Lenovo IdeaPad Slim 3x review: Incredible battery life has never been so affordable
Finding a budget laptop that offers good value for your money can be a real challenge, especially if you're not sure what you should and shouldn't compromise on. The IdeaPad Slim 3x is a great example of how budget laptops can hit an affordable price and still offer great performance in key areas.
Despite costing well under $1,000, the IdeaPad Slim 3x impressed me with its outstanding battery life, lasting over 16 hours in our tests. With a snappy keyboard, roomy 15-inch display and relatively low weight, it's a great buy for students and casual users. If you can find it on sale, the IdeaPad Slim 3x is a steal.
Of course, it's not perfect. There are a few drawbacks you should consider before buying, but if you're searching for an affordable laptop that will last all day, the IdeaPad Slim 3x is a great choice. It's one of the best laptops for battery life we've tested this year and one of the best Lenovo laptops you can get on a tight budget.

The IdeaPad Slim 3x offers a lot of value for well under $1,000, especially with its outstanding battery life. It also boasts solid performance for the price and a fantastic keyboard.
By far the biggest strength of the Lenovo IdeaPad Slim 3x is its incredible battery life. It lasted 16 hours and 29 minutes in our battery life test, which is far more than enough for a full day at work or school. Battery life that long is especially impressive for a budget laptop like this one.
I wasn't surprised the IdeaPad performed so well in this particular area considering Snapdragon-powered laptops tend to be battery life all-stars. Given the price this IdeaPad really punches above its weight class, outlasting much pricier alternatives.
For instance, the Lenovo Yoga Slim 7x, one of my personal favorite laptops, only lasted 14 hours and 14 minutes on our battery life test. Granted, it has a more powerful processor, but if battery life is your top priority, the more affordable IdeaPad Slim 3x could be the better buy.
In contrast, the Acer Aspire Go, which is a similarly budget-friendly laptop, only lasted 10 hours and 15 minutes. It just goes to show, the IdeaPad Slim 3x offers a uniquely long battery life in the sub-$1,000 price range.
The IdeaPad Slim 3x could have scored a bit higher on our performance tests, but it didn't do poorly either—especially considering the price.
With a Geekbench 6 multi-core score of 10,505, the IdeaPad is powerful enough for basic everyday tasks like web browsing and word processing. You could probably get by with some minimal photo and video editing, but expect slow rendering and exporting.
On the other hand, if you're a student or you're looking for an affordable laptop for casual use, the IdeaPad Slim 3x is definitely up to the task. I had a good experience using it for tasks like writing, watching Netflix and replying to emails.

The IdeaPad Slim 3x is in a sweet spot among budget laptops, as well. It's a killer deal if you can find it on sale, but even at the full $749 price it offers better bang for your buck than laptops at the low end of the budget range.
For instance, the Acer Aspire Go 15 costs just under $300, which might sound like a steal—but its Geekbench 6 score is barely half of the IdeaPad Slim 3x's score. There's a much smaller gap between the IdeaPad Slim 3x's performance and that of the pricier Acer Swift 14 AI.
I often love the keyboards on Lenovo laptops and the IdeaPad Slim 3x is no exception. This might seem like a little thing, but if you're planning to use your laptop for tasks like writing, replying to emails, or coding, a great keyboard can make or break your experience. The IdeaPad Slim 3x offers a stellar keyboard at a budget-friendly price.
On the Monkeytype typing test I scored 96 words per minute with 97% accuracy, which is a bit above my personal average and just goes to show how swift and snappy this keyboard is. It also includes a full number pad, which can be really convenient for programming or filling spreadsheets. I appreciate that Lenovo didn't slip the power button into the keyboard, too (it's located on the right edge of the keyboard deck).
While I had a good overall experience with the IdeaPad Slim 3x, it's not perfect. There are a few drawbacks you should know about before making this your next laptop, including display quality, speaker volume, gaming performance and potential issues with app compatibility.
The display is one of the biggest drawbacks of the IdeaPad Slim 3x. Unfortunately, that's not uncommon in budget laptops. The display isn't bad, but it isn't outstanding, either. If you need a laptop primarily for tasks like graphic design or photo editing, you may want to choose something with higher display scores, like the Acer Swift 14 AI.
The IdeaPad Slim 3x sports a 15.3-inch 60Hz IPS touch display. It scored 48.4% on our DCI-P3 color gamut test and had an average brightness of just 296 nits. Even for a budget laptop, those scores are pretty low.

