I just inherited an old MacBook G3 Laptop.The problem with the laptop is that it always thinks that the cover is closed. All of the documentation I have found on the net say that there is a reed switch that controls this behavior. On my system it actually is a Hall Effects transistor for some reason.
I haven't been able to find this part on ebay or elsewhere (I don't know the Apple part num, just searched for G3 Hall effects). Is there a general purpose Hall Effects transistor (I can get from Mouser etc.) that might work, or do I need a specific replacement?
The markings on the surface-mount component is 13E if that helps?
When I short the bottom 2 legs of the transistor the unit does not go to sleep. If I cant find a replacement I just want to disable this feature. Can I just short the transistor or am I better off using some value resistor across it?
