Replacement Keyboard for Lenovo IdeaPad 330-15 / 330-15AST / 330-15IGM / 330-15IKB / 330-15ARR / 720-15 / 720-15IKB

Description

Restore your Lenovo IdeaPad 330-15 or 720-15IKB to full working order with this Lemonyy replacement keyboard, built for Lenovo’s mainstream 15.6″ consumer laptop lineup across the 2017–2020 generation. The IdeaPad 330-15 family — covering AST (AMD A-series), IGM (Intel Gemini Lake), IKB (Intel Kaby Lake/Coffee Lake), and ARR (AMD Ryzen) variants — shares the same keyboard deck, connector interface, and ZIF cable routing on all submodels. The 720-15IKB, a higher-tier model in the same chassis generation, is also covered.

The keyboard is a standard 15.6″ consumer layout with full numpad on the right side and no TrackPoint navigation nub. Backlit and non-backlit variants may be available depending on your original configuration — confirm your laptop’s backlight spec before ordering, as the connectors differ between variants.​

This keyboard is also cross-compatible with the IdeaPad 320-15IKB, 320-15AST, 320-15IGM, S145-15IWL, S145-15AST, and 130-15IKB, all of which share the same keyboard part family. If your model is not listed in the 330-15 series but belongs to these families, this keyboard will fit.​
