I'm tired of all these issues now. At first, a few days ago, I was working on this laptop and it shut down randomly. I switched it on, but again it shut down randomly. In 20 minutes, this happened thrice. I tried something, and then it worked fine for a day. Then today again, it is happening. The diagnostic kit says there's nothing wrong. Please help.
So I got my new Surface Pro 7 at the end of April 2020. Two days days later I started having the exact same issue. Sometimes it would shutdown multiple times in a row. I went through all of these threads and researched this issue and even tried updating the drivers(with no success). There apparently hasn't been a firm update/patch to fix this issue (yet). However, I discovered a what seems to be a great work around on notebookcheck.net. I downloaded Intel Graphics Command Center from Microsoft Store, and disabled Panel Self Refresh. This setting is under System>Power>Panel Self Refresh (Battery & Plugged In Tabs). My Surface Pro 7 has not turned of randomly or froze up once since I changed this setting. I really hope this may help individuals having these issues until a firm update comes out.
