Lenovo IdeaPad Slim 3 review: A rare miss from Lenovo

The Lenovo IdeaPad Slim 3 is a 15-inch budget touchscreen laptop, and we tested a $769 configuration available through Costco. I’m generally a fan of Lenovo laptops, but this one isn’t up to the standard I expect from them. While this laptop does have a nice design and solid build quality, it feels like so many corners have been cut — and the price has crept up enough — that the resulting product isn’t a great deal. This is the kind of product that makes ‘budget’ feel like a warning, and here’s why.

Lenovo IdeaPad Slim 3: Specs

The Lenovo IdeaPad Slim 3 has an Intel Core 5 210H CPU. While this is an Intel Core (Series 2) processor, it’s based on last year’s Raptor Lake hardware rather than this year’s Lunar Lake hardware. That means you won’t find a neural processing unit (NPU) for Copilot+ PC features and other AI tasks here. You also won’t find the improved power efficiency and dramatically boosted integrated graphics Lunar Lake delivered here, either.

The design and build quality are nice, but the price of $769 just feels too high for a machine where nothing really shines.

Lenovo IdeaPad Slim 3: Design and build quality

The laptop’s design is quite nice. It’s made of plastic — no metal chassis here — but that smooth plastic feels fine and there’s nothing creaky or low-quality feeling here. In its “Cosmic Blue” color scheme, it’s a nice dark hue that has more of a blue scheme in the light. It’s a modern Lenovo design that looks a lot like higher-end Lenovo laptops.

The hinge feels solid and opens to 180 degrees if you want to lie the machine flat, although I need both hands to open the laptop. It’s a perfectly serviceable design. It doesn’t look cheap.

This being a budget-priced consumer laptop, there are a few popups right out of the box — but you can uninstall McAfee antivirus, for example, and dismiss the other notifications. Those help keep the price down. It’s annoying out of the box, but it’s fine.

Lenovo IdeaPad Slim 3: Keyboard and trackpad

The Lenovo IdeaPad Slim 3 has an okay keyboard complete with a number pad at the right — I like having that number pad on larger laptops like this one, but some people may prefer skipping the number pad. It has a backlight, too.

The keyboard feels reasonable. Lenovo laptops tend to have good keyboards, and this is comfortable enough, but it’s also a little mushy for a Lenovo keyboard. While typing, I notice the plastic around the keys pushes down into the chassis as I bottom out the keys. It contributes to that slightly mushy feeling. It’s fine for a budget laptop, but I eye that price and wonder whether this is truly in the budget price range.

The trackpad feels nice. It’s more to the left than it is on many laptops, but that centers it below the primary keyboard area. The surface is nice and smooth, but of course it’s plastic — a glass trackpad just feels smoother. The click-down action feels good to me.

Lenovo IdeaPad Slim 3: Display and speakers

The Lenovo IdeaPad Slim 3’s 15.3-inch 1920×1200 IPS display is the weakest part of the experience. At 300 nits of brightness, it’s on the dim side on paper. But the display feels unusually dim — and not just dim, but the colors feel rather dull. I cranked it up to 100 percent brightness and still feel like I want to have it brighter.

The anti-glare coating does work well. But a higher resolution would be nice at this size — or at least a panel with more vibrant colors and better contrast. The 60Hz refresh rate here is also rather low-end, but it’s the least of my concerns with this display.

This is a touch-screen laptop — the touch screen works well, of course. A touch screen is always nice to have.

The speakers are also lacking. They’re on the quiet side, and the audio quality is rather tinny. I listen to both Steely Dan’s Aja and Daft Punk’s Get Lucky on Spotify when I review laptop speakers. Both the instrument separation in Aja and the bass in Get Lucky were unusually bad for laptop speakers. While the build quality and design are good, this is a budget laptop through and through.

Lenovo IdeaPad Slim 3: Webcam, microphone, biometrics

The Lenovo IdeaPad Slim 3 has a 1080p camera with a physical privacy shutter — which is great to see. The webcam itself doesn’t feel particularly special — the colors feel washed out. Still, it’s a perfectly serviceable webcam if you need the occasional video meeting. I’ve seen people in surprisingly senior positions use much worse webcams in their meetings!

The dual-array microphones here don’t impress, either — they picked up my voice fine, but the sound quality wasn’t particularly great.

The Lenovo IdeaPad 3 slim has an IR camera for facial recognition with Windows Hello, so you can sign in with your face. This works well! And I’m pleased to see facial recognition hardware here.

Lenovo IdeaPad Slim 3: Connectivity

The Lenovo IdeaPad Slim 3 does have a decent selection of ports for a budget laptop. On the right side, this machine has a USB Type-A port and a full-size SD card reader.

