Lenovo's solar-powered Yoga concept laptop is such a good idea, I'm frankly shocked nobody's done it already

What if your laptop could get a full hour's worth of charge simply by leaving it in sunlight for 20 minutes? That's the promise of Lenovo's latest concept laptop, a Yoga model featuring a photovoltaic solar panel on the rear of the screen, converting light into charge for the laptop's battery.
I've seen a lot of great concept devices from Lenovo and other laptop makers at events like MWC 2025, and I'm usually pretty excited about them. So let me be absolutely, unequivocally clear about this one:
THIS RULES.
I'm serious. To be honest, I can't believe it took this long for a tech company to strap a solar panel to the back of an ultrabook. We need more of this. It feels like such a straightforward idea; naturally, the Yoga Solar PC can be charged conventionally via a cable, but just being able to close the lid and let it soak in the solar rays is brilliant - and basically ensures that you'll never be stranded without any charge again (unless it's the middle of the night, I suppose).
I can't be the only one who's gone on a trip or even just off to work, only to find that I've forgotten my laptop charger. Thus begins that stressful game of watching the battery life tick down, turning on efficiency mode, lowering the brightness, and praying.
But with Lenovo's Solar Yoga? I could just leave it on a windowsill for an hour while I have lunch, and come back to a freshly-charged battery.
It's also just a general triumph of eco-friendly engineering. The solar panel on the rear of the display (which, incidentally, doesn't appear to make the laptop noticeably thicker than Lenovo's other Yoga ultrabooks) offers an energy conversion rate of more than 24%, which is among the very best you'll see in any type of photovoltaic solar cells.
Lenovo also designed a 'Dynamic Solar Tracking system', which continually monitors the influx of electricity and adjusts the laptop's battery consumption to prioritize the solar energy to better preserve your battery life.
Solar-powered devices aren't a new thing, of course - fellow laptop manufacturer Acer sells a foldable 200W solar panel that you can hook up to a power bank, ideal for charging your devices when you're out in nature (or in a Mad Max-style apocalypse). But the Yoga Solar PC is the first ultrabook in the world with a fully-integrated solar power solution - and even though it's just a concept right now, it's one that I seriously hope makes it beyond the prototyping phase.
Having handled the device in person at MWC, it certainly looks and feels like it could be retail-ready. I can practically picture myself taking this bad boy camping, or even just down to the cafe.
Alright, okay, as much as I love this, I will admit that there are some potential stumbling blocks to this sort of tech being widely implemented in our laptops. For starters, solar panels aren't exactly the most durable things in the world - and I have to imagine that replacing an integrated panel like this would be a costly and difficult affair. Having a laptop with glass on the outside does feel a little bit like a recipe for disaster. Drop it once, and it might be game over.
Heat buildup also feels like a natural problem here. After all, you generally don't want your laptop to be too hot. But surprisingly, Lenovo had the Yoga Solar PC sitting under a bright lamp on their stand at the expo (presumably for hours at a time), and while the back panel itself was a bit warm to the touch, the rest of the laptop didn't feel hot at all. In fact, I'd be willing to bet that a metal exterior lid would probably cook your laptop more if you left it out in the sun.
Lastly, I suspect that if it were to make it to general production, the Yoga Solar PC would be very expensive. I've looked into getting solar panels installed on my house - and sure, this is just one solar panel, and it's a lot smaller, but it's also part of the laptop chassis rather than a standalone item - oh, and these Yoga laptops aren't exactly bargain-basement hardware to begin with.
Still, as someone who enjoys a good foray into the great outdoors, I think this proof-of-concept is a fantastic idea and I'd gladly throw money at Lenovo to own one. A laptop that's more eco-friendly and can save my bacon if I forget my charger? Sign me up.

Pokemon Scarlet and Violet's Switch 2 update footage shows the "notorious frame drop lake" running at 60fps, and fans say it might be "the best possible advertisement" for the new console
When you buy through links on our articles, Future and its syndication partners may earn a commission. The Switch 2 is officially out tomorrow, and with it, Pokemon Scarlet and Violet are getting a free update to improve their performance on the new console, with improved draw distance to load in even more wild Pokemon, as well as a boosted frame rate, finally bringing the adventures to 60fps. Considering how notoriously poorly Scarlet and Violet run on the original Switch – with problems like frame drops and stuttering still an issue over two years since launch – this is a massive deal, and the first gameplay footage and extended preview looks shown ahead of release have fans in a frenzy. Not only does everything look buttery smooth, but it remains that way even when embarking on Casseroya Lake. If you've spent any time at all in Scarlet and Violet's Paldea region, you'll know why this is a big deal. While far from the only location in the games to experience performance issues, it's largely considered one of the worst – stuttering and considerable frame rate drops while traveling across the water are commonplace. Or, at least, they were on the OG Switch, because Nintendo has jumped at the opportunity to show off what exploring the lake looks like now. As one stunned fan puts it, "the Casseroya Lake footage literally made me get up and stare at the screen like a 60-year-old father witnessing his football team score a goal on TV." Another adds that "showing the notorious frame drop lake at a crisp framerate was such a power play," while one fan argues that "this is the best possible advertisement they could have done for the Switch 2 oh my god." Again, it's not just a frame rate boost, as improved draw distance means a lot more wild Pokemon now populate the screen than ever before (potentially a huge boon for shiny hunters, might I add). Former Pokemon world champion Wolfe "Wolfey" Glick suspects that "if you tried to put that many Pokemon in the lake on my Switch from 2017 I think it would actually explode." All of these reactions were to the few short seconds of footage posted on the Nintendo Today app earlier this week, but since then, the owner of Pokemon news site Serebii, Joe Merrick, has shared even more from a preview event. His footage takes things to the next level, because that 60fps apparently remains consistent even in the rain, folks. "It is so beautiful," Merrick adds. It's just one day to go now before the Switch 2 is out and we can all try Pokemon Scarlet and Violet's update for ourselves – from what we've seen so far, it looks like there's never been a better time to explore Paldea.

