How to make better use of the power system of notebook computer

Mainstream note standard configuration of the power system includes rechargeable batteries and external DC power supply. In the case of AC power, usually use an external DC power supply for the notebook computer, its use characteristics and ordinary desktop is not much different

1. Rechargeable battery

The power system of a notebook computer is fundamental to its flexibility and stability, and the power supply system includes a power adapter, a rechargeable battery and a power management system. The power adapter is used to connect external power supplies and recharge batteries, and the battery is an important part of laptop portability. Nowadays, most of the laptops are powered by lithium batteries, which can be used for more than 3 hours and can meet the needs of the general outside work.

2. Charging Tips

The newly-bought battery should at least be fully charged at a time, then the electricity will be exhausted, the 2nd time after the official use of the charge. When a laptop uses alternating current in the room, it is best to remove the battery so that it is often in a charging state. It is best to turn off the laptop when charging, so that the battery can be fully charged, do not unplug power in the middle of charging. The charge is complete and should be used in 30 minutes. Also pay attention to regular charge and discharge at least 1 times per month.

Energy saving settings for notebook computers

Energy-saving settings include setting up power-saving methods in the BIOS and setting up Windows operating systems, and the latter should take precedence over the former.

1. Set the energy saving options in the BIOS

Most of the CMOS has a [powersavings] option, optional [Maximumbatterylife] or [maximumperformance] (default), and so on. When setting energy saving options, the primary setting is [1dleMode] (idle) [Standbymode] (standby) [Standbytimeout] Time and [Standbymode] enters [Suspend Mode]. Suspendtimeout] (hibernation) time.

Notebook computer Energy-saving mode has Idlemode, Standbymode and Suspendmode, these settings can adjust the power consumption, mainly in the computer into energy-saving state, the timely closure of some unnecessary use of the system equipment. After entering hibernation, in addition to turn off the monitor and hard drive, can also save the contents of memory to the hard disk, the entire computer system to maintain the basic shutdown state. Once the computer is activated or restarted, the desktop is correctly restored to the state before hibernation.

The majority of the use of Phoenixbios notebook computers. Different BIOS energy saving settings may be different and you should read the ScreenTip carefully.

2. Set the energy saving options in Windows

In the Windows Help file, under the Manage hardware and software topic, there are two things about energy saving for laptops: Managing energy consumption and managing power on portable computers in portable computers. You should read these before you set Windows Energy saving options.

In Windows, in Control Panel, double-click the Power Management icon to open [power management properties].

Set [power scheme] to [portable/teng], and reasonably arrange options such as System wait, close monitor, and turn off hard disk. There are some differences in the options available to different computers, and the detailed settings should be based on the computer's own features and Windows Help files.

If you need to completely use the power in your battery without looking for other discharge paths, select the Always open option in the [power scheme] drop-down box and select the Never option in the system wait and close monitor drop-down boxes. You can also have your computer run some computationally complex 3D demo programs so that you can quickly use the remaining power in a dry battery.
