Thanks.

P.S. Sorry for my bad english.

I have bought a used MacBook Pro, when problems arise, opening Corps was trying to turn the screw, but with poor quality could not turn a screwdriver, only to ruin the screw. Try to buy ifixit Screwdriver set. Good luck to all and thank you ifixit team for such assistance as ifixit.com. Thank you.
