MacBook reboots after waking from sleep mode
MacBook Core 2 Duo; 1.83 MHz; 2.256GB RAM; OS 10.6.3
MacBook goes into restart after going into sleep mode. It does not appear to be an operating system problem since the problem occurs when started from an external disk and independent OS. PRAM and SMC resets have not helped. Operating from battery or power adapter results in same behavior. No other problems are apparent during operations.
Is this a good question?
