Troubleshooting Overheating and Thermal Paste Problems in Lenovo IdeaPad Laptops

Hello, tech enthusiasts!

I recently encountered some significant issues with my child’s Lenovo IdeaPad that I believe many of you might find relatable. The laptop started to exhibit persistent Blue Screen of Death (BSOD) errors and would freeze whenever it was moved. Now, it has reached a point where it becomes completely inoperable and shuts down within two minutes of light usage. Interestingly, it successfully passed all BIOS diagnostics, which left me scratching my head.

Upon opening up the laptop for a thorough inspection, I discovered an alarming amount of thermal paste improperly smeared on the back panel, along with some on the SSD tray. This was surprising, as I couldn’t find any reference to thermal paste in Lenovo’s support documentation or in several teardown videos I watched.

Given this situation, I’m left wondering what could have led to this unusual application of thermal paste. Could it be a manufacturing oversight? Whatever the case, I’m eager to find a solution and am well-prepared for the repair process. I’ve already ordered some high-quality thermal paste and am ready to get started!

If you’ve faced similar thermal issues with your Lenovo laptop or have insights into this peculiar situation, I’d greatly appreciate your guidance. Below, you’ll find images showcasing the laptop before the teardown and what I found during the process. Your expertise could be invaluable in helping restore this device to its former glory!

  1. Hello, and thank you for sharing your detailed experience. It appears that the improper or excessive application of thermal paste can cause several issues, including overheating, thermal throttling, and potentially hardware instability like BSOD errors or system freezes.

    In your case, the thermal paste found outside of the intended heatsink area—such as on the back panel and SSD tray—is concerning. This suggests a few possibilities:

    • Manufacturing defect or oversight during assembly where thermal paste was incorrectly applied or spilled over during installation.
    • Possible damage or wear over time causing the paste to spread beyond the heatsink contact area.
    • Improper reassembly after a previous repair, leading to excess thermal paste contamination.

    To address this issue effectively, I recommend the following steps:

    1. Careful Removal of Excess Thermal Paste: Use isopropyl alcohol (preferably 90% or higher) and a lint-free cloth or coffee filter to gently clean the thermal paste from the back panel and SSD tray. Ensure all residue is thoroughly removed without damaging components.
    2. Check the Heatsink and Fan Assembly: While the laptop is open, inspect the heatsink for correct installation and ensure there’s no excess thermal paste applied between the CPU/GPU and heatsink. Reapply thermal paste only as needed—typically a small pea-sized amount on
