The trackpad's click often fails during normal use.

It fails when the computer is used in a horizontal position flat on the table, but when the computer is tilted at a 45º angle the click starts working again.

The computer has gone to sleep twice in the middle of use.

Now every time I wake the computer up from sleep, the computer's screen flashes green or with a pixelated image, and the trackpad and keyboard do not work, so I have to force shutdown and do an SMC restart.

I was using El Capitan when the problems started, and now I have updated to High Sierra with no improvement.

I used cocnutBattery to assess the battery health in case of swelling, but it says the battery is completely healthy. Apple diagnostics also couldn't detect any problem.

I have tried the NVAM and SMC resets many times to no avail.

Any suggestions?

  • Check with coconutBattery - but it does sound like it's swollen. – Tetsujin Nov 27 '17 at 15:18
  • I would suggest you run Apple Diagnostics and see if it reports an issues. Check here for more information on Apple Diagnostics: How to use Apple Diagnostics on your Mac – Jake3231 Nov 27 '17 at 15:36

  • coconutBattery cannot tell you if your battery is swelling. This has to be done via visual inspection. – Allan Nov 29 '17 at 16:29
