Business ultrabook for mobile professionals

The HP ProBook 640 G4 is a 14 inch Full HD laptop built around an 8th Gen Intel Core i5-8350U quad-core processor running at 1.7 GHz with a turbo up to 3.60 GHz. It ships with 16 GB of DDR4 memory and a 512 GB SSD, running Windows 11 Pro out of the box. The IPS panel delivers 1920 x 1080 resolution without touch input.

Step up from dual-core or 8 GB systems

This configuration replaces older dual-core ultrabooks or machines limited to 8 GB of RAM and smaller SATA drives. The jump is worth it when workloads regularly keep dozens of browser tabs, Office apps and a VPN open simultaneously. Buyers who need discrete graphics or user-replaceable memory will not find those options here.

Steady performance under continuous load

The integrated Intel UHD Graphics 620 shares system memory, so sustained 3D or video-encode tasks will hit thermal limits before the CPU reaches its maximum turbo for long periods. The 512 GB NVME drive maintains write speeds during large file transfers better than entry-level SATA alternatives. Wi-Fi 5 and Bluetooth 4.1 handle typical office traffic without dropping connections during long meetings.

Questions about this item

What is the maximum DDR4 memory capacity the ProBook 640 G4 can support?

The laptop accepts up to 32 GB of DDR4 RAM. The unit ships with 16 GB installed, leaving room for an upgrade if required.

How is the M.2 SSD installed, and what step is often missed?

Remove the bottom cover, insert the M.2 drive into the slot at an angle, then secure it with the single retention screw. The step often missed is fastening that screw before replacing the cover.

When will the 512 GB SSD likely need replacement?

A 512 GB SSD typically lasts several years under normal workloads. Replace it if SMART tools report declining health, write errors appear, or you need more capacity than 512 GB provides.
