  • Pointing devices
    • TrackPoint (with 3 physical buttons)
    • UltraNav touch pad

Disassembly

Any internal component replacement or upgrade (including hard disk and expansion cards) requires opening the back cover. Keyboard replacement requires full assembly and disassembly of the system board, and fresh thermal paste for the CPU heatsink.

Opening the case involves two stages:

  • Opening a handful of screws (these have tiny retainer rings made of transparent plastic; be careful not to drop them when removing the back cover).
  • Carefully prying apart dozens of little fragile plastic latches. This requires a plastic case opening tool to avoid damage (a metal screwdriver will nick and scratch the plastic).

Key mapping

This model has a 6-row keyboard, where the F1 through F12 share the same top-row physical keys with special functions keys (volume, brightness, etc.). By default, the top-row keys invoke the special functions, and require Fn keypress to invoke the usual F1 through F12 functions. To switch the role and have the top-row keys default to F1 through F12, enable Fn-Lock mode (by pressing Fn+Esc).
