    Detailed Test Results

    Performance: Overall this laptop's performance was good, below that of many other models but still powerful enough for tasks such as email, word processing, web browsing, and streaming movies. Compared to other tested laptops, it was fast for common tasks such as web browsing and video conferencing. Applications start up quickly. Speed was adequate when composing documents, working on data spreadsheets, and other productivity tasks, and it was slow for manipulating images, editing videos, and calculating simulations. Graphical tasks run slower among other models with only integrated graphics.

    Portability: This laptop is a very good choice for traveling. Battery life lasted 13.75 hours in a light load of web browsing tests, and 10.25 hours in a heavier load of 4K video playback tests. Results were notably longer than many similar laptops, under a workload of mixed use. At 3.6 lbs, weight was typical for a laptop of this size category.

    Ergonomics: The keyboard was not full-sized, and might be uncomfortable for larger hands. Its high contrast letters were easy to read, and the backlighting can be useful in dark rooms. There's a dedicated number pad for faster data entry. The power button was conveniently located, but its labeling was hard to read when the laptop is off. Friction on the touchscreen may prevent fast swiping, and fingerprints may take some effort to clean off.

    Display: The display quality was good overall. Colors were in the ballpark, though not completely accurate. The display was anti-reflective, so there was little or no glare when viewing in a brightly lit room or outdoors. The display has a wide viewing angle, especially important if more than one person needs to see the screen at a time, say, for a video or presentation. Its display produces a smaller array of colors than on most other tested laptops.

    Useful features and attributes on this model include: Laptop has a touchscreen. The fingerprint reader lets you log into your computer without typing in a password.

    Downsides: No significant negative features.
