My MacbookPro6,2 was experiencing GPU Panics. There are a lot of reports with regards to Apple previously replacing the boards and after a little while, the problem reappears. I did a lot of research on this issue when my MBP started to crash (GPU Panic) 5-6 times a day. Results from my research, the issue is the Tantalum capacitor used to regulate power to the dGPU. When the dGPU is running at high performance settings, it requires a lot more voltage. Because the bad capacitor can't handle the voltage anymore, it cause the GPU Panic. Solution was to replace the bad tantalum capacitor; not just with a similar part! If you do that, you'll end up with the same issue later down the road. The solution is to replace the bad capacitor with a better part! Louis Rossmann recommended using Aluminum Polymer capacitor because they are highly reliable! Here is the link to his video (https://youtu.be/DzcgT_fiVTA) ... just don't mind the language used! I used a Panasonic Aluminum Polymer Capacitor (https://www.digikey.ca/product-detail/en/panasonic-electronic-components/EEF-SX0E331ER/PCE4827CT-ND/1731710). Since I had the logic board out of the laptop enclosure, I decided to clean and replace all the original thermal paste that Apple applied. Note ... it is quite the mess they've created! Using more than actually needed. [image|998668] [image|998669] [image|998670] [image|998671] [image|998672] Last image highlights the Aluminum Polymer Capacitor I used in my fix. Overall results ... no GPU panic since replacing the bad capacitor. MBP is running very smoothly.
