Hello team HP,

I use a Compaq Presario CQ40 - 144TU, Windows 7 64 bit. I want to upgrade RAM. But I don't know exactly the frequency of the ram to be updated. What is 667 Mhz or 800 Mhz?  which is more suitable for my laptop?

Is it possible for me to upgrade to 6 GB. In the main location 4 GB and 2 GB in the secondary location.

Thanks in advance.

Hello

You machine has 2 GB of RAM in two slots curently (1 GB each)- 2048 MB (1 x 2048 MB):

http://support.HP.com/EE-en/document/c01573098

It supports 8 GB (4 GB) total. Yes, you can switch to 6 GB. RAM are cheap now, you have to throw away two 1 GB parts - account up to 4 + 2 or 4 + 4 won't cost you much more.

Please use manual #13 to the following list (Compaq Presario CQ40 Notebook PC - Maintenance and Service of Guide)

    No he is the type of hard disk and how it connects, and you have this kind

    And an SSD is like this:

    See the difference in the interface? It is a kind of hole plug round/square of the thing. I could go on technically on different types of storage controllers and how to optimize the speed of SSD, but the different plug-ins is a killer deal from the outset.

    On what you can do if you want to speed up the hard disk, performance is to find a 7200 RPM hard drive PATA (top photo), which will be much faster than 4200 or 5400 RPM nature, which is probably what has / have. I actually bought a supply of 60 GB 7200 RPM IDE/PATA drives of the laptop that I use in my hobby of refurbishing older laptops. I don't want to sell to a member of the Forum HP (kind of conflict of interest), but I can probably direct you to the place I got them if you will send me a PM.

    My best real advice is that your laptop if it were a car would have the right to have "Antique" plates and is actually just a little newer than some of the 'old' portable in my "vintage" collection The market is very respectful of the buyer and you can get a laptop that will run rings around you for maybe $300 these days and will allow you to use a modern OS with a semblance of security. I don't think not that your could run anything newer than XP.

  • You think it's wise to upgrade my Satellite to windows 7

    Hey guys good night.

    I'm curious to know. All do you think it is wise to upgrade my computer satellite phone to windows 7.

    If so, I would be able to install the utility programs ecopackage and pvat so I can use once more my eco utility and pc health monitor features.

    I'm considering upgrading, not otherwise expensive and I was told that the laptop runs much more smooth especially since it is a year old and probably played virus he part.

    Also, or is - anyone know of any problem seems to have been experienced with the upgrade of the satellite series windows 7 (want to do a clean update).

    Hello

    In my opinion the Windows 7 is the best OS that has been released by Microsoft.
    Of course it takes more material resources as the beginning of Win XP (which was really good), but the fact is that Win 7 is the future and all other systems are past.
    I would recommend Win 7. I changed my two notebooks to Win 7 and everything works great.

    The VAP and ECO utility are released for many Toshiba laptops, so if your laptop series wouldn't not contains such tools, I recommend checking out the tools available for other series.

  • Can upgrade you XP to 7 with the upgrade of student in VMware?  I can't make it work...

    Hey guys,.

    I'm having a devil of a time with this... I have XP on the partition boot camp, as well as a computer virtual created from it.  I just purchased the upgrade to the Windows 7 home MS student, burned the ISO to a bootable disc, and now I'm stuck.  I have a MBP 13.3 (5.5) running Snow Leopard and VMware Fusion 3.  I tried to start my computer the DVD, only to have the installer of Windows 7 tell me that it doesn't have the correct drivers.  Well, then I start completely in Snow Leopard, open to the top of my bootcamp with merge partition and I can't seem to start from the DVD here, or in the virtual machine either.  So I'm stuck, what am I doing wrong / is there a way and it works?

    Thank you!

    Win 7 coming to be superimposed on a XP installation isn't a good idea.  You are better to destroy your Boot Camp partition and install a clean copy of 7, Ditto for a new virtual machine in Fusion.   Keep in mind Apple has not released the Boot Camp for Win 7 drivers yet, but the plan at the end of the year.

    For the installation of an upgrade disk, you can do this by entering is not your product key during the installation and the next article Paul Thurrot Clean install Windows 7 with upgrade media, if you have only one disk to upgrade you will need to interrupt the use of your XP machine by the upgrade license.

  • Compaq Presario CQ5300Y desktop PC - memory upgrade

    Hello, everyone! I hope you are all well.

    I have a desktop PC Compaq Presario CQ5300Y, to which I would like to upgrade the memory.

    The product specifications indicate clearly that the motherboard, a M2N68-(Narra5), 2 x DDR2 memory media. (In addition, the amount of installed memory is 2 GB.)

