At present it happen to me. While power button been push, the fan are running, the start button is lid.... but just a few second it automatically shutdown with sound `dying'. It will continuous restart rapidly. So before it shutdown, I rapidly push keyboard button until it `hang'. Than I disconnect the adapter and connect back when all electric current is empty. Restart again, push all the keyboard button rapidly until `hang', disconnect power cable.... repeat and repeat until it start well as normal. .
