Thank you all very much for reporting the issue of overheating with the Surface Pro 3.
- Please make sure that you have all Windows updates. (The latest one is from 7/16/2014). If you already have them installed, please ensure that none of them failed to install.
- Could you describe what part of the device seems to overheat the most? Is there any particular area that gets hot, or is it the entire device?
- Do you have any accessories attached? (the Cover, microSD card, anything connected to the USB port)
- Try this two-button shut down:
Step 1: Press and hold the power button on your Surface for 30 seconds.
Step 2: Press and hold the volume-up button and the power button on your Surface at the same time for at least 15 seconds, and then release both.
The screen may flash the Surface logo, but continue holding the buttons down for at least 15 seconds.
Step 3: After you release the buttons, wait 10 seconds.
Step 4: Press and release the power button on your Surface to turn it back on.
