I have a HP pavillion sleekbook 14 . 2 gb ram. From some days , it has got a problem. Whenever i press the power button it lights up.But the computer doesn't responds.The screen gets no light it is blank.The Caps Lock Button blinks at every 3 seconds.And the F12 Wifi button also lights up yellow. At the end i force shutdown my laptop by pressing and holding the poewer button. If i do not touch the laptop till 2-3 days. it starts and after i shut down , again same problem starts.. The laptop is charging well.
