hello i got free macbook pro i think its 2010 or 2011 from what i see it has 8 gb ram when i tried to start it it wont boot or power on. so i tried removing back plate and disconnect the battery and starting to hold power for 10 secs after that plug the power,and keep holding for another 10 secs, then i can power it on. it works,but.. when i power it on there is no chime,fans run at full speed,i get white screen for 10/20 seconds and then apple logo shows and starts loading. also i noticed hdd is defective (clong sounds). if i try to reset SMC with shift+control+option+power it wont power back on,ill have to try again with the 10 seconds power thing. can i fix it ?
