15.3" WUXGA touch display for office work

The 15.3 inch IPS panel shows 1920 x 1200 resolution with anti-glare coating and 300 nits brightness. Touch input and a 1080p IR camera with privacy shutter support video calls and Windows Hello sign-in.

Suits mobile professionals needing Windows 11 Pro

Business users get a backlit keyboard with numeric keypad, Wi-Fi 6, Bluetooth 5.3 and a 60 Wh battery in a 3.59 lb chassis. Buyers who need dedicated graphics memory or a higher colour-gamut screen should look elsewhere.

16 GB DDR5 memory soldered, not upgradeable

The system ships with 16 GB of DDR5 RAM and supports up to 32 GB maximum, but the memory is not user-replaceable. Confirm this capacity meets your workload before purchase.

Questions about this item

Does the 15.3 inch WUXGA touchscreen add any thickness or weight compared to a non-touch model?

The chassis measures 0.70 inches thick and weighs 3.59 lbs including the IPS anti-glare touch panel and 60 Wh battery.

How do I install a fresh copy of Windows 11 Pro on the 512 GB PCIe NVMe SSD without losing the OneKey Recovery partition?

Boot from USB, choose Custom install, delete only the OS partition, leave the hidden recovery partition intact, then let setup create its own partitions on the remaining space.

When the 3-cell 60 Wh Li-Polymer battery no longer holds a full day charge, can I replace it myself?

The battery is internal; removal requires unscrewing the bottom cover, disconnecting the cable, and swapping the pack — no soldering, but opening the case voids tamper seals.
