This particular laptop will not support DDR3 Ram (4GB Module). You will need 2 2GB DDR2 modules to obtain 4GB

@ Arpad,

Currently I have 2 * 512 MB RAM. I will upgrade to 4 GB.

What would be the difference between the following options?

512 MB + 4 GB – in this case I wouldn’t have to take apart the laptop; I would have to change only the easily accessible panel
4 GB – I would take out both modules and insert only 1 piece of 4 GB module
2 GB + 2 GB

Any of the above would do? Would the end result be the same?

I doubt that this laptop can support 4GB RAM module in one slot.
I think your only option would be installing two 2GB RAM modules.

512 MB + 4 GB probably will not work at all. Laptop might start properly but will not see all memory.
4 GB probably will not work at all.
2 GB + 2 GB I think the only option.

@ Fred,

I broke the ribbon cable retention tab!! The larger one. Can anyone recommend where I can get a replacement?

Is it broken really badly.
Here’s something to try.
Insert the cable back into the connector. Place the retention tab back in place the way it should be. Secure connection with sticky tape.
Something like I explained here: http://www.laptoprepair101.com/laptop/2009/11/17/fix-broken-keyboard-connector-on-laptop-motherboard/

Hi. I had 1 GB of ram in my laptop (2 x 512mb), and when I got a 2gb ram stick and replaced one of my 512mb sticks, I was expecting either 2.5gb of ram or 512mb of ram. I actually got 1gb again. I have tried both slots and got the same result. Any ideas?

Hello,

“Fred Wilson mentions adhesive and reglue. Does that mean, that I can’t clean the keyboard underneath. I have the same problem with letters, typing themselves and would like to clean the keyboard.”

Solution is easy: nc6400 has an issue which cause this behaviour, All You have to do it put sheet of paper under keyboard. It works for me and i like my laptop again

Hi, I just got a HP Compaq NC6400 PK130060200 for my laptop but when i decide to change it i realise that mine is PK130060100 and the ribbon that connect the system board on it is much narrower and the one i got PK130060200 is much wider so i can’t insert it to the ZIF connector.
