The biggest feature of the laptop is its removable, and support the basis of its mobility, its power system, and then how to make better use of the laptop's power system?

Laptop power system Introduction

The mainstream notebook standard configuration power system includes a rechargeable battery and an external DC power supply. AC power.
Case, usually using an external DC power supply for laptop power supply, there is not much difference between the characteristics and common desktop.

1) rechargeable batteries

The laptop's power system is its flexibility and stability of the fundamental power system includes a power adapter, rechargeable battery and power management systems. The power adapter is used to connect an external power supply to charge the battery, and the battery is also embodied an important part of the laptop portability. Now most laptop lithium battery-powered, general sustainable work more than three hours, to meet the general needs to go to work.

2) charging techniques

Bought a new battery at least completely filled with a battery, then power exhausted, official use only 2 charge. When the notebook computer using the AC indoor best to remove the battery in order to avoid that it is often in a state of charge. Best off when charging laptop, the battery can be fully charged, do not unplug the power drop in the charge. Charging is complete, it should be used after 30 minutes. Also note that the general charge and discharge at least once a month regularly charge and discharge.

Laptop energy saving settings

Energy-saving settings include saving mode setting in the BIOS and set the Windows operating system, and the latter should take precedence over the former.

1) Set the power-saving options in the BIOS

Most of the CMOS option, one [PowerSavings] the optional [MaximumBatteryLife] or [MaximumPerformance] (default). Set saving options set by [1dleMode] (idle) enter [StandbyMode] (standby) [StandbyTimeout] the time and by the [StandbyMode] into [Suspend Mode] [SuspendTimeout] (sleep) time.

Laptop power saving mode IdleMode, StandbyMode, and SuspendMode etc. These settings are able to regulate power consumption, the computer power state, the timely closure without the use of system equipment. Into hibernation, turn off the monitor and hard disk, but also the contents of memory can be saved to the hard disk, the entire computer system off basic maintenance. Once activated, or restart the computer, the desktop will be properly restored to pre-hibernation state.

Laptop PhoenixBIOS majority. Different energy-saving BIOS settings may be somewhat different, should carefully read the screen prompts.

2) Set the energy-saving options in Windows

Power in the Windows help file management hardware and software under the theme two notebook computers with energy-saving related content: [managing energy consumption] and [use portables] [portable]. Should read these before setting the Windows power-saving options.

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

Close set to [Power Schemes] [portable / Teng on type and reasonable arrangements for the system waits] [Close monitor] and [hard] options. There are some differences between different computer selectable option, detailed settings should be based on the function of the computer itself and the Windows help file.

Need to completely run out of battery power, instead of looking for other discharge channels, and in the power scheme drop-down box, select [Always Open] option, the drop-down box waiting for [System] and [Turn off monitor] Select [never] option. Also allows the computer to automatically run some of the computational complexity of the 3D demo program, so can quickly use the power remaining in the dry batteries.

3) the use of third-party software

There are many utilities to monitor the use of state of the battery. Example, PowerCenter is a power monitoring tool, available free Download (me MBers.xoom.com, / TimothyBug / powercenter / index.htm). PowerCenter In addition to display battery percentage display the actual time in hours and minutes.

The PowerCenter Total displayed.

(1) FullDisplay: open windows to display detailed information, including the use of battery or AC power, the percentage of remaining battery and available time.

(2) CompactDisplay: use always displayed at the top of the window.

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

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

Remedial charging improper battery

I have a IBMThinkpad390/262650C notebooks, usually improper charging and discharging in addition to the battery is a nickel metal hydride type memory effect battery discharge time is less than 5 minutes left. Through the efforts of the author in the IBM home page to find a program, with its magic to save the battery discharge time is almost back to like-new condition.

In the the series battery refresh TP390/390e/390x site to download IBM introduced the program, which is a self-extracting program under DOS. Prepare a reliable quality formatted floppy disk, and then perform the following operations.

1) restart your computer, press Gateway 3522GZ Keyboard F8 to start multiple choice menu. Select safe DOS mode, enter the directory where the just downloaded file. Perform isbr01., read the warning required to insert a floppy disk, press the Enter key to start the self-extracting process.

2) use this floppy disk to restart the computer, the screen display Startingpc-dos. Note: The above action by the AC power supply.

3) Follow the prompts to unplug the AC power, the program automatically discharge nickel-metal hydride batteries, until the machine automatically turns off, indicating that the discharge has been completed. Tip: Do not see 0% on the end of the operation, but also be careful not to remove the floppy disk.

4) Let the battery cools, and then plug in the AC power, again using a floppy disk to restart the computer. Autoexec.bat run automatically refresh program prompts whether to continue. Click the Yes button, and then press Gateway NV5302U Laptop Keyboard Enter. Soon returned to the DOS prompt A:> completed.

5) Turn off your computer, but do not unplug the AC power, battery charging, until its power indicator light turns green.

The above procedure was repeated three times to get the best results.

In the computer, the CPU heat large CPU faster, power consumption, the greater the heat more. General cooling method relies mainly on the heat sink and fan. The bottom and the upper part of the motherboard, each with a metal heat sink. The location of the CPU, and assist in the cooling system to absorb the heat generated from the CPU. The cooling fan does not start, low air flow and high air flow and three files, depending on CPU temperature. The greatest advantage of this cooling method is low cost, it was accepted by most PC manufacturers.

In addition to cooling, the keyboard convection cooling is a very creative approach. We know that the laptop computer is thin, when the Gateway MP-07F33U4-4424H Keyboard to the motherboard, the bottom of the keyboard will be, and board contacts can just use the keyboard at the bottom of conduction of heat generated by the CPU out. The structure of the keyboard, each key has four holes, the heat is then discharged through the button hole, when the hot air discharged from the button hole, and the air flows from the button hole to replace the hot air.

In a large number of cooling technology, water-cooled heat pipe technology is IBM proposed a very effective cooling technology. The initial idea is to dig ice cream spoon, handle the heat through the air traffic control-oriented frozen ice cream, melting more soft can be dug out after eating. Cooling tube within the fiber and liquid heat transfer medium (mostly water), drawn into the vacuum tube, a section close to the CPU, the other end away from the CPU. It works is: under vacuum, the boiling point of liquid thermal conductivity of the medium is very low, if a section of the tube is heated, the media will evaporate, the tropics to the other end of the cooling and then flow back, and so forth, the heat is constantly being brought to go. The heat pipe has many advantages, no moving parts, no noise, do not consume energy, while a long time to work effectively.

In addition to the heat pipe technology in IBM's unique Toshiba laptop, cold, hot-plate cooling technology. Thermal efficiency has increased by approximately 6.5 times, so that the laptop cooling issues are effectively addressed. Many brand name notebook computers using heat pipe cooling, convection cooling keyboard, a thermostatically controlled fan three cooling methods.

Did not yet have the software to directly control the laptop fan is running, but by the HTL instruction can effectively reduce the CPU's heat. Windows2000/XP has built-in support HTL instructions.
