Basic Power Management Schemes

This section discusses the basic schemes of power management when the computer is operating on battery power or using AC power.

Standby vs. Hibernation

Standby unlike hibernation mode does not store unsaved information on your hard disk; it's stored only in the computer memory. If there is an interruption in power, the information is lost. So before putting your computer on standby, you should save your files.

Changing Devices:

Do not change PC Cards while in standby or hibernate modes.

To enter the power management window complete the following:

1. Click Start > Settings > Control Panel.

2. Click Power Options icon to display the Power Options Properties window.

3. Click the Power Schemes tab to display the basic power management options.

Power Schemes Tab

4. Select the time that you wish each of the following actions to occur in Battery and AC power mode.

• Turn off monitor:

• Turn off hard disks:

• System standby:

• System hibernates:

Using Power Management Options 53

Turning off the monitor and HDDs will save a substantial battery power, therefore when in battery only mode select the shortest time practical.

a Hibernate Mode (Power Management or Manual Method)

When hibernation is used, your computer turns off and when you power up again, everything is restored exactly as you left it—including programs and documents you may not have saved or closed. Everything in memory gets saved to the HDD, and the monitor and hard disk get turned off.

If You Reinstall Windows:

You should re-establish hibernate in power options by opening Power

Options Properties window and click on the Hibernate tab then click “Enable Hibernation”.

Hibernate Tab

a Standby Mode (Power Management or Manual Method)

Standby is used mainly for conserving battery power in your notebook computer. It also gives you the benefit of getting right back to your work without waiting for the computer to restart. Standby turns off your monitor and hard disks, placing your entire system in a low-power state. When you return to your computer, restores your desktop exactly as you left it. It is recommended that you do not enter standby mode with less than 20% battery power.

5. Click OK to set your power management options and close the window.

Using the Hard Drive

Your computer includes a removable IDE (integrated drive electronics) hard drive. The IDE hard drive can store the data and programs your computer uses. The drive plugs into a connector on the system board.

The hard drive that comes with your computer has already been formatted. Do not format the hard drive. Doing so destroys all data contained on the drive. If you need to format a new drive, or want to erase all data on your existing hard drive, refer to the manual for your operating system.

Removing the Hard Drive

To prevent loss of data and damage to the disk, do not remove the hard drive while the computer’s power is on and do not drop or jar the hard drive.

To remove the hard drive from the computer:

1. If you are installing a new hard drive, backup the application and data files on the

old hard drive before removing it from the computer.

2. Turn the computer’s power off.

3. Close the LCD panel, and turn the computer over so that the bottom of the unit

faces up.

4. Remove the screw that holds the hard drive in place.

5. Pull the hard drive out of the computer.

(Re)Installing Windows and Device Drivers

Use System Recovery CD to (re)install OS and System Software CD to (re)install device' drivers.

The System Recovery CD is used to (re)install the OS and System Software to a new HDD or recover from a system crash.

Notebook computers that ship from the factory include a System Recovery CD-ROM and a System Software CD-ROM, which contains a copy of the applications and drivers needed for computer's operating system.

In the unlikely event that programs on the computer hard drive become corrupted or are erased, you can use the System Recovery CD-ROM to reinstall your operating system and then System Software CD-ROM to reinstall your original applications and drivers.

Video Features and Configuration

All these video modes can be displayed on an external monitor. However, if you disconnect an external monitor that was attached to your computer and then start the computer, the LCD may revert to a different resolution than the one you chose for the external monitor.

Resolution and Colour Depth

The resolution of the LCD is the sharpness of the image it can display. Resolution is measured by the number of pixels (individual dots) displayed on the entire screen. In general, the more pixels the LCD can display, the better the image.

The number of colours the LCD can display is measured by how many bits the LCD uses to represent each pixel:

• 16-bit colour can support 64 K (65,536) colours.

• 32-bit colour can support 16 M (16.8 million) colours.
