The bottom bezel isn’t the thinnest, but it is in fact helpful if you use it as a tablet. The bezel helps your thumb to have a good grip on your tablet-mode notebook. The other side bezels are however very thin and give you more viewing space.

On the top bezel of the display in the 81X20005US model,  is a 720p standard laptop’s webcam, which has nothing exceptional. However, Lenovo includes the physical privacy shutter with the webcam enabling you to physically cover your webcam when necessary.

In other words, you don’t need to tape your webcam to have more privacy of yourself.

Backlit Keyboard

Typing experience with the keyboard of this 2-in-one Lenovo Flex laptop is good, but if you have not owned a Lenovo’s laptop before, you will need to get used to it, just like with any new keyboards.

The backlit feature on this keyboard is a big plus since it will help you type in the dimmer surrounding, very handy for home office.

There is also a fingerprint reader sensor on the keyboard deck of the 81X20005US, which is a nice feature to have and works very well with Windows Hello from Windows 10 without installing additional programs.


The speakers on this 81X20005US are located on each side of the laptop, are fairly loud and crisp with stereo quality.

The audio quality is pretty decent for video conferences or watching movies, but if you want more, you can always use Bluetooth speakers or a headphone.

81X20005US Performance

The 81X20005US model comes with AMD’s Ryzen 5 4000 series, precisely, the 4500U, a 6-Cores/6 Threads 3MB L2 / 8MB L3 CPU with 2.3GHz base clock and max boost clock up to 4.0GHz. Due to its Cores and Thread numbers, this processor is a very efficient CPU to run multiple Windows programs, like streaming YouTube videos, editing photos, and other computing tasks.

Due to the integrated Radeon RX Vega 6 Graphics card, which paired with 16GB of RAM (without upgrading), and the SSD, this convertible laptop is capable to run some gaming titles. Of course, it won’t run heavy demanding games like a designed gaming laptop, but it is capable of some degree of gaming. Have a read about this gaming notebook that also packs AMD’s Ryzen CPU on this page if you really look for a specific machine to game.

Battery Life

Battery life is generally good, about 6-8 hours, though not as advertised (10-hours). It seems that the touchscreen and the backlit keyboard drain the battery life quickly. The good thing, however, you can charge it quickly, 80% power charge for about an hour.
