Business laptop for everyday work

This 14.0-inch HP ProBook 640 G4 is built for professionals who need a reliable Windows 10 Pro machine for office tasks, web browsing and video calls. The Intel Core i5-8350U processor runs at 1.70GHz with 16GB of DDR4 memory and a 512GB SSD for fast boot and load times. Integrated Intel UHD 620 graphics handle standard business applications without a discrete card.

Cooling and power profile

The low-power U-series chip keeps heat output modest during typical document and browser workloads, so fan noise stays low in quiet offices. Battery life is rated under 3 hours, so the included AC adapter will be needed for most of the working day. Power draw remains light thanks to the solid-state drive and efficient 8th Gen architecture.

Upgrade path and limits

The 512GB SSD and 16GB of memory cover most productivity needs, while the board supports up to 32GB if heavier multitasking arises. Buyers who want more storage or a dedicated GPU for creative rendering should look elsewhere. The 1366 x 768 non-touch panel also means this unit is not suited for colour-critical design work.

Questions about this item

How do I install additional memory in the HP ProBook 640 G4, and which step is most often missed?

Remove the base cover, insert the DDR4 SODIMM module at an angle until the clips click, then reattach the cover; the step most often missed is pressing the module down firmly until both retention clips lock audibly.

Which component will need replacement first during the laptop's lifespan?

The lithium-ion battery is rated for under three hours of run time and will degrade with charge cycles, so it is the first part likely to require replacement.

What performance limit appears first when the Core i5-8350U runs sustained workloads?

The integrated Intel UHD 620 graphics share system memory and thermal budget with the CPU, so graphics-intensive tasks hit thermal throttling and memory bandwidth limits before the processor reaches its maximum turbo frequency.
