Yoga 14 (type 20FY) screen turns off in tablet mode

2017-10-21, 19:40 PM

I have a Yoga 14 (Type 20FY) running Windows 10 64-bit, and my screen works fine in notebook, stand, and tent mode, but turns off the second I rotate it past tent mode and into tablet mode. I heard this may be related to a (relatively) recent Windows 10 update, but I honestly don't know. My computer is out of warranty and I have no income at the time, so I'd love to be able to fix this without taking it to a professional.

Hello tsukikage

Thanks for using the Lenovo forums.


Sounds like that could potentially be a problem. However with something like this, this could be down to a number of reasons.

 

Try to update the Graphics/Video and Chipset drivers from the support page:

https://support.lenovo.com/de/en

 

Try running an LSC scan and see if this is able to find any faults for you:

1. Please click on the following link

2. Under the section ‘Download’ select the relevant Hyperlink dependant on whether your Lenovo is running Windows 7/8/8.1 32 bit or 64 bit.
3. When prompted, select save and browse to a drive and directory in which to save the downloaded files.
4. Navigate to the folder where you saved the installation file, lscsetup_x86_26001.exe.
5. Double-click the installation file icon to start the installation.
6. Follow the onscreen instructions via the installation wizard that will install Lenovo Solution Centre on your system.
7. Once installed you will have a ‘Lenovo Solution Centre’ icon on your desktop please click to open this.
8. Once solution center is opened please select ‘Checkup’ then ‘Hardware Scan’ and ‘Full Scan’
9. This will take up to 20 minutes, see if this can find any errors.

 

 

If the above doesn't help, then the easiest way to rule out a software issue, is to perform a factory reset, and see if the issue persists.

Note: Please back up all your data as running this reset will delete any data on your machine

1. Turn the machine off and press the recovery button which is located usually next to the power button. If you have a desktop machine you will need to power the machine back on and keep tapping the F2 key.
2. Use the arrow keys and press enter on system recovery. ( Desktop users can skip this)
3. Select “restore from the initial backup” and then “Next”.
4. Click “start” and accept the warning messages.
Length of time can vary depending on the speed of the machine.

Hope this helps, let us know how you get on.

Thanks for your reply! I'm trying to work my way through your suggestions now. As for the LSC scan, apparently that's applicable to Windows 7/8/8.1, but I'm not seeing a link for Windows 10.

Nevermind - I was able to find LSC for Windows 10.
