Business laptop with touch display

The HP 15-dy 2021 model pairs an 11th Gen Intel Core i5-1135G7 processor with 12GB DDR4 memory and a 512GB NVMe SSD. A 15.6-inch HD touchscreen running at 1366x768 resolution supports direct interaction for presentations and data entry. Windows 11 Home 64-bit comes pre-installed for immediate deployment.

Sustained workload behaviour

The quad-core i5-1135G7 operates at a 2.40GHz base frequency and can reach 4.1GHz under load while the integrated Iris Xe graphics share system memory. During extended sessions the 41WHr battery supplies power to the 60Hz panel and wireless radios without throttle events observed in typical office workflows. Thermal management balances clock speed and surface temperature across the chassis.

Thermals noise and power

A 45W power adapter replenishes the 3-cell battery while the fan remains inaudible during light productivity tasks. Under combined CPU and GPU load the cooling system increases airflow modestly, keeping the keyboard deck comfortable for continuous typing. Power draw scales with screen brightness and peripheral use on the USB 2.0, USB 3.1 Type-C Gen1 and HDMI ports.

Questions about this item

How much heat and noise does the 45W power supply and 41WHr battery produce during all-day use?

The 45W power supply and 3-cell 41WHr battery are sized for typical office workloads; fan activity will rise under sustained load but remains within normal ultrabook levels.

What cables or peripherals must I already own to connect an external monitor and wired network?

You need an HDMI cable for the 1 x HDMI port and an RJ-45 Ethernet cable for the built-in LAN jack; both ports are on the chassis.

Will my older USB 2.0 flash drives and SD cards work with the 2 USB 2.0 ports and SD card reader?

Yes, the two USB 2.0 ports and the SD card reader are backward compatible with legacy USB 2.0 drives and standard SD cards.
