hp charging issues.

Please helpp!!!!
i have been having a strange problem with my laptop pavillion g6model. My laptop works fine on battery.. When i plug in the charger the laptop freezes and when i start it up again. telling me boot devicd not found.. error log 03F0 which i think a code for not finding the hard disk drive.
I run the hard disk test which comes " hard disk not exist."

then i press f9 or f10. enter bios. i restore factory settings. and restart. it works fine and i manage to reach my desktop did some backup of some important folders.. i here the hard disk making a creaking sound. it continues to work though.

then When i plug the battery socket again to charge it freezes my computer again and when i restart it tells me again boot device not found. does not recognise hdd etc.

now:what i did i took a charger from my friend. it stills does not charge. meaning my charger is fine.
i took the ram and hdd cleaned then and re inserted then thinking they were loose. the problem is not there too. and my laptop will not run on electricity. it frrezes my pc. but it works fine fwith the battery.

please help me out. anyone had such issues?
