HP Envy 3SR51UA 2-in-1 laptop 12.3" Snapdragon 835 4GB 128GB UFS Windows 10 S Natural Silver

Snapdragon 835 2-in-1 for mobile professionals

This 12.3-inch detachable laptop runs on the Qualcomm Snapdragon 835 with eight cores clocked between 2.2 GHz and 2.6 GHz. It ships with 4 GB of onboard LPDDR4x memory and 128 GB of UFS 2.1 storage. Windows 10 in S mode and a built-in Micro SIM slot for 4G LTE keep the focus on cloud-first workflows away from a desk.

Sustained performance on passive cooling

The fanless design relies on the Snapdragon's low thermal envelope, so extended workloads stay at the base 2.2 GHz rather than the 2.6 GHz boost. Battery life reaches up to 22 hours of video playback and 19 hours of wireless streaming, while connected stand-by can last up to 1,000 hours. HP Fast Charge restores 90 percent capacity in roughly 90 minutes.

Windows 10 S and UFS storage limits

Windows 10 in S mode restricts software installation to the Microsoft Store unless switched out of S mode. The 128 GB UFS drive reserves up to 35 GB for recovery, leaving less space for local files and apps. Memory is soldered and not upgradable, and the single USB port handles data at up to 5 Gb/s, Power Delivery and DisplayPort 1.3, but there is no HDMI output.
