MacBook Pro constantly thinks its lid is closed?
Ive worked for years on component level repair logic boards etc but this problem has me stumped, the machine switches on but then instantly acts as if the lid has been shut therefore going into sleep mode, the only way I can get the device to work is buy running it in clamshell mode then installing insomnia (if you haven't heard its a program that can prevent your Mac sleeping with the lid closed). I couldn't find an issue with the logic board but I again tested it with a known working one. but still nothing. then I thought they may be sensors etc in the screen so I changed that too but still nothing. What else is there ? I'm stumped. I might also add there is no sign of water damage and the machine passes diagnostics in clamshell mode.
Es esta una buena pregunta?
