Efficient Ways to Extend Laptop Work Time

Currently lithium batteries are widely used on laptops as backup power. So far, li-ion batteries, with features of rechargeable, long lifetime and great cycle times, are proved to an ideal power for laptop. Yet two many laptop users have complaint that work time of lithium battery is too short to meet their requirment.

In deed, this problem relates to inherent defects of lithium batteries, however, there are many ways to save laptop power in the application and inactive process.

a. laptop under use:
1. Turn down laptop screen intensity;
2. Playing CD, DVD or music would consumer much power. Only playing music when necessary;
3. Do not use laptop at too much high or low temperature;
4. Use correct AC power adapter;
5. Use battery management software standardly configured for laptops and select most proper power solution to
extend laptop work time;
6. Intel CPU has adopted a new Speed Step technology, which could reduce power consumption through adding basic frequency to lower CPU running in the mobile Pentium processor. In this system, battery optimization mode refers to a best balance striken between laptop performance and battery's work time, when laptop uses laptop. Therefore, according to presnet load condition, laptop could use Speed Step processor to auto adjust speed and save battery consumption.

b. in the idle status:
1. Turn off unused wireless receiver. Present laptop are commonly configured with battery mode matching its work status. Thus choose mode before using laptops;
