Hello;
Allow me to welcome you to the HP forums!
Sorry to be the bearer of bad newes, but you should not have downgraded your Win10 laptop to Win7.
Laptops especially contain specialized hardware for which, for full functionality, specialized drivers are required -- and these come ONLY from the OEM, in this case, HP. Your PC came preinstalled with Windows 10. Since you removed or overwrote the original Win10 on your PC with Win 7, you are going to encounter serious problems as there are no HP Win7 drivers for the new hardware that comes with new machines.
MS supplies drivers that provide only basic functionality. This means that some of the hardware functionality is likely NOT to work if you force a downgrade. That includes functions like the touchpad, WiFi, swtichable graphics, USB ports -- to name the functions commonly reported here.
If you want full functionality for the machine, you need to restore it to its original factory settings using HP Recovery Media.
Good Luck
