All-in-one HP 3420 new RAM not recognize computer

Have some computers All - in - One HP 3420 I'm trying to upgrade the memory in.

There is that memory, two locations so choose which slot for memory is a no-brainer.

Has started with a 2 GB chip slot added another chip of 2GB to
location B - no joy, computer
recognized only the slot a. 2 GB

Has taken a 2 GB
chip on a second HP 3420 & put it in the slot B
the first computer (just in case I have used the bad memory).
Still no joy.

BIOS is only say 1 Channel memory & only
Recognizing that only channel & 2GB memory
Someone at - it a setting I can verify
or jumpers on the leading edge that must be fixed in order to recognize the double
Configuration of channels?

I would be happy if I can still get the systΦme can recognize the
4 GB, I have in it, either in single or double channel
mode.

In case someone else has a similar problem:

Computer to start

F10 BIOS & GB of information system to check a single recognized memory

Exit without saving changes

When the computer turns off before the reboot, pull the computer branch

After 30 seconds, plug the computer in, turning on and f10 in the BIOS:

computer should now recognise the new RAM

  • HP wireless e-all-in-one B110: HP printer does not not despite all new inks and following the instructions any catch-up

    I followed all the advice given but nothing helped, including the one given on the printer itself, but I just cannot print from my Mac.  Scanning directly from the printer is good, but not from the computer. This problem started only today.

    More than 80 and can not think what else to do! Please can you help me? Thank you.

    Hi Sirodyam ,

    If the printer was working with the previous black cartridge, I think it's a problem with the black cartridge and it will need to be replaced, but I've provided a few steps more, you can try first. Check the date on the cartridge to make sure it is in warranty you have purchased. May be the oldest stock of cartridge.

    If you had the issue before replacing the black cartridge, you could clean the contacts on the cartridge and the vent. Also, make sure the tab on the cartridge. ' Incident affecting an ink cartridge: following print cartridges appear to be missing or corrupt "views for HP Photosmart more e-all-in-one printer series (B210). " Do not take into account the title.

    Here is a document to manually clean the print head. "Incompatible print head," 'Printhead missing or damaged,' or 'Print head problem' displays for HP Photosmart Wireless e-All-in-One Printer Series (B110). Do not take into account the title.

    I hope this helps.

    If you are still not able to print in black, call our technical support at the 800-474-6836 and inquire about a replacement cartridge please.

  • New RAM not working not not on iMac 2010

    Hello

    I have a 21.5 ' mid year 2010 i3 iMac, and, after all this time, it was time to upgrade the RAM.

    I bought 2 x 4 GB Patriot SODIMM PC3 - 10600 1333 MHz 204-pin, by following the instructions in the Web page of Apple memory upgrade (install memory in an iMac - Apple Support).: 4 GB RAM SO-DIMM memory DDR3 SDRAM 1333 MHz. I installed it according to job with factory 2x2gb RAM Samsung sticks. After a reboot, everything worked beautifully for about 6 minutes. The identified computer sticks again and showed me a full 12 GB available. Which was great, since Yosemite + a few browser windows and Spotify only lasts up to 3GB. I have enough to spare. However, it restarted and again and again and again.

    I decided to test only the new RAM and started with the combination of Patriot 8 GB. It froze on reboot and fully started once, but it restarted less than 2 minutes later.

    Result: now I'm back to the original combination of 2x2gb. Always deal with the lack of memory and without understanding what's wrong with the new RAM I bought at Fry's. What about compatibility? Is there an another specification? Of course, I know, there may be a malfunction of hardware, but I would like to address this issue before making another run to the store and risking another model or brand.

    For reference: I've tried it before, but because of the lack of information from the seller, I was conquered by a stick of RAM 1x8GB, which is not supported by my model. So I replaced it with the 2 in question.

    Thanks for any help.

