I HAVE A COMPAQ X1000 LAPTOP AND WHEN I USE CRUCIAL.COM TO SEE WHAT I HAVE FOR MEMORY IT SAYS I HAVE 768 MB INSTALLED WITH 2 PORTS BUT WHEN I CHECKED THE PORTS I ONLY HAVE 1 MEMORY PORT

This laptop has 2 x memory slots.

Each memory slot can hold DDR PC2700 with a maximum of 1GB per slot.

1GB, 200-pin SODIMM, DDR PC2700 memory module

Yes you can. You can increase the memory up to 1GB. If you are going to keep the memory inside then you should buy a 512 MB memory card, making your computer run on 768 MB of memory. If not then replace it with a 1 GB memory card. Remember, this computer can only support a maximum of 1GB total memory. The price depends on the memory module. The higher it is, the higher the price will be. Go to your local computer store for the price.

Try a different brand of memory.

It is unlikely you can do anything with the memory you have to fix this problem.

The memory has the same specs as what another manufacturer recommends.

Be careful buying from auctions as they MAY be gradeouts. Always make sure you can return the product. Crucial has these for about $114 for your machine as an example.

256MB = .25GB
512MB = .5GB
768MB = .75GB
1024MB = 1GB

Your HP Mini takes this type of memory:
DDR2 PC2-5300 • CL=5 • Unbuffered • NON-ECC • DDR2-667 • 1.8V • 256Meg x 64

You can find the memory type for your computer here:

This laptop has 2 slots
Each memory slot can hold DDR PC2700 with a maximum of 512MB per slot.
So maximum memory supported is 1GB.
If you install more memory there is a high probability it will not be recognised.

You can get more information and order memory from the link below:

OK, according to Crucial.com your RAM does need to be installed in matched pairs.

Here is a link for your computer information:

If you get another 512MB module and install both pair, it should work well.

This laptop can support up to a max of 1 GB of RAM , so if you buy 1 stick of 1 GB of RAM you need to take out the 768 MB and just put the 1 stick of 1 GB RAM, or your other option is to buy a 256 MB of RMA so your computer will still have a max of 1 GB of RAM and that would be cheaper and you can still use your old RMA on your laptop , this is the lin for the complete specs of your laptop http://www.dealtime.com/xPF-Compaq-Refurbished-COMPAQ-P4-M-1-8GHZ-256MB-30GB-14-1-TFT-CDRW-W-XP

It may be the problem with driver. Your OS may not contain the proper driver.Like in windows service pack 1 do not recognise some camcorders. either upgarde to service pack 2 or download proper driver from manufacturers site

The second memory slot is under the keyboard.
Remove two screws at the bottom.
Move downwards 4 switches at the top of the keyboard betwwen these letters (es-f1, f4-f5, f8-f9, f12-del) and raise it from the top.
Be careful not to remove keyboard ribbon-band.
There it is!!!!
