A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an

During typical office work, the laptop doesn't ever get too warm to the touch, and the fans stay fairly quiet, which is great for anyone who works in an open-concept office or shares workspace with others. The HP Command Center app allows you to choose from four fan operation presets or manually control the cooling fan to suit your work. You can also use this app to monitor your fan speed and CPU temperature to catch problems before they escalate. HP Spectre x360 14 review: Verdict If you're looking to edit video on the go, know that our Spectre x360 14 review unit performed decently in our Handbrake video editing test, converting a 4K video to 1080p in just over 17 minutes. That's better than the 18 minutes it took our Dell XPS 13 review unit to complete the same task, but far slower than the 7:44 it took the MacBook Air to get it done. HP Spectre x360 14 review: Battery life We tested the HP Chromebook x360 14 (2021) with an Intel Celeron N4500 CPU, integrated Intel UHD Graphics, 4GB of RAM, and 32GB of storage in the Natural Silver color scheme. The CPU and integrated GPU, RAM, storage, and color scheme are configurable; see the table below for more options. It's closely related to the HP Chromebook x360 12 (2021), which is the 12 inch model with a 3:2 touchscreen display and similarly performing CPUs. There are other 14 inch models of this laptop, like the Chromebook x360 14a and Chromebook 14c, but they have different chassis designs and use CPUs with different architectures. To avoid confusion, our review only applies to variants with the model number "14b-cb". ScreenThe OLED screen covers 139.7% of the DCI-P3 color gamut (the non-OLED, 1920 x 1280 screen covered 74.6%). The next best was the ZenBook Flip S, also with an OLED display, at 113.1%. The MacBook Pro measured 78.3% and the XPS 13 2-in-1 covered 70%.

Next up is another synthetic graphics test, this time from Unigine Corp. Like 3DMark, the Superposition test renders and pans through a detailed 3D scene, this one rendered in the eponymous Unigine engine, for a second opinion on the machine's graphical prowess. We present two Superposition results, run at the 720p Low and 1080p High presets and reported in frames per second (fps), indicating how smooth the scene looks in motion.These things get loud — too loud, even. As I listened to Spotify, I turned the volume down as Fall Out Boy's "Bob Dylan" stormed through my apartment. The drums, vocals and guitars were clear. Bass was a bit quiet. I tried changing that manually in the Bang & Olufsen control center, but to a little effect. There are presets in that app, but I found most of them to be overkill. Upgrading the HP Spectre x360 14 The Spectre x360 14's 1920 x 1280-resolution panel covers 75% of the DCI-P3 color gamut, making it more colorful than the panel on the XPS 13 2-in-1 (70%) and about as vibrant as the Yoga 9i's (76%) 14-inch display. The competition is no match for the Spectre x360 14's 3K2K OLED display option, which covers an astonishing 140% and demolishes the category average (86%).

The previous HP Spectre x360 also performed well in this test, scoring 10 hours and 55 minutes. Nevertheless, the extra half an hour is welcome, and it means the more powerful components haven’t come at the cost of battery life. After playing a 15-minute, 1080p video, the underside of this convertible, near the vent, reached 104 degrees Fahrenheit. That's considerably hotter than our 95-degree comfort threshold, so consider buying a cooling pad. Like the 2022 model and models before, the 2023 Pavilion x360 14 features a plastic chassis, but it still feels solid and well-built. The silver paint finish does a good job of imitating metal. The hinges that hold the two parts together are very solid and beefy affairs that hold everything firmly in position no matter how you set the Pavilion x360 14 up.Even better, the HP killswitch is a physical shutter over the camera rather than a software webcam deactivation, since in the latter case, malicious actors can reactivated your webcam remotely with a little bit of malware. Software killswitches are really only good enough to let you easily shut off your camera when you need to step away from the meeting, but that's about it.
