First and foremost it is important to remove the battery and any slot in memory cards that are present.  Remove also any Game in the drive.

The Guarantee seal will need to be remove since two screws are beneath it so start with these four screws which are present in the battery compartment.  Two other screws are present on the other side of the PSP.

The next screw that needs to be removed is the external screw just next to the side bar code between the speakers.

Once these are removed the rear panel can be unclipped.

Now the screen can easily be seen but to remove the LCD screen you must first un clip the button bar which resides just below the screen.  Use a screw driver to un-clip . There is no need to remove the cable from the main board.

Once done unclip the screen with the same screw driver and slowly remove the two cables.  Before you do this you need to first lift the connectors slowly because they can be snapped very eaily.  Once this is done the screen is released and can be changed.

The same procedure can be repeated reversly to close the PSP back.

Look at the images for a better view of the procedure.

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..
