Method 1:

Laptop battery, especially Li-ion battery is idle for too long, or just maintenance, and it is the charge curve and discharge curves are generated by a certain offset, need to put a real end-filled cycle of steps to remedy the restoration of several of its charge-discharge curve, we also known as the battery self-learning process.

1. Settings (which is most relevant to be able to fix the thinkpad t40 battery to the best state of the most important step. Please Do not need to pay attention ) a to open My Computer, Control Panel è è è Power Options power scheme shown in Figure 1 using the thinkpad t40 battery of the full-time parameters chosen item has never b the alarm two options hooks removed, the purpose is that when the battery down to a few percent of the time for the program does not respond to the corresponding operation, so that the laptop battery power put a real end, so that the battery itself, the minimum power to amend its synchronization with the curve of 0%

2. Charge-discharge: As you set up after the full release on the End of the principles according to the lenovo battery charge and discharge, back and forth two or three times, you can offset the curve of the battery repair over. Note: When must let the battery charge is full, it is best The approach is to charge off a few hours or one night, and then unplug the power discharge, until the computer shuts down automatically out. This back and forth at least two cycles

Method 2:

Lenovo Battery use and charging the instability will cause the thinkpad t41 battery capacity decline, this decline is not due to aging caused by, so the right can be calibrated to make this part of the loss of the capacity of recovery. Therefore, the battery calibration on a regular basis is very necessary thing, such as the January-February time.

Such as Compaq and IBM laptop’s own power management in BIOS or a program provides a battery calibration feature, so use two brands of friends can according to the prompts. For those who do not provide this feature the brand’s users can follow my following steps:

1. The screen saver is set to “None” .

2. In the Windows Power Management power scheme will be set to “always open”, and will be following the closure of all equipment related to the menu is set to “never”.

3. In the alert tab will be “insufficient power warning” is set to 10%, the operation is set to “refrain from any action”; will be “a serious power shortage alert,” set to 3%, operating as a “standby”.

4. The screen brightness to the maximum.

5. Confirmed that closed all the windows, and save all the data from previous work .

6. Confirmed that over 80% battery charge after the unplug the power and all external devices, this time, if the screen automatically reduces brightness, then place it hit the brightest.

OK, you can go to sleep, the discharge after the notebook will automatically shut down after the power plug to recharge laptop, pay attention to, etc. must be fully charged and then boot, then the power before the program back to the calibration settings.

The aim is to continuous low current discharge batteries(lenovo N100 battery,Lenovo N200 battery), which discharge status in our daily use is unlikely to be achieved, as the normal state of inevitable that we will carry out all kinds of make up and down changes in current operations.
