							BIOS Setup Information3-73.3.6 Reset PnP Resources
The system resources are already properly configured. If resource conflicts arise, you can set this
parameter to Yes to reset and reallocate PnP resources, after which the BIOS automatically resets
this parameter to No, which is the default setting. 
						

							3-8Service Guide3.4 Power Saving Options
Selecting Power Saving Options on the BIOS Utility main screen presents a screen that allows you
to adjust several power-saving settings.
3.4.1 When Lid is Closed
The computer’s lid switch acts as its power switch: opening the display wakes up the computer,
closing the display puts it to sleep. The When Lid is Closed setting determines which suspend
mode the computer enters when the display is closed: Suspend to Disk or Suspend to Memory. The
default is Suspend to Disk.
· Suspend to Disk. With this setting, the computer saves all data to the hard disk when you
close the display. The computer wakes up when you reopen the display.
· Suspend to Memory. With this setting, the computer saves all data to memory when you
close the display or press the suspend hot key Fn+Esc (). The computer wakes up when you
reopen the display or press any key.Note:  If an external monitor is connected to the computer, the
computer will not enter suspend mode if you close the display.
To enter suspend mode, disconnect the external monitor,
open and reclose the display.Important!  Sleep Manager automatically creates a suspend-
to-disk file when it is run. If the file becomes invalid, suspend-
to-disk mode becomes unavailable, and the computer
automatically switches to suspend-to-memory mode.
3.4.2 Suspend to Disk on Critical Battery
With this parameter is set to Enabled, the computer enters suspend-to-disk mode when the battery
becomes critically low. The default setting is Enabled.
3.4.3 Display Always On
This parameter lets you specify whether the display is always on or not. When enabled, the screen
will not blank. To save power, the default setting is Disabled.
3.4.4 Resume On Modem Rings
You can set the computer to resume from suspend-to-memory mode upon detection of a specific
number of modem rings, ranging from 1 to 7. Enabling this option overrides the suspend-to-disk
function. 
						

							BIOS Setup Information3-93.4.5 Resume On Schedule
When this parameter is set to Enabled, the computer resumes from suspend-to-memory mode at
the specified date and time. Enabling this option overrides the suspend-to-disk function.
The Resume Date and Resume Time parameters let you set the date and time for the resume
operation. The date and time fields take the same format as the System Date and Time
parameters in the System Configuration screen.
If you set a date and time prior to when the computer enters suspend mode, this field is
automatically disabled. A successful resume occurring from a date and time match also
automatically disables this field. 
						

							3-10Service Guide3.5 System Security
When you select System Security from the BIOS Utility main screen, a screen appears that allows
you to set security options.Important!  If a password is currently present, the system
prompts you to input the password before entering the
System Security screen.
3.5.1 Supervisor and User Passwords
The supervisor and user passwords both prevent unauthorized access to the computer. When
these passwords are present, the computer prompts for the user or supervisor password during
system boot-up and resume from suspend. The supervisor password also gives full access to the
BIOS setup utility. The user password give limited access.Important!  The supervisor password must be set prior to
setting the user password. If you enter the setup utility with
the user password, you cannot modify the supervisor
password or certain BIOS settings.
To set a password, follow these steps:
1.Select the desired password (Supervisor or User) to set or edit, and press ® or ¬. A special
password prompt resembling a key appears:2.Enter a password of up to eight characters. (The characters do not appear on the screen as
you type them.) After typing your password, press Enter. The same password prompt
reappears:3.Retype your password and press Enter to verify your first entry.
After you set a password, the computer sets the Supervisor Password (or User Password)
parameter to Present. The next time you boot up, resume from suspend mode, run the BIOS setup
utility, or unlock system resources, the password prompt appears and you must type the supervisor
or user password to continue.Important!  The system continues to ask for your password
until you enter the correct password. If you forget your
password, you must reset the configuration values stored,
which requires opening the system unit. Contact your dealer
for assistance.
To remove a password, select the password you want to remove and press ¬ or ®.

This parameter allows you to control the read and write functions of the floppy drive. The available
options. are: Normal, Write Protect, and Disabled. The default is Normal.
With this parameter set to Normal, the floppy drive functions normally. When the parameter is set
to Write Protect, all write functions to the floppy drive are disabled, but you can still read from a
disk in the floppy drive. When the parameter is set to Disabled, the floppy drive is disabled.
3.5.3 Hard Disk Drive Access Control
This parameter allows you to control the read and write functions of the hard drive. The available
options. are: Normal, Write Protect, and Disabled. The default is Normal.
With this parameter set to Normal, the hard drive functions normally. When the parameter is set to
Write Protect, all write functions to the hard drive are disabled. When the parameter is set to
Disabled, the hard drive is disabled.
3.5.4 Start Up Sequences
This parameter determines which drive the system boots from when you turn on the system. The
following table describes the available settings.

Disassembly and Unit ReplacementDisassembly and Unit Replacement4-1This chapter contains step-by-step procedures on how to disassemble the notebook computer for
maintenance and troubleshooting.
To disassemble the computer, you need the following tools:
· Wrist grounding strap and conductive mat for preventing electrostatic discharge
· Flat-bladed screwdriver
· Phillips screwdriver
· Hexagonal screwdriver
· Tweezers
· Plastic stickThe screws for the different components vary in size.  During the
disassembly process, group the screws with the corresponding
components to avoid mismatch when putting back the components.
4.1 General Information
4.1.1 Before You Begin
Before proceeding with the disassembly procedure, make sure that you do the following:
1.Turn off the power to the system and all peripherals.
2.Unplug the AC adapter and all power and signal cables from the system.
3.Remove the battery pack from the notebook by (a) pressing the battery compartment cover
release button, and (b) sliding out the cover.  Then (c) pull out the battery pack.

							Disassembly and Unit Replacement4-34.1.2 Connector Types
There are two kinds of connectors on the main board:
· Connectors with no locks
Unplug the cable by simply pulling out the cable from the connector.
· Connectors with locks
You can use a plastic stick to lock and unlock connectors with locks.The cables used here are special FPC (flexible printed-circuit)
cables, which are more delicate than normal plastic-enclosed
cables.  Therefore, to prevent damage, make sure that you unlock
the connectors before pulling out the cables.  Do not force cables
out of the connectors.
CONNECTORS WITH LOCKS· Unplugging the Cable
To unplug the cable, first unlock the connector by pulling up the two clasps on both sides of
the connector with a plastic stick.  Then carefully pull out the cable from the connector.
· Plugging the Cable
To plug the cable back, first make sure that the connector is unlocked, then plug the cable into
the connector.  With a plastic stick, press the two clasps on both sides of the connector to
secure the cables in place.Unplugging
