HP/Compaq :: How To COMPLETELY Remove A Webcam Driver

a new 6730b and the one serious remaining problem I have is that the battery, even though plugged in on AC, displays as 'plugged in not charging'.

I've discovered - by endless hours of hard slog - that the webcam driver is actually the issue here. I've uninstalled the chicony software and, on the few occasions that I've succeeded in uninstalling the driver & kept it uninstalled for the next start-up, the battery recommences charging. But in recent days it's reverted to reinstalling the driver on start-up, and stopping the battery recharging.

I can't seem to permanently remove the driver, no matter how hard I try. And I really, really want to!
The driver uninstall or disable in Device Manager only gets rid of it until the next start up (and unless I can restart without it reinstalling, the battery doesn't get kicked into recharge).

I've even tried deleting the driver from WindowsSystem32drivers - I changed all the permissions to enable me to delete and... deleted it! Even double checked that it had gone to the recycle bin. Yes, it's there.

But I restart after all this and the damn thing has magically put itself back in the same file.
