I've seen something similar on another Lenovo and it needed the Intel chipset drivers installed first. Try using ext mouse/kbd to do that, or try using the Lenovo recovery image for that model (which installs the drivers automatically).

Hi
Do you have BIOS for it?

I tried by installing chipset drivers but no luck.

Are there any yellow exclamation marks in Device Manager? Have you tried the Lenovo recovery image for this model?

I have experienced a similar issue with an HP 2-in-1 laptop recently. Both keyboard and the touchpad work in BIOS but stop working in Windows. I believe the issue is with the sensor that thinks computer is in tablet mode all the time, hence it disables the keyboard and the touchpad. The motherboard definitely has a problem but I found the workaround. Go to Device Manager and under System Device locate something that says Intel Sensor. Disable it, then reboot the machine. Then go to the BIOS and choose to restore to factory settings. Save and reboot. You should now get the keyboard and the touchpad functionalities back, You will lose ability to rotate the screen because of the disabled sensor but it's a small price to pay for a working computer.

Let me know if this helped you.
