HP EliteBook X G1i 14 AI laptop review: Basic features wrapped in an executive package

The EliteBook X G1i 14 doesn't offer any standout specifications or features, but what's here is done right and of very high quality for business users who just want the best lightwell clamshell without distracting extras.

HP Elite x360 1040 G11 2-in-1 review: For the business road warrior

The HP Elite 1000 family is lauded for its portability and auxiliary features that business users can appreciate. The latest Elite x360 1040 G11 continues the trend, but a bigger cooling solution probably wouldn't hurt to keep those core temperatures down.

HP ZBook Firefly 14 G11 laptop review: Core Ultra update with Nvidia RTX A500 graphics

The model can be configured with 14th gen CPUs starting from the Core Ultra 5 125U up to even the Core Ultra 7 165H. However, it's clear that the form factor was designed more for U-series CPUs in mind rather than the more demanding H-series.

HP Victus 16 (2024) laptop review: RTX 4060 power paired with long runtimes

A Core i7-14700HX, GeForce RTX 4060 and 16 GB RAM should be enough for FHD gaming with at least high settings. The combination of Power Delivery and very good runtimes makes it easier to use the laptop on the go. Its price is currently just over US$1,600.
