3.1.3 Disassembly Sequence

The disassembly procedure described in this manual is divided into four major sections:

• Section 4.2: Installing memory

• Section 4.3: Removing the modem board

• Section 4.4: Removing the hard disk drive

• Section 4.5: Removing the keyboard

• Section 4.6: Disassembling the inside frame assembly

• Section 4.7: 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.
