Latitude D820 does not boot

This question has suggested answer(s)

Hi,

My latitude D820 does not boot. When turn on the laptop, it powers on, the number lock light turns on but the screen stays black always.

Power on with  "Fn" press down, it performs some diagnostics, it passes the "screen check" (I can see the screen red, blue, white, etc) and after it, just blocks doing a forever sequence of :

1-Three lights blinking simultaneously, three times with three beeps

2-Three lights blinking simultaneously, three times with three beeps

3-Three lights blinking simultaneously, three times with three beeps

4-Three fast beeps with the three lights lighting up sequencially (capslock, numlock and scroll lock)

5-Go to step 1 and repeat again forever.

Does anyone give me a clue of what is going wrong with the laptop?

 

Many thanks for the answer, kind regards,

Helder
