Lenovo Flex 5 14 (81X20005US) (2020)

 A 2-in-1 convertible with more power than it weighs is the Lenovo Flex 5 14. Additionally, it comes in a variety of configurations, so you can be sure to find a Flex that meets your requirements. The Lenovo 81X20005US under evaluation has strong computing performance compared to several competitors that cost more than twice as much.

In addition to having remarkable performance, it also boasts a well-designed chassis, good physical connectivity options, and a comfortable keyboard. Although the Flex 5 is a wonderful mainstream laptop and a screamingly amazing deal, we wish the screen were brighter and it could stand to weigh less.

Lenovo Flex 5 14 (81X20005US) (2020) Design

The design of entry-level devices from more established companies has improved recently, and the Lenovo Flex 5 is no exception. It's true that it isn't trying to compete with high-end hardware running on an Apple MacBook Pro platform. However, the machine looks nice and doesn't feel cheap.

Despite being made of plastic, the primary chassis feels sturdy and has a typical textured appearance. It is a 2-in-1 convertible laptop with a sturdy 360-degree hinge, and the keyboard is strong and firm with little any bend or bounce. Not the lightest 2-in-1 available, but also not the heaviest, at 3.6 pounds and 0.8 inches thick.

The selection of ports is superb. There is a full-sized HDMI port, a power connector, a headphone jack, and a USB-C port on the left side of the chassis. The latter permits laptop self-charging and lessens the drawback of the barrel connector. A 4-in-1 card reader that supports full-sized SD cards as well as MMC, SDHC, and SDXC cards is located on the left side along with a pair of USB-A ports. The 720p webcam on the top bezel, which has a physical shutter and support for an add-on digital input pen, is another feature worth mentioning.


The Flex 5's screen has a weak backlight with a brightness rating of only 250 nits, which is in addition to the relatively bulky chassis, is another obvious drawback. If you're working in a room that is lighted by natural light, you must set the screen brightness to its highest setting. The display works good in darker spaces, however it may be less visible in brightly lit spaces, like workplaces.

Full HD (1,920 x 1,080-pixel) IPS touch screen with compatibility for the Lenovo Digital Pen is featured on the 15-inch panel. The Lenovo pen, an additional that is optional, has two programmable buttons and 4,096 levels of pressure sensitivity. In contrast to the built-in digital pens found with high-end 2-in-1s like the Samsung Galaxy Book Flex and the Lenovo Yoga C940, this makes it a full-fledged stylus.

While integrated pens are less likely to go lost and can be charged through a slot built into the notebook, they are often smaller and less comfortable when used for prolonged sketching sessions.

Keyboard & Touchpad

The illuminated keyboard is cozy, and typing on it is a delightful experience because to the sturdy key switches. It's the same experience you get from the Lenovo IdeaPad S145; both offer nice typing experiences that won't annoy your coworkers at the office thanks to their good key travel, resistance, and key spacing. A set of specialized media keys for surfing, volume, and screen brightness are also included on the keyboard.

A decent trackpad with good feel to the touch and more give in the bottom left and bottom right, where the left and right buttons are, is located beneath the keyboard. It has a similar solid feel to that of the Apple MacBook Pro 13, but it is a bit stiff and occasionally inaccurate.


Rarely, especially at a fair price, does an ultraportable laptop have computational capability as one of its primary qualities. Even the priciest ones usually have sufficient power to do simple tasks like web browsing, but they struggle with more difficult ones like 3D gaming and rendering films. The Flex 5 is an anomaly due to its AMD Ryzen 5 processor, 16GB RAM, 256SSD, and Radeon graphics.

The majority of its rivals with similar price tags, such as the HP Pavilion x360 (14-dh2011nr), Acer Spin 5, and Lenovo Chromebook Flex 5, are powered by Intel Core i3 or Core i5 processors. In comparison to the previous alternatives, the Microsoft Surface Go 2 (MHM-00001), a 10-inch detachable hybrid tablet, employs an even less potent Intel Core m3.

Lenovo Flex 5 14 (81X20005US) (2020) Performance

When it comes to day-to-day performance on routine tasks like productivity and web browsing, as well as gaming and multimedia content creation, none of these rivals can equal the Flex 81X20005US. Additionally, Radeon graphics aid in producing content that needs a powerful graphics driver, but they might not be particularly noticeable when working with Adobe Photoshop projects.

The same is true when playing contemporary games; the majority of them operate at frame rates below 40 at 720p and low quality settings, indicating that you may anticipate significantly lower frame rates at high settings. Even though the Flex 5 isn't a gaming laptop, you may play on the lowest settings.
