Sometimes my MacBook Air trackpad freezes. (Trackpad Problem)
Device info : MacBook Air 11-inch Early 2015
Battery Cycle : 170
Hello! I have a question about a problem with my MacBook Air.
When I'm using my MacBook, sometimes the trackpad freezes and then works again, or after the trackpad stops completely, and i get a notification that "No trackpad found" and "Wait for a Bluetooth trackpad to be discovered"
I tried SMC reset, PRAM/NVRAM reset, and reinstalling macOS because I suspected a software problem, but it didn't help me solve it at all.
And this is really an occasional problem, sometimes the screen turns off suddenly while using the MacBook, and when i press the keyboard or touch the trackpad, the screen turns back on and the login window pops up.
The trackpad problem is the most serious and interferes with the use, so i'm writing here to hear from experts.
Thank you for reading! I will be waiting for your good opinion and solution.
