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.

nevo,
You can buy a brand new screen for HP Pavilion dv4-1028us notebook here.
Here’s official service manual for HP Pavilion dv4 notebook.
You’ll find screen replacement instruction in the manual on the page 84.
By the way, I don’t think it’s necessary to separate the display panel from the laptop base in order to remove and replace the screen.

Hi,
i have these same model of laptop (NC6320) The problem is when i turn on its keep restart every 5 secs… They said motherboard is the problem. Please help me…Thanks
Here’s my opinion on checking out your issue Ryan…. Read these notes FULLY before starting anything… The resolution could be simple, and you don’t want to blow anything away or do anything you don’t need to…
– Things to narrow down the issue.. First, If you’ve got a Windows or Linux CD, boot the system from that, and see if the pc stays up and running for longer. You may want to pull the hard drive out before this test to narrow down the issue. If it stays up, the hard drive or OS may be the issue. Another check is to bring it up and F10 it into CMOS and see if it sits at that for a while (longer than the 5 seconds..). Another issue could be a BIOS problem, (or CMOS battery issue – you could disconnect the battery and see if the issue changes.. this will clear you cmos also, which could have a bad setting – reset to defaults, just in case, and reboot.) and you may want to go to HP and see if they have a flash bios update. (there are a few ways of running them, but the easiest are the one run from inside windows… if available and needed, which may require an OS reload..) Final Option: If it hasn’t got data you want, blow it away and reload, (format the drive in the process). Although, you could just find a USB drive, pull your hard drive out, and boot from a CD and temporarily load a windows OS on the USB drive to do this process.. (I wouldn’t register anything on that windows OS so you don’t bump licenses and shaft thyself though..) (Linux won’t allow you to do the bios updates, I believe, but I’ve been wrong before..maybe under Win for Lin or something…) I had a similar issue and booted my system with a Linux (ubuntu) cd and was able to run from that, which told me moreso that my hard drive OS load was hosed. Another issue could relate to the memory. If the issue still occurs after the other tests, and before doing any destructive tests (blowing away the OS, etc.) you may want to pull all but one memory chip and see if it comes up, if not, swap that chip for the other, and try again. (actually, either way, swap it and boot it again to make sure both work fine) A little due diligence never hurts.. If it’s the motherboard, someone may have a system they dropped and blew out their display, and you might be able to pick it up cheap. (although with an impact, the motherboard may be damaged… you never know. If the OS is the problem and you need the data and have to reload the drive, pick yourself up a 2.5 inch hard drive to USB enclosure and (first make sure you have up to date AV on the second system!) connect the usb drive to a second system, scan it for virus’ and then back up your data to the other PC. If the problem is the motherboard, take the writer of the articles advice and be wary of static, and take off any metallic jewelry (rings, bracelets, etc… anything that might give you a electrical short.), and remove the system battery and power before beginning. I hope this info doesn’t confuse you. I just happened to be looking for a written up script for replacing batteries for my techs to review. Peace and good luck, SA – network engineer

marcus,
Not sure about that. If you change LCD and video cable, it might work.

Hey Man,
Your site has saved me a hours of trying to replace my nc6320′s LCD panel when I couldn’t find anything on HPs site. You’re a lifesaver. Please keep up the great work. I have referred others to your site. Thanks a million.

It is always nice to have nice pics to go along with directions for the imagination impaired. I would like to replace my display with a higher resolution display. Do you happen to know where I can get a direct replacement with a higher resolution?
