ThinkPad X12 Detachable Gen 2 — 16 GB / 512 GB on a 12.3-inch detachable tablet with folio keyboard
This listing is one fixed configuration of the ThinkPad X12 Detachable Gen 2 (machine type 21LK), sold under Lenovo part number 21LK002YSG. Lenovo publishes 12.3-inch detachable tablet with folio keyboard for this machine type, with chassis dimensions of Tablet alone 283.3 x 203.5 x 8.8 mm; with folio keyboard 283.3 x 208.1 x 14.5 mm and weight Tablet 0.76 kg (1.67 lbs); with folio keyboard 1.1 kg (2.42 lbs). This configuration is in stock in Singapore.
What this exact configuration is
The distributor build sheet for this part number records the fitted processor as Intel Core Ultra 7 164U, the memory and storage as 16 GB / 512 GB, and the specifics on the display, camera, battery, wireless and Windows edition as reproduced verbatim in the This Configuration group below. Those are exactly the fields Lenovo's own book leaves open as options for the machine type.
AI PC positioning, per Lenovo
Lenovo's own AI PC Category value for the CPU on this part number is: Lenovo does not publish an AI PC Category value for this machine type or CPU on the fetched excerpt; no Copilot+ PC or AI PC badge belongs on this page.
Why this page has two specification tables
Lenovo's PSREF book is the authority on the machine type, but it lists the panel, the camera, the memory modules, the battery, the AC adapter, the wireless card, the keyboard backlight, the Windows edition and the warranty term as OPTIONS for the whole machine type and does not say which of them is fitted to any one part number. The distributor build sheet does say that for this part number, and it is reproduced below word for word in its own group. We keep the two apart on purpose so you can see which source each figure comes from. Where they disagree we print both readings and say so rather than quietly picking one, and we confirm with the distributor before shipping. Where neither source states a figure we write not stated instead of estimating it or copying it across from a neighbouring generation.
Warranty and service in Singapore
Lenovo publishes these base warranty options for this machine type: 1-year courier or carry-in service; 3-year (1-yr battery) courier or carry-in service; 3-year (1-yr battery) limited onsite service. Every 3-year entry is qualified (1-yr battery), so the battery cover runs one year and not three; that qualifier is printed here so you can see Lenovo's own wording. The distributor build sheet on this listing does not record a specific service upgrade; the shipped entitlement is Lenovo's base term for this configuration. Warranty entitlement is registered against the machine's serial number and we are happy to confirm the registered entitlement in writing before you order.
