I recently bought a used HP 6560b laptop. After setting it up I discovered that the radio is turned off so I can't use my SIM card. After troubleshooting, I was told to turn on the switch by the side or use Hot keys. There is no switch (unless it's invisible to my mortal eyes) and there are no hot keys either. After a few google searches I was told I have to turn it on from the BIOS. Problem is that the BIOS is locked and I can;t trace the original owner.
Any help on unlocking it or turning on the radio will be highly appreciated.
