Meanwhile, the laptop has the data transmission agreement end between battery and the computer, after the need of two or three times charged and discharged cycle, the percent of its real capacity can keep pace with the percent of content on the computer's screen. Cycle's steps: insert incomputer to discharge until the shutdown, and then recharge the notebook battery, charging time must be over 12 hours, to repeat the action of charging and discharging for three times.

The proper use of battery usually will be very crucial. Discharge can not fully take end, there are about 5 percent of electricity charging, we should not be spent replenishment.
