Notebook battery Power saving techniques

Notebook battery Power saving techniques

In fact, how to make good use of Laptop battery, how to extend the laptop battery using time and life is problem for all notebook users, a problem. There are many laptop battery using tips in our daily life that we shoule know in normal use and application.

(A) quick to enter the dormant state

Do not use the notebook computer for saving latitude D820 battery power, we can set the power management program, let the system enter hibernation after a period of time, but it must wait a few minutes, is there a way to make the notebook computer system enter the sleep state immediately ?

There is a dormant easiest way in Notebook computer system : directly turn off the screen, you can make laptop to sleep immediately and effectively conserve battery power. When you need to use the laptop, only opening screen, the system will automatically return to the state before the operation.

(B) power-saving screen mode

Laptop TFT screen is the largest component of power consumption, in order to reduce power consumption, notebook computer manufacturers have devised ingenious schemes, in all the general advise are following tips: reduce the screen brightness, turn off the screen.

In some notebook power management as 40Y6795 40Y6797 40Y6799 settings to customize the brightness of the screen, the majority of notebook computers by a specific shortcut screen brightness adjustment, generally 6 to 8 level brightness adjustment.

(C) Carry out energy-saving settings

As desktop using the AC, most people may not take attention to energy-saving features, but to laptop user who must use Discount laptop battery for mobile use, the use of energy-saving features should be important. How to design computer hardware more energy-efficient, this is not a user problem. All us can do is set up the effective use of energy-saving options on the computer.

There are two energy-saving settings need to adjust the user: First, in the computer's BIOS setup program on the energy-saving mode in the settings; the most important thing is there are many in the operating system and operation of energy-saving settings. Computer system in the practical implementation of it, Windows system should take precedence over energy-saving settings in the CMOS settings.

1. BIOS settings of the energy-saving

In the CMOS settings,for example PCGA-BP2V PCGA-BP4V have a large "Power Savings", which can choose to "Maximum Battery Life" and "Maximum Performance" and many other options. "Maximum Battery Life" is the default setting of the energy-saving mode. Notebook computer model has several energy-saving state, such as the Idle Mode Idle Mode, Standby Mode standby (wait) mode, Suspend Mode flying (sleep) mode. Notebook computer these settings, are able to regulate power consumption, mainly in the computer to enter the energy-saving state, the timely closure of the system without the use of equipment.

Such as when waiting to close the display and hard disk; dormant, apart from the display and hard drive shut down, but also can save the contents of memory to the hard disk, the basic maintenance of the entire computer system shut down state, once activated, or restart your computer, desktop will be accurately restored to pre-hibernation state. Energy Saving in the CMOS settings, set up mainly to enter the Idle Mode from Standby Mode in Standby Timeout time set by the Suspend Mode to enter the Standby Mode of the time Suspend Timeout. Notebook Phoenix BIOS of most use. Different energy-saving BIOS settings may be somewhat different, we should carefully read the screen prompts.

2. Windows in the energy-saving settings

For general users, in the Windows system management for energy conservation may be a better understanding of the operation simpler. Windows help file, in the "management hardware and software" under the entry, two notebook computers with the contents of the relevant energy-saving: "the management of energy consumption" and "the use of portable machine" in the "management of the power portable machine." Energy-saving settings in Windows, should read it.

In the Windows "Control Panel", click "Power Management", you can open the "Power Management Properties" dialog box. In the "Power Management Properties" dialog box, should be "power scheme" is set to "portable / laptop" (Using 92P1101 92P1102 08K8193 08K8192 92P1087 92P1011 battery) and reasonable arrangement "system waiting for", "close the Monitor," "turn off hard disk" option, etc. . Different computer can control the options there will be some differences, the new factory and the latest computer software will be more workable options and detailed computer settings should be based on their functions and help files for Windows.

In addition, if your notebook computer with built-infrared port, close it when not in use, you can extend notebook battery life.
