Key Features

Everything you need in one device

🛡️

Built to last

MIL-STD-810H testing covers drop, shock, vibration, dust, humidity and temperature extremes. A spill-resistant keyboard and reinforced chassis make the B3404 a sensible choice for hard-wearing fleet and education deployments.

🧰

Dual SO-DIMM RAM

Two DDR5 SO-DIMM slots, upgradeable to 32 GB, let IT teams right-size memory and extend device life - the kind of serviceability that keeps total cost of ownership down across a long refresh cycle.

⚙️

Core Ultra option

Configurable with Intel Core Ultra 7 155U or Core Ultra 5 125U (with AI Boost NPU) for current AI-PC workloads, or value 13th-gen Core i7/i5 silicon where budget leads the decision.

🔌

Complete connectivity

Thunderbolt 4 (USB4), USB-A 3.2 Gen 2, a USB-C with power delivery, HDMI 2.1, native RJ45 Gigabit Ethernet and a smart-card reader - a full legacy and secure-network port set without a dock.

🔒

Fleet security

TPM 2.0, optional TCG Opal 2.0 self-encrypting SSD, Absolute Persistence 2.0 firmware tracking, a webcam privacy shutter and a Kensington Nano lock slot. Higher SKUs add an IR camera for Windows Hello.

🎮

Optional RTX 2050

The B3404CVF configuration adds a discrete NVIDIA GeForce RTX 2050 - useful headroom for light CAD viewing, photo work and GPU-accelerated tasks in an otherwise mainstream business laptop.

♻️

Sustainability credentials

EPEAT Gold, ENERGY STAR 8.0 and TCO Certified, with recycled-material content - helpful for organisations with procurement sustainability targets and ESG reporting requirements.

About the ExpertBook B3 (B3404)

The ASUS ExpertBook B3 (B3404) is the durable, cost-effective member of the ExpertBook family - aimed at general business and education fleets that need ruggedness and serviceability more than flagship weight or an OLED screen. It clears MIL-STD-810H durability testing and pairs a spill-resistant keyboard with a reinforced 14" chassis built for daily knocks.

Configurability is the appeal for IT buyers. Memory is dual DDR5 SO-DIMM, upgradeable to 32 GB; storage is M.2 PCIe 4.0 NVMe with an optional TCG Opal 2.0 self-encrypting drive and, on some SKUs, a second drive slot. Silicon spans Intel Core Ultra 7 155U / Core Ultra 5 125U with an AI Boost NPU for current AI-PC workloads, down to value 13th-gen Core i7/i5 options where budget leads.

Connectivity is comprehensive for the price band: Thunderbolt 4 (USB4), USB-A 3.2 Gen 2, a USB-C with power delivery, full-size HDMI 2.1, native RJ45 Gigabit Ethernet and a smart-card reader. Displays run from a 14" WUXGA anti-glare IPS at 300 nits to a brighter WQXGA 500-nit option on the B3404CVF, which can also be specified with a discrete NVIDIA GeForce RTX 2050 for light GPU work. The lightest configuration starts at 1.40 kg.

For UK organisations, the B3 is the practical fleet and education choice - durable, serviceable, secure with TPM 2.0 and Absolute Persistence 2.0, and carrying EPEAT Gold, ENERGY STAR 8.0 and TCO Certified credentials for procurement. Servnet supplies it through the ASUS commercial channel with same-day UK quoting, VAT recovery, leasing and warranty uplift, configured to your build standard.

FAQ

Frequently Asked Questions

Q. How durable is the ExpertBook B3?

The B3404 is tested to US MIL-STD-810H, the same military-grade durability standard ASUS applies across the ExpertBook line - covering drop, shock, vibration, dust, humidity and temperature extremes. Combined with a spill-resistant keyboard and reinforced chassis, it is built to survive the daily handling of general business and education fleets.

Q. Does the B3 have a fingerprint reader and IR camera?

It depends on the configuration. The premium B3404CVF SKU includes a 1080p FHD IR camera for Windows Hello face sign-in; other SKUs ship a 720p webcam with a privacy shutter and a fingerprint option. Tell Servnet which biometric sign-in you need and we will quote the correct SKU.

Q. Can I get discrete graphics in the B3?

Yes - the B3404CVF configuration can be specified with a discrete NVIDIA GeForce RTX 2050. That provides useful headroom for light CAD viewing, photo editing and GPU-accelerated tasks beyond what the integrated Intel graphics deliver, while keeping the laptop within a mainstream business price band.

Q. ExpertBook B3 vs ExpertBook B5 - what is the difference?

Both are durable, SO-DIMM-upgradeable business laptops. The B5 sits a tier above: brighter WQXGA panel as standard, current-generation Core Ultra vPro silicon, Wi-Fi 7 and optional 4G LTE, plus a 16-inch B5604 size. The B3 is the more cost-effective, value-silicon choice with the same MIL-STD-810H durability - ideal for budget-led and education fleets.

Q. ExpertBook B3 vs Dell Pro 14?

Both target mainstream, manageable business fleets. The B3 leads on serviceability with dual SO-DIMM upgradeable memory and a built-in smart-card reader, and offers an optional RTX 2050. The Dell Pro 14 brings Dell's ProSupport service options and management tooling. Choose on TCO, service contract and whether upgradeable RAM matters to your refresh strategy.
