   HP Pavilion DV6408NR. The problem is due to the nvidia graphics chipset becoming slightly unseated from the mainboard.
   
   Remove the RAM access panel, you will see your ram chips and above these is the wlan controller and directly beside it a small black chip that says Nvidia. This is your graphics chip. We want to leave these COMPLETELY exposed at all times (you might as well get used to just not having the panel on for this fix).
   
   From a cold start (i.e. the computer is completely off and unpowered) boot once, wait about 5-10 seconds. This will allow the motherboard to build up some heat... If you touch your graphics chipset you will notice it's started to warm up. Now go ahead and power the computer down, it's not going to boot on this attempt, but we got the solder warm.
   
   Again power the computer on, and wait a few seconds. This time you should hear your fan magically kick on (assuming the fan is still working, as it is in mine). AFTER, and only after you hear the fan rev up to full speed, begin applying FIRM pressure with your index finger to the gpu (the black chip that says nvidia). Just wait a few seconds and voila, your HP POST screen magically appears.
   
   I've had to do this with this laptop for nearly 2 years now. It never takes more than one to two tries to get it to start up. A word of warning: Do NOT close the screen, you only have about a 5% chance of it actually coming back on when you open it back up.
