Lenovo Flex 4 14 80SA0000US 14″ 2-in-1 Laptop (Intel Pentium, 4GB RAM, 500GB HDD, Black)

Lenovo Flex 4 14 80SA0000US 14 2-in-1 Touch-Screen Laptop (Intel Pentium, 4GB RAM, 500GB HDD, Black)

With a price tag of around $350, the 14-inch Lenovo Flex 4 14 80SA0000US is among the cheapest 2-in-1 Windows laptop computers. For that money, it offers lower-end components delivered in the popular 2-in-1 touch-screen PC form factor with fully foldable screen. The notebook has a fairly light weight of 3.9 pounds and plastic chassis in black color.

The 14″ screen of the Flex 4 14 80SA0000US laptop / tablet hybrid has multi-touch functionality, but in other aspects it’s just another budget-class panel. It has an entry-level screen resolution of 1366 x 768 pixels, as opposed to pricier notebooks with sharper Full HD 1920 x 1080 screens. Furthermore, IPS technology for wide viewing angles is missing.

Besides the touch-screen, you can interact with the system via traditional laptop keyboard and touchpad. The keyboard has no backlight, which is not a surprise given the budget nature of the Flex 14 80SA0000US.

Another trade-off for the low price is performance. The notebook is based on the Intel Pentium (4405U) processor, which is a class below the mainstream Intel Core U series. Nevertheless, the Pentium is sufficient for the routine PC chores. For instance, web browsing, text processing, spreadsheet calculations, and online video and music services. As for gaming, only some non-demanding titles will work properly, since the integrated Intel HD graphics is among the weakest on the laptop market. Users who don’t plan to do anything more intensive on the laptop than noted here will very likely be satisfied with computing capabilities of the 80SA0000US model. As for multi-tasking ability, included 4GB of RAM is a satisfactory size for modest multi-tasking with a few web browser tabs and apps running at the same time. The laptop’s hard drive capacity of 500GB isn’t impressive. But, there’s still enough space on it for thousands of documents, hundreds of .mp3 songs, or tens of stored DVD-quality videos. Speaking of DVDs, it’s worth noting that this model doesn’t have a built-in DVD drive.

But, it does include the rest of usual and necessary laptop PC features. Namely, stereo speakers, a web camera for video chats, 802.11AC Wi-Fi wireless and Ethernet LAN networking interfaces, HDMI external display output, two USB 3.0 ports and one older USB 2.0, a headphones / mic jack, a multi-format media card reader, and Bluetooth.

Lenovo rates battery life of the Flex 4 14 80SA0000US at up to 8.5 hours.

The unit ships with Windows 10 Home OS version pre-installed.
