Chosen Solution
I have a HP Pavilion DV6-2030SA (the Pavilion dv6-nr was the closest model i believe) where when i power up the laptop, i get just the fan spinning and no beep codes or anything, i did get the caps lock and num lock before i started getting nothing, i have had the blinking caps and num lock key issue before but i was able to solve it be removing the CMOS battery and reseating it. I have tried removing all unnecessary devices like hard drive, wireless card, bluetooth module and have tried different DDR2 RAM. I have asked on the HP forums but they said they cant help because i use linux on the machine (what does not affect a potential BIOS issue) and the fact that it is an old model.
I had a similar issue with my Compaq laptop. I ended up trying this method that I saw on youtube where you strip down to just the motherboard, and place the motherboard into the oven at about 200 degrees F. After about 15 minutes, I took it out and pressed down on the GPU to help reflow. Surprisingly, it’s been working fine ever since. At that point I didn’t have anything to lose, so I tried it. https://www.youtube.com/watch?v=JMyxKzyU…
the CCFL back ground lamps are dead now, as all are. this old 10+ years use the VGA port and FN+F4 to use external VGA monitor. does the flash light pointed to LCD show data, yes, then CCFL is dead.
