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.
