14" FHD Ultrabook for Mobile Professionals

The HP ProBook 640 G4 is a 14-inch Full HD laptop built for daily business use. It runs Windows 11 Pro on an Intel Core i5-8350U quad-core processor with a base speed of 1.7 GHz and a turbo up to 3.6 GHz. Integrated Intel UHD Graphics 620 handles standard visual tasks. The 1920 x 1080 IPS panel offers clear viewing angles without touch input.

USB-C Power Delivery and Legacy Ports

A single USB 3.1 Type-C Gen 1 connector supports Power Delivery and DisplayPort output for docking or charging. Three USB 3.1 Gen 1 Type-A ports connect existing peripherals. HDMI provides a direct link to external monitors. Wi-Fi 5 and Bluetooth 4.1 handle wireless networking and accessories. The chassis relies on integrated graphics, so no discrete GPU power is required.

8 GB DDR4 and 256 GB SSD Baseline

The system ships with 8 GB of DDR4 memory and a 256 GB solid-state drive. The memory ceiling is 32 GB for buyers who need more headroom. Storage options in the series extend to 128 GB, 512 GB or 1 TB, but this unit is fixed at 256 GB. Heavy multitasking or large local datasets will push against the standard RAM and capacity limits.

Questions about this item

How does the i5-8350U behave when all four cores run at 3.60 GHz for long periods?

The processor can reach 3.60 GHz on its four cores, but sustained loads will be limited by the ultrabook cooling system and 15 W power envelope.

What fan noise and surface temperatures should I expect during an all-day workload?

The slim chassis uses a single fan; under continuous load the keyboard deck and bottom can become warm and the fan runs audibly.

Which dock or charger do I need to drive the USB-C port with Power Delivery and DisplayPort?

Any USB-C Power Delivery charger or dock that supports DisplayPort Alt Mode will work with the USB 3.1 Type-C Gen 1 connector.
