Lenovo Essential Wired Combo Keyboard & Mouse
PRODUCT DESCRIPTION
Lenovo Essential Wired Combo Keyboard & Mouse (4X31R64400) - Local Warranty
The Current Essential Wired Combo, With a Microsoft Copilot Key
The Lenovo Essential Wired Combo pairs a quiet keyboard with a numeric keypad and a dedicated Microsoft Copilot key with an ergonomic full-size mouse using a 1600 DPI optical sensor. Both pieces are wired, so there is nothing to pair, nothing to charge and no dongle to lose.
A Waterproof Membrane Under the Keys
Lenovo's own description is that a tough waterproof membrane can handle accidental spills. On a shared desk, a reception counter or anywhere near a coffee cup, that is the specification that determines whether a keyboard survives its first year.
Quiet Keys and a Space-Saving Layout
Lenovo describes quiet keys in a modern space-saving layout that still includes the number pad. Quiet matters more than it used to: in an open-plan office or on a video call, a loud keyboard is something colleagues notice.
What Lenovo Does Not Publish for This Part Number
Being straight about the gaps: no cable length, no connector type, no dimensions, no weights, no key travel, no tilt legs, no key lifecycle, no colour, no box contents, no operating-system list and no warranty term. Lenovo publishes no datasheet for this combo — only a product page. Reseller listings fill those gaps; we have not.

Naming

Compatibility & Fit
What the Copilot key actually does. It opens Microsoft Copilot directly on Windows 11, in the same way the Windows key opens the Start menu. If your organisation uses Copilot, it removes a click several times a day. If it does not, it is a key that sits unused — not a reason to buy or to avoid, but worth knowing rather than being surprised by.
Spill resistance is the specification that decides a shared keyboard's life. Lenovo describes a waterproof membrane under the keys. On reception counters, training rooms, staff kitchens and hot desks, that is what stands between a spilled drink and a replacement order.
Why buy the wired combo rather than the wireless one. One part number, one carton, no batteries to source, nothing to pair and no dongle to lose. For fitting out desks in quantity, the wired combo has fewer things that can go wrong at the point where someone sits down and expects it to work. The Essential Wireless Combo Gen 2 in the ordering table is the cable-free alternative, with a 3-year warranty and 65% recycled plastic.
The gaps on this page are Lenovo's. Lenovo publishes no datasheet for this combo — only a product page — so there is no cable length, no connector type, no dimensions, no key lifecycle and no warranty term to quote. Detailed figures circulate on reseller listings; none is traceable to Lenovo. If a particular one decides your purchase, ask us and we will get it in writing before you order.

Datasheet & Downloads
Lenovo publishes no datasheet, brochure entry or PSREF specification for this combo. Its product page, linked above, is the only Lenovo source and it carries marketing copy rather than a specification table — which is why this page has more gaps than our others.
Frequently Asked Questions — Lenovo Essential Wired Combo Keyboard & Mouse
What does the Copilot key do?
It opens Microsoft Copilot on Windows 11 directly, the way the Windows key opens Start. Useful if your organisation uses Copilot; harmless if it does not.
Is the connector USB-A or USB-C?
Lenovo does not say. Its product page states only that the combo "plugs into any USB port", and Lenovo publishes no datasheet for this part number. Ask us and we will confirm before your order ships.
How is this different from 4X30L79883?
4X31R64400 is the current model and adds a Microsoft Copilot key; 4X30L79883 is the previous one, which Lenovo documents more fully in its brochure but appears to have withdrawn in some markets. Confusingly, several Lenovo regional sites use almost the same product name for both. Both are in the ordering table above and we can quote either.
Does the keyboard have a number pad?
Yes — Lenovo describes a modern space-saving layout that includes the number pad.
What warranty applies?
Lenovo publishes no warranty term for this part number, so this page does not state one. Every unit SourceIT sells carries local Singapore warranty support and a GST invoice, and we will confirm Lenovo's manufacturer term before you order.