On the left side, Lenovo includes a power connector (this machine doesn’t charge via USB-C, like many other laptops) along with a second USB Type-A port, an HDMI 1.4 out port, a USB Type-C port, and a combo audio jack. It’s nice to see HDMI out along with multiple USB Type-A ports and an SD card slot.

This machine supports Wi-Fi 6 and Bluetooth 5.2 — no future-proof Wi-Fi 7 or Bluetooth 5.4 here.

While this is certainly enough for many people, it all feels a bit low-end when so many laptops are shipping with support for Thunderbolt 4, HDMI 2.1 out, Wi-Fi 7, and Bluetooth 5.4.

Lenovo IdeaPad Slim 3: Performance

The Lenovo IdeaPad Slim 3 performs fine in day-to-day tasks like browsing the web, using Office apps, listening to music on Spotify (assuming you have headphones,) and using other typical Windows desktop apps. While the Intel Core 5 210H processor here isn’t a speed demon, it’s more than good enough for typical Windows desktop use.

As always, we ran the Lenovo IdeaPad Slim 3 through our standard benchmarks to see how it performs.

First, we run PCMark 10 to get an idea of overall system performance.  With an overall PCMark 10 score of 5,763, the IdeaPad Slim 3 comes a decent way behind more expensive laptops with high-end CPUs.

Next, we run Cinebench R20. This is a heavily multithreaded benchmark that focuses on overall CPU performance. Since it’s heavily multithreaded, CPUs with more cores have a huge advantage.

The IdeaPad Slim 3 produced a multi-threaded score of 3,270 here. The Intel Core 5 210H with its eight cores (four performance cores and four efficiency cores) didn’t produce big numbers on this multithreaded benchmark — which doesn’t represent real-world use unless you have a demanding and multithreaded CPU-heavy workload.

We also run an encode with Handbrake. This is another heavily multithreaded benchmark, but it runs over an extended period. This demands the laptop’s cooling kick in, and many laptops will throttle and slow down under load.

The Intel Core 5 210H in this machine finished the encode process in 2,330 seconds, which is nearly 39 minutes. That’s a long time — but again, this isn’t the kind of machine you buy if you’re looking to run intensive CPU-heavy workloads.

Next, we run a graphical benchmark. This isn’t a gaming laptop, but it’s still good to check how the GPU performs. We run 3Dmark Time Spy, a graphical benchmark that focuses on GPU performance.

Meteor Lake’s integrated Intel Graphics here really dragged this machine down. With a score of 3Dmark Time Spy score of 1,164, this is three to four times slower than modern laptops with Intel Lunar Lake’s Arc graphics hardware. If you want to play the occasional game or run a GPU-intensive app, this aging platform is a major drawback.

Overall, while the IdeaPad Slim 3 did a fine job of running typical desktop applications, its performance doesn’t shine. The multithreaded performance isn’t a big deal here, but the low integrated graphics performance hurts.

Lenovo IdeaPad Slim 3: Battery life

The Lenovo IdeaPad Slim 3 has a 60 Watt-hour battery, which isn’t particularly huge but is reasonable — Lenovo could’ve gone down to a 50 Watt-hour battery to save on cost.

To benchmark the battery life, we play a 4K copy of Tears of Steel on repeat on Windows 11 with airplane mode enabled until the laptop suspends itself. We set the screen to 250 nits of brightness for our battery benchmark. This is a best-case scenario for any laptop since local video playback is so efficient, and real battery life in day-to-day use is always going to be less than this.

The machine lasted for an average of 561 minutes — that’s nearly nine and a half hours — before suspending itself. That may seem like an impressive number, but it means that it has no hope of making it through an eight-hour workday in real use. The combination of the less power-efficient Raptor Lake hardware and a 60 Watt-hour battery life sees to that. But this machine looks less impressive because Intel, AMD, and Qualcomm have made huge strides in power efficiency since Raptor Lake’s release. This used to be normal. But by mid-2025, you can do much better.

Lenovo IdeaPad Slim 3: Conclusion

When I review laptops, I like to ask “Who is this for?”. Even if a laptop doesn’t make sense for most people, there’s usually someone who will love it. But when I look at the Lenovo IdeaPad Slim 3, I really don’t get it. The design and build quality are nice, and it offers reasonable desktop performance and a better-than-average port selection, unless you scrutinize the specs too closely.

But the price of $769 just feels too high for a machine where nothing really shines. If the display looked better or at least wasn’t so dull, I think I could see the argument for this machine. When I look at PCWorld’s list of the best laptops, I see both budget laptops that are much less expensive — and laptops in a similar price range that offer a better experience.

On the other hand, if you don’t need all that much from your PC and you find this on sale for less, it’ll do okay. But I can’t recommend the Lenovo IdeaPad Slim 3 at its retail price.