I noticed that low brightness while watching Stranger Things, which has a lot of dimly-lit scenes that didn't show up well on the IdeaPad. However, the matte finish on the display at least minimized reflections, which is nice. Text and well-lit content also looks fine, so the lackluster display might be a non-issue for some people.
The IdeaPad Slim 3x is by no means a gaming laptop. If that's what you're looking for, your options will be pretty limited in this price range, but a handheld gaming PC could be a good alternative.
Considering it's running on Qualcomm Adreno integrated graphics, I wasn't surprised by the IdeaPad's disappointing graphics performance. It scored 3,262 on the 3DMark Fire Strike benchmark and averaged just 21 frames per second in Sid Meier's Civilization VI: Gathering Storm.

To put that into perspective, the Acer Swift 14 AI, which costs just a few hundred dollars more, scored 5,720 on the 3DMark Fire Strike benchmark, but also averaged 21 fps in Civilization VI. The Acer Aspire Go 15 scored far lower, though, with just 1,928 on the 3DMark Fire Strike benchmark and a meager 12.3 fps in Civilization VI.
You're unfortunately just not going to get outstanding gaming performance on a budget laptop. Handheld gaming PCs offer slightly better performance for around the same price as these laptops, but if you're looking for something that can breeze through AAA games, you might want to save your money for a proper gaming laptop.
While it isn't necessarily a deal-breaker, I wish the speakers on the IdeaPad Slim 3x had a higher max volume. I rarely have to crank up the speakers when testing laptops, but I had to turn up the volume to 100% while watching Stranger Things on the IdeaPad. Even then, quieter scenes were a bit hard to hear clearly, especially with background noise like an air conditioner.
The speaker quality is fine, especially considering the price, with a decent balance of mids, highs, and bass. It's just a bit difficult to hear since the volume doesn't go as high as some may prefer, so you might want to keep a pair of headphones handy with this laptop.
While the IdeaPad Slim 3x can be a great sub-$1,000 laptop, it's worth noting that the Arm-based processor can present issues. This isn't unique to the IdeaPad Slim 3x, but rather a larger concern with Snapdragon-powered laptops.
Since they use a different type of processor architecture than Intel or AMD laptops, some apps aren't compatible with them, such as certain games and Adobe apps. This will likely improve over time as app developers expand support for Snapdragon chips, but it's just something to be aware of before buying.
With that said, if you're looking for a budget-friendly laptop and you're between the IdeaPad Slim 3x and a Chromebook, many of which go for this price or less, you would probably be better off with the IdeaPad since it's compatible with the majority of Windows apps. Chromebooks, in contrast, are limited to mainly apps on the Google Play Store.
While it isn't a perfect laptop, the Lenovo IdeaPad Slim 3x offers fantastic battery life and solid performance at a price that's tough to beat. If you can find it on sale, it's a serious bargain. This laptop would be an especially good pick for students and casual users, but probably isn't the right choice for power users and gamers.
If you're looking for a sub-$1,000 laptop that will easily last all day on a single charge, the IdeaPad Slim 3x could be perfect for you. Its battery life is impressive enough that it outweighs less significant drawbacks like a lackluster display and quiet speakers. It's hard to find battery life this long at such a low price, so that alone makes the IdeaPad Slim 3x stand out.
With that said, if you're looking for a budget laptop for gaming, you would be better served with a handheld gaming PC since graphics performance is not the IdeaPad's strong suit. Depending on your needs, you may also want to double check that your must-have apps are compatible with Snapdragon-powered laptops.
Those drawbacks might be deal-breakers for some, but if battery life and price are your top concerns, the IdeaPad Slim 3x could be the perfect choice.

