Only life is caps lock LED which blinks twice - perhaps 3-4 seconds later it repeats. Have tried holding down the WIndows key and the "B" key while depressing the on button. The light by the power input is also working. Having reseated the memory, cleaned the unit of all dust. Wireless light is amber. I hear the fan initially. When I insert a cd I hear the fan again and it "sounds like" it is trying to read the disk.
