+It is important to note that while the 2.5" IDE HDD is completely standard, it uses another of these unique, bespoke flat flex cables to interface with the motherboard:

+The Yamaha audio driver(s) do not install by default, as the PCI device ID of the particular chip in the Z505/Z600 is slightly different to that in other, similar models.
+To install it, edit the setup.inf file and add the following entry:
+TBC
+The ATI Rage card can be installed using ATI XL based drivers, it is not detected by the standard Windows 98 SE installation.
+==== Restoration Decisions ====
+Since there wasn't enough parts to make two good, working systems, I decided to pull the better parts from the PCG-Z600RE (the NeoMagic VGA model) and fit them to the PCG-Z600HE (ATI VGA model). This included:
+   * Internal trackpad flex cable
+   * Mini-USB plastic surround trim
+   * Keyboard/wrist rest panel
+   * Hinge covers
+   * Keyboard
+This leaves me with one missing screen hinge cover, the audio/iLINK trim piece, and the volume/USB trim piece to find.
+==== Cleaned PCG-Z600HEK ====
+After spending some time de-gunking the case, removing stickers and polishing up the general grime, the PCG-Z600HE came up looking quite nice:

+==== Size Comparison ====
+{{:blog:pentium:vaio:img20250207190132.jpg?600|}}
+Sony Vaio PCG-Z600HE on the left. IBM Thinkpad 240/240X on the right.
+Considering the Sony has a 12" screen compared to the 10" on the IBM, there's really not a lot in it.
+==== Cooling Upgrade ====
+Both laptops, when tested, had cpu fans running almost constantly, and when I investigated by taking apart the heatsink/fan from the PCG-Z600RE (both machines have identical cooling solutions) I found the thermal interface material had degraded to the point of going rock hard and extremely brittle. Clearly //not// conducting much heat at all!
+{{:blog:pentium:vaio:img20250208102328.jpg?400|}}
+I'll replace this on the working PCG-Z600HE with some modern material. Clearly thermal paste is not an option due to the thickness of the pad.
+I cleaned the original material off (it had gone completely hard) and replaced with a small section of Honeywell PTM7950:
+{{:blog:pentium:vaio:img20250318131918.jpg?400|}} {{:blog:pentium:vaio:img20250318131929.jpg?400|}}
+This seems to have stopped the fan from running at full speed all of the time. The little heatsink definitely gets rather warm with that PIII-800 though!
+==== Trackpad Connection Repair ====
+Both machines arrived in quite a state, with the cases loose, lots of screws missing, and in particular the trackpad cables chewed and torn.
+The header for the trackpad on the motherboard (this is the Neomagic motherboard) looks like this:
+{{:blog:pentium:vaio:img20250316143310.jpg?400|}}
+On the ATI motherboard it was broken (retaining clips for the cable snapped), so it was desoldered, leaving the solder pads looking like this:
+{{:blog:pentium:vaio:img20250316143341.jpg?400|}}
+The original flat cable is an **8-way**, **0.5mm** pitch part, but only around 10cm long - which definitely contributed to it getting damaged by the previous owner(s) upon disassembly of the laptop. I first tried cutting down another I had, but it was just easier to buy a ready made, generic 8-way, 0.5mm pitch cable. Original left, replacement right:

+One major difficulty in getting an OS on these machines is the lack of any built-in removeable media. The CD-ROM unit was a proprietary PCMCIA drive, and normal USB floppy drives are not supported as boot drives.
