Hewlett Packard uses an elegant, matte-black metal case in the Envy. It did not turn out particularly maintenance friendly. In order to remove the bottom of the case, you have to first remove the two rubber strips at the bottom, since most of the screws hide behind them.
The computer is run by a Ryzen 5-4500U APU whose performance unfortunately remains behind its capabilities, since it is only able to offer performance bursts for brief time periods. During constant load, the clock speed drops fairly quickly. Usage of computer games is only possible to a limited extent, since the frame rates keep dropping repeatedly.
The IPS touchscreen scores with a good contrast, stable viewing angles, and decent color reproduction. However, the maximum brightness and color space coverage turn out too low. The touchscreen can be operated with the fingers as well as the HP Pen (1MR94AA; approx. 30 to 40 Euros; ~$35-47), which can optionally be purchased separately.
The convertible does not offer a Thunderbolt 3 port. Instead, HP has equipped it with a USB Type-C 3.2 Gen 2 port that supports DisplayPort and Power Delivery via USB C. The Envy can be recharged using the included proprietary power supply as well as a universal USB charger. The battery life turns out very good, and with a WLAN runtime of almost 9.5 h, most users should be able to get through the day without a charger.
