Ready for Mobile Professionals

The HP ProBook 640 G4 is a 14 inch ultrabook built for professionals who need a reliable Windows 11 Pro machine with a bright 1920 x 1080 IPS display. It ships with 32 GB of DDR4 memory and a dual-drive layout combining a 256 GB M.2 drive and a 1 TB SSD for ample local storage. The quad-core Intel Core i5-8350U runs at 1.7 GHz and can reach 3.6 GHz when workloads demand it.

Sustained Workload Behaviour

Under continuous load the integrated Intel UHD Graphics 620 shares system memory and thermal headroom with the processor, so extended rendering or heavy multitasking will throttle clock speeds below the peak turbo figure. The 6 MB L2 cache helps keep frequent data close, but the 15 watt design envelope means the chassis warms noticeably during long compile jobs or video exports. Fan noise rises steadily but remains acceptable for office environments.

Build and Daily Connectivity

The silver aluminium unibody resists flex and gives the 14.0 inch frame a rigid feel on a desk or lap. A single USB 3.1 Type-C Gen 1 port handles power delivery and DisplayPort alt mode, while three USB 3.1 Gen 1 Type-A ports and HDMI cover legacy peripherals and external monitors. Wi-Fi 5 and Bluetooth 4.1 provide wireless links, and the integrated webcam supports conferencing without extra dongles.

Questions about this item

Does the Intel Core i5-8350U stay quiet and cool when the 32 GB DDR4 memory and dual SSDs are active all day?

The 1.7 GHz quad-core processor with integrated UHD 620 graphics runs at a 15 W TDP, so fan noise remains low during typical office workloads even with both drives and full memory in use.

What cables or peripherals must I already own to use the USB 3.1 Type-C Gen 1 port for power delivery and DisplayPort output?

You need a USB-C cable that supports Power Delivery and DisplayPort Alt Mode, plus a monitor with a USB-C or DisplayPort input; the laptop supplies up to 5 V / 3 A through the port.

Can I keep using my older USB-A flash drives and HDMI monitor with the three USB 3.1 Gen 1 Type-A ports and the HDMI output?

Yes, all three Type-A ports are backward-compatible with USB 2.0 and 3.0 devices, and the HDMI port drives legacy 1080p displays without adapters.
