Bought notebook computer friends may have such experience, just bought the notebook computer batteries electricity is very little, even can’t start the computer. Because the battery after a long time of storage battery, and has a natural process, have natural discharge discharge, this does not affect the capacity of the battery. First, you should charge the battery continuously to 12 hours to complete, and the cycle, discharge three times to fully awaken new battery. After such a program, the battery can be used normally. If a battery consecutively for 12 hours after three times cycle after cycle or not, the battery charging still can’t use need to be replaced. General rechargeable batteries are through chemical reaction to the electronic energy storage capacity, so it is possible because the temperature, use the length of time, load and use frequency and environment. Below is about how to maximize optimize the maintenance of the battery in order to prolong the using time of the battery. To begin, the best after the battery charging it completely good electrical again after using it. Now some brand notebook charging mechanism has become very intelligent. The power supply will be auto discharge laptop battery power, only in the lower 95% automatically charge. So you don’t have to worry at ordinary times when using it will be charge. Suggest you every few months to a depth discharge to optimize the performance of the battery. Practice is used batteries, has been used to battery capacity to 0% (when the system will automatically into suspended animation or standby, according to the different). Then connected with ac recharger to 100% has so far.
Firstly, starting with the simplest of power management mode, each with a different operating systems of power management mode, specific Settings are in a Windows XP, for example (similar to other systems in control panel), there is a “power options” (figure 1), open source “options”, “the power options properties window (figure 2), in the” power use “selection box,” the household/desk “and” portable/pocket type “, “demonstration”, “open” and “minimum power management”, “Max battery model” and the manufacturers of than pattern etc. When choosing a different power allocation, the project will be displayed after below the setting of different power allocation. Generally speaking, the laptop to choose “portable/pocket type” is more appropriate, of course, can also according to customer’s demand to set. But here the author suggest, shut off hard disk and monitor, the standby system were set up for time to 5 minutes, 15 minutes and 30 minutes, also can not sleep mode and use standby system, because more electricity than the standby dormancy, but enable hibernation required part of disk space.
