Lenovo ThinkPad T540p parts — FRU numbers

Q: Do parts from the ThinkPad W540 or T440p fit the T540p?

Partly. The T540p shares its keyboard, display cable and some antennas with the W540 (same Haswell generation, W540 being the workstation version with a Quadro card) and with the smaller 14" T440p. Match the motherboard and any parts specific to the chosen graphics card strictly by FRU number — despite the similarity, these are separate designs.

Q: What battery does the T540p have and which one to choose?

The T540p has an external battery, replaceable from the bottom of the case without opening the laptop (shared with the T440p and W540). We currently do not stock a main cell for the T540p - ask us if you need one. A CMOS battery backing up the BIOS settings is available (the CMOS batteries section above) - choose it by FRU number.

Q: Which LCD display cable should I choose for the T540p?

It depends on the panel - the T540p came with an HD (1366x768, wedge) panel and a Full HD / 3K (2880x1620) panel. Each type has its own cable with a different FRU number (shared with the W540); an incompatible cable means no image. First determine your display type, then choose an item from the Display, cables and hinges section.

Q: Which keyboard fits the T540p?

The T540p shares its keyboard with the whole T540p / W540 / W541 / L540 / T550 / W550s family - choose a variant matching your language layout (e.g. QWERTY US/UK) from the Palmrest, keyboard, touchpad section.

Q: What charger does the T540p use?

The T540p charges with a high-power rectangular (Slim Tip) adapter of 170 W (shared with the W540/P50/P51/P70/P72) - choose a wattage no lower than the original.
