This laptop has a customizable, color e-ink screen right on its lid

Lenovo has been experimenting with e-ink screens on its laptops for years, but this is the first one that has really caught my eye. On its new ThinkBook 13x Gen 4 SPE, which was shown off at CES 2024, you have a full “E Ink Prism” screen covering the entirety of the laptop lid.

E-ink Prism isn’t your typical e-ink though. It can present eight colors and combine them in whatever patterns designers want, and is claimed to “bridge the gap between traditional static materials and digital technology.” And that’s exactly the purpose it seems to have here.

Lenovo says the concept supports up to 1,000 different images, allowing you to personalize your laptop cover however you please. The company has four designs to show off, with one of them being a clock and another a “multisystem interaction.” The clarity and sharpness of the e-ink screen looks fantastic — not at all like the quality you might associate with the technology.

What’s more, the technology is supposedly ultra-low power, with Lenovo claiming it won’t impact battery life, even if the laptop is powered off.

Last year, Lenovo had the ThinkBook Plus Gen 4, which also had a e-ink screen on the lid that could be flipped around to the front using the unique hinge.

The technology is still in the “proof of concept” phase, but in this example, is being integrated on the ThinkBook 13x Gen 4. This is a super-slim and light 13-inch laptop, weighing just 2.2 pounds and coming in at only 0.51 inches thick. It features Intel Core Ultra processors, of course, and a 13.5-inch 120Hz display with a 2.8K resolution.

Lenovo says the laptop, with its 74 watt-hour battery, will get up to 21 hours of video playback and 11.4 hours of web browsing.

The laptop also supports the company’s Magic Bay solution on the top bezel to improve the camera or speakers. There are some new Magic Bay options the company is playing around with too, such as an additional screen or a cute robot face that winks at you.

Lenovo is also calling this laptop its first carbon-neutral product for the small business market, as it’s been certified by the British Standards Institution. The Luna Grey model is made out of 50% recycled aluminum.

But the E-ink Prism cover is definitely the star of the show on the ThinkBook 13x Gen 4. Lenovo hasn’t announced if or when it will be released, but the ThinkBook 13x Gen 4 itself will be available starting in the first quarter of 2024 with a starting price of $1,399.

Best laptops for back to school 2026 featuring Apple 2026 MacBook Neo

A laptop is probably the one purchase that'll have the biggest impact on the school year. It'll be there for lectures, late-night assignments, group projects, Netflix binges, and everything in between. The trick is finding one that fits both the workload and the budget. After narrowing down the options, these are the five laptops I'd actually recommend for Back-to-School, whether the priority is getting the most value, joining the Apple ecosystem, or investing in a machine that'll comfortably last through graduation.

These are the compact printers I’d actually recommend for back-to-school
From dorm room paperwork to instant selfie prints, there's a tiny printer for every need.
Computer Hardware, Electronics, Hardware

Everything is digital until the one professor who still wants a printed essay, or the lease you need to sign in ink, or the photo you want to stick on your dorm room’s wall. That's usually the exact moment you remember you don't own a printer anymore, and the nearest one is a library machine with a line out the door.

I looked at four compact printers that solve that problem without taking over your desk and breaking the bank. Two are built for documents, one is a proper all-in-one for actual home office work, and one has nothing to do with homework and everything to do with turning your camera roll into something you can hold.

Shopping for back-to-school? These are the webcam lights I’d actually turn on before a Zoom call
From a budget clip light to a proper desk setup, there's a webcam light here for every price.
Head, Person, Face

Between online classes, group project calls, and the occasional job interview over Zoom, your webcam will be doing a lot more heavy lifting in school than it ever did at home. The problem is that most laptop cameras are bad in low light, and a single overhead bulb or a window behind you turns every call into a game of "wait, can you see me okay?"

A good webcam light fixes that faster than moving your whole desk around. I picked five, starting with the most affordable and working up to the one that's genuinely overkill for a Zoom call but still worth knowing about.
