My battery on my compaq presario cq56 is not recognized. It's not even an icon for it. Hp support assistant said trying the update of the bios battery. I can't find to download... Help, please!

My battery on my compaq presario cq56 is not recognized. When I ran the test on HP support assistant, he says take the battery off and then powered off and that did not help. He said to ensure that the latest version of the BIOS battery has been installed but I can not find how or where to do... someone know how and if it is the best thing to do?



This document includes the steps of research, download and installation of updates to the BIOS (Basic Input Output System) or ROM (ROMPaq) for your HP or Compaq laptop.

    Can someone help me please, I don't know how to use a computer I was googlen 4 days! When I opened my computer it always tells me that the file is damaged and unreadable. Please run the Chkdsk utility... I searched my computer for "chkdsk utility" and can't find that. Help, please!

    From what you say, you are probably unable to start Windows.

    In this case, when you start the computer, keep tapping the key "F8" on the keyboard until the Advanced menu comes up. Then choose "Safe Mode".

    You will see something like your ordinary, here to enter office "chkdsk volume: /f" (replace with your hard drive volume, in most cases, it's 'c') at the command prompt.

    For reference:

  • Compaq presario cq56 primer not.

    Model: Compaq Presario CQ56-219WM

    I've had the computer for only less than a year. When I press the power button, the computer starts, appears red 'Q', then 'hangs' on a black screen with an underscore flashing. I ran the diagnostic tests available and everything SEEMS fine, but it still does not boot past the black screen. Tried a hard reset, still no luck.


    Assuming you are using Windows 7, try the following.

    If you do not, use another PC to create a Windows 7 recovery CD.  Download the ISO relevant among the links below - if you are unsure, your laptop is listed as having a 64-bit installation...

    Windows 7 32 bit

    Windows 7 64 bit

    You must use an app like ImgBurn to burn the ISO to a CD - a guide on the use of ImgBurn to write an ISO on a disc is here.

    Demarrer start from the rescue CD, select repair your computer and choose the command line.  When this charge, enter the following commands and press on enter after everyone – including spaces as shown.


    bcdedit/export C:\BCD_Backup


    Boot CD

    BCD attrib s h - r

    Ren c:\boot\bcd BCD.old

    Bootrec /RebuildBcd

    Bootrec /fixmbr

    Bootrec /fixboot

    Remove the rescue CD and try to restart now.

  • Compaq Presario CQ56 "IE not connent Web site.

    In 'safe mode' I can access websites, but in my CQ56 Notebook PC work normally connets wireless internet, but provides only messages saying "IE cannot connect to the Web site.  What adjustments are necessary?


    You are welcome

    I think you're right and that it is a security issue.  The most likely cause is a form of misconfiguration or bad updates related to your security software.

    What I would say is completely uninstall your current security software (if you are using a version, make sure that you have a record of any activation key, you need and a way to reinstall the software later).  If it is a Norton product, download and run the relevant "removal tool" from here to perform the uninstall.

    Once the uninstall is complete, reboot the laptop and check if you can connect now - choose only a 'safe site known' (IE Microsoft or HP).

    If everything works well, reinstall your security software, restart the computer and check if you can always connect.

    Let me know.

    Kind regards

  • 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.

  • 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.
