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. 
						

							4-2Service Guide4.1General Information
4.1.1Before 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 (1) pressing the battery compartment cover
release button, and sliding out the cover.  Then (2) pull out the battery pack.Figure 4-1Removing the Battery PackRemoving all power sources from the system prevents accidental
short circuit during the disassembly process. 
						

							Disassembly and Unit Replacement4-34.1.2Connector 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.Figure 4-2Using Connectors With LocksConnectors mentioned in the following procedures are assumed to
be no-lock connectors unless specified otherwise. 
						

							4-4Service Guide4.1.3Disassembly Sequence
The disassembly procedure described in this manual is divided into four major sections:
· Section 4.2:Replacing Memory
· Section 4.3:Removing the hard disk drive
· Section 4.4:Removing the keyboard
· Section 4.5:Disassembling the inside frame assembly
· Section 4.6:Disassembling the display
The following table lists the components that need to be removed during servicing.  For example,
if you want to remove the motherboard, you must first remove the keyboard, then disassemble the
inside assembly frame in that order.

Follow these steps to insert memory modules:
1.Turn the computer over to access the base.
2.Remove the screw from the memory expansion door and remove the door.The memory door screw is part of the memory door and does not
separate from the memory door.Figure 4-4Removing the Memory Door
3.Remove the memory modules from its shipping container.
4.Align the connector edge of the memory module with the key in the connector.  Insert the
edge of the memory module board into the connector.  Use a rocking motion to fully insert the
module.  Push downward on each side of the memory module until it snaps in place.
To remove the memory module, release the slot locks found on both ends of the memory slot
to release the DIMM.  Then pull out the memory module.Figure 4-5Installing and Removing Memory

the computer to hibernate properly.  If Sleep Manager is active, it
will automatically adjust the hibernation file on your notebook.If you are using an operating system other than Windows 95 or
DOS, you may need to re-partition your hard disk drive to allow for
the additional memory.  Check with your system administrator.
