HP ProOne 400 G1 All-in-One

The HP ProOne 400 G1 is a 19.5-inch all-in-one desktop that integrates the display and system components into a single black-and-silver chassis. It is powered by a 4th-generation Intel Core i5-4570T quad-core processor running at 2.9 GHz with 64-bit support. The system ships with 16 GB of DDR3 SODIMM memory and a 2.5-inch 256 GB SATA solid-state drive. Windows 10 Pro 64-bit comes pre-installed, along with a USB keyboard and mouse.

Suits office and home users needing a compact.

Buyers who want a space-saving computer for web browsing, document work, and video calls will find the integrated 1600 x 900 LED screen, built-in webcam, internal speakers, and DVD-RW drive convenient. The system includes wired Ethernet and IEEE 802.11a/b/g/n wireless connectivity for network access. It is not intended for users who require discrete graphics performance, upgradable graphics cards, or memory types other than DDR3 SODIMM.

256 GB SATA SSD determines storage speed

The 2.5-inch SATA solid-state drive provides the primary storage for the operating system, applications, and user files. Its 256 GB capacity and SATA interface set the baseline for boot times, application loading, and available space. Buyers needing significantly more internal storage or a different drive interface should consider whether this capacity meets their requirements before purchasing.

Questions about this item

How do I install the 16 GB DDR3 SODIMM modules in the 204-pin slots?

Open the rear access panel, align the notch on each 204-pin DDR3 module with the slot key, press firmly until the side clips click, then replace the panel and reconnect power.

Which component will need replacement first — the 2.5" 256 GB SATA SSD or the DVD-RW optical drive?

The DVD-RW optical drive has moving parts and a limited laser lifespan, so it typically fails before the solid-state drive under normal office workloads.

What thermal limit appears first when the Intel Core i5-4570T runs at 2.9 GHz under sustained load?

The integrated Intel HD Graphics 4600 shares the processor package, so the combined CPU and GPU heat hits the fan curve ceiling before either core throttles independently.
