I've got a Gateway 600YGR laptop that when I pree the power button the fan comes on and the 3 lock lights blink for a second then nothing. Fan is running but for all practical purposes the computer is off. If I hold the power button down for about 3-4 seconds it will shut down the fan. I have reseated the HD and the memory and the battery. No luck. I don't think it even gets to the reading the HD cause the HD indicator never lights up. Battery is fully charged and I also tried it with the AC charger plugged in. All I ever get is the fan to go on. It was running on Saturday just fine, but this all started on Tuesday. Has anyone seen this problem before?
