I have Sony Vaio vgn-bx41xn some of my keys on key board quit working such as e ,f took keys off and clean them but no fix what do you say all you smarter then average bear's. please help I need help badly.
Clean the keyboard with compressed air (blow compressed air in the gaps between keys). This removes some lint and dust.
Shut down the laptop, removed battery and cable for a moment, press and hold the start button for 60 seconds... and replace the battery.. start the lap top.. if that does not work a technician is a must.
