Lenovo Legion 5i (15IRHX10) Disassembly Guide: Upgrades, Internals, and Battery Access

Accessing the Internals of the Lenovo Legion 5i Gen 10

For enthusiasts and professionals looking to extend the lifespan or upgrade their Lenovo Legion 5i (specifically the 15-inch, 15IRHX10, Generation 10 model), understanding the internal architecture is crucial. Unlike many modern ultrabooks that are glued shut, this gaming laptop retains a user-friendly design philosophy, allowing for straightforward maintenance and hardware expansion without voiding warranties or requiring specialized adhesive removal tools. The process begins with the exterior. To gain access to the motherboard, cooling system, and storage drives, you will need to remove ten screws from the bottom panel. It is important to note that these are not standard Phillips head screws; they utilize a JIS (Japanese Industrial Standard) number one driver. Using the correct tool prevents stripping the screw heads, which can make subsequent removals difficult. The first four screws located near the hinge area are notably shorter than the rest. Keeping track of screw length and position is vital during reassembly to ensure proper sealing and structural integrity. Once all ten screws are removed, the bottom cover does not simply lift off. It is secured by plastic clips around the perimeter. Using a thin pry tool or a guitar pick, you can carefully release these clips. The key here is patience; inserting the tool too deeply risks damaging internal ribbon cables or scratching the chassis. Once the clips are disengaged along all edges, the bottom cover lifts away cleanly.

Power and Storage Configuration

With the bottom panel removed, the first critical step in any maintenance procedure is safety. You must disconnect the battery connector from the motherboard before proceeding with any other component removal. This prevents short circuits that could damage sensitive logic boards. The battery itself is an 80Wh unit, a substantial capacity for a 15-inch laptop, and it supports Lenovo’s super rapid charging technology as per official specifications. Removing the battery involves unscrewing its mounting bracket from the chassis base. Beneath the thermal shielding lies the storage subsystem. The Legion 5i Gen 10 is equipped with two M.2 SSD slots. One slot houses a Samsung 1TB NVMe drive in an M.2 2242 form factor, while the second slot remains empty out of the box, offering immediate room for expansion. Both slots support PCIe 4x4 interfaces, ensuring high-speed data transfer rates compatible with modern storage standards. The primary SSD is covered by a shared EMI (Electromagnetic Interference) shield that also serves a thermal function. This shield helps distribute heat from surrounding components and features a thermal pad underneath to improve contact with the motherboard’s passive cooling elements.

Memory and Processing Units

Underneath the same EMI shield covering the primary SSD, you will find the system memory. The laptop utilizes two SODIMM slots capable of dual-channel operation. Lenovo officially supports up to 32GB of DDR5-5600MHz RAM in this configuration. This upgrade path is significant for users who need more memory for multitasking, virtualization, or heavy creative workflows without replacing the entire system. The central processing unit (CPU) and dedicated graphics processing unit (GPU) are located centrally on the motherboard, surrounded by their respective voltage regulator modules (VRMs). The cooling solution employs a dual-fan setup designed to manage thermal output from these high-performance components. While this guide focuses on disassembly rather than cleaning or repasting, accessing these areas allows for dust removal which can significantly impact long-term performance stability.

Connectivity and Peripherals

The wireless connectivity module is also easily accessible. Located near the edge of the motherboard, the Wi-Fi and Bluetooth card is secured by a single retaining screw. The antenna cables connect directly to this card, allowing for potential upgrades to newer Wi-Fi standards if compatible cards are available in the future. Finally, examining the underside reveals the touchpad assembly situated beneath the speaker grilles. This layout maximizes internal volume for cooling while keeping input devices responsive. Understanding these spatial relationships helps users navigate the chassis without accidentally damaging ribbon cables that connect the keyboard or trackpad to the mainboard.

Why Upgrade Your Legion 5i?

The decision to open a laptop often stems from specific needs: running out of storage space, needing more RAM for professional applications, or replacing an aging battery. The Lenovo Legion 5i Gen 10 is particularly well-suited for these upgrades due to its accessible design. For gamers and content creators, the empty second M.2 slot provides a cost-effective way to expand storage without migrating data from the primary drive immediately. PCIe 4x4 speeds ensure that even secondary drives perform at high velocities, reducing load times in games or video editing software. Similarly, upgrading RAM to the maximum supported 32GB of DDR5-5600MHz can alleviate bottlenecks in memory-intensive tasks like compiling code, rendering 3D models, or running multiple virtual machines simultaneously. Battery replacement is another common reason for disassembly. Over time, lithium-ion batteries degrade, leading to shorter runtimes and potential swelling issues. The straightforward removal process of the 80Wh battery makes it easier for users to maintain their device's power health independently.

What Works Well

* **Tool Accessibility:** The use of standard JIS screws rather than proprietary Torx or pentalobe heads simplifies maintenance for most technicians and DIY enthusiasts. * **Expansion Options:** Having two M.2 slots and dual RAM slots out-of-the-box provides excellent upgrade potential right from the start. * **Thermal Management Design:** The shared EMI shield acting as a heat spreader demonstrates thoughtful engineering that aids in passive thermal distribution for components like the SSD and RAM.

Where It Falls Short

While the disassembly process is relatively straightforward, users must remain cautious with the plastic clips securing the bottom panel. These can break if forced aggressively during removal or installation. Additionally, while the internal layout is clean, accessing the CPU and GPU for thermal paste replacement requires removing the entire cooling assembly, which involves more complex steps than simple component swaps like RAM or SSDs.

Who Is This For?

This guide and the laptop itself cater to students, developers, gamers, and professionals who require a powerful machine that can be maintained and upgraded over time. It is ideal for users who want to maximize their initial investment by adding storage or memory later, rather than buying a higher-spec model upfront. The accessibility also appeals to IT departments managing fleets of laptops where quick battery swaps or RAM upgrades are necessary.

Final Thoughts

The Lenovo Legion 5i (15IRHX10) Gen 10 stands out in the gaming laptop segment for its balance of performance and serviceability. By allowing easy access to critical components like storage, memory, and power sources, Lenovo empowers users to tailor their devices to evolving needs. Whether you are expanding your library with a second SSD or refreshing an old battery, this model provides the hardware foundation necessary for long-term usability without requiring professional repair services for routine upgrades.
