Compact All-in-One for Everyday Work

This 21.5-inch touch-enabled all-in-one runs Windows 11 Pro on an Intel Processor N100 with 16GB DDR5 and 1.12TB of combined storage. The integrated display, wired keyboard and mouse create a tidy workspace for office tasks, web apps and video calls. It suits small desks, reception areas or home offices that need a single-cable setup.

Steady Performance on Long Sessions

The four-core N100 is built for low-power efficiency rather than burst speed, so it maintains consistent throughput during extended document editing, browser tabs and light multitasking. Intel UHD Graphics handles the 1920 x 1080 panel and external displays via HDMI or USB-C 3.1 without thermal throttling under typical business loads. Sustained workloads stay smooth because the processor’s power envelope matches the all-in-one cooling design.

Quiet Thermals and Modest Power Draw

Passive-leaning cooling keeps fan noise low in a quiet room while the system idles or streams 720p video calls. The low TDP of the N100 means the chassis stays warm to the touch but not hot during a full workday. Wi-Fi 6 and Bluetooth 5.3 add minimal power overhead, and the external 1TB docking station draws its own supply so the main unit’s draw remains modest.

Questions about this item

How much heat and fan noise does the Intel N100 generate when the all-in-one runs all day?

The N100 is a low-power 4-core processor designed for efficient multitasking, so the system stays cool and quiet during extended work sessions.

Do I already need a separate keyboard, mouse or monitor to use this HP all-in-one?

No — the unit includes a 21.5" FHD touchscreen, a wired keyboard and a wired mouse, so it works straight out of the box.

Can I connect my older USB 2.0 peripherals and an external HDMI display to this PC?

Yes — it provides two USB-A 2.0 ports, two USB-A 3.0 ports and one HDMI port for legacy devices and a second screen.
