Palm Rest Assembly and Track Ball Assembly
(HP Authorized Service Providers Only)
Before removing the Palm Rest Assembly or Track Ball Assembly the battery and the floppy disk drive modules (a second battery may be installed in to the floppy disk drive bay) must be removed. See instructions for removal of these two modules.
In the floppy disk drive and battery bays are four Phillips screws, two in each bay. Remove these screws while the unit is upside down. If the keyboard is to be removed withdraw the two Phillips screws under the Hard Disk Drive as shown in the illustration below.
