Replacement Keyboard for HP ProBook 450 G6 / 455 G6 / 455R G6 / 450 G7 / 455 G7 / 455R G7

Restore your HP ProBook 450 or 455 to factory condition with this Lemonyy replacement keyboard, covering the G6 and G7 generations of HP’s mainstream 15.6″ business ProBook lineup. The ProBook 450 G6, 455 G6, 455R G6, 450 G7, 455 G7, and 455R G7 all share the same keyboard deck dimensions, ZIF connector interface, and silver-frame aesthetics. This is a 15.6″ full-size keyboard with numpad and no TrackPoint — designed for HP’s mid-range business consumer audience.​

Both backlit and non-backlit variants are available for this keyboard family. The backlit version includes a secondary ZIF connector for the LED strip; the non-backlit version has a single data connector only. Confirm which variant your original laptop uses before ordering — the connectors differ physically.​

⚠️ CRITICAL — G6 and G7 Have Different Installation Methods:
Despite sharing the same keyboard part, the ProBook 450/455 G6 and G7 use completely different keyboard mounting systems. Confirm your generation before starting this repair:​

HP ProBook 450/455 G6 — Easy-to-Moderate (HP Push-Tool System):
HP officially documents this repair with a dedicated tutorial video:​

• Remove the service cover and the 2.5 mm P1 Phillips screws labeled with keyboard icons.​
• Place the laptop on its side with the display open and insert a keyboard release tool through the base enclosure opening to gently push the keyboard up.​
• Rotate the keyboard toward the front to access the ZIF connectors.​
• Lift the ZIF locking bars and disconnect the keyboard data cable and (if applicable) the backlight ribbon cable.​
• Reverse all steps with the new keyboard.​

HP ProBook 450/455 G7 — Moderate-to-Difficult (Adhesive + Motherboard Removal):
The G7 revision removed the push-tool mechanism and switched to an adhesive-bonded keyboard. Confirmed by technicians in the field:​​

• Remove the bottom cover and all internal components including battery, SSD, fans, heatsink, and RAM.
• Remove the main board entirely to access the keyboard adhesive bond from the underside of the chassis.​​
• Carefully separate the keyboard from the top case using controlled force to break the adhesive tabs.​
• Secure the replacement keyboard with new adhesive and reassemble in reverse order.​

⚠️ Backlit vs. Non-Backlit — Confirm Before Ordering:

• Non-backlit (V181646BS1 / L45091-001): Single ZIF data connector.
• Backlit (2B-BBU20Q100 / V181646CS1): Dual ZIF — data + backlight.

To verify: press Fn + F5 on your HP ProBook — if a backlight icon appears on the key, your laptop has a backlit keyboard and you must order the backlit variant.​
