4 screws remove the left speaker and fan shield
The three buttons in the speaker grille control the speakers
From top to bottom it goes Volume up, Volume down and Mute.
Remove a single screw and pry the connector for the screen from the motherboard.
After the connector is removed, the 1680x1050 15 inch (38cm) screen is free.
The display enclosure
It is actually quite easy to do a DIY screen replacement as there is no glass or adhesive to deal with but there are tabs that snap everything together
Removing the 6 screws allows you carefully remove the bezel by carefully undoing the tabs with a flathead screwdriver.
I recomend using something made from soft plastic to undo the tabs as the plastic bezel and metal back panel damage easily.
The hinges simply screw on and off
The 1680x1050 Cold Cathode Fluorescent back-lit (CCFL) display
Hitachi model number TX39D99VC1FAA
Working and/or handling CCFL displays is dangerous as they contain Mercury and run at extremely high voltages.
Separating the top from the bottom
Carefully remove both speaker, SD card, Touchpad and Bluetooth module plugs and de-route the cable that leads to the wireless module (not pictured)
After that you can lift to top from the base.
The Interior of the top panel
Contains the right hand speaker, Bluetooth module and Touchpad assembly
Mouse and status LED daughter boards
The daughter board on top controsl the on/off mouse switch. The lower daughter board has status LED's, wireless on or off switch and headphone/microphone jacks
The touchpad sensor was intergreated into the palmrest and therefore was un-removable.
First thing to be removed from the motherboard is the fan.
There are (currently) no screws securing the fan in place so removal is as simple as pulling it out.
Make sure to unplug the fan first before removing.
The wires are very delicate and are very hard to repair. Carefully pull by the plug.
The left hand speaker, metal frame and wireless communications.
The wireless (gray) cable attaches to the frame so the frame can act like an antenna.
The speaker has the model number PK230005710.
This speaker also provides 1.5 watts of sound output.
The SD card reader is located right at the front of the computer and it's screwed into the base with a single screw.
The model number is LS-1704.

Next out is the CPU heat-sink.
It is held in with 4 sprung screws place around each corner of the CPU
The thermal paste on the CPU can be a potential health hazard. Try not to come into contact with skin.
It is recommended (but not absolutely necessary) to re-apply thermal paste once the heat-sink has been removed to avoid overheating issues.
And finally, the CPU
It's an Intel Celeron M 1.8GHz Single Core with 256k of cache.
55 million Processing Die Transistors
400MHz Front Side Bus (FSB)
Removal is as easy as turning the locking screw half a turn anti-clockwise to unlock and to then carefully lift up to remove.
CPU's are very delicate especially the pins and the thermal paste residue presents a potential health hazard.
Underneath an EMI shield (not pictured) we find the ATi Mobility Radeon 9200 graphics card.
64mb of dedicated graphical goodness
It is not integrated into the motherboard so if it fails it can replaced individually rather than having a whole motherboard or CPU replacement.
The notebook was available with the option of 32mb or 64mb dedicated graphics cards.
The removal of the motherboard.
The release button for the expansion card slot must be pressed and held in, in order to remove the motherboard.
