Question about HP Pavilion dv4000 Notebook
Pressed power button, power lights come on, but nothing more happens. it's like it's dead with the front and top power lights illuminated.
Try this solution :
1. Disconnect the AC Adapter.
2. Remove the Battery.
Note : Please see that there are no external devices or cables connected to the Notebook.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook.
Additionally, try removing and reinserting the RAM sticks by following the instructions listed in page number 119 of 266 :
If the issue repeats, try connecting the Notebook to any Desktop Monitor and press the FN and F4 key so that the display will transfer to the desktop monitor connected.
If there is no display on the LCD of the Notebook or on the Desktop monitor connected, issue can either be with the Graphic Card of the Notebook or Motherboard itself.
I am sure these instructions are helpful.

I had the same problem with the HP Pavilion dv4000 where the lights would come on at power and the hard drive light flicker, then nothing. I went through the same procedures outlined here to no avail.
What worked for me and maybe there is a loose connection or glitch in the BIOS, but when I powered on the laptop I squeezed the lower left side of the laptop next to the touchpad from the top and bottom. Voila, I saw my Windows logo pop up. I then decided to see if messing with it would cause any reaction and it did. The progress bar on the Windows start up screen froze until I squeezed the left side again and it continued.
I am in the process of updating the BIOS and see if this resolved the issue. If not, possibly the RAM is loose or needs to be cleaned since the modules are near this area of pressure I apply.
