In this guide I explain how to remove and replace the display panel from a HP Compaq nc6320 (nc6300 series) notebook. Most likely this guide will work for some others HP Compaq notebooks, feel free to mention your model in the comments.
Also you can use this guide for:
1. Replacing or upgrading the memory module installed in the internal memory slot.
2. Removing and replacing the keyboard.
3. Removing and replacing the cooling fan.
4. Cleaning the heat sink.
5. Removing and replacing the CMOS (RTC) battery.
STEP 1.
Remove the battery. Under the battery you’ll find two screws (red circles) securing the switch board cover. Remove these screws.
Remove the memory cover. Under the memory cover you’ll find two screws securing the keyboard. Remove these screws.

STEP 2.
Turn the notebook over and release four latches securing the keyboard.

STEP 3.
Lift up the keyboard and place it upside down on the palm rest.

Move the keyboard carefully, it’s still attached to the motherboard via a flat ribbon cable.
Now you can access and replace the internal memory module. This laptop can handle up to 2GB RAM total, so you can install up to 1GB RAM module into each slot. You should use PC2-5300 SODIMM memory.
You can remove the cooling fan and clean the heat sink.
The CMOS (RTC) battery – a yellow battery on the left side from the keyboard connector. If your laptop sets default date and time after each reboot, apparenlty the CMOS battery is bad and has to be replaced. Simply unplug the old battery from the motherboard and plug in a new one.

STEP 4.
In order to remove the keyboard, you’ll have to unlock the connector and release the cable first. Very carefully lift up the brown part of the connector about 2 millimeters. The brown part must stay attached to the base.

On the picture below you can see the connector in the unlocked state. Now you can pull the cable.

Remove and replace the old keyboard with a new keyboard.

STEP 5.
Unplug the switch board cable from the motherboard.

STEP 6.
Lift up the switch board cover with a sharp object and remove it from the laptop.

STEP 7.
Remove four screws securing the display hinges.

STEP 8.
Release the Wi-Fi card antenna cables.
Unplug the video cable connector from the motherboard.
Remove two screws securing the display hinges.

STEP 9.
Remove the display panel from the laptop and replace it with a new one if needed.

You can find a new display panel using the HP SPS part number witch could be found on a sticker located close the video cable connector.

In my case the SPS part number is 413677-001. If you search by the part number here, you can find the whole display panel assembly (includes LCD screen, video cable, Wi-Fin antenna cables, inveter and plastic covers) or just a new screen.

My NC6320 doesn’t switch on any more: it is dead.
Battery is OK and transformer/battery charger is ok to.
What could be the problem?
Thanks for your help

Thanks for this great how-to ! My display would fade if the lid was moved. Eventually i was able to track it down to a loosly fit video connector. I’m sure that the thing would not have survived if i had tried to find the connector myself! Thanks!!

@ jayantha,
Yes, it’s possible but not easy.
Here’s an example of replacing the backlight lamp.

@ MikeJ,
First of all, I don’t think your problem is related to the graphics chip because external video still works fine.
Here’s what you should try:
1. Check connection between the video cable and motherboard. Try reconnecting the cable.
2. Check connection between the video cable and LCD screen. Try reconnecting the cable.
3. If reconnecting the cable doesn’t help, try moving the video cable while the laptop is turned on. If moving the cable affects image on the screen (it’s getting more garbled, getting more lines, or image clears), most likely there is a problem with the video cable. Try replacing it.
4. If moving the cable doesn’t affect image at all but moving the display back and forth affects it, most likely there is a problem with the LCD screen. Try replacing the screen.

My NC6320 screen is constantly distorted and flickering and is aggravated as the screen lid is moved up and down. It started with a vertical line up the screen and got gradually worse. Viewing on an external monitor is however perfect. Is this likely to be a loose connection, a dodgy graphics chip or a problem with the screen itself.
Would be grateful for advise before buying any spares.
Thanks

Hi,
Very handy guide. I do however have a major problem. My cooling fan has stopped working after hearing a little pop and a weird smell. I tried replacing with a new fan but no luck. This may be a problem with the motherboard, if so, what would I need to do to fix the problem and what problem could it be? Thanks

@ noah,
I believe in this model the graphics card is integrated into the motherboard. The graphics card cannot be removed, replaced, upgraded.
If the graphics card fails, the whole motherboard has to be replaced.
Just in case, check your laptop specs again and make sure you have integrated graphics card.
