lenovo laptop battery Instructions

First, note that the details of the using.

In the actual use of the process, many of the details have not been noted, has affected the life of your lenovo battery. For example when the AC-powered laptop at the state shutdown, waiting for the power indicator light and the bottom of the screen all the lights off after the exchange with the plug pulled (not later than 5 seconds). After the lights go out because the power supply board are still working, this time will begin to pull the plug on the battery, thereby accelerating the battery more quickly fell to the charging power to set the starting value, thereby reducing the battery charge with the cycle, affecting the battery's life.

In addition, when using AC power supply, the adapter plug the input plug and output plug (unload) the correct sequence of operations is: First the AC adapter's output plug into the power jack plug, and then plug into the input plug power outlet; and should be removed when the input should first unplug the plug, then pull the plug then the output. This will prevent the adapter has been damaged in a no-load state.

Second, in-use maintenance and storage.

1, the battery charge times by their limited life span, so there are places in which AC power, they should make full use of AC power to minimize the number of thinkpad x40 battery charging to extend battery life;

2, when the electricity is 3% to 5%, it is timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine can be in any state, side by side rechargeable battery also will not hurt ;

3, power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge the thinkpad x40 battery, otherwise they will reduce the charge to increase with cycle number of charge cycles and shorten the battery life;

4, if the battery a long time (several months) do not, remove the saved backup from the machine; if the battery a long time unused, it should be set to 30% of electricity consumption to 50% in storage; Do not put the battery temperature and cold environment, the battery performance will be temporarily reduced. Should be at standby mode to save battery life and storage of the state placed in places of lower temperature for the thinkpad x40 battery, the best temperature range is about 10 ~ 20 degrees Celsius.

Third, on the activation of the battery deal.

Just purchased a new Thinkpad batteries to activate processing, ie 100% charge and discharge, in fact, a random Thinkpad help to say "re-engineering of your thinkpad x41 battery every month, that your battery is 3% or less, which will increase your battery capacity ", is intended to adjust the battery management chip and charge control chips in the normal value of each register. Statistics chip power consumption by recording the discharge curve (voltage, current, time) can calculate the sample thinkpad x41 battery power, and if the chip has not been opportunity to once again read out the full curve, calculated results can also be allowed.Therefore, the need to calibrate the deep charge-discharge.
