My laptop freezes when I slightly move the display or close the lid or just try to adjust the screen. Freezes completely, sometimes when I do it really carefully it keeps working, sometimes it goes to sleep but when I try to open it freezes. I can freely move around the laptop itself and everything works fine. I know for sure it’s not my ssd/ram/OS/. If someone happen to know what it could be or at least could name anything that could help me locate the problem it would be great.
Replace wifi card. Make sure the thermal pad is still there.
I suspect your hinge is loose and the wires are getting cut causing the system to freeze. Follow this IFIXIT guide to check the hinges as well as the wires leading into the display: MacBook Pro 13" Unibody Mid 2009 Left Clutch Hinge Replacement. You should only need to go upto Step 10. If the hinge is loose within the display lid you’ll need to pop off the clutch cover to gain access to the lid side screws. Heres the Right side hinge guide: MacBook Pro 13" Unibody Mid 2009 Right Clutch Hinge Replacement picking things up from Step 18 for it.
