Hi there

I own a Lenovo Yoga 730 (approx 3 years) Since about 1 Year i get frequent problems with the Keyboard, some keys seem to work/not work for no clear reason (in my eyes).

In the past i have sent the laptop to Lenovo because of random crashes (bluescreen) and they said nothing was broken and just reinstalled BIOS and OS. I haven't had any issues of crashing since then, but shortly after it startet to have problems with the keyboard.

In the beginning maybe once a week, now almost daily. Sometimes they are "off" for a short time sometimes it takes 2 hours until they work again...

The Key's that are not working:
Shift (left) Caps, Tab, °, T, Y, F3 and F7 also Backspace, ! and [.
I did test this with en.key-test....

As the Laptop is out of warrenty i already open it and checked if it has a kink, cleaned the connector with pure alcohol but it diden't help.
My biggest issue is that its coming and going with no clue why. If the keys do not work they do not work anywhere (also command prompt run by admin).


As said:
Lenovo Yoga 730-13IWL, running latest Windows 10 with all updates, driver and Bios also up to date.

EDIT:
  • I have tried to uninstall the keyboard and update drivers - no result
  • Touchscreen and On screen keyboard are working fine
  • Scanned for Viruses - no result
  • unfortunatly no external keyboard available to test :-(
Happy to hear your thougts on it.