    It is generally recommended to stick with quality RAM to buy from a seller that tests and ensures their RAM to work with Macs - the two most recommended are OWC (macsales.com) and Crucial. They both offer helps you determine which RAM you need and offer the lifetime warranty.

    http://eShop.MacSales.com/shop/memory/iMac/2010/DDR3_21.5_27

    That should be your - sure.

    I'll be back on the RAM for a refund.

  • eMachines EL1850 new RAM not working not

    Hello everyone!

    I wanted to upgrade RAM from 2 GB to 4 GB, so I looked at the label placed on the current RAM and tried to find the best match. I bought and tried 1 x 2 GB Kingston and 2 x 2 GB Corsair (more), but unfortunately none of them worked. After installation and turn on the PC, it was a constant noise for a long time and I couldn't do anything. Nothing on the screen. Then I tried one at a time into the two slots with the same result.

    What's wrong? What I am doing wrong?

    Thanks in advance for your time and help!

    The current RAM:

    UNIFOSA 2 GB GDDR3 - 1333 128MX8 1.5V EP, GU512303EP0202

    I tried (all new) RAM:

    Kingston 1 x 2 GB memory DDR3 1333 MHz Non - ECC, CL9, 1.5V, memory unbuffered DIMM (link)

    Corsair 2 x 2 GB memory DDR3 1333 MHz Non - ECC, CL9, 1.5V, memory unbuffered DIMM (link)

    Motherboard: G41T-AD V: 1.0

    BIOS: P01. B3 (the latest version)

    Upgrades successfully achieved to date: replaced Intel Celeron E3400 with Intel Core 2 Duo E8500

    Fortunately, I found someone who was trying to sell the same Unifosa modules, 2 x 2 GB. They work perfectly!

    I want to thank all the people who have tried to help me!

  • HP Deskjet all-in-one: HP Deskjet 3520 will not print black, period

    OK, I've lost my WHOLE day, searched forums, has done what others have tried, poste posted HP Facebook, doing whatever is humanly possible to get my printer to print in black. I ran the clean printhead, black ink changed TWICE new cartridges, reloaded drivers, reset the default open to the top of the printer and tried to manually clean the head after only 4 hours to do everything I can possibly do to get this junk to print in black. The printer is only a year old and the cartridges are freshly bought from the store. So, tell me what am I missing or is the printer ready to be stoned?

    Hi @ChrisBird,

    Welcome to the HP Forums

    If this does not help still nothing and will not always be the black print, please call our technical support team and request a replacement printer. At THAT TIME, regardless of the warranty, they should be able to establish that the replacement for you. Otherwise, let me know and I'll do my best to help you with a resolution.

  • PhotoSmart 3210 All In One wireless network and does not know how to connect now lost.

    Hi, I have a 3210 all in one Photosmart, and I can't find it on the network more.

    I know that I've done worse of unistalling, reinstallation of the driver HP software and change the IP address of the printer. So I hope that someone can help me with this problem and return to the place where its still visible.

    I have a PC with XP and a Mac with OS 10

    Computers are both connected to the modem wireless cable router.

    The printer is connected to the router via ethernet.

    I can see the printer using a browser and entering the IP address of the printer. I can ping its IP address. The Mac can see the printer, but have installed the correct drivers to see (I think I can handle this, no need to worry about this yet).

    The problem is that I can't see it in the "Add a printer" Wizard on the PC. So I can't add it to the PC.

    I looked around the support of HP and they told me to uninstall the drivers and reinstall them. There was also mention of changing the IP address of the printer to a larger number, but that no longer works. So I went to the automatic assignment of an IP address to the address of the printer. And finally, I've seen mention to unplug the printer and by pressing 'ok' and 'Cancel' all plugging back in. He did a very long installation, but does not solve the problem.

    I searched the forums for a solution and can not find one - so I've exhausted all help (Ive been on the forums enough to know to search before posting a question).

    If Im not sure what to do next. Someone at - it suggestions? I don't really know what I can do to fix this problem: I'm sure it is just a corrupted file or bad setting somewhere I just do not know where he is.

    Thanks in advance for any help.

