I have been using this Yoga 260 (Windows 10/64bits) with touch screen for the last 2 years without any problem. Since the past Sunday, I noticed that the system would hung up or frozon when I used certain CRTL key functions, such as, CTRL-C, -V, -Z, -X. First noticed it while doing PPT (2013). Same thing happends with any Word, excel, and other apps. I could only power down and power up the laptop once it hung up. I ran Lenovo Solution and Lenovo Vantage, and it passed all the tests. I made sure that I have the most up-to-date BIOS, and OS. The problem is still there. I then used an external USB keyboard. No problem at all then. As soon as I used the laptop keyboard, and press CTRL-C or other CTRL-combination, then the system would hung up. Hardware problem? Any suggestion how to fix the problem?
Solved! Go to Solution.

Do you have the same problem with both left and right CNTRL buttons?

Thanks for asking!
Honestly, I didn't try to use the right hand CTRL key to see if it would hangup the system. After I had posted the question, I downloaded a keyboard test app, and it shows that the codes generated by the laptop keyboard are all correct. With the same test app, then I tried to press CRTL-C repeatedly, but slowly, everytime the code was correct, but by the fifth time, the system hungup.
Since the keyboard test, I returned to using Excel for testing. After entering some characters in a cell, I then copied the value to another cell. Again, the system would crash. And it would give me the Blue Screen with error messages. I got two different kinds of error messages:
- "Windows 10 crashing on IRQL Not less or Equal Error", or
- "stop codeAGE fault in nonpaged area"
and generated the three log files and MSINFO32 files. But the problem still there.
Any suggestion what should i do to fix the problem? Any other info is needed to help me troubleshoot?

I did the "chkdsk /f /r" then followed by "sfc /scannow" which took about 4 hours to complete.
After that, the CTRL-key problem is gone. But, MS Outlook was not to able to load. I uninstalled the MS Office, and reinstall it again.
The problem is gone. The system runs stable in the last two days without a problem!
Thanks again for trying to help!
