Hello sir, my laptop model is HP Pavilion 15-BC406TX . Actually my problem is after giving the last month's windows cumulative update. Some functions and some major character keys of my key board dose not work . But when I run keyboard diagnostic from boot menu it shows my keyboard is absolutely ok and every key is working fine.
@Avijit_Saha If your keyboard is not working only in windows, try the following steps:
Shut down the computer.
Press the Power button, and then immediately press the Esc key repeatedly to open the Startup Menu.
If the Startup Menu screen does not open, the integrated keyboard hardware is not working. Service or replace the integrated keyboard in the notebook. To continue using the notebook, connect a USB wired keyboard to a USB port, and then restart the computer.
Press F10 to open the BIOS settings.
Press F5 to load the default settings, and then press F10 to accept the changes.
Restart the computer.
In Windows, search for and open Device Manager.
Click View, and then select Show hidden devices.
Click the arrow next to Keyboards, right-click the keyboard name, and then click Uninstall to remove the device from Windows.
Remove all devices in the Keyboards category, and then restart the computer.
The keyboard should now work correctly.
