Large-screen touchscreen notebook

The HP 17-cn3145ds is a 17.3 inch HD+ touchscreen notebook built for everyday productivity and media consumption. Its anti-glare display and lift-hinge design support comfortable viewing and typing. The Spring Iridescence finish and included HP wireless mouse complete the package for home or personal use.

Thermals and power efficiency

The Intel Processor N100 quad-core architecture delivers performance suitable for web browsing and office work while maintaining low power draw. ENERGY STAR certification and EPEAT Gold registration reflect the system's energy-efficient design. Up to 10 hours of battery life supports extended sessions away from a power outlet.

Storage capacity constraint

The 128 GB UFS drive provides limited space for applications and local files, making this model unsuitable for buyers who need more storage. The 4 GB DDR4 RAM is soldered and not upgradeable, restricting multitasking headroom for heavier workloads.

Questions about this item

How do I connect an external monitor to the HDMI port and which display mode do people forget to select?

Plug the cable into the single HDMI port, then press the Windows key plus P and choose Extend or Second screen only instead of leaving it on Duplicate.

Which component will need replacement first when the 4 GB DDR4 memory fills up during multitasking?

The soldered 4 GB DDR4 cannot be upgraded, so the only way to gain more memory is to replace the entire laptop.

At what point does the Intel N100 processor hit its thermal limit during a long video-encoding session?

The quad-core N100 will throttle once its internal temperature target is reached, reducing clock speeds until the chassis dissipates enough heat.
