2-in-1 laptops are not “new” or “wow” anymore, but it doesn’t really matter. Some people still want such a convertible notebook, because who likes to have two separate devices if they can be conveniently put in one machine instead? Lenovo Flex 3 80JM002CUS is this kind of a laptop, sporting Core i7 processor and 8GB RAM in addition to the 360 degrees turning touchscreen. Below, you will find our thoughts if such a system would be a good pick or just something to stay away from…

General performance

Looking at the price you can see there are possibly many things you can do with Lenovo Flex 3 80JM002CUS. Then, after taking a look at the actual specifications, you are absolutely sure about that. The processor here is Intel Core i7-5500U, a dual-core Broadwell unit offering 2.4GHz clock speed with 3.0GHz turbo. It’s a low voltage model, not reaching the same ridiculously high performance than its power hungry brothers (like i7-4720HQ). Nonetheless, CPU Mark grade is still healthy 4000 – for example common 4th Generation Core i3s receive around 2500. The i7-5500U is a multi-use processor, very good for casual users with lightweight programs and also adequate for professionals working with complex applications.

The notebook features 8GB memory (DDR3L 1600Mhz if you’re interested about the technical side). It’s excellent amount for a 2015 laptop, more would probably mean an overkill. It looks like only one memory slot is available on the mainboard, thus you couldn’t upgrade the RAM even if you’d like to.

You’ll be able to store a lot of files on the 1024GB drive. To give you a real life example, you’d be able to put data equivalent to ca. 200 DVDs to that HDD. Of course, there’s a flip side to such a big drive, and that is the performance. A 5400RPM drive like this won’t start up Windows or your programs very fast. If you think that sucks, you can fix the issue yourself by replacing the default HDD with a solid-state drive.

Gaming in nutshell

Lenovo Flex 3 80JM002CUS works for gaming like any laptop with integrated graphics would: alright, if you’re a casual gamer happy with less eye candy. The graphics engine is Intel HD 5500. You can even play some of the heavyweight titles like GTA 5, but that would give playable 20-25 frames per second only with medium settings and 720p resolution. Some less demanding games, such as Minecraft, would however work much better: +50FPS with default settings.

About display

Lenovo Flex 3 80JM002CUS contains a 15.6-inch touchscreen display. Resolution is 1920×1080, panel type IPS, but the real specialty is the hinge: the screen flips 360 degrees, turning the laptop into a tablet in a second. Such a system can be very handy, but also remember it will be much bigger and heavier than a regular tablet.


There seems to be four USB ports in Lenovo Flex 3 80JM002CUS – two are USB 2.0, two support USB 3.0. HDMI-out is there as well, you can utilize that by plugging in an external monitor (like HDTV).

Optical drive is unfortunately something this unit does not have, you’d have to rely on an external drive if you needed access to discs. There’s however SD/MMC card slot available, that you’d be able to use with digital cameras and other memory card eating devices.

Connecting to Internet should be easy, the notebook features A/C WiFi + Bluetooth 4.0 combo card and 1000Mbps RJ-45 connector. There’s also 720p webcam available for some Skype chatting.

Other thoughts

The weight of Lenovo Flex 3 80JM002CUS is on the low side compared to regular 15.6″ laptop (4.62 vs. around 5 pounds). The 3-cell 45Wh battery seems to be a built-in one, replacing it yourself is not easy. It will last more or less 4 hours under light workloads.

Operating system is Windows 10 Home. The keyboard is backlit and features a 10-key pad.

Summing it up

Lenovo Flex 3 80JM002CUS is a decent (yet expensive) tool for people who value functionality. You can use the device as a laptop for the most part of the day, and when you feel the need, just turn the screen and now you have a tablet ready to rock. The Core i7 processor and his companion, the 8GB RAM, should make sure that practically any program will run without bigger issues here, and the 1TB hard drive takes a lot files before filling up. There are not many drawbacks I can see, if you have the money and need for this kind of 2-in-1, by all means go for this Lenovo.