    For your Mac:

    If you're running Snow Leopard, the driver for the 3210 is compiled.  Open the applet Print & Fax under system preferences, then press [+] to add the printer.  For other versions of Mac OS, download the driver from here and run the installer.
     
    If you continue to have problems with the Mac, reset the printing system Mac and repeat the instructions above.  Information about resetting your Mac printing system can be found here (http://support.apple.com/kb/HT1341)

    For the PC:

    The 3210 is on the network, we will try to add the printer manually. First verify that you can access the printer's internal web page by accessing its IP address or host name.  You can find the IP address and the host name by printing the network configuration page.

    Here is the sequence of manual installation of the printer driver for XP:

    1. click on the 'Start' button--> printers and fax machines.
    2. under print jobs, click on "add a printer".
    3. click on 'Next' on the Add Printer Wizard window.
    4. Select "local printer attached to this computer. Deselect "automatically detect and install my Plug and play printer." Click "next".
    5 under, select a Printer Port option, select "Create a new port" and choose "Standard TCP/IP Port" and click "Next".
    6. in the "Welcome to the Add Standard TCP/IP printer port Wizard" make sure that the printer is turned on and connected to the same network that your computer is connected to. click on the button "next".
    7. under "Add Standard TCP/IP Printer Port" enter the host name of the printer. You can also use the IP address of the printer if it is static. Click 'Next' and then click 'Finish '.
    8. now select HP in the manufacturers list, select your printer in the list of the models of printers and click the button "next".


    9. If you can't find your printer, you will need to find the installation CD and use the 'Disc' option to select one of the files hp*.ini. You can also select another model of the same type HP printer.
    10. Add the name of print spooler, and then click "next".
    11. click on "next".
    12. click on "Next" and "Finish."

  • HP6520 ALL IN ONE PRINTER: BLACK INK WILL NOT PRINT

    I TRIED ALL THE PROPOSED SOLUTIONS.  NO WORK FOR ME.  I HAVE TRIED SEVERAL TIMES TO RUN THE CLEAN CARTRIDGE HEADS.  SAME RESULT (WASTED A LOT OF VERY EXPENSIVE INK IN THE PROCESS).  ANOTHER USER HAS SUGGESTED TO USE SOLVENT TO CLEAN A CLOGGED INKJET PORT.  I DIDN'T KNOW WHERE REPRESENTATIVE HP APPROVED THAT.  THE PAGE OF DIAGNOSIS THAT PRINTS AFTER HAVING CARRIED OUT THE SYSTEMATIC CLEANING HEAD PRINT BLACK TEXT, BUT THE BOX FOR BLACK PRINTING IS TOTALLY WHITE.  IS THERE ANOTHER SOLUTION TO TRY?  Help!

    The printhead on the HP Photosmart 6520 is not designed to be removable by the user.  While you can find messages with information on the withdrawal of the printhead for soaking, it's really not recommended.  If you decide to do this don't forget to read the entire thread, these discussions often end with a printer damaged due to damage or damage to the encoder system, electrical connectors which can make the printer unusable.

    You may have already taken the steps of troubleshooting in the paper here, if not go through each of them in order.  Check the vents on the black print cartridge and that it sits correctly.

    If the above does not solve the problem you could try manually to clean the printhead, as described in the post here for a different but similar printer.

    Note that the printer uses a mixture of color and black inks to print a diagnostic page.  This is so that the information can be read even if black or one or more colors do not work.  Although it may seem from this page your black works that is unfortunately not.  You can simulate this by selecting "Photo paper", as the media type in the driver, it would force the printer to use the same color ink to print black text.

    Hello

    Sorry, but the printer is not supported on Windows Vista 64-bit.

    64-bit support is only available in Windows 7 or later operating systems.

    You can find the printer specs below:

    Vista 64-bit is not supported.

    You must upgrade your operating system to a later version to use instead an OS 64 - bit, Windows Vista 32 - bit to insall or replace it with another printer, compatible with your operating system.
