1) NO fan noise or HDD noise could be heard,
2)screen is blank
3)Tried hard reset of power- removed battery, tabbed power button for number of times without power supply for +30 SEC each, then plugged in, inserted battery and pressed power button. Just "power ON light" lights up and automatically turns OFF.

Please Help!
