HP Compaq NX8220 Hang Issue

One of our laptops haven't been functional for a month. It's an HP Compaq NX8220 which is prone to CPU problems. We've had it fixed 2 times already but right now, it seems to look hopeless. I'm not good in fixing laptops since I tend to disregard little details in disassembling things so this is my first time opening the little baby. I got me some coffee and a helping hand from my Wabibear.

It's current issue is that the LEDs blink once, the screen is black and the computer doesn't even beep. People are lucky enough if the first solution can fix it

FIRST SOLUTION:

Perform a hard reset

If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.

1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button,Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.

SECOND SOLUTION: Either you go to a professional (which I do for Laptop issues) or if you have ample experience in CPUs and Laptop disassembling, you might as well check this video.

A manual is good if you tend to go offline and prefer reading more about the laptop's specs but the best way to do it (especially for a novice) is to watch a how-to video while opening the laptop.

Here's a link on the HP Compaq NX8220 documentation (this includes the Disassembling, Specs, Removal Procedures): PDF MANUAL

Another useful link I've searched for had a table of blinking codes which may just help in figuring out what issue the laptop may have.

The good thing about previous HP support is they give sufficient details on what to do and how to fix the laptop. They even provide images in their website so that the customer could easily follow the instructions. Just go here:

Unfortunately for me, I've done most of the troubleshooting steps I've researched about yet the laptop is still non-functional. It must be dying.
