Business touchscreen laptop for office workflows

This HP 15 business laptop pairs a 10-core Intel Core i7-1255U processor with 16GB of DDR4 memory and a 256GB PCIe NVMe SSD. The 15.6-inch full HD touchscreen runs at 1920 x 1080 resolution with a 60Hz refresh rate. Windows 11 Pro 64-bit comes pre-installed for professional environments.

Sustained performance with integrated graphics

The i7-1255U operates at a 1.70GHz base frequency and can reach 4.7GHz turbo across its 10 cores and 12 threads. Intel Iris Xe integrated graphics share system memory, so extended heavy workloads will be limited by thermal headroom and the 45W power supply rather than discrete GPU memory. The 41 WHr battery provides mobile runtime for typical business tasks.

Straightforward setup with limited expansion

The chassis measures 14.1 x 9.5 x 0.75 inches and weighs 3.5lb, fitting standard laptop bags without special accommodation. Connectivity includes HDMI, USB 3.2 Type-C, an SD card reader and a headphone jack, but there is no optical drive. Buyers who want more storage or user-replaceable memory will find the integrated design restrictive.

商品問答

Does the 45 W power supply and 41 Whr battery keep the i7-1255U cool and quiet during a full workday?

The 45 W adapter and 3-cell 41 Whr battery are sized for typical office loads; the 10-core i7-1255U runs at 1.7 GHz base with a 4.7 GHz turbo, so sustained heavy tasks will draw more power and spin the fan, while light use stays cool and quiet.

What cables or peripherals must I already own to use the HDMI, USB 3.2 Type-C and SD card reader ports?

You need an HDMI cable for external displays, a USB-C cable or hub for USB 3.2 Type-C devices, and your own SD cards for the reader; the laptop includes a headset jack but no USB-A or Ethernet adapters.

Will my existing 802.11ac router and Bluetooth 5.0 headset connect reliably to the built-in wireless?

Yes, the laptop uses 802.11ac Wi-Fi and Bluetooth 5.0, so current 802.11ac routers and Bluetooth 5.0 peripherals pair and operate normally.
