Lenovo ThinkPad T490s - spare parts, FRU numbers and how to choose

Q: Do parts from the ThinkPad T14s fit the T490s?

In the vast majority of cases, yes. The T490s and T14s Gen 1 are practically the same laptop - Lenovo renamed the series in 2020 - so they share cases, palmrest, cables, battery, ports and panels. That is why many original parts list both designations. Note: do not confuse it with the thicker T490 (without the "s") - that is a different design. For the motherboard, match strictly by FRU number.

Q: What battery does the T490s have and which one to choose?

The T490s has an internal battery (mounted inside, not replaced from the bottom). The matching cell (shared with the T14s) is in the Main batteries section above - choose by the FRU number of your current battery. Separately there is a small CMOS battery backing up the BIOS settings.

Q: What charger does the T490s use? Does an old Slim Tip fit?

Important difference: the T490s charges via USB-C (USB-C Power Delivery), NOT via the rectangular Slim Tip plug like older ThinkPads (T460s/T470s). You need a USB-C 65 W charger (or a more powerful one with PD support). Old Slim Tip chargers do not fit. A suitable USB-C charger is in the Docks and power section.

In short: in a Lenovo ThinkPad T490s you can replace virtually every component - from the battery, palmrest and cables, through cases and the display, to the motherboard. The T490s is almost identical to the later ThinkPad T14s, so many parts are shared. The most reliable way to match the right part is the FRU / Part Number printed on the original component. We confirm model compatibility against the official Lenovo Hardware Maintenance Manual and the laptop's As-Built number, so each part lists verified compatible models and replacement numbers. Below is the full list of T490s parts grouped by component - click to go to the offer.

Frequently asked questions about T490s parts

Do parts from the ThinkPad T14s fit the T490s?

In the vast majority of cases, yes. The T490s and T14s Gen 1 are practically the same laptop - Lenovo renamed the series in 2020 - so they share cases, palmrest, cables, battery, ports and panels. That is why many original parts list both designations. Note: do not confuse it with the thicker T490 (without the "s") - that is a different design.

What battery does the T490s have and which one to choose?

The T490s has an internal battery (mounted inside, not replaced from the bottom). The matching cell (shared with the T14s) is in the Main batteries section above - choose by the FRU number of your current battery. Separately there is a small CMOS battery backing up the BIOS settings.

Which LCD display cable should I choose for the T490s?

It depends on the panel: the T490s came with a Full HD panel, a Full HD touch panel and a version with a PrivacyGuard privacy filter - each has its own eDP cable with a different FRU number. A cable incompatible with the panel will result in no image, so first determine your display type and then choose an item from the Display, cables and hinges section.

Palmrest for the T490s - with or without a fingerprint reader?

Choose a palmrest matching your configuration: versions differ in the presence of a fingerprint reader and in the keyboard layout. If your laptop had a reader, take a palmrest with a reader. Variants (some shared with the T14s) with FRU numbers are in the Palmrest, keyboard, touchpad section.

Which motherboard fits the T490s?

The T490s used Intel 8th generation processors (Whiskey Lake), in i5/i7 versions with various memory and an optional WWAN modem. The board is soldered with the processor, so it is matched strictly by FRU number - check the marking of your current board or give us your configuration.

What charger does the T490s use? Does an old Slim Tip fit?

Important difference: the T490s charges via USB-C (USB-C Power Delivery), NOT via the rectangular Slim Tip plug like older ThinkPads (T460s/T470s).

How do I check the FRU number of a T490s part?

The FRU number (Part Number) is printed on the component itself - on the battery, palmrest, cable or board. It is the most reliable way to choose. We described how to read it in our guide How to read a Lenovo FRU number.

Which T490s parts are replaced most often?

The most frequently replaced are the battery (it loses capacity over the years), the display cable and hinges, the palmrest and the USB-C port (it wears out from plugging in the charger). You will find all these items in the list above with their FRU numbers.
