I programs uninstall has been and must have uninstalled biometrics.  Thing is the pass simple hp with my fingerprint has been my admin (for some reason, I never wrote or remember the password typed and always just used my fingerprint) so now I can not reiinstall the biometric pilots cause it asking me to enter the password or slide your finger , but for the finger swipe light does not illuminate and now I can't restore anything.  What is the solution for that to be resolved.  Can I try before buyiing a restoration kit.

Try doing a system restore. Immediately after turning the power on, press the F11 key to start in the Recovery Manager. Once there - choose Microsoft System Restore. Do NOT choose a system recovery , unless you want to return the laptop to factory settings.

Once the system restore comes up, choose a date before the problem began to restore.
