptop batteries , we want to find the right key to discharge software. If your laptop unfortunately no dedicated discharge software , you can press the BIOS and turn off power management features in Windows , then do not run any programs in case the battery runs out, then with the power to charge to about 80% , after repeated several times is also tantamount to manually " deep charge deep discharge ." In fact , the purpose of this approach is to let the battery lasts a small current discharge , which discharge state in our daily use is unlikely to be achieved , the effect of discharging those dedicated basically the same software .
