I use a HDD from a Satellite A205 and install it on a ProBook4430. Some how the Sat.A205 ended up with a Bios lock and asked for a password .(I NEVER PUT A PASSWORD ON IT! ) I have the ProBook4430 working except missing drives and can't get WiFi to work to download. Any advice is greatly appreciated.
For drivers for the ProBook you'll have to use a different PC which has internet access. Download the drivers for that model from HP Support, copy them to a pen drive, then plug the pen drive in to the ProBook and install the drivers which you copied to it. It's very easy and simple, not rocket science.
