First note that the details of the aid.
During the actual use of the procedure, Many details have not been noted, has affected the life of your battery lenovo. For example, when the laptop AC power the closure of state until the power light and the bottom of the screen all the lights after the exchange with the plug pulled (within 5 seconds). After the lights go out, because the power supply board are still in operation, this time starting to pull the plug on the battery, thereby accelerating the battery more quickly fell to the charging power to set the starting value, thus reducing battery with the cycle, affecting the battery life.
In addition, when using AC power, the AC adapter and jack plug output (discharge) the correct sequence of operations is as follows: Initial Release of the AC adapter the power jack and then plug into the socket outlet and inlet must be removed when the entry first disconnect the outlet, then pull the plug, then exit. This will prevent the adapter has been damaged a vacuum state.
Second, use maintenance and storage.
1, the charging time of battery by their limited lifespan, so there are places where food sector, they should make full use of alternating current to minimize the number of ThinkPad X40 battery charging to prolong battery life;
2, when electricity is 3% to 5%, it is appropriate to charge the battery, or the battery self-discharge phenomenon causes excessive discharge and damage to the battery, load the machine can be in any What state, side by side of the rechargeable battery will not be as bad;
3, power is not fully discharged before (Eg 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 life of the battery;
4, if the battery for some time (several months) are not, remove the saved backup of the machine, if the battery long time unused, it must be set 30% of electricity consumption to 50% in storage; Do not put the battery temperature and the cold environment, the performance of Battery will be temporarily reduced. Must be in standby mode to save battery power and storage of the state placed in places of lower temperature to ThinkPad X40 battery, the best temperature range is from about 10 to 20 degrees Celsius.
Third, activation of the agreement battery.
Just bought a new Thinkpad batteries to activate the treatment, ie 100% load and discharge, in fact, a Thinkpad using random words "Re-engineering of your ThinkPad X41 battery every month, that your battery is 3% or less, increase your "battery capacity, is intended to set the smart battery management chip and charge control of the normal value each register. Consumer Energy Statistics smart by recording the discharge curve (voltage, current, time) to calculate the sample ThinkPad X41 battery, and if the chip has not been the opportunity to read once again the solid curve, calculated results can also be allowed.Therefore, the need to calibrate the very high charge-discharge.
