Chosen Solution
I have noticed in that past 24 hours that two rigid and straight “lines” have developed as bulges on my Mid 2010 Mac Book Pro 15 inch. They are noticeable when looking at it in the light and you can e asily feel that they are raised above the case. They appear on the outer shell of the case (right of the mouse and near the keyboard) The bottom of the Mac is not warped. The hard drive also appears to be in good condition. Initially I thought this was due to a battery failure and removed the battery. Despite this, the battery was fine (not warped or bulging). I noticed that the two bulges in the case appear over where the hard drive is in a Mac Book Pro. There is also a “semi circular” bulge near these two lines. What could be causing these if it is NOT the battery? Also, is there any chance that these bulges could expand? Edit: After further inspection it appears to have occurred exactly over the bridge that holds the hard drive in place. (the long black piece with the two screws in it). The bulges appear as two straight lines… they are difficult to see but look closely under the arrow keys
The second image (below) shows what is under the bulge. Maybe something looks out of place?
Edit: I noticed the two lines are exactly the same width as the black bar holding the hard drive in place.
Did you bang the bottom? It looks like the force from the bottom pushed the rail up Or, did you bang the top with the lid up? As the drive flexed and the rail didn’t it created the crease. You’ll need to live with it our replace the upper case which is expensive given the fact the system is working.
