Win7, correct charge and discharge curve:

Laptop battery, especially lithium ion battery idle for too long or just repaired, its charging curve and discharge curve are generated by a certain offset, need Correct the repair of the charge and discharge curve with a few cycles of performing a full fill.

1, as shown in FIG red frame, the time of the battery all the parameters selected to & ldquo; never & rdquo ;.

2, as shown in the red box as shown in the & rdquo; two options for low battery condition notification to remove the hook & ldquo ;, purpose when the power is down to a few percent when the program does not allow Perform the appropriate operation to let the battery charge out, so that the battery itself corrects its minimum charge to be synchronized with the curve 0%.

END

XP method, charge-discharge curve correction:

1, as shown in the red box, the battery of this time shown in the following All parameters are selected as “ never & rdquo;.

2, as shown in the red box as shown in the & rdquo; two options and a serious shortage of battery alarm alerts the hook all removed & ldquo ;, purpose when the power is down to a few percent When the program does not perform the corresponding operation, the battery's power is actually discharged, so that the battery itself corrects its minimum power to synchronize with the curve 0%.

4, the screen brightness is adjusted to the highest. Confirm that all windows are closed and all previous work data is saved. After confirming that the battery is charged more than 80%, unplug the power supply and all external devices. If the brightness of the screen is automatically lowered, please turn it on to the brightest, then the notebook battery will start to discharge. Note: After the discharge is finished, the notebook will automatically shut down, then plug in the power to let the notebook start charging. Be sure to wait until the battery is fully charged before turning it on, then restore the power scheme to the setting before calibration.

XP /Win7 method Third, the use BatteryMon software to recover:

1, BatteryMon download software from the Internet Download and unzip

2. As shown in the red box in the figure, double-click the file to enter the software page without any installation and registration procedures.

3, as shown in FIG red frame, into the page of the software, click on the & rdquo; option configuration & ldquo; button, the default configuration is provided in FIG. option on it.

4, the same, to explain the method according to a previously described method to set or two, the laptop power management setting is completed, then unplug the external power supply, battery operated only remaining work.

5, as shown in FIG red box, click on & rdquo; start & ldquo; button, laptop battery discharge.
