Compaq Presario CQ56-110US: Will Compaq CQ56 8 GB RAM support?

According to the Compaq Presario Maintenance and Service of Guide matrix on page 2 (, my Compaq Presario CQ56-110US laptop supports up to 8 GB of system memory, but by following a few lines to the bottom of the guide, it lists the configuration information that tops out at a total of 4 GB. If I remove the 2 existing memory chips (1 GB each) and install two 4GB chips, my laptop will support the upgrade to 8 GB?

Compaq Presario CQ56-110US laptop

Processor Intel® Celeron® 900 (2.2 GHz)

Supports dual channel DDR2 800 MHz memory

Thank you




Unfortunately, your model will not support 2 x 4 GB of memory.

This is because it is equipped with an Intel Celeron processor, your laptop is the chipset Mobile Intel GL-40.

This chipset only supports a maximum of 2 x 2 GB memory.

By the way... 2 x 4 GB memory DDR2 would cost a lot of money.  It was the cheapest I could find.

  • I have a compaq presario cq56-115dx notebook pc and I wiped the hardrive without knowing


    I have a Compaq Presario CQ56-115DX laptop running on Windows 7. I wiped the hardrive without knowing what would happen, and now when I turn it on it has a black screen with a white dash flashes. I was wondering if there was a way to solve this problem.

    Thank you!


    You will need to order a set of recovery disks.

    Or if you can read your Microsoft W7 product key you can make your own windows 7 installation disc.

    Here's how:

    If you can read the Microsoft windows 7 25-character product key, you can download simple Windows 7 ISO files to burn on a DVD for the version of windows that is installed on your PC, and which is listed on the Microsoft COA sticker on your PC case.

    Burn the ISO with the option to burn the ISO on your DVD burning program and burn it at the slowest possible speed that will allow your program. This will create a bootable DVD.

    Or use the installation of Windows 7 USB/DVD tool to compile the ISO file that you download from Digital River. Link and instructions below. You need a 4 GB flash drive to use the USB compilation method.

    Use 25 characters on the PC product key to activate the installation.

    The key will activate a 32 or 64 bit installation.

    Then go to the support of the PC and driver page to install the drivers you need.

    Link to downloads ISO of W7 is below.

  • Compaq Presario CQ56 - :(wireless Internet problem

    Hey everybody,

    So I just joined here to see if anyone can help with my problem, because frankly, I'm out of options now about two weeks asking friends and colleagues and searching the Internet for answers to similar problems. I tried twice with the information I found on this site for quite some time and it does not work for me!

    In any case, I have a HP Compaq Presario CQ56 laptop. It has been implemented correctly when I bought it, everything worked perfectly. I managed to catch a virus that prevented me from even turn on my computer (which is strange, because I'm not a fool with computers, and I know what not to do/download sites to visit), so I had to restart my computer to stock, I used my Windows 7 disc, partitions formatted and installed windows again.

    Now, for some reason it doesn't connects wireless Internet. It connects when I have an ethernet cable connected, but it is not all networks, as shown in this screenshot:

    (And also here's a cute Bunny for your pleasure)

    So you see my problem it is very frustrating. I don't know what is the cause, but I guess it must be a driver problem? Which is why I write here, if this is indeed in the wrong section, please accept my apologies.

    Here is an another screenshots that can help, just in case:

    If someone could shed some light on the problem for me, or even to resolve, I'd be very grateful it is extremely annoying. As I said, it works fine when I have my laptop connected to the internet, when I'm in College, but when I come on a weekend, I can't put my laptop, because I only WiFi at home.

    Thanks for reading

    Hayley R

    You are the very welcome, Hayley.

    The problem is that the needs of the wireless (network controller) one adapter driver installed and here is the link for the driver you need.

    Once you install the driver above, the wireless should work just fine.

    Best regards
