Display/video The OB4000 DSTN may report the display RAM to be 1024KBs, however, it is 512KB. Later versions have corrected this. It is not a hardware problem but a reporting problem. Display RAM is not upgradable. Display Manufacturer: Hitachi Video graphics controller chip: Western Digital 90c24 rocket chip. External video resolution (both types): Supports VGA/SVGA external monitors with up to 1024 x 768 x 256 colors in noninterlaced mode.
b. On OmniBook 4000CT models, if more than 30 total pixels anywhere on the display are bad, then the display should be considered for replacement. On OmniBook 600CT and OmniBook 5000CT models, if more than 15 total pixels anywhere on the display are bad, then the display should be considered for replacement.
Battery life can be doubled by installing second battery in place of the 3.5 " flexible drive. The OmniBook will recognize the additional battery and provide battery status of both batteries (can be installed hot). Smart Battery: The OmniBook 4000 uses "Smart" battery technology. The battery itself contains an ASIC (Application Specific Integrated Circuit) that is able to continuously test and track the status of the battery.

Notebook Hardware Structure Field Replaceable Assemblies Installing memory (End User Replaceable) The OmniBook 4000 family has two memory locations for expanding system RAM. The memory location on the side of the OmniBook that has the battery also has the factory RAM module installed. To add an additional 8MB or 16MB of RAM, use the location on the other side of the unit near the floppy drive.
Battery Module and Floppy Disk Drive Module (End User Replaceable) The Battery and Floppy Disk Drive Modules are user replaceable. A second Battery Module may be installed in the Floppy Disk Drive Bay. This doubles the battery life of the OmniBook 4000. To remove either module, turn the OmniBook over.
Hard Disk Drive (End User Replaceable) The Hard Disk Drive Module is user replaceable. To remove the Hard Disk Drive Module, remove the screw under the latch on the hard drive. Push the Hard Drive Module Forward - do not pull on the latch - it is not strong enough, use the back edge of the module in front of the depression in the bottom case instead.
Small parts (End User Replaceable) The I/R lens, expansion door, I/O door, Rubber feet, memory doors, and PCMCIA door are all replaceable. The I/R lens snaps in and out from the inside of the I/O door. To remove the I/O door, open it fully. Flex the door so that the center hinge separates from the backcase.
Icon Assembly and Display Module (HP Authorized Support Providers Only) To remove the display module on the OmniBook 4000C and CT turn the unit over and withdraw the two Phillips screws from the bottom back corners of the unit (see diagram below).
Turn the unit right side up and remove the Icon assembly by placing the thumbs on each edge of the assembly and pushing lightly (see diagram below). The front edge of the Icon Assembly will lift up slightly. Figure 5 - Icon Assembly ___________...
Lift the display straight up about 1 inch. The Icon Assembly will lift up with the display. Move the Icon assembly out of the way. The cable from the Icon Assembly to the PC board does not need to be removed if only the display is being removed.
Palm Rest Assembly and Track Ball Assembly (HP Authorized Support Providers Only) Before removing the Palm Rest Assembly or Track Ball Assembly, the battery and the floppy disk drive assembly (a second battery may be installed in to the floppy drive bay) must be removed.
Turn the unit right side up, open the lid and lift up on the palmrest. Disconnect the cable attaching the palmrest to the track ball assembly. To remove the track ball assembly, disconnect the Track Ball Assembly cable and remove the one screw that holds the Track Ball Assembly in place. The Track Ball Assembly then lifts out.
Keyboard Grounding Plate, CPU, and System Board (HP Authorized Service Providers Only) Required Equipment: • Phillips Screwdriver • Nutdriver (5 mm or 3/16 in) Components to remove prior Keyboard Grounding Plate, CPU, and System Board: 1. HDD, FDD, and Battery 2.
Enhanced Port Replicator (Exchange Assembly) The Enhanced Port Replicator (EPR) for the OmniBook 4000 contains no field replaceable components. If any component of the EPR is defective, the entire unit must be replaced. Troubleshooting Tips: • The OmniBook 4000 will only detect one pointing device at a time. Therefore, if an external mouse is connected to the EPR, the track ball will not be active.
