To resume work, open the display. (The computer may take several seconds to resume operation.)

Suspend Mode

If your computer is running the Microsoft Windows 95 or Microsoft Windows NT

® operating system, suspend mode stops almost all computer

activity, but leaves the computer ready to resume operations immediately in about 20 to 30 seconds. Use suspend mode whenever you leave the
computer unattended.

NOTICE: Windows 95 and Windows NT save data to random-access memory (RAM), not to your hard-disk drive, before entering
suspend mode. If the computer enters suspend mode while running on battery power, data loss from RAM can occur if the battery
discharges completely.

Suspend mode conserves battery power by turning off the microprocessor clock; the display; the hard-disk drive; the CD-ROM, DVD-ROM, or LS-
120 drive module (if installed); the external monitor connector; the external keyboard (if attached); the parallel port; the serial port; the touch pad;
and the diskette drive.

You can enter suspend mode immediately by pressing (or on an external keyboard if the

External Hot Key

option is enabled in the System Setup program).

When you enter suspend mode, the

power indicator

is not lit.

Resume from suspend mode by pressing the power button. The computer may take several seconds to return to normal operation.

Standby Mode

If your computer is running the Microsoft Windows 98 operating system, standby mode turns off the display, stops the hard-disk drive, and turns off
other internal devices so that the computer uses less battery power. When the computer resumes operation from standby mode, the desktop is
restored exactly as it was before entering standby mode.

NOTICE: Windows 98 saves data to random-access memory (RAM), not to your hard-disk drive, before entering standby mode. If the
computer enters standby mode while running on battery power, data loss from RAM can occur if the battery discharges completely.

You can enter standby mode by pressing .

To resume operation from standby mode, press the power button.

Suspend-to-Disk Mode

Suspend-to-disk (S2D) mode copies all system data to a reserved area

—the S2D partition—on the hard-disk drive and then turns off all power to

the computer. When you resume normal operation, the same programs will be running and the same files will be open that were loaded before you
activated this mode.

Place the computer in S2D mode if you intend to store the computer for longer than 40 days. S2D mode preserves the configuration information
stored in nonvolatile random-access memory (NVRAM). The reserve battery maintains this information, but it may run out of energy after 40 days.

If your system is running under

Advanced Power Management

(APM) mode, and if the

External Hot Key

option is enabled in the System Setup

program, you can enter S2D mode by pressing (or on an external keyboard). On a French keyboard, press
or .*

Resume operation from S2D mode by pressing the power button.

If you connect or remove devices while the computer is in S2D mode, the computer automatically recognizes the newly connected devices when it
resumes normal operation.

Some PC Cards may not operate correctly after resuming from S2D mode. If you encounter problems with a card,

remove and reinsert the card

NOTE: If an external monitor is connected when you close the display, the computer does not activate suspend mode. You can still use
the external monitor.

NOTES: On resumption from suspend mode, if a password is set, the computer displays the password prompt screen. At the password
prompt screen, if you do not enter a password within 2 minutes, the computer returns to suspend mode.
