How to open the Lenovo Legion Slim 7i / S7 (16″ Intel, Gen 8) – disassembly and upgrade options

1. Remove the Bottom Plate

– First, ensure the laptop is turned off and unplugged from any power source.
– Undo the 8 Phillips-head screws securing the bottom plate.
– Using a plastic pry tool, gently lift and pry the bottom plate off.

Note: The bottom plate comes with two cooling pads on the inside, specifically designed to help cool the SSDs.


2. Battery Removal

– The laptop features a robust 99.9Wh battery.
– Prior to proceeding with other components, always detach the battery connector from the motherboard for safety.
– To remove the battery, undo the 6 Phillips-head screws securing it to the chassis.

Note: The battery capacity provides up to 9 hours and 5 minutes of web browsing or 7 hours and 9 minutes of video playback. This is impressive given the device’s high-resolution display and powerful hardware.

3. Accessing and Upgrading the RAM

– The RAM area is shielded by a metal shroud which enhances cooling due to its thin thermal pad.
– Although 16GB of RAM is soldered directly to the motherboard, there’s an additional SODIMM slot available for expansion, allowing for an additional 16GB DDR5-5200MHz module. This means the maximum RAM capacity is 32GB.

Note: While the device might come with a 5600MHz memory stick, it operates at 5200MHz due to processor constraints.

4. Upgrading the Storage

– The laptop features two M.2 slots, both compatible with Gen. 4 SSDs.
– Should there be a Lenovo sticker on the preinstalled NVMe’s screw, it can be gently removed by pulling on it.

5. Cooling System Overview

– The device’s cooling solution is notably efficient for a slim gaming laptop.
– It consists of two fans and three thick heat pipes. The top two heat pipes are shared between the CPU and GPU, while the third is dedicated to the GPU’s memory and VRMs.

Hint: For optimal performance and longevity, it’s advisable to routinely clean the fans and replace thermal paste if needed.

To reassemble, follow the steps in reverse order, ensuring all screws are securely tightened and all components are properly connected.