Super Smash Bros. Ultimate's Nintendo Switch 2 journey isn't going too smoothly as Nintendo asks "please avoid using Mii Fighter in online play as much as possible"
When you buy through links on our articles, Future and its syndication partners may earn a commission. Nintendo Switch 2 has a ton of free updates available for existing Switch games, with a bunch of first-party Nintendo games getting the rub (especially Pokemon Scarlet and Violet, which desperately needed it). While Super Smash Bros. Ultimate is among the games that run better, it comes with an unexpected downgrade. Twitter user OatmealDome noticed on the US Eshop page for Super Smash Bros. Ultimate that the game is listed as "Supported – Game progression may be affected in portions of the game" for Switch 2. When you look for more info, it turns out there's not a progression issue; it's actually just that Mii Fighters are not working as they should. On the store it says, "In online play, when a Switch 2 player and Switch player have been matched, if someone is using Mii Fighter, the match may end immediately," and because of this Nintendo asks that players "please avoid using Mii Fighter in online play as much as possible." So while Mii Fighters do still work online on Switch 2, it's only if you face someone else playing on the new system. Not only are Mii Fighters having trouble in online crossplay, but Nintendo also notes, "When creating or editing and saving a Mii Fighter, the thumbnail image showing the Mii Fighter may not appear correctly." With the solution being a simple "This may be improved by saving it again." Nintendo hasn't explained why this happened, although it could be a compatibility issue stemming from the fact that Mii characters are now genderless on Switch 2, I don't know why that would matter when the gender doesn't matter in Smash, but that could have caused the issue. Regardless, Nintendo says that "This is planned to be fixed in the near future," so you can have your Hank Hill vs Sans Undertale brawls online once more. Street Fighter 6 sees Capcom follow the road Nintendo abandoned in Animal Crossing by adding a collection of stone-cold NES bangers.

As fans reject Switch 2 game-key cards, former Nintendo marketing leads say it's unlikely that physical games will ever "100% go away," because "they realize the importance of that"
When you buy through links on our articles, Future and its syndication partners may earn a commission. In the buildup to the launch of the Switch 2, not everyone has been filled with pure, unadulterated hype. A lot of people are seriously unhappy about the new game-key cards – a strange blend of physical and digital games that are being offered as the physical version of many (but not all) upcoming Switch 2 games, which former Nintendo marketing leads Kit Ellis and Krysta Yang have been discussing in their latest video. Game-key cards give users a full download of a game rather than allowing them to simply play it right out of the box, which has prompted concerns about game preservation, and generally hasn't been met particularly warmly by those who value physical media. Former Nintendo Minute hosts Ellis and Yang – who previously served as Nintendo of America's former director of social media marketing and original content and senior manager of creator relations and original content, respectively – have now shared their own thoughts on game-key cards, and offered some extra insight into Nintendo's potential thought process (below). To do so, they also spoke to another former Nintendo employee, who's not named in the video, but is apparently someone who worked on the company's retail team – specifically on the program that saw full game download codes sold on eShop gift cards in physical stores. Game-key cards, Ellis points out, can be seen as an "extension" to this idea. "What they had to say was, you know, even going back to the [gift] cards that you can get now, Nintendo really wanted a physical representation of a digital product in a retail store," Ellis explains. "Which makes sense, because Nintendo really values the retail channels, more so than a lot of other gaming companies." Furthermore, he mentions that the original game download gift card idea "was really widely adopted within the company, nobody was really questioning it, it was like 'Yeah this this seems like a great idea for us to kind of have it both ways.'" Yang notes that "they make so much more money off of the digital games," so "of course they're going to be looking at other solutions to kind of fill that gap, or even try to transition people over to an all-digital world." Interestingly, Ellis notes that "nobody really had very high expectations" for the gift card games, "but it went on to become a very popular program," and it certainly wasn't rejected by consumers. "That obviously gave them the confidence of like, 'Alright, something like this, this is actually maybe more in line with how people are getting things now, want to buy things, want to use things, than maybe we thought.'" But if game-key cards do sell well, what could this mean for the future? Well, the former employee Ellis and Yang spoke to says we shouldn't rule out the idea that some first-party Nintendo games could eventually get the same game-key card treatment, rather than getting regular physical cartridges. However, one key point that the three ex-Nintendo staff agree on is that it's highly unlikely the company is looking to phase out physical games entirely. "This person was also very clear in saying like there is going to be some form of physical," Yang adds. "The physical nature of video games is not something that's going away, and Nintendo is not going to take that away. They realize the importance of that." Ellis later adds, "I can't see the physical games vanishing completely," while Yang says we'll have to "see this initial batch of sales" and how they might "inform the future decisions," but "I don't think that physical is ever going to 100% go away, I don't think Nintendo will ever do that. "Talk about someone that knows their audience, they absolutely understand the audience, that their most dedicated audiences that just want this because they have this emotional tie to their brand, and they want to cultivate that. So I don't think that they're going to go out of their way to, you know, sever that bond." Looking for more Nintendo Switch 2 news?
