Have you tried an SMC reset and PRAM reset?
SMC:
1) plug in MagSafe
2) press and hold Shift+ctrl+option(alt) AND the powerbutton
3) hold it for 5 seconds and look at the orange light at the magsafe.
4) release and wait for it to turn green and back to orange
5) press the powerbutton again to power on the machine
NVRAM /PRAM:
1)right after pressing the powerbutton to turn on the machine , press and hold the following.
2) option(alt)+cmd AND P + R
3) release after the machine reboots (after hearing the sound)
