I found this one on Amazon.com & will work for you, there are a few to choose from at different prices. Just cut & paste this and put in the Amazon.com Search Box: NEW AC Adapter Power Supply for Compaq Presario M2000 V2000 V4000 V5000 by Systems Integration Business

Not sure, but I bought it to work with E6320. This was listed as a model it should work with, but I never got it to work at all.

I bought them for my HP. When I was looking to upgrade the ram in my laptop I opened the back of my computer and looked at the ones that were already in there in order to get the correct ones. I can't tell you for certain that these will fit a Compaq. I hope this was of some assistance to you. Trish

I would go to HP's site to verify. I use this model in MFSYS25 Intel modular server. Intel lists it as a compatible device on their site.

No. Look at the bottom of the description.*****Not Compatible with Pavilion DV4-4000 Series and up,

The picture shown is incorrect for your Presario cq50-101la. You need to use DDR2 SDRAM with a Speed 667.0 MHz and a Form Factor SO DIMM 200-pin. You can find the correct picture on this link: http://www.cnet.com/laptops/compaq-presario-cq50-101la/4507-3121_7-33324870.html.

Go to www.crucial.com and they will have a system compatibility program, just enter the make and model into the form and it will show you exactly what is compatible. It is an easy access program and you will know for sure what part numbers will work.

Yes it is compatible ! Here is a site that specifies what RAM is needed for that computer. It looks identical to what is offered on Amazon. http://www.crucial.com/upgrade/HP+-+Compaq-memory/HP+2000+Series/HP+2000-239WM-upgrades.html

According to the Asus website it is. Need to have a Bios version of 0402 or greater.

I honestly don't know, it works fine on my Presario Laptop CQ056. Hope it helps you.

Although I used it in an HP printer as well, I agree with afinadm, and further memory is generic . . . if your v4000 uses the 144 pin, etc. sticks it should work fine.

The best way to answer this accurately is with the Compaq website and the specs of your laptop's memory capacity and requirements. The brand of memory will work but you need to check the speed and size compatibility

Iam not sure. I usually just look at what kind of models that is listed will be compatible with the laptop that I have.

Sorry, but I would have no way to know that. If the pinout is correct, and the specs on the memory are correct, I would expect it should work.

I couldn't say with certainty if it will fit a Compaq. I had to shop around for weeks. If you have the old battery look at the numbers and the connection. It takes time but it will be accurate.

Should work as Akshay said. But to be sure download the free system scanner from crucial.com, that's what I did and just copied and pasted the ram type and compared prices here on amazon.
