Deliveries will generally be made within the timeframe of the selected delivery type after collection from point of dispatch and between major centers from Monday to Fridays. Next up is another synthetic graphics test, this time from Unigine Corp. Like 3DMark, the Superposition test renders and pans through a detailed 3D scene, this one rendered in the eponymous Unigine engine for a second opinion on the machine's graphical prowess. We present two Superposition results, run at the 720p Low and 1080p High presets and reported in frames per second (fps), indicating how smooth the scene looks in motion. For lower-end systems, maintaining at least 30fps is the realistic target, while more powerful computers should ideally attain at least 60fps at the test resolution.
Like some costlier notebooks, the IdeaPad 3i turns on when you open its lid rather than waiting for you to press the power button. The webcam has predictably soft-focus 720p resolution, but it captures relatively well-lit and colorful images without too much static. And talking of lists, be sure to take a look at T3's best lightweight laptops guide if you want a portable PC that doesn't weigh much.
Everything You Need, Nothing You Don't
Alternatively, you can also go for the Intel Core i5-1165G7 variant, which comes with GeForce MX450 GPU from NVIDIA.
After fully recharging the laptop, we set up the machine in power-save mode (as opposed to balanced or high-performance mode) where available and make a few other battery-conserving tweaks in preparation for our unplugged video rundown test. (We also turn Wi-Fi off, putting the laptop into airplane mode.) In this test, we loop a video—a locally stored 720p file of the Blender Foundation short film Tears of Steel—with screen brightness set at 50% and volume at 100% until the system quits. Limits:Limit 5 per customer. Offers valid from Lenovo in the US only. Lenovo may increase or decrease these limits, from time to time, for certain offerings. Battery:These systems do not support batteries that are not genuine Lenovo-made or authorized. Systems will continue to boot, but may not charge unauthorized batteries. Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and provides no warranties for failures or damage arising out of their use. Battery life (and recharge times) will vary based on many factors, including system settings and usage. measures relative graphics muscle by rendering sequences of highly detailed, gaming-style 3D graphics that emphasize particles and lighting. We run two different 3DMark subtests, Sky Diver and Fire Strike. Both are DirectX 11 benchmarks, but Sky Diver is more suited to laptops and midrange PCs, while Fire Strike is more demanding and lets high-end PCs and gaming rigs strut their stuff. To boot from a USB, hold F12 when booting and select your USB device from the text menu. To enter the bios, press F2 (or possibly DEL) when booting.
The Design: Mostly Generic Gray
Faulty/defective products after 14 days. (excluding all plasma LCD & LED televisions larger than 32-inch as well as all large appliances)
Then I shrunk the windows partition to make room to install Linux. I use Fedora, but any modern Linux should work. No surprises. Hardware drivers were all in the default repos. (The machine has an Intel WiFi 6 card and Realtek audio.) UL's PCMark 10 is our main benchmark, which simulates a variety of real-world productivity and content-creation workflows to measure overall performance for office-centric tasks such as word processing, spreadsheeting, web browsing, and videoconferencing. We also run PCMark 10's Full System Drive test to assess the load time and throughput of a laptop's storage.

Over on the memory, it is available with 8GB DDR4-3200 RAM and 256GB M.2 NVMe SSD storage. Fueling the device is a 42Whr battery. Rest of the specs Three further benchmarks focus on the CPU, using all available cores and threads, to rate a PC's suitability for processor-intensive workloads. Maxon's Cinebench R23 uses that company's Cinema 4D engine to render a complex scene, while Primate Labs' Geekbench 5.4 Pro simulates popular apps ranging from PDF rendering and speech recognition to machine learning. Finally, we use the open-source video transcoder HandBrake 1.4 to convert a 12-minute video clip from 4K to 1080p resolution (lower times are better). Mine has Windows 11 Home in it in S-Mode. In the box are instructions to get it into normal Windows mode.
Next is Maxon's CPU-crunching Cinebench R15 test, which is fully threaded to make use of all available processor cores and threads. Cinebench stresses the CPU rather than the GPU to render a complex image. The result is a proprietary score indicating a PC's suitability for processor-intensive workloads.
Verdict: Not Much to Complain About for the Price
We test Windows PCs' graphics with two DirectX 12 gaming simulations from UL's 3DMark, Night Raid (more modest, suitable for laptops with integrated graphics) and Time Spy (more demanding, suitable for gaming rigs with discrete GPUs).
Great Deal