Lenovo 15.6″ Touchscreen Laptop (8GB RAM, 256GB SSD) Is Such a Steal, You'd Think It's Refurb but It's New
Lenovo is known for making sleek powerhouses, and the IdeaPad lineup is especially good at delivering just that. If you've been thinking about picking one up, now's a solid time. Best Buy is offering the Lenovo 15-inch IdeaPad 1 touchscreen laptop for just $330 – that's $250 off the usual price. This is a more recent version of the IdeaPad 1 line with refreshed internals and some new, smart additions and with a discount this massive, we're definitely calling it a steal. See at Best Buy The laptop flaunts its impressive 15.6-inch full HD touchscreen display featuring an 87% active screen-to-body ratio. Sprinkle in 300 nits of brightness alongside a wider viewing angle with the IPS panel, and you've got yourself a screen that delivers great visuals while also being easy on the eyes, both indoors and outdoors. Streaming, browsing, or multitasking – it holds up well in all use cases. And since you can't really call a laptop powerful without solid internals, Lenovo backs this one up with the AMD Ryzen 5 7520U quad-core processor. It's paired with 8GB of LPDDR5 RAM and a 256GB SSD, enough to handle all your day-to-day work and play. Store and access all your files, media content, and games without a problem. Video calls get better, too. The 720p webcam gives you detailed, clear visuals, while the Smart Noise Cancelling feature minimizes background noise. There's even a privacy shutter because, yes, we take our camera paranoia seriously. Multitaskers getting curious about the battery – good news. The battery is designed to last up to 9 hours, which means an entire day of work. There's support for rapid charge as well, so 15 minutes of charging gets you around 2 hours of use, which is great for those hectic days when you're on the go and don't have time to sit near an outlet for long. Speaking of being out and about, carrying the laptop around won't weigh you down. At just 3.47 pounds, it's a reliable, no-fuss travel companion. IdeaPad 1 runs on the ever user-friendly Windows 11, and supports Copilot. The experience is made even better with Wi-Fi 6, which offers a strong internet connection. There's a lot more to like about the IdeaPad 1. It packs serious power into a slim frame that's easy to carry. This deal brings the price down to just $330, but it might not be around for long. We recommend jumping on it while you can, since we likely won't be seeing another discount this massive before Black Friday. See at Best Buy

Screw Foldables: Lenovo's Rollable ThinkBook Proves There Are Better Uses for Flexible Screens
With a buzz and a whirl, my laptop begins to unfurl. In less than six seconds after the press of a button, my petit 14-inch ThinkBook stands erect over my desk with a taller 16.7-inch display. There is literally nothing else like Lenovo's ThinkBook Plus Gen 6 Rollable, and that's partially why it costs a whopping $3,300. And you know what? There are few things cooler in laptop world than watching your screen expand from its original size. When you're dropping a hefty chunk of change on a laptop of this size, its benefits need to outweigh any tradeoffs. As cool the ThinkBook Plus Gen 6 Rollable is, when you actually use it, you'll find the joy of having a towering screen is actually one of its more annoying flaws. Lenovo ThinkBook Plus Gen 6 Rollable It's an enormously expensive laptop with a limited gimmick. But, hey, it's the most-usable way to bring a larger screen on the go. Pros Cons Normally, these kinds of 'concept' devices never leave the lab. When they do, companies bring them out for journalists and influencers to fool around with before being whisked off to gadget Elysium. Lenovo deserves credit for being ballsy enough to bring the ThinkBook Plus Gen 6 Rollable to market. After all, how will we know if something may become a game changer unless we regular folk have a chance to play with it in our plebeian hands? I'd love to encourage innovation, but a rollable device that costs more than two laptops combined needs to meet or beat what's expected from both a 14- or a 16-inch laptop, no matter which way up the screen is facing. At nearly three times the cost of other lightweight laptops, the Rollable ends up feeling weirder and occasionally more limited than a traditional device despite its neat party trick. Despite its unique mechanism, the ThinkBook Plus Gen 6 Rollable houses a similar kind of screen you find on many foldable phones. These flexible displays are way thinner than the ones on other laptops, which means they can twist, bend, or—in this case—spool out several inches from the laptop's main body. There have been multiple attempts at folding laptops, including Lenovo-made devices like the ThinkPad X1 Fold 16. The Rollable feels much more like a traditional laptop—and that's to its benefit. It still functions like a laptop no matter if you're using the 14- or near-17-inch mode. Either way, the OLED panel comes with all the benefits of organic light-emitting diode screens with self-emitting light, including a high color accuracy and deep, inky blacks. The laptop even packs Dolby Vision HDR for better contrast when you're streaming your favorite shows on Netflix or Disney+. Just know the taller screen won't let you watch content much larger than usual in its normal 9:16 aspect ratio. At the office, I prefer to work on widescreen monitors over a longer, portrait-style display. Then