    The product specifications, in the information section of upgrade memory also mention the following:

    -----------------------------------------------------------------------------

    Dual channel memory architecture
    Supports two DDR2 DIMM (240-pin)

    Supported DIMM types:

    PC2-5300 (667 MHz)
    PC2-6400 (800 MHz)

    Memory non - ECC, unbuffered
    Supports DIMM DDR2 2 GB modules
    Supports up to 4 GB * on 32-bit PCs
    * 32 - bit operating systems cannot resolve a full 4.0 GB memory.

    -----------------------------------------------------------------------------

    I'm clear (with what the article said) I have only available two DIMM DDR2 2 brackets.

    "What confuses me is the statement" ""supports 2 GB DDR2 DIMM '. This is the reason for my question.

    "Supports 2 GB DDR2 DIMM" means that I have to use 2 GB DDR DIMM only, which means I can only go to 4 GB? Or could I use 4GB DDR2 DIMM, which breaks the barrier of 4 GB?

    In a few words, I would like to - at least - 8GB (assuming that I find two modules DIMM DDR2 4 GB). Would it be possible to have the above configuration?

    It is important to mention that the PC is running a 64-bit operating system.

    I would appreciate the attention he can draw on this issue.

    Best regards.

    I can play CDs, but when I put any kind of DVD in there, it does not read anything.

    Hi João,.

    you have a problem with your DVD player? I suggest the following:

    Remove the disc in the "device manager" Windows, let windows reinstall, test if it works. If the same problem persists contact an ASP in local (certified partner)
    because your drive is probably faulty then your machine should be checked by a qualified technician.

    My HP Compaq presario CQ43 has 2 GB of ram. I want to get 8GB. It is 64 bit and it's hard to run most programs because of the ram being such a small size. It will support 8 GB of ram? If I take out the old 2gig and put 8 gig will perform best?

    According to the manual, yes it can accept up to 8 GB memory DDR3-1333 SO-DIMM. See this video on: 33 in there where is flush with the memory. This technology never removes the memory but you just spread the retaining clips and remove and then follow again. See the second video.

    You have 2 slots, so you need the modules of 2 x 4 GB like this:

  • Compaq Presario CQ56-115DX: can I upgrade to Windows 10?

    I have a laptop Presario CQ56-115DX, bought October 2010 (5.5 years) and running Windows 7. Considering the free update of Windows 10, I am concerned about the graphics card (ATI Mobility Radeon HD4250). I can't find an answer consistent and simple as to if it will work with Windows 10. Some sources claim a flat No., while others say No Problem, and still others say it's possible, but I'll have to pass through many creoles, manual installation of upgrades/downgrades of device drivers before, during and after the upgrade of the OS.  Maybe a BIOS update, too.

    So, can someone give me the history of right? When all is said and done, I at least will be no worse off as I am today on Windows 7, for graphics and video capabilities? I do more than very light animation and card games - no heavy action or stuff VR Council. This laptop has the power to do this kind of things anyway. If there is clear instructions somewhere for the manual steps that must be done before pulling the trigger on the upgrade of Win10, I can follow them. I don't want to risk in bricks during the upgrade! Supposedly, for 30 days after the upgrade, I can return to Windows 7, but it's no good if I can't get on the machine in the first place.

    I realize that this machine is getting quite long in the tooth, so a hardware upgrade (if that's even possible) is out of the question. If I have to stay on Windows 7, I'll run that, until the support is gone and then switch to Linux or something (maybe dual boot) until the material finally die.

    Are there any other known folds in a Windows 10 upgrade, in addition to the graphics? I've seen complaints about wireless, keyboards, optical drives and other things does not work properly after the upgrade.

    PPerry57

    My advice, after these uprades and seen THEM fail miserably on the old PC (like yours) are NOT to do the upgrade.

    Sorry to be the bearer of bad news, but the problem, that you are facing is that Microsoft provides only pilots with the most basic features and what you really need for these features in laptops is the specialized drivers written for the specific material found in laptops - and unfortunately, there is no HP Win10 laptop driver.  HP only guarantees the compatibility of Win10 for machines manufactured after August 2013. HP is not no matter what timetable indicating when, or IF, they will produce drivers for older machines.

    This means that your PC is probably NEVER going to be fully functional under Win10 because the pilots is needs for all features simply do not exist!

    Also, there is no upgrade for the BIOS of your PC because it has not been compiled with Win10 in mind.

    While Microsoft tells you there is no risk in the upgrade of Win10, because they allow you to believe that you can always return to your BONES and the original installation program within 30 days, the ugly faction of the matter is that the Win10 GoBack feature turned out to be unreliable - and when it fails it can leave machinery in a State corrupted - that does not always happen , but it happens often enough to be a problem and you will get no warning beforehand that he goes to the trash your PC!

