The Lenovo Yoga C940 is a popular 2-in-1 laptop that offers impressive performance and features, but taking it apart can be a daunting task without proper guidance. In this article, we will walk you through the process of disassembling a Lenovo Yoga C940, providing detailed instructions and tips to ensure a successful teardown.
Tools Required For Disassembling A Lenovo Yoga C940
To successfully disassemble a Lenovo Yoga C940, you will need the following tools:
1. Screwdriver set: Ensure you have a set of precision screwdrivers with various sizes. This will help you access and remove screws of different types and sizes within the device.
2. Plastic spudger or opening tool: Use this tool to pry open the casing without damaging it or any delicate internal components. A plastic spudger is recommended to avoid scratching the surface.
3. Tweezers: These are useful for gripping and holding small screws or components during the disassembly process. Having a pair of tweezers with a fine tip can make handling tiny parts much easier.
4. Anti-static wrist strap: Wearing an anti-static wrist strap will help prevent any electrostatic discharge that can potentially damage sensitive components. Make sure you connect the strap to a grounded metal surface.
5. Thermal paste and isopropyl alcohol: If you plan on reapplying thermal paste during reassembly, ensure you have a small amount of high-quality thermal paste and isopropyl alcohol to clean the surfaces.
Having these tools ready will make the disassembly process smoother and reduce the risk of damaging any internal components.
Step 1: Removing The Bottom Panel
In this step, we will guide you on how to remove the bottom panel of your Lenovo Yoga C940. This is the first crucial step when disassembling the laptop. Before starting, ensure that you have all the necessary tools ready. You will need a small Phillips screwdriver, a plastic spudger, and a prying tool.
To begin, shut down your laptop and disconnect any external power source. Flip it upside down and locate the small screws that secure the bottom panel. Use the Phillips screwdriver to remove these screws and place them in a safe container to avoid misplacing them.
Once the screws are removed, use the plastic spudger to gently pry open the bottom panel. Start from the edges and work your way around, applying light pressure. Be careful not to use too much force, as you don’t want to damage the panel or any internal components.
After successfully removing the bottom panel, put it aside in a safe place. This will give you access to the internal components of your Lenovo Yoga C940 for further disassembly.
Step 2: Disconnecting The Battery And Keyboard
In this step, you will learn how to safely disconnect the battery and keyboard from your Lenovo Yoga C940.
First, make sure you have the necessary tools for the job, such as a Phillips screwdriver, a plastic spudger, and an anti-static wristband. These tools will help you handle the delicate components properly and prevent any damage.
Start by removing the bottom panel of the laptop, as explained in Step 1. Once the panel is off, locate the battery and keyboard connections. The battery is usually connected by a cable, while the keyboard is held in place with a few screws.
Using the plastic spudger or your fingers, gently disconnect the battery cable from the motherboard. Be careful not to pull too hard or damage the cable. Next, remove the screws securing the keyboard and carefully lift it off the laptop.
Remember to handle all components with care and avoid applying excessive force. Disconnecting the battery and keyboard is an important step to safely disassemble your Lenovo Yoga C940 and proceed with further component removal.
Step 3: Removing The Display Assembly
Removing the display assembly is a crucial step in disassembling the Lenovo Yoga C940. This step requires patience and careful handling to avoid any damage to the delicate components.
To begin, use a plastic pry tool or a guitar pick to carefully remove the rubber screw covers around the display bezel. Once the screw covers are removed, you will find several screws securing the bezel in place.
Next, unscrew these screws and gently pry open the display bezel using the plastic pry tool. Be cautious while doing this to prevent any unnecessary force that may cause cracks or damage.
Once the display bezel is removed, you will see the display cable connected to the motherboard. Carefully detach the cable by pulling gently and disconnect any other cables that are attached to the display assembly.
Lastly, detach the display assembly from the main body by removing the screws that hold it in place. Be sure to keep these screws in a safe place as they will be needed when reassembling the laptop.
By following these steps, you can successfully remove the display assembly of the Lenovo Yoga C940 without causing any harm to the internal components.
Step 4: Detaching The Motherboard And Other Internal Components
In this crucial step, we will guide you through the process of detaching the motherboard and other internal components of your Lenovo Yoga C940. Before proceeding, ensure that you have completed the previous steps and have all the necessary tools at hand.
1. Disconnecting the connectors: Start by carefully disconnecting all the cables and connectors attached to the motherboard. These include the display cable, Wi-Fi card cables, audio jack, and any other connections you find.
2. Removing the screws: Next, locate and remove the screws securing the motherboard to the casing. Keep these screws in a safe place to avoid misplacing them.
3. Detaching the motherboard: Gently lift the motherboard out of its position, being cautious not to use excessive force or twist it in any way. Ensure that no cables or components are still connected before completely removing the motherboard.
4. Removing other internal components: Now, you can proceed to detach any additional internal components that you wish to replace or repair. This may include the RAM, storage drive, or other expansion cards.
By following these steps diligently, you can successfully detach the motherboard and internal components of your Lenovo Yoga C940. Remember to keep the removed components in a safe location and handle them with care to avoid any damage.
Step 5: Reassembling The Lenovo Yoga C940
After successfully disassembling your Lenovo Yoga C940, it’s now time to put everything back together. Reassembling the laptop may seem daunting, but by following these step-by-step instructions, you can easily restore your device to its original state.
1. Begin by reattaching the motherboard and other internal components. Make sure all the connections are secure and properly aligned. Double-check the alignment of any ribbon cables or connectors.
2. Next, carefully attach the display assembly back onto the laptop. Ensure that the connectors are properly aligned and gently press the display down until it snaps into place.
3. Now, reconnect the battery and keyboard. Once again, ensure that the connections are secure and properly aligned.
4. Take the bottom panel and align it with the laptop’s chassis. Gently press it down until it snaps into place. Use the appropriate screws to secure the panel in place, following any markings or guidelines present.
