Hi,
Thank you for letting us know. Let's sort this out. Surface won't power on can be associated with several issues: it can be heat related, failing hardware, issues with Windows. Let's try to troubleshoot this issue while the PSU is attach on your Surface:
- Press and hold the power button until the screen turns off (about 10 seconds), then release the power button.
- Press and release the power button to turn your Surface back on. You should see the Microsoft logo.
Additionally, undock and disconnect all extra peripherals and leave your Surface plugged in to the power supply that was included with the device, but remove everything else that’s connected to it, including the accessories, adapters, external monitor, and MicroSD card. Then, disconnect your Surface from the docking station if you’re using one. Press the power button once to turn on your Surface.
If you would like me to provide additional advice, simply respond to this thread. I will get notified and I’ll reply to you as soon as I can.
Regards.
