Tired of typing in the dark? This backlit keyboard is a perfect replacement for your HP Probook 640 G2, 645 G2, 640 G3, or 645 G3. It's brand new, unused, and comes in retail-ready packaging. The keys are backlit, so you can work comfortably in low-light conditions — perfect for late-night work sessions or dimly lit offices. It has a standard US layout with a pointer, so it'll feel just like the original. MPN is 840801-001, and it's compatible with the ProBook series. Made by an unbranded manufacturer, but don't let that fool you — it's built to match HP's quality. Includes a 6-month warranty for peace of mind. Manufactured in China. If your original keyboard is worn out or the backlight has failed, this is an affordable and reliable upgrade. Just plug it in and you're good to go!
