Serviceable design
Unusually for a modern thin-and-light, memory is DDR5 SO-DIMM across two slots - upgradeable to 32 GB after purchase. That serviceability extends fleet lifespan and simplifies IT spares versus soldered-only rivals.

About the ExpertBook B5 (B5404 / B5604)
The ASUS ExpertBook B5 is the volume workhorse of the ExpertBook line - the model most UK organisations will issue across general knowledge-worker fleets. It comes in two sizes: the 14" B5404 for mobility and the 16" B5604 for desk-bound, spreadsheet- and document-heavy roles, both built on the same Intel Core Ultra vPro platform and MIL-STD-810H durability standard.
Its standout fleet trait is serviceability. Where most modern thin-and-lights solder their memory, the B5 uses DDR5 SO-DIMM across two slots, upgradeable to 32 GB after purchase. For IT teams that means longer device lifespans, simpler spares and the ability to right-size memory mid-life. Storage is M.2 PCIe 4.0 NVMe with an optional TCG Opal 2.0 self-encrypting drive, and some SKUs add a second drive slot.
Connectivity is built for managed estates rather than minimalism: dual Thunderbolt 4 (USB4), dual USB-A 3.2 Gen 2, full-size HDMI 2.1, native RJ45 Gigabit Ethernet, a smart-card reader, Wi-Fi 7 on select SKUs and optional 4G LTE in some territories. The 14" B5404 starts at 1.29 kg; the 16" B5604, which can be configured with discrete NVIDIA GeForce RTX graphics, is the option for light CAD viewing and GPU-accelerated analytics.
For UK buyers, the B5 is the sensible mid-market default: vPro manageability, upgradeable RAM, a bright WQXGA IPS display, a fingerprint power button, Absolute Persistence 2.0 and TPM 2.0 - all at mainstream fleet pricing. Servnet supplies it through the ASUS commercial channel with same-day UK quoting, VAT recovery, leasing and warranty uplift, and can match CPU, memory, storage and panel choice to your fleet standard.
