my yoga 500 screen turns black when i touch it

Dear All,


whenever I use the touchscreen with my fingers, it turns off and I need to press any normal key to turn it on again. 

any ideas why? I checked the cable and it is fine.

Hello Benoitlotfallah

Thanks for using the Lenovo forums.

Sounds like this will be a power issue, Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

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