Please I need help before star with this new project.. someone give me this MacBook Pro 2011 but the battery was already fat defective from one side completely dead and it was without hard drive I test it with the defective battery and need to keep it TURN On all the time with the power adapter and I used SSD 250GB Crucial M500 it installed OS X lion but was running very slow even with the new SSD I was very disappointed about the speed and delete the SSD I was ready to recycle it but after checked some comments I found that if I use only the main power from the charger the cpu clock or processor run slow with out the battery ,now I know that I need new battery and I already order one to have the MacBook Pro runs normal speed . My Question is and please help me with this what is the best way to do it Do I need to install the new battery at the same time install the SSD and install OS X star from 0 gain ,Or Do I need to install again the SSD and install the OS X with out the battery only using the power adapter and install the battery after arrives because is going to be. very slow again without the battery but I. think with the new battery is going to be faster with the SSD ...MY last question does this MacBook Pro have a SATA III connection? thank you everybody
