Internal Keyboard showing as Standard PS/2 Keyboard in Device Manager

Sr, I am using Windows 10 on my Lenovo Laptop. My PC was OK till I connected a PS/2 keyboard on it. After I disconnected that PS/2 keyboard, My internal Keyboard is badly working i.e it is autotyping a particular key randomly and whenever I go on Device
Manager, The keyboard Driver is showing as Standard PS/2 keyboard though there is not any PS/2 keyboard connected. I have uninstalled the keyboard driver and restarted my PC but there is a beeping sound and the Standard PS/2 keyboard driver is back on device
manager. I have also removed my internal Keyboard and reinstalled it but no difference was made. I have also attached the Standard PS/2 keyboard again but nothing worked. I also uninstalled and reinstalled Windows 10 but nothing actually worked. Should I buy
a new internal Keyboard? Will that fix the problem? I actually don't know why is my internal Keyboard is showing as Standard PS/2 keyboard in device manager. Please help and suggest me what to do to fix this.
