@kishan_kkk1 Welcome to HP Community!
There are two common keyboard issues that can occur during the normal operation.
The first is the Num Lock key gets accidentally pressed, turning a portion of the keyboard into a number pad.
The other is the keyboard language gets inadvertently switched from its original language to another, resulting in some letters and numbers appearing different on the screen than how they are typed.
Check the Num Lock key, Set the keyboard language, Update the BIOS and device drivers:
If you experience is persistent with the keyboard errors, such as the keyboard frequently switching modes,
try updating the notebook's BIOS and device drivers.
For more information, see HP Notebook PCs - Locate and Install Updated BIOS, Drivers, and Software.
