RAM upgradability
This model has a single SODIMM socket, which supports up to 8GB of RAM (PC3-12800 DDR3L SDRAM 1600MHz SODIMM). The CPU does not support more than 8GB of RAM per SODIMM module.
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 Fn keys share keys with special functions (volume, brightness, etc.). By default the keys invoke the special functions, and require Fn keypress to invoke the usual F1 through F12 functions. To switch the role, use Fn-Lock (by pressing Fn and Esc).
Moreover, the End and Insert use the same physical key. When Fn-Lock is activated, the key default to Insert, and End is invoked as Fn+Insert, which many users find inconvenient. To switch the End and Insert functions, in modern Linux distribution, add the following in a new file /usr/lib/udev/hwdb.d/61-ThinkPad-X240-keyboard.hwdb, and then run sudo udevadm hwdb --update :
# ThinkPad X240: switch End and Insert keys (so that when Fn-Lock is enabled, {{key|End}} works without {{key|Fn}})
