Lenovo Thinkpad T440s
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. In particular, Linux and Windows fails to boot, and MemTest86+ crashes, when using a 16GB SO-DIMM module, model IMM2G64D3LSOD8AG-B15E from Intelligent Memory (which does work in a ThinkPad X250).
Lenovo Thinkpad X240 (20ALA0K-WIG) Ultrabook (Core i5 4th Gen/4 GB/1 TB/Windows 8) vs Lenovo Thinkpad X250 (20CLA0EBIG) Ultrabook (Core i5 5th Gen/4 GB/1 TB/Windows 8) vs Lenovo Thinkpad X260 comparison on basis of storage, processor, display, ram, reviews & ratings and much more with full phone specifications at Gadgets Now. Lenovo ThinkPad X240 is a Windows 7 laptop with a 13.30-inch display that has a resolution of 1366x768 pixels. It is powered by a Core i7 processor and it comes with 8GB of RAM. I got a new corporate laptop, the X240 which was a replacement of the X230, and it was not clear at all that it was mounting only one memory slot. That was so sad. The other brands we have, ultrabook as well, are equipped with dual memory slots to have at least a maximum of 16Gb. That was very unusual to see from Lenovo.
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).
Moreover, End and Insert share 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:
Then run:# udevadm hwdb --update
