Is keyboard problem logic board
Is my problem keyboard, upper case (trackpad/kb logic board), or main logic board?
Started after I replaced hard drive. Keyboard begin to “stutter” - did not register characters when pressed; extreme delay when pressed; registered multiple (usually 2) characters when pressed. Has gotten worse. Over time I’ve noticed:
1. After a sleep, restart, or off/on; it works fine for a while - used to be 30 minutes, now about 5.
2. problems usually first noticeable with Commnd-key or Shift-key strokes (any double key), then gets worse to any key, backspace /delete;
3. on 2 occasions lost cursor/trackpad control & had to restart.
4. on 2 occasions got the kernel message ... white writing on black text dropping down on left side of screen basically saying kernel ?failure/panic/???( dont’ recall exactly) but system was frozen and had to restart.
Does this kernel panic or whatever automatically mean “motherboard?”
What about “upper case” which includes the trackpad logic board?
Reseated all cables in clips:
Keyboard to upper case logic board.
Upper case logic board to motherboard cable
Trackpad to upper case logic board
Replaced entire keyboard with a tested one from ifixit, which included a new keyboard to upper case logic board cable and new backlight cable; and reseating all of the above yet again.
Questa è una buona domanda?
