It is possible small debris has entered these keys and is inhibiting function.  Use a small vacuum nozzle, to clean out and perhaps some gentle scraping around the gaps.  Tilting the PC to large angles may help move the debris aside.  Unfortunately the keyboards are provided as permanent assemblies, not intended for disassembly and reassembly.  For laptops the OEM is often the only source for replacement keyboards.


To test electronic malfunction, try using external keyboard.  Wired USB is the basic expectation.  Bluetooth may work, but a functioning keyboard on the laptop is needed to set it up.


Lenovo Vantage Hardware scan may have a keyboard analysis feature.  It also will suggest appropriate needed device drivers, with the appropriate command entry to Vantage program.
