HP Pavilion Wired Keyboard and Mouse 400 (4CE97AA)

HP Wired Office Set from the Pavilion Series — a full-sized membrane keyboard and a simple optical mouse, unified by a common style and designed for everyday work. Both devices connect to the computer via separate USB-A cables. The 100% layout retains the full keyboard setup with a numeric keypad, F-row, and navigation cluster, while the body length of 410 mm and a thickness of only 22 mm make the keyboard one of the thinner models among full-sized options.

At a weight of 490 g, the keyboard remains stable on the desk but is also easy to carry in a laptop bag — ideal for those who switch between home and office use. The keys have a low profile and an island-style membrane design, making typing feel similar to a laptop: short and quiet keystrokes without a pronounced tactile threshold. A distinctive feature of the HP Pavilion Wired Keyboard and Mouse 400 set is the four additional keys located above the main block, traditionally used for quick access to multimedia and system functions, setting it apart from basic office sets without dedicated buttons. Other multimedia functions, including volume control, are positioned on the Fn layer. The mouse in the set features a standard two-button design with a scroll wheel and a fixed sensor resolution of 1000 DPI — sufficient for office tasks, but limited for graphic work or gaming. Mouse dimensions are 119x65x32 mm — the body is designed for a medium hand and standard grip.
