I noticed my mom's mid-2015 MacBook Pro had a slight convex bulge the other day (3-4 days ago), and fast forward to today, the laptop now pushes the display so the display isn't flush as it was. (about half an cm) I googled the problem and I advised her to completely unplug the laptop and discontinue using it for now, is there any advice what I should do? We're thinking about getting a new one for her ASAP because she can't work without her laptop and she's due for an upgrade. Also, is it safe to keep using it in Desktop mode via a monitor? Thank you!
