I have an old Sony VAIO PCG-35 that still works great, but
it is kind of falling apart. It has a broken hinge, a broken keyboard, and the
left and right buttons on my touch pad are starting to come loose. I bought an
old PCG-35 carcass for parts and I found this handy site for disassembly.
Problem is the site describes the disassembly of the PCG-25,
which is slightly different that the PCG-35. To remove the display, the screws
holding in the lower end display hinges in the chassis must be accessed. In the
PCG-35, the left hinge screws are blocked by a part of the CPU, heatsink, fan
assembly. I removed this assembly when disassembling the carcass, it just
popped out when I pried on it carefully after I removed the three screws. But I
thought better of it before attempting the removing the CPU assembly on my
working computer. I did a search and found this service manual.
And this is where my concern deepened. The manual describes
a locking screw that must be unlocked and then locked when the CPU is
reinstalled otherwise the CPU may become unstable. However, since the CPU is
glued to the bottom of the heatsink/fan assembly there is no way to access
the CPU locking screw when removing it or installing it! It doesn’t make sense,
what am I missing here?
