Refurbished 14-inch ProBook with Ryzen 5 PRO

This refurbished HP ProBook 645 G4 delivers a 2.0 GHz quad-core Ryzen 5 PRO 2500U processor that boosts to 3.6 GHz. It ships with 16 GB of DDR4-2400 memory and a 256 GB NVMe drive. The 14.0-inch anti-glare panel runs at 1366 x 768 resolution. Windows 11 Pro is pre-installed for immediate productivity.

Integrated Vega graphics and single-channel memory

The AMD Radeon Vega graphics rely on shared system memory, so the single 16 GB DDR4 module limits graphics bandwidth. Wireless connectivity uses an Intel Dual Band Wireless-AC 3168 adapter supporting 802.11ac and Bluetooth 4.2. A Gigabit LAN port provides wired network access.

256 GB NVMe storage and 16 GB RAM headroom

The 256 GB PCIe NVMe SSD handles operating system, applications and active project files comfortably. Sixteen gigabytes of RAM keeps multiple browser tabs, office suites and light development environments running smoothly. Demanding creative workloads or large local datasets will exhaust storage and memory capacity quickly.

Questions about this item

Can the single 16 GB DDR4 2400 module be replaced with higher-capacity sticks later?

The laptop ships with one 16 GB DDR4 2400 SODIMM; the second slot is free, so you can add another matching module up to the platform limit.

What thermal limit appears first when the Ryzen 5 PRO 2500U runs at its 3.6 GHz boost for long periods?

The processor shares its cooling with the integrated Radeon Vega graphics, so sustained boost clocks are capped by the shared heat-pipe assembly rather than a separate GPU limit.

How loud does the fan get and how hot does the chassis feel during an all-day workload?

Under continuous load the single fan spins up to move heat from the combined CPU/GPU die, raising keyboard-deck temperature while fan noise remains at a moderate office level.
