For the duration of the laptop's battery life,only the battery capacity, but also the level of power consumption of the system, which is influenced by several factors: hardware features of the computer, software solutions used, as well as the state and settings of the system itself.
It is best to take into account the hardware features inthe time of purchase of the computer. If the battery life is critically important, when choosing a laptop, you should pay attention to devices with economical and super-economical processors. Budget configurations based on Intel Celeron will help save money, but will not allow you to extend battery life.
An economical laptop should have a sufficient amount of RAM - then the computer will not constantly access the hard drive to use the swap file.
An additional increase in profitability gives a choiceoptimal operating system. Today, the greatest battery life is demonstrated by mobile computers running Windows 7. According to unofficial tests, the new OS from Microsoft * is able to extend the time between recharges by 20-30 minutes. compared to previous versions of Windows XP and Windows Vista *. In any case, it is recommended to install the latest system updates to reduce power consumption.
Another small but important step in the struggle forincreasing energy efficiency - regular hard disk defragmentation. This procedure, repeated at least once every 2-3 months, will not only speed up the system, but will also save battery power by optimizing the hard drive.
