Teach you how to extend battery life notebook
Laptop battery life a long time, they are often dissatisfied with the charge, or even show damage and must therefore be in use when the attention of some tips: Whether you use the notebook lithium or nickel-hydrogen power, to the extent possible, after the exhaustion of basic electricity charge (electricity Less than 5 per cent), which is to avoid the best way memory effect. In fact, lithium-ion battery has some memory effect, only smaller than many nickel-metal hydride batteries only. But it should be noted that, charging, to avoid long time, the general control within 12 hours.
Battery life is not by the length of time, but by the number of charging and discharging to the decision. If the battery always with a notebook and not to take down, then shut down machines and even remove the AC power, the hp battery will not like the imagination, as has been the state when fully charged. Notebook computer batteries due to the battery in the integrated control circuit, so even if the computer is shut down when power is power. As one connected to AC power, will begin charging the battery, when turned on or off the power, the battery will be repeated charge and discharge, the impact on battery life.
To this end, the use of an external AC power when the best disconnect the battery, or long battery life in a fever state of its impact. If the batteries do not have long to charge and discharge at least 12 months time, to ensure that its activity. In the custody of the battery when there is a need to pay attention to the problem. Currently, the vast majority of notebook used by the lithium-ion Pavilion DV4000 battery long time if not in use, they often excessive discharge of the phenomenon, may no longer be able to charge. In order to prevent excessive discharge, in the semi-charged state will save in a cool dry place, and then every six months, and then charge their electricity to half of the state.
In addition, the impact on battery life of factors including the use of the temperature (in the proposed use of the following 30 ℃), battery storage temperature and battery suffered shock size. In the use of a battery after a period of time will be aging, specific performance is the resistance of larger, the time in charge at both ends of voltage rise faster, thus easily be charging control circuit judge to have the full capacity and is also a decrease of . Presario V2000 battery correction is to deal with the aging batteries effective way, there will be only a small number of laptop batteries correction software. If your laptop does not discharge the special software, you can follow the steps below:
● will disable the screen saver;
● in the Windows power management will use the power programme is set to “always open”;
● alarm in the tab will be “electricity shortage warning” is set to 10 percent, operation is set to “no operation”;
● “serious electricity shortage warning” is set to 3 percent, operating as “pending”;
● transferred to a maximum brightness of the screen;
● confirm all the windows closed, and save all the data before work;
● confirm batteries in more than 80 percent, to unplug the power and all external equipment.
After the discharge notebook will automatically shut down after the power plug to recharge laptops, this process can be repeated two or three times, the goal is to continue on the current ThinkPad R40 battery discharge, which discharge status in our day-to-day use is not possible Achieve, the effect of the discharge and those dedicated software basically the same.
