The first impression about Lenovo Flex 3 15 (80R40006US) might be expensive. True, it’s not the cheapest model out there, but you’re also getting powerful components in exchange. Especially the Core i7-6500U (which, by the way, belongs to the 6th Generation) is a nice pick – surely something power users don’t mind having. Another pro is the Full HD display which is a requirement for many professionals. I’ll tell you more about the laptop’s features and possible weak points in the post below!

What is the notebook good for?

It’s quite simple, Lenovo Flex 3 15 (80R40006US) is good for heavy use. It’s powered by a brand new Intel Core i7-6500U, a dual-core processor based on the Skylake architecture, clock speed between 2.5GHz and 3.1GHz turbo. There are already some entries about it in CPU Mark benchmark, and the score it’s currently getting is around 4300. The older model, i7-5500U, seems to reach almost 4000 points so there’s almost 10% performance increase. Indeed, such an i7 is great for people who fancy a smooth operating computer, no matter how high system requirements their applications have.

In case you’re into multitasking you need a lot of memory. Well, this Lenovo sports 8GB RAM (the usual DDR3 low-voltage type), with that amount running many programs simultaneously is a walk in the park. It seems the 8GB is maximum you can have as there’s just one slot on the mainboard, hence upgrading memory shouldn’t be possible here.

The notebook is also good for storing heaps of data, the one terabyte 5400RPM hard drive makes sure of that. However, it’s not the best friend for the performance-minded. A solid-state drive is, luckily with little skills you can upgrade to SSD with this model, too.

This Lenovo is a device with a couple of “modes”. See, the 15.6″ touch display is not your typical screen, it rotates full 360 degrees. Hence, you’ll get to use this unit in both laptop and tablet modes (although it will be big and heavy tablet for sure!). The resolution is also nice 1920×1080, power users will probably like that.

What are its drawbacks?

As you could read above, Lenovo Flex 3 15 (80R40006US) is good for many things, but gaming is not its strong point. Sad news for the players, there’s nothing but an integrated graphics card speeding up your games. True, it’s a new Intel HD 520, but it still does not use dedicated memory, and that unit has similar performance to the more popular Intel HD 5500. Of course all hope is not lost: if you can accept low to medium settings and 720p resolution, playing many 2015 games – including the people’s favorite GTA 5 – is possible at 20-30 FPS. Older games than that, like Counter-Strike: Go and League of Legends, will work much better, even on 1080p.

What ports does it have?

You’re welcome to plug in three USB devices to Lenovo Flex 3 15 (80R40006US), it features one USB 2.0 and two USB 3.0 ports. In case you want a bigger screen, you can also hook up your HD television to the laptop’s HDMI output.

Connecting to Internet, you have two options: either the 802.11ac WiFi + Bluetooth 4.0 card or the RJ-45 port using wire.

Even though it’s a 15-inch model, there’s no optical drive, so you must use external DVD drive if you need discs. The SD/MMC card reader might be handy too, but only if your files reside on memory cards.

The webcam supports 720p resolution, you can shoot some OK-quality YouTube videos with that or chat with your pals on Skype.

Are there other noteworthy things?

Lenovo Flex 3 15 (80R40006US) is quite lightweight for a 15.6 incher, it weighs 4.6 pounds while these models are often 5+ pounds. Also, somebody commented the 3-cell battery lasts long, but I don’t know if you’d get more than four or five hours.

If I recall correctly, the keyboard is not backlit here. A dedicated numpad is available.


Let’s start with the obvious strong point, the beefy Skylake-processor. It’s not only new architecture, but also one of the Intel’s flagship, the i7 series, so quite serious processor performance can be expected. Also 8GB memory will help with keeping programs running smooth. Too bad Lenovo Flex 3 15 (80R40006US) has no solid-state drive, only a hard drive, although that can be swapped to SSD if you know what you’re doing. The Full HD screen will turn into a tablet mode, surely useful for many on-the-go people. As usually, gaming performance is the weakest link here, but for non-players this setup should offer decent value and lag-free environment with most software.
