Top 3 fixes for: Lenovo Yoga S730 shuts down without warning under Windows 10

I've recently purchased this nice little beast: the Lenovo Yoga S730-13IML laptop (81U40018SB)
  • 10th-generation Intel Core i7-10510U (4C / 8T, 1.8 / 4.9GHz, 8MB)
  • 16 GB RAM
  • 1 TB SSD
  • 13.3" 1080p screen
  • 3x USB-C ports
  • 42W battery
  • Fingerprint sensor
I've been using the standard Windows 10 Home OS that came with it and set the power plan to 'Maximum performance'. I wanted to ensure I'd get my money worth in terms of computing power. I noticed the laptop was getting a bit hot but without any particular issue.

After a few weeks of use, I started getting unexpected shutdowns. In a single morning three consecutive shutdowns without warning. The screen goes black, power LED goes off, it's like the juice is gone. I can turn it back on immediately but once it gets hot again (or so I suspect) it shuts down again. I tried changing settings back and forth and finally found a configuration that doesn't crash anymore, so I thought I would share it with the community. No crash for several days now. Here is what I changed, I recommend you apply all of these together to maximize your chances:

1) enabled 'Intelligent cooling' in Lenovo Vantage (not certain this did the trick but I have it enabled anyway)


2) my battery settings are as follow (again not certain that this is what did the trick but I'm showing you anyway):


3) the Windows power plan: I think this is the most important setting here. Do NOT set it to 'best performance' on the far right. I changed it back to 'Better performance' several days ago and haven't had a crash since.


This reminds me of an issue I had with the Macbook Air under Windows (with Bootcamp) it would crash if I didn't set it to 'best performance', so kind of the opposite of what's happening here! Anyway, been monitoring CPU temperatures and it seems like my Yoga was really getting too hot under the 'Best performance' plan, so that may explain the issue. Franckly, performance wise I don't see much difference with the new plan I'm using. Hope this helped someone.

If this did not help you, maybe check this article from Tom's hardware about Lenovo computers crashing at random.

Other than that I'm quite happy with this new laptop overall! Very sleek design, lightweight, and still quite the powerhouse. Good job Lenovo!
