If you are using a laptop, how much knowledge do you think you’ve learned from laptop computer battery? As to the laptop which is long-standing connected to ac adapter, how to maintain the battery properly is still a big problem. Actually, it is the incorrect way of use that makes the battery life reduced.
Use direction of laptop computer battery
For most laptops, they have the function of automatic CPU down-conversion which is to extend the battery life to the most extent. Many users will be confused that if the laptop doesn’t have this function in it, does it mean that energy saving for laptop computer battery is unavailable? In fact, CPU is only a part of power consuming components. Sorted by power consumption, the result appears to be LCD, CPU, video card, wireless card and radiator fan. To reduce power consumption, all these components should be taken into account.
In the control panel of windows, there’s a power management options of the system. You can set the options according to your requirement. Here, we recommend that it is best to set idle time of LCD screen to 10 minutes while that of hard disk to be more than 15 minutes. As the starting of hard disk will consume much power, it is harmful to stop and restart the disk frequently.
To further save energy for laptop computer battery, it is also necessary to adjust the running state of system which is unavailable to windows xp. To take ibm thinkpad battery as an example, it has its own battery management software. Normally, a laptop screen has brightness adjusting of 8 grades. Although you may feel good under the brightest state, it really will cost you much power energy.
Therefore, if you are just editing some documents or other normal applications, the 6th and 7th grade are enough. Meanwhile, the CPU can also be set by options. For example, it is reasonable to set the state of CPU radiator fan to balance. Otherwise, not only the standby time but also laptop battery life will be reduced rapidly.