again, there are plenty of coders or writers who like to scroll less. There's nothing better than getting to read through an article without needing to jump to the trackpad. It also allows for multiple windows stacked on top of each other. Windows 11 already has a tiling system that makes it easy to put your apps where you want them. For some reason, Lenovo provides yet another tiling app through the device-specific software called ThinkBook Workspace. The app opens automatically when you unfurl the screen. If you use that app's specific tiling feature, it places a black bar between each app, and if you want that screen real estate back, you have to close the app. The ThinkBook Workspace includes a sometimes-handy 'Smart Copy' mode to access all your copy and pastes from your recent clipboard. It takes a little too long to load, considering most browser extensions with the same capabilities are near instantaneous. Workspace is necessary for the Rollable due to some apps not supporting the abnormal aspect ratio. But as I found out, it also gets increasingly annoying the more you interact with it—like a rat-catching feline who tends to leave a furball on your bedspread every night. Even if you would rather do without, Workspace is not something you can easily remove through settings or the Control Panel. I gave up, and just let it be. At first, it felt very strange to go a full workday staring at a laptop screen without any bottom bezel. When rolled out, the ThinkBook Plus Gen 6 Rollable sports wide bezels on top and thinner ones on the bottom. Laptop purists who demand the same size bezels all around may balk at how it looks, but it's the screen that counts most, and what's here looks very, very nice. That's not to say there aren't many strange considerations about the ThinkBook Plus Gen 6 Rollable you need to take into account. The screen doesn't tilt any further back than around 110 degrees, which—depending on the angle of your body and your sitting position—may not offer the best screen experience. The laptop won't roll out unless it's at least around 90 degrees open. If the screen is rolling and you start to fold the laptop lid, the mechanism will stop and the laptop will scream at you until you tilt it back to the correct position. You can't choose to stop the rolling mechanism while it's going. So while the laptop is technically more versatile than your typical thin and light, you won't be able to use it like you could any laptop with a screen that stays put. The big problem with other foldable laptops is that the need for the hinge and slim body limits the space these devices usually have for larger batteries. Without enough space, laptop makers can't include more powerful processors, RAM, and all the other specs that would push the performance you need on a portable big-screen device. I experienced this lack of performance firsthand on devices like the $5,000 HP Spectre Fold and Lenovo's own $2,500 ThinkPad X1 Fold 16. The end result is a device you don't actually want to use despite being more portable. The ThinkBook Plus Gen 6 Rollable doesn't have that problem. It's packing an Intel Core Ultra 7 258V CPU and the integrated Intel Arc 140V graphics. It contains all the expected specs, such as a 1TB SSD, 32GB of LPDDR5X RAM, and a 66Wh battery. The Core Ultra Series 2 chips made their debut last year, and they're still a relatively strong option on small, portable machines. I found the Intel Core Ultra 258V behaved as well as can be expected when the ThinkBook Plus Gen 6 Rollable was plugged in on performance mode. There's no real performance loss between using the device in a 14-inch or 16-inch mode, at least when it's sucking down power from an outlet. The Intel Core Ultra 258V keeps pace at or just below chips like AMD's AI 7 350 in CPU-heavy tasks with the device firing on all cylinders. For graphics tasks, the ThinkBook Plus Gen 6 Rollable still won't be your laptop of choice even with Intel's built-in Arc 140V GPU. If it's benchmarks you want, the M4 chip found on Apple's MacBooks still wins out. It's when using the ThinkBook Plus Gen 6 Rollable off battery power that the larger screen added more than a few hiccups. I had positioned two Chrome browsers on top of each other with around a dozen tabs each, and the PC would occasionally glitch, blurring text on the southern part of the screen. Other times, one of the Chrome windows blacked out randomly. The ThinkBook Plus Gen 6 Rollable also leads to strange circumstances with some apps. This isn't a laptop meant for gaming, but I decided to load a few on it for kicks. Lightweight games like Hades defaulted to 2,000 x 2,352 resolution and sat in the middle of the 16.7-inch screen. Tactical Breach Wizards maintained the same resolution but extended the display from end-to-end. I don't know how many games support this extra-long aspect ratio, but I've never experienced anything quite like it on a laptop. The latest Intel chips are more efficient than previous-gen ones, though that doesn't mean laptops like the ThinkBook Plus Gen 6 Rollable are truly all-day devices. Even without running the motors to winch open the screen, I only ever got around 5.5 hours of battery life, at most. Naturally, with the screen unfurled to its full height, the battery will necessarily drain faster than using the 14-inch screen. If I were limiting use and running on battery-saving mode, I could push the device to last a full day's work. But why would I, considering this is a device