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.
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.
Turn the notebook over and release four latches securing the keyboard.
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.
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.
Unplug the switch board cable from the motherboard.
Lift up the switch board cover with a sharp object and remove it from the laptop.
Remove four screws securing the display hinges.
Release the Wi-Fi card antenna cables.
Unplug the video cable connector from the motherboard.
Remove two screws securing the display hinges.
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.
