Lenovo Essential Wired Combo Keyboard and Mouse
PRODUCT DESCRIPTION
Lenovo Essential Wired Combo Keyboard and Mouse (4X30L79883) - Local Warranty
A Wired Keyboard and Mouse in One Box, With a Numeric Keypad
The Lenovo Essential Wired Combo pairs a space-saving keyboard that still has a numeric keypad with a 1600 DPI optical mouse, both wired on 1.8 metre cables. Nothing to pair, nothing to charge, and one part number to order for a whole desk.
A Correction to This Listing
Our previous version of this page stated a 1200 DPI mouse sensor, twice. Lenovo's own brochure gives 1600 DPI for this combo's mouse. The figure has been corrected, and the 1200 that appeared here does not come from any Lenovo document.
Spill Resistant, With Ten Million Clicks on the Mouse
The keyboard is spill resistant with membrane switches rated for up to 3 million clicks, and the mouse buttons are rated for up to 10 million. The keyboard's 2.5-zone layout keeps the numeric keypad in a compressed footprint — 424 x 146 x 20 mm.
Please Read: Lenovo Appears to Have Withdrawn This Model
Lenovo's US page for this part number now redirects, though it remains listed in several Asian markets. Lenovo has published no end-of-life notice, so we will not call it discontinued. Its functional successor in Lenovo's current range is 4X31R64400, the Essential Wired Combo with a Microsoft Copilot key — linked in the ordering table. Ask us about supply before standardising on this one.
Specification note. Lenovo does not publish PSREF specification sheets for most of its accessories, and for several products in this range it publishes very little at all. Every figure on this page comes from a named Lenovo document — a product datasheet, a Lenovo brochure or Lenovo's own product page — and the source is linked below. Where Lenovo publishes no figure, this page says so. Reseller listings for these products circulate detailed specifications that we could not trace to Lenovo, and we have left those out rather than repeat them. If a particular figure decides your purchase, ask us and we will get it confirmed by Lenovo before you order. Specifications and prices are subject to change by Lenovo without notice.

Compatibility & Fit
Buy a combo when you are equipping desks, not people. One part number, one carton, one line on the purchase order, and a keyboard and mouse that are guaranteed to match. For a new office fit-out, a training room or a batch of hot desks, that is worth more than picking the ideal individual devices.
Wired means it works on day one and every day after. No pairing, no dongle to lose, no batteries to source or replace across a floor of desks. On shared positions used by people who did not set them up, that reliability is the specification.
The numeric keypad in a compressed layout. Lenovo calls it 2.5-zone: the keypad is there, but the keyboard does not sprawl. At 424 mm wide it takes the same desk width as a full-size keyboard without the keypad. If your users work in spreadsheets or accounting software, do not buy a keyboard without one.
What Lenovo does not publish here. No connector type, no key travel, no tilt legs, no handedness for the mouse, no weights, no operating-system list and no box contents. If any of those decides the purchase, ask us and we will get it confirmed before you order.

Frequently Asked Questions — Lenovo Essential Wired Combo Keyboard and Mouse
What is the mouse's DPI?
1600 DPI, per Lenovo's own brochure. Our earlier version of this page said 1200 DPI in two places; that figure does not appear in any Lenovo document and has been corrected.
Does the keyboard have a numeric keypad?
Yes. Lenovo calls the layout 2.5-zone — a compressed arrangement that keeps the numeric keypad while holding the keyboard to 424 mm wide.
Is the cable USB-A or USB-C?
Lenovo does not say. Its brochure states only "wired via USB" with a 1.8 m cable. Ask us and we will confirm the connector before your order ships.
Is this model still available?
Lenovo's US page for this part number redirects, though it remains listed in New Zealand, Malaysia, Hong Kong and India. Lenovo has published no end-of-life notice. Its current equivalent is 4X31R64400, linked in the ordering table above — ask us and we will quote both and tell you which we can actually supply.
What warranty applies in Singapore?
Lenovo publishes a 1-year warranty for this combo. Note that its current replacement, 4X31R64400, and the Essential Wireless Combo Gen 2 both carry longer terms. Every unit SourceIT sells also carries local Singapore warranty support and a GST invoice.
