Can I disable a broken reed switch / hall sensor
My MacBook Pro is having sleep issues that seem related to the hall sensor (often referred to as the reed switch), and I would like to know if I can solve the problem by physically disconnecting the sensor.
[A detailed description of the symptoms is below.]
I'd be perfectly happy if I could simply sleep / wake the machine "manually," with the clamshell open, and closing or opening the clamshell as appropriate without affecting the machine's sleep state. Is physically disconnecting the hall sensor possible? If so, would it accomplish this?
The machine will suddenly go to sleep while being used (and with the clamshell open). That is the big problem.
Also: if I close the clamshell with the machine awake, it goes to sleep. Then after a few seconds it seems to wake up. The sleep indicator light starts blinking rapidly (rather than pulsing slowly).
If I sleep the machine with the clamshell open (e.g. by selecting "sleep" form the Apple menu in the Finder), it will wake up after I close the clamshell.
Diagnostics / system info:
The main tests in Apple Hardware Test and Apple Service Diagnostics (both OS and EFI) show no issues, aside from a press of the battery indicator light button not being registered by the SMC. One of the interactive tests in ASD intermittently registers a problem with sleep/wake and the clamshell.
I have an SSD in the main drive bay, and I replaced the optical drive with the hard drive that came with the machine (using OWC's "data doubler" bracket). This problem did not crop up until many months after I replaced the optical drive with the hard drive.
