I just moved back to Vail from TX. While listening to to spa music on my Acer, the computer just went black screen on me. I never removed the charger so the light is blue but I don't see or hear anything from my Acer.
During the times of unplugging, did you take the battery out after you unplugged it? Then hold the power button down for 60 seconds. You may want to take your power cord, after you have unplugged it, and if it will come apart in two parts, go ahead and separate those two cables while you hold down the power button. Then put it all back together. Let us know!
