The greatest feature of notebook PCs is its mobility, and support of its mobile nature of the foundation is its laptop battery power system, then how to make better use of the notebook computer's power system?

Notebook Power Supply System Introduction

Mainstream notebook standard configuration of the power system includes rechargeable battery and external DC power supply. In a case of AC power, usually using an external DC power supply for laptops, the use of characteristics and there is not much different from regular desktop computers.

1. Batteries

Notebook computer power Apple PowerBook G4 Battery supply system is its flexibility and stability of the fundamental power system including power adapter, rechargeable battery and power management systems. Power adapter is used to connect an external power supply and charging the battery, which reflects the notebook computer battery is an important part of portability. Most laptops now use lithium battery-powered, generally lasts about 3 hours or more, to meet the needs of the general going out to work.

2. Charging Tips

Bought a new fully charged battery at least once a power, then power exhausted, 2nd charge after official use. When the notebook computer when the indoor use of AC is best to remove the battery so that it always in charge state. The best off charging laptop, the battery can be fully charged, do not unplug the power in the charge half-way. Charging is completed, should be 30 minutes Apple PowerBook G4 15inch Battery before use. Also note that the periodic charge and discharge the general charge and discharge at least 1 month.

Energy-saving settings notebook

Energy-saving settings include settings in the BIOS settings related to energy-saving mode and Windows operating systems, and the latter should take precedence over the former.

1. BIOS settings in the power-saving options

CMOS, there are mostly in a Apple A1012 Battery [PowerSavings] option, and optional [MaximumBatteryLife] or [MaximumPerformance] (default) and so on. To set energy-saving options, the main set by the [1dleMode] (idle) to enter [StandbyMode] (standby) of [StandbyTimeout] of time and by the [StandbyMode] into the [Suspend Mode] in [SuspendTimeout] (sleep) time.

Energy-saving notebook mode IdleMode, StandbyMode and SuspendMode and so on, these settings have been able to regulate power consumption, mainly in the computer into energy-saving state, the timely closure of some without the use of the system equipment. In hibernation, in addition to turn off the screen and hard drive, but also the contents of memory can be saved to the hard disk, the basic maintenance of the entire computer system shut down. Once the activation or re-start the computer, the desktop will be properly restored to pre-sleep state.

PhoenixBIOS notebooks are most common. Different energy-saving BIOS settings may be somewhat different, it should carefully read the screen prompts.

2. Set Windows, power-saving options

In the Windows Help file in the [management of hardware and software] under the theme, two notebook computers with energy-related elements: [manage Apple M8511 Battery energy consumption], and [the use of portable machine] in the [management of portable computer power supply]. Set Windows power-saving options, should read the contents.

In the Windows-[Control Panel], double-click [Power Management] icon to open the [Power Management Properties].

The [Power Schemes] set to [portable / Teng on the model], and reasonable arrangements for [the system to wait], [close Monitors] and [Turn off hard disks] and other options. Different computer selectable options are some differences in detail the settings should be based on the computer's own features and Windows Help files.

If you need to completely run out of battery in the power, rather than look for other ways to discharge, then the [Power Schemes] drop-down box, select [Always Open] option, and in [the system waiting for] and [close Monitors] drop-down box, select [Never] option. You can also let the computer automatically run a number of the computational complexity of the 3D demo program, so that can quickly dry battery power remaining.

3. The use of third-party software

There are many utilities available to monitor the battery Apple M8244 Battery condition. For example, PowerCenter is a power monitoring tool available for free download (http://me MBers.xoom.com / TimothyBug / powercenter / index.htm). In addition to the amount of PowerCenter shows the percentage of battery, but also to show the actual time and hours of time can be used.

PowerCenter total of three kinds of display.

(1) FullDisplay: In the open window displays detailed information, including the use of battery or AC power, the battery percentage and the remaining time available.

(2) CompactDisplay: in use is always at the top of the window display.

(3) MinimizeDisplay: make PowerCenter reduced to the Windows task bar, display the information is relatively simple.

PowerCenter is also attached to a control center, can be made up to six kinds of warning. When the batteryApple A1079 Battery - down to a certain level, a timely warning to the user, save the file being processed. In order not to waste electricity and CPU resources, PowerCenter automatically detect the battery status changes.
