In my MacBook Pro, the batteries keep dying after about 30 days (2-3 replacements installed so far) and the WiFi keeps disconnecting after about 10-20 seconds of connecting. I’m thinking the I/O board and AirPort card may need to be replaced. Am I off-base or could it be something else? I have also replaced the MagSafe charging cable already. Any tips and info is appreciated! Update: Charged 15 hrs, turned off.
