The display system can independently place either RGB or YUV data from anywhere in display memory into an on-screen window which can be any size and located at any pixel boundary (YW data is converted to RGB "on-the-fly" on output). Non-rectangular windows are supported via color keying.
The 64-bit wide memory configurations have double the memory bandwidth of the 32-bit wide configurations. The figure below shows the display memory configurations using and external STN-DD buffer: Some of the 32-bit configurations allow an additional 256K x 16 device to be used for an external 16-bit wide STN-DD buffer, as shown above.

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.
4.1.3 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...
Installing Memory Follow these steps to insert memory modules: Turn off the computer. Then turn the computer over to access its base. Remove three screws from the memory door; then lift up and remove the memory door. Figure 4-4 Removing the Memory Door Remove the memory modules from its shipping container.
Figure 4-5 Installing and Removing Memory Replace the memory door and secure it with the screws. Sleep Manager must be run after installing additional memory for 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.
Removing the Modem Board When you open the memory door, you can also access and replace the modem board. See figure below. Figure 4-6 Removing the Modem Board Service Guide...
Removing the Hard Disk Drive Follow these steps to remove the hard disk drive: Turn the computer over and locate the hard disk drive bay cover. Press the hard disk drive bay cover release and slide the cover out to remove it. Set aside the cover.
Removing the Keyboard Follow these steps to remove the keyboard: Slide out the two display hinge covers on both sides of the notebook. Figure 4-8 Removing the Display Hinge Covers Using a pointed instrument, unlock the keyboard locks. Then pull out and flip down the keyboard to expose the keyboard connectors.

Figure 4-24 Removing the Charger Board REMOVING THE PCMCIA SOCKETS The PC Card Connector Module is normally part of the motherboard spare part. The following removal procedure is for reference only.
4.6.8 Disassembling the Top Cover The touchpad, speakers, audio board are connected to the top cover. The sections below describe the removal process of these components. REMOVING THE HARD DISK DRIVE HEAT SINK Pull up to remove the hard disk drive heat sink from the top cover. Figure 4-26 Removing the Hard Disk Drive Heat Sink REMOVING THE AUDIO BOARD...
REMOVING THE TOUCHPAD Remove four screws and lift up the metal plate and touchpad buttons. Unplug the touchpad cable (J1) and remove the touchpad main sensor and connector unit. REMOVING THE SPEAKERS Unlock the speaker by pushing outward on its locks. The flip up the wire that holds the speaker in place and remove the speaker.
Disassembling the Display Follow these steps to disassemble the display: Remove the two oval LCD bumpers at the top of the display; use a pointed instrument to remove the two mylar stickers on the bottom of the display. Figure 4-29 Removing the LCD Bumpers Remove four screws on the display bezel.
Pull out and remove the display bezel by first pulling on the inside of the bezel sides and lower bezel area. Then pull up the top bezel area.
