In the ranks of convertible Chromebooks, the Lenovo Chromebook Flex 5 has among the least elegant name and the least elegant design. At 17mm thick and 1.35kg in weight, it’s actually slimmer and lighter than the Acer Chromebook Spin 713, but there’s something about the balance and 16:9 aspect ratio that makes it less satisfying to use in tablet form. Meanwhile, the Asus Chromebook Flip C436FA feels substantially lighter and goes even further than the Acer in its tablet-like appeal, and has a larger 14in screen to boot.

However, the Lenovo has some real points in its favour. It’s cheaper than both its rivals while matching the Asus on screen quality and beating both on performance, and we would argue that it’s the best of the three for overall usability if you’re planning to use your Chromebook primarily in laptop form.

The physical design might be more businesslike, but it’s still very functional, with the 13.3in screen folding back on Lenovo’s ingenious hinge to work in either tent or tablet modes. Only the lid is metal, with the body made of plastic, but Lenovo has done a great job of matching the colours and making it all feel like one unit. The bezels around the screen are narrow, bar the chunky one below the display, and the dark grey keys complete the styling – it looks more expensive than it is.

The Flex 5 may not be as svelte as the Asus, but it makes up for it with connectivity, fitting in a USB-A 3.1 port as well as the USB-C 3.1 ports you’ll find on either side. Lenovo has also placed a volume rocker and an on/off button on the right-hand side, which definitely helps when you’re watching films in tablet mode and want to quickly turn the volume up or down. It’s also one of the cheaper Chromebooks we’ve seen with Wi-Fi 6 (in a 2x2 MIMO configuration), not to mention Bluetooth 5.

The screen is another sure sign of a Chromebook that punches well above its price tag, with a 300cd/m2 maximum brightness, 99.1% sRGB coverage and a low Delta E of 1.96. Its gloss coating isn’t as reflective as the Acer’s, and with a Full HD resolution it’s impressively crisp and clear. The same can’t be said about the audio, though, which suffers from little bass, a harsh treble and a boxy, congested mid-range, so you might want to connect some headphones if you’re planning to either watch movies or play Stadia games.

Lenovo laptops – including its Chromebooks – tend to have good keyboards, and while the Flex 5 doesn’t have a ThinkPad-level effort due to a lighter feel, its 1.4mm travel and positive action mean that it’s still a treat to type on. The touchpad is nothing special in terms of size or materials, but it works pretty much flawlessly when recognising swipes and taps, multi-finger gestures or left and right clicks.

There’s nothing second-rate about the IdeaPad Flex 5’s performance, either. Equipped with a Core i5-10210U processor and 8GB of DDR4 RAM, it matched substantially more expensive Chromebooks in our benchmarks with scores of 958 and 3,458 for Geekbench 5’s single-and multi-core tests. That’s within touching distance of the HP Pro C640 and Dell’s Latitude Chromebook 7410 for single-core tasks, and ahead of both for multi-core operations. With a 128GB M.2 SSD rather than the usual eMMC flash storage, it’s also well equipped to handle Android apps and Linux applications at decent speeds.

What’s more, you won’t find yourself reaching for the charger too often because the IdeaPad Flex 5 doesn’t fall down when it comes to stamina. We didn’t quite make 12 hours before it ran out of power, but 11hrs 9mins should see you through the working day.

Overall, that’s what we like about the IdeaPad Flex 5 Chromebook. It’s neither the fastest nor the flashiest machine, but everything is designed and specified to give you a great, hard-working Chromebook at a very affordable price. So, if you’re looking for a workhorse that can handle a little entertainment on the side, you won’t find anything better for the money.
