Oh other things I have done to the notebook:
* Upgraded to a Core 2 Quad Extreme (did that a week after buying the notebook - as usual it was many hundreds cheaper to buy the upgraded processor separately so I ordered it with a mid-range Core 2 Duo)
* Replaced both heat sink thermal transfer pads with copper shims when I replaced the motherboard after the lightning strike (and of course cleaned ALL of the dust out of every nook and cranny of the notebook while I had it torn down to the bare chassis)
* About six months ago the screen hinge FINALLY started to loosen up so I disassembled the screen assembly to tighten all the internal screws on the screen frame. Feels like new.
* Upgraded to hybrid hard drives about six years ago (so, not long after buying the laptop)
* Upgraded the RAM about four years ago
Aside from the above all I've done since is maintain the Windows 7 install (including defrag of MFT and shrinking/defragging registry hives) and update the Linux install (OpenSUSE - my preferred Linux distro for workstations). The processor is still plenty fast for sysadmin work, and even for software builds on occasion.
It has what is by far the best laptop screen I've used - and I do credit that to the RGB-LED backlight array, I've worked with newer Precisions, HPs, Asus, Lenovo, and other desktop/workstation replacement and gaming laptops and none of the screens compare.
