Is there a wireless hardswitch somewhere on HP Compaq 8510p

Power On Password & Hard Disk Password
With your next laptop you should protect it with a Power On Password AND put a password on your hard disk. This will stop anyone from using your laptop and if they move the hard disk from your laptop to another laptop they cannot access the data on your hard disk with the hard disk password.
BUT you need to write down or remember these passwords; if you lose or forget them you cannot gain access to your laptop.
There are no backdoor passwords to remove these passwords.
To set up or change these passwords, go to the BIOS configuration - then security configuration. http://techtips.salon.com/reset-hp-laptop-bios-password-1476.html

If the hard drive is compatible with your presario cq 41 then it will work. The operating system does not matter if you're switching hard drives.

If you want to update the operating system on the old hard drive, you will need to have the software for Windows 7.

Have you tried uninstalling and re-installing internet explorer again?
