Yoga 370 Intermittent black screen and keyboard lockout

On Yoga 370, from once per hour to once per every two characters typed, laptop screen goes black and keyboard is locked out (if I keep typing, all characters may not be captured). This can happen:

 

  • While actively typing (potentially only happens when actively typing)
  • While plugged in
  • While not plugged in
  • While connected to a lenovo dock (and monitor goes black as well)
  • While not connected to a lenovo dock
  • Following a recent restart
  • Without a recent restart

This is extremely disruptive. Please help!

No, I rarely use Chrome on this laptop as it is not the default browser in the build.

Re: Yoga 370 Intermittent black screen and keyboard lockout

Hi, welcome to the forums.

 

It will be interesting for you to validate that your Yoga 370 is on the latest BIOS and driver levels just to rule out any outdated driver.

Use Lenovo Vantage to update the BIOS and drivers of your machine. After that check the support site of your model and validate that you are on the latest driver level too.

 

What I would try to test in your case, is to try to rule out if there is a Windows problems or hardware. For example, I would get into the BIOS (or even boot some Linux USB Flash) and stay there for a while to see if the screen also goes black. If it happens it will possible tell me that is a problem outside Windows and more related to hardware. If there is no issue it may be a problem with Windows configuration and drivers. Check it out.

 

Also, A diffent approach can be a to run Windows 10 in safe mode and see if it remains stable. If it remains stable on Safe mode it may indicarte it is a software issue.

 

I hope this helps.