    Thus, people who tell you that you are no worse off the power if you upgrade to level do not take account of the reality of the situation - you'll be no better off and will be certainly less well off, how much, nobody knows.

    However, if you are willing to do some work and are determined to try to upgrade, then read on...

    You think about the amount of work that you want to post just to run Win10.  Seriously.  Old machine Win7 tend to come in two flavors when it comes to upgrading Win10 - really easy and really difficult.

    The really hard to upgrade computers fall into two categories: (1) those who are expandable to Win10 and works OK, (2) those who are not.

    Computers laptops HP, especially old Win7 machines, often came with two different graphics - and Intel chips and then either a processor AMD or Nvidia.  This was known as switchable graphics card or hybrid.  You have run using the Intel chip most of the time, but when you need additional graphics power, as in the game, the PC automatically switched over to the use of the AMD or Nvidia graphics chip.

    Problem is, this requires special graphics drivers to work, and while that those that are preinstalled on laptops Win7, these drivers simply do not exist for Win10.  These drivers are not available from Intel, AMD or Nvidia.  One way to tell if your PC has two different graphics chips is to look in under Graphics Device Manager.  If there are two different cards in the list, an Intel and AMD/Nividia, then you have this problem - and if you force an upgrade to Win10, you will have serious graphic problems and your machine will not work.

    However, if you do not have this problem, to CAN pass to Win10, but you must be willing to do four things:
    (1) do a full image backup of disk external drive or USB stick, capacity
    (2) changes to the reserved system partitioning hard disk recommandΘes mΘthodes,
    (3) use a different approach and maybe more than one, as Windows Update to do the upgrade,
    (4) prepare for a clean install.

    ---------------------------------
    1: backup of images:
    This is VITAL, because the machine is doomed to failure of the upgrade, and when that happens, you will learn that GoBack to Win10 function is NOT reliable, and that can leave you with a corrupt machine that will require the factory reset and lose all that on it, to get it working again.

    You can avoid this by making an image backup to an external hard drive or a USB drive using Macrium reflect (MR), which provides a FREE version that can be used to image and restore partitions or drives together.

    What I recommend is the following:
    (1) download and install Macrium reflect (MR)
    (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
    (3) use the option to create a CD or a USB startup key

    NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.
    ---------------------------------
    2: System reserved for resizing:
    There is a small partition on the HDD with Win7 preinstalled machines known as system reserved.  It is something known as the boot loader code.  There is 100 MB format: all that is necessary for Win7.  But Win10 needs 350 MB and, in some cases, is NOT able to resize it on its own.  IF this happens, you must manually use a partitioning tool to resize it yourself.
    ---------------------------------
    3: use a different approach to upgrade:
    Windows Update is the simpler, but less reliable, way to do the upgrade from Win10.  A much better and more reliable way is to use Microsoft Media creation tool: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10 choose the upgrade this option now PC.

    After all this, you know that MS install drivers with only the most basic features.  Given that HP does not have drivers for your PC Win10, this limited functionality is the best you're going to get.  HP does not actively write new drivers from Win10 for the old PC Win7.  To keep all the features of your PC, your best shot is NOT to upgrade to Win10.
    ---------------------------------
    4: be prepared to clean-install:
    If you do all this, and after the upgrade, your PC works partially, this means that the upgrade is not well and stuff is still there the previous OS corrupt the functionality of Win10.

    You MIGHT be able to solve the problem in fact a clean install of Win10. Problem is that, often, a clean-install does not recognize prior activation, even if it should. So, before doing the upgrade, follow these instructions on the community forums Win10 on creating a genuineticket.xml file: http://www.tenforums.com/tutorials/23354-clean-install-windows-10-directly-without-having-upgrade-first.html

    You need more later to activate your pc Win10 after the installation of clean.

  • Problem of PC keyboard laptop Compaq Presario CQ60-224NR after the upgrade from Vista to Windows 7

    I have recently upgraded the OS on my laptop PC Compaq Presario CQ60 224NR Vista Service Pack 2 to Windows 7 Home Premium 32 bit Service Pack 1.  I updated the drivers before upgrading and checked for the latest drivers after upgrade also.  After the upgrade, the keyboard of the laptop works only partially when I use a web browser.  This includes IE and Firefox.  Above the QWERTY keys do not work correctly.  If I press one of these keys or SHIFT and one of these keys, the last character, symbol, or space I typed before is repeated instead.  Y at - it a fix for this problem?

    Well, I searched for several hours and found a solution, at least for me I am a customer of Comcast and I installed constant guard.  There is a key logger that is included in the package that it causes the problem.  I uninstalled GuardedID and my problem disappeared.  I hope it works for you.
