I was doing some drawing tonight on my Macbook Pro using my Wacom graphics tablet. I left the machine running when I had my dinner and when I returned I was unable to wake the machine from sleep.
After trying the keyboard, mouse and power button to wake the machine I unplugged the tablet and tried the power button. This time the machine started a long pause on a blank blue screen.
When the machine started I noticed the battery had been half depleted and the CPU/GPU were both at 65c.
The backtrace error report seemed to indicate the bluetooth module which is odd because I wasn’t using any bluetooth devices.
