ExpertBook B1 at S$1,499: the value business laptop
The ExpertBook B1 (B1403CVA) is the laptop to buy when the job is Microsoft 365, a browser full of tabs, Teams calls and line-of-business applications. The Core 7 150U is a 15 W part with two performance and eight efficient cores, enough for that work with the fan staying quiet. A full-size RJ45 port and HDMI output plug into an office or classroom without dongles, and two USB-C ports with DisplayPort and power delivery give a one-cable dock setup.
What makes it a fleet machine is the business plumbing: Windows 11 Pro for domain or Intune enrolment, TPM 2.0 for BitLocker, a webcam privacy shutter, a Kensington Nano slot, MIL-STD-810H testing and two SO-DIMM slots for a later move to 64 GB. At S$1,499, about S$1,349 with the code, it is the one we recommend for SMEs standardising a fleet, schools issuing staff machines, and students.
ExpertBook P3 at S$2,099: Core Ultra 7 255H with an NPU
The ExpertBook P3 (P3406CCA) is the step up for work that regularly makes a laptop sweat. The Core Ultra 7 255H is a 28 W, 16-core processor (six performance, eight efficient, two low-power efficient) with Intel Arc 140T graphics and an Intel AI Boost NPU rated at 13 TOPS; Intel quotes 96 platform TOPS across CPU, GPU and NPU. Large Excel models, Power BI, light Adobe or DaVinci work and local Python jobs run with headroom the B1 lacks, and the NPU takes Teams and Windows Studio Effects (background blur, eye contact, noise suppression) off the CPU during long calls.
The rest is upgraded to match: a 16:10 WUXGA 1920 x 1200 panel, a 50 Wh battery, Thunderbolt 4 for a single-cable dock, HDMI 2.1, Wi-Fi 7, a fingerprint sensor in the power key and an IR camera for Windows Hello, in a MIL-STD-810H chassis with a spill-resistant keyboard. To be clear, with a 13 TOPS NPU the P3 is not a Copilot+ PC (40 TOPS): it is a fast business laptop with AI acceleration for collaboration features, not a machine for running large models locally. For that, our ASUS Agent Computer guide covers the desktop options, and if you need 128 GB for local AI models, see RTX, DGX Spark and Intel/AMD laptops compared.
Which ExpertBook should you buy?
Buy the B1 if the laptop is for standard office work, you are buying five or fifty, or the user is a student. The S$600 saving per unit over the P3 (S$540 with the code on both) adds up across a fleet, and the B1 gives up nothing on manageability or warranty.
Buy the P3 if the user is a manager, analyst, engineer or designer who multitasks hard, lives in Teams with camera on, or works with data and media. Thunderbolt 4, Wi-Fi 7, the taller display, biometrics and the bigger battery matter to anyone who docks at the office and works elsewhere.
If the user never leaves the desk, a mini PC with the same Core Ultra 7 255H is cheaper per seat; see the ASUS NUC buyer's guide.
What 3 years local onsite warranty means
Both laptops carry 3 years local onsite warranty in Singapore: an engineer attends your premises rather than you carrying the unit in. For how ASUS commercial warranty claims work locally, read ASUS commercial warranty in Singapore. Confirm the exact term for your SKU when requesting a quote.
