When buying a secondhand budget notebook, older models often cross your radar. Released back in 2017, the Lenovo Ideapad 520 15IKB arrived as a sleek aluminum-clad multimedia machine meant for students and daily office workers. Today, you'll find these units heavily discounted on the used market. But does this aging hardware hold up for everyday tasks, or will it leave you frustrated by endless lag?
The short answer: The Lenovo Ideapad 520 15IKB is still worth buying today, but only if it has an SSD and you plan to use it strictly for light web browsing, writing, and office tasks. Units shipped with a mechanical hard drive are painfully slow, and the integrated or entry-level NVIDIA graphics struggle with modern gaming or heavy video rendering.
Let's break down the hardware, performance hurdles, upgrade paths, and whether this machine deserves a spot on your desk.
Lenovo Ideapad 520 15IKB Core Specifications
Understanding how this machine performs starts with its core components. Lenovo offered several configurations of the 15-inch chassis, spanning 7th and 8th-generation Intel Core processors.
- Processor: Options ranged from the dual-core Intel Core i5-7200U to the quad-core i5-8250U (Kaby Lake Refresh).
- Graphics: Depending on the model, you either got basic Intel HD 620 integrated graphics or a discrete NVIDIA GeForce MX150 (2GB GDDR5).
- Memory: Typically configured with 4GB to 8GB of DDR4 RAM, where part of it is soldered directly to the motherboard.
- Storage: Shipped originally with either a slow 5400 RPM mechanical hard drive or a modest SATA/NVMe SSD.
- Display: A 15.6-inch 1920x1080 Full HD anti-glare screen, utilizing either TN or IPS panels depending on the exact sub-model.
Design and Build Quality
The 520 series marked a major design step up from older budget plastic laptops by introducing an aluminum lid and keyboard deck. This metallic finish gives the machine a rigid, clean aesthetic that resists flex around the palm rests. Weighing roughly 4.85 pounds (2.2 kg) and measuring around 22mm thick, it's not an ultra-portable featherweight, but it slips easily into a backpack for campus or cafe commutes.
The single-hinge design allows the display to open flat to 180 degrees. Physical ports include two USB 3.0 Type-A ports, a USB 3.1 Type-C port, an HDMI output, an SD card reader, and an audio jack. You also get a built-in optical disc drive—a feature that feels entirely nostalgic today, but takes up internal space that modern chassis utilize for batteries or cooling.
Real-World Performance and Bottlenecks
If you buy a secondhand unit that still runs on its original mechanical hard drive, Windows will crawl. Boot times can stretch past a minute, and routine multitasking causes severe stuttering.
The Storage Bottleneck
The single most important factor for this laptop is storage. Units equipped with a solid-state drive boot in seconds and handle browser tabs smoothly. If you pick up a cheap configuration with a spinning hard drive, budget for an immediate SSD replacement.
Gaming and Graphics
The optional NVIDIA MX150 GPU was designed for casual esports titles like League of Legends or older games at low-to-medium 1080p settings. It isn't a gaming rig. Modern AAA titles will bring the system to its knees. For office work, coding text editors, and streaming media, however, the graphics chip handles hardware acceleration without breaking a sweat.
Common Issues and Hardware Flaws
Before spending money on a used unit, keep these structural and functional flaws in mind:
- Poor Battery Life: The modest 35Wh battery was underwhelming even when new. Expect roughly 2 to 3 hours of real-world web browsing today, meaning you must keep the charging brick nearby.
- The M.2 Storage Quirk: While the motherboard features an M.2 slot, the physical placement right next to the optical drive means upgrading to an NVMe drive can be tricky or require removing the disc drive entirely. Most users find it easier to swap the primary 2.5-inch drive bay for a standard 2.5-inch SATA SSD.
- Display Limitations: The stock screens have limited color accuracy (low sRGB coverage) and dim peak brightness. Working outdoors or under direct sunlight is difficult.
- Thermal Management: Under heavy loads, the internal fans can ramp up, and older thermal paste often dries out, causing higher temperatures. Cleaning the vents and applying fresh paste revitalizes performance.
Upgrading the Lenovo Ideapad 520 15IKB
Reviving this machine requires targeted upgrades. Because 4GB of RAM is soldered to the board with only one open slot, you can expand total memory up to 12GB or 20GB depending on the stick you insert.
- Back up your data and power down the device completely.
- Unscrew the bottom plastic chassis cover, keeping track of screw lengths.
- Disconnect the internal battery before touching any internal components to prevent electrical shorts.
- Swap the hard drive for a standard 2.5-inch SATA SSD if the unit doesn't already have one.
- Add a DDR4 SODIMM RAM stick into the open slot to boost multitasking headroom.
- Clean dust out of the cooling fan using compressed air to maintain optimal temperatures.

Frequently Asked Questions
Can the Lenovo Ideapad 520 run Windows 11?
Models featuring the 8th-generation Intel Core i5-8250U officially support Windows 11 updates from Microsoft. Units with older 7th-generation processors lack official support, meaning you'll either stay on Windows 10 or switch to a lightweight Linux distribution like Ubuntu for better security and speed.
Is this laptop good for college students?
Yes, provided it has an SSD and at least 8GB of RAM. It handles essay writing, PDF reading, research tabs, and video lectures without issue. Just remember to pack the wall charger since the battery degradation over the years limits unplugged use.
How do I fix a lagging Ideapad 520?
Lag almost always stems from running a traditional mechanical hard drive or thermal throttling caused by dust buildup. Upgrading to an SSD and cleaning the internal heatsink fan restores snappy performance for everyday tasks.
Can I play modern video games on it?
No. The integrated graphics or entry-level MX150 card are restricted to older titles, indie games, and lightweight browser games. Modern graphic-heavy releases will experience severe frame drops.