made for multitasking beyond anything else? Thin and light laptops have been trending thinner and lighter, but when clammed up, the ThinkBook Plus Gen 6 Rollable feels like a device from another time. It slides effortlessly into a backpack's laptop sleeve and you can carry it around with one hand, though not as easily as you may want to thanks to its 3.72 pounds and bulky chassis. What that extra heft implies is that the device is supremely sturdy. There's no keyboard flex to speak of. My palms felt like they were rising on a bed made of inch-thick aluminum. That build quality also translates to other parts of the device, though I can't speak for how long the display's motors or flexible screen will last long term with constant scrolling, daily. It survived more than a week's worth of back and forth to the office, but I can't say what will happen in several months' time. If you're spending over $3,000 on a laptop, you want it to be top of the line in every other way than just the screen. It's a good thing the keyboard offers a smooth and responsive typing experience. The haptic trackpad has a similar high-quality responsiveness, where every click has the same satisfying feeling of popping bubble wrap. The design seems copied straight from Lenovo's Chromebook Plus 14 that I reviewed last month—and yes, that's a good thing. It's the kind of low-profile keyboard and trackpad I could tap all day long. For its size, the ThinkBook Plus Gen 6 Rollable is packing hefty speakers. The twin Harman Kardon speakers blast sound out both the left and right sides of the laptop. It's not enough to fill a room or shudder your bowels with extreme bass, but they can get relatively loud. The audio on the average Netflix movie sounds clear enough that I wasn't immediately reaching for a pair of quality earbuds or headphones. Even with an extended display, I still felt the need to connect an external monitor whether I was working in the office or at home. In this kind of setup, the 16.7-inch screen is a godsend for a writer like me. At the same time, the Rollable is only packing a pair of Thunderbolt 4 USB-C ports on the left side of the device. You'll end up needing a port dock close at hand. Considering its thick size, you would expect to find an HDMI port or more I/O, but the Rollable's thicker body is made to house the rolling screen apparatus. Companies keep trying to find ways to make laptop screens bigger without expanding the size of the laptop itself. We've seen and tested our fair share of multi-display bolt-ons, like the Xebec Snap, the Aura Triple Laptop Display, or Lenovo's separate clip-on concept monitor. When you lay out the long line of failures, Lenovo's ThinkBook Plus Gen 6 Rollable is the best attempt at extended screens yet. If it weren't for the annoying software and compatibility issues, I would be left with a black hole where the money in my wallet used to be. The only thing that could fill that hole would be the tenuous sense of optimism that the screen or rolling mechanism would continue working for months or years down the road. I could only keep that upbeat attitude going for so long. The thought of my $3,300 laptop breaking is enough to have me roll up on my back with my legs and arms as erect as the ThinkBook Plus Gen 6 Rollable, like a cockroach about to croak.

Lenovo Clears Out 4.8-Star All-in-One Desktop at 71% Off for Back-to-School (24-Inch, 32GB RAM, 1TB SSD)
Figuring out what you need from a PC is a big ask. It's not just stats to think about, but the size of the device, what you actually want it for, and that's to say nothing of all of the peripherals. It'd be easier if you could just get it all in one place and just enjoy a desktop PC without all of the hassle. Even better if you can do that and save some money as well. Well, right now you can pick up a Lenovo 24 All-in-One Desktop Computer for $600, which is 71% off the listed price. That's an absolutely incredible discount, but that means it's also not likely to last very long. In fact, as this is a limited-time deal, we've got no way of knowing when the deal will end. See at Amazon The advantage of a device like this is that you don't need to worry about where to put it, because it's all in one place. You can just plop this on a desk and you're good to go. Not only that, but monitors can be pretty pricey, and this takes that cost out completely. It's just one less hassle than you would have otherwise, and making life a little bit simpler is always nice. This model has a 23.8-inch full HD screen with anti-glare and a good range of colors. It's got plenty of viewing angles as well, which makes it really good for meetings or showing off creative endeavors. The screen, of course, is just part of the puzzle here though. The specs it has in it include a mighty 32GB of RAM and a 1TB SSD. This means that not only can you multitask really easily, but you'll have no issues running your favorite programs and keeping your productivity up. The SSD means that you'll also be able to store a huge number of projects, videos, photos, and more without having to worry about anything. It also has a good number of ports to make sure you have no problem with the peripherals you do decide to commit to, and it has Windows 11 Pro as well. That's an awful lot of the price of $600, but this isn't a deal that's going to last for very long. So, if you do decide you want this to help you work, we recommend getting it quickly or you may end up missing out. See at Amazon
