PC powers up but does not boot up, nothing but a blank screen and the sound of the cooling fan.
The first step would be to make sure the computer is off, unplug any and all devices from the system, as well as the power cord, then flip the computer over, and remove the battery. With all devices and power sources removed, flip the computer back over, and hold the power button in the on position for approximately 20 seconds (this is what's called a "power reset"). After that has finished, plug only the power adapter into the computer (leave the battery unplugged) and attempt to turn the computer on this way. If this works, then it may be either the battery or one of the devices plugged into the computer that may be causing the problem. If this doesn't resolve it, then the other step that you can take is to try removing the RAM, Hard Drive and Wireless LAN cards inside each of the panels at the bottom of the unit (you will need to have a #0 or #1 philips screwdriver handy to remove the protective panels). Also make sure that you are in a clean environment when handling these parts by hand, as static electrivity can damage the parts and void your warranty, if you have one. Always make sure that you are grounding yourself somehow when handling these parts (usually touching a metal panel inside the computer will discharge any electricity in your body without damaging components, just don't touch an actual component). If you can remove all of the internal workings of the laptop, again, plug only the ac power in, and try turning on the computer. If it works, the computer should begin emitting long beeps, which denotes a "No RAM installed" error. If it doesn't resolve the issue and you don't hear long beeps, then you have a motherboard failure, and should seek the assistance of an authorized HP repair center (most likely through your place of purchase, or by calling HP directly at 1-800-HP INVENT). If you hear the long beeps though, insert one of your sticks of RAM, and again, turn the computer on with just the power adapter. If you see the HP splash logo on your screen, then chances are it's the other stick of RAM that has failed, and you will need to get it replaced. If it doesn't resolve the issue, then switch the sticks of RAM and try again. The idea here is to try and isolate the fault to a single part, and replace that one part. If you are not familiar or comfortable in removing these components, please seek the assistance of a certified technical specialist from one of your local computer stores.
