I first wanted to know what was the maximum memory upgrade I could perform on it so as to see what options I had.  One very big flop which I consider very uncomfortable is that this HP 510 model has only one bank for a memory module thus I could not add say two chips of RAM to have a better possibility of upgrade.

So Checking Online I found this manual which can be downloaded from the following link for the HP 510. I found out that I could only boost this baby up to 1 Gig of RAM so even though I could double its RAM capacity I still was not very content but that was the reality so I had to abide to it.

As you can see from the following diagram the HP 510 has a simple way of upgrading by simply unscrewing this screw as shown hereunder and hola you find the RAM accompanied by its’ neighbouring  Wireless card which you do not need to touch.  Just flip the two notches outwards and the RAM module should flip itself up by its own.  Try not to touch the contacts or any of the surface mount components.

Grab the new corsair DDR2 PC667 SODIMM and slide it through in its place without exerting too much force.  Once done you should here the two side clips make the usual clipping noise and holla the RAM is in.  Just put the back panel in again and secure the panel with the screw.

Flip the laptop up again and check it out.  The OS should theoretically boot at a faster rate.  If you wanna check out if the RAM upgrade is complete just check out the system information through the windows control panel, there it should give you a better view if the memory module has been accepted by the system.

I noticed a drastic increase in speed with just a 1gig module obviously using windows XP SP2..

Model:-HP Compaq NX9005

CPU – AMD Athlon XP-m

The fault manifested only after a certain amount of time so the following tests were performed to verify the symptoms.

1. Powered on with power supply and left idle for a certain amount of time where the fault did not manifest.
2. The next test was to run several tests like opening multiple programs and changing from one program to another like running streaming on Microsoft Media player and browsing a heavy website. Still the screen did not fade away at all.
3. Ran De fragmentation and other heavy tasks to warm up the system.
4. After several tries and a long time after the Laptop was on the fault started to display the symptoms by slowly fading away.
5. Turned off and left to cool down.
6. Turned the laptop back on but this time in safe mode and ran similar tests and the same problem was noticed so the problem is surely with the hardware.
7. Turned on batteries and the problem took longer to manifest since the laptop takes more time to heat up when running on batteries.
8. The next process was to dismantle the laptop and have a better look at the board.

Disassembly procedure.

The first task was to remove all the possible periferals like the hard drive, the ram, the cd rom and keyboard off the way as these are usually clip on stuff that can be remove easily.
THe nect step was to disconnect the screen from the board and unplug the wireless antenna then remove the screen all the way off.

After Doing so the bottom screws were removed and the upper chassis could be clipped off.

Screwed off the mboard screws and remove the board from the lower chassis of the laptop.

On inspecting the board there seemed to be no problems with the video connector and no problems with the pinouts. I looked at the connector with a good lens and this is highly advised since most soldering issues cannot be easily detected especially on these types of boards.

Nothing seemed to be bad with this board so I decided that it must be the screen.
