How to upgrade Compaq 620 Energy Star from non virtualization to virtualization support?

Dear HP community,
My Compaq 620 Energy Star notebook with CPU Pentium(R) Dual-Core CPU T4500, not support virtualization. For supporting virtualization, I want to upgrade it, e.g. upgrade motherboard (if necessary), upgrade BIOS, upgrade CPU etc. Please recommend the correct and compatible version/model of parts to be upgraded to enable virtualization in this notebook.
It is said it is not easy to upgrade the notebook, but I think with the correct tools and approaches, it shouldn't be difficult to upgrade the notebook.
Thank you very much for your help !

Hi,
Given all those plus labor cost. My suggestion: buy a new machine, a lot cheaper.

  • Is there still any hope to have virtualization feature for my compaq 620 energy star notebook?

    Dear HP Support,
    it looks like that the motherboard of my compaq 620 energy star notebook doesn't support virtualization technology, even though replace the processor with one with virtualization feature, my notebook still can't have virtualization feature. moreover it is said the CPU socket type of notebook is soldiered to the motherboard, so the processor of notebook can't be replaced. if this is the case, it seems that i can't replace the processor of my notebook.
    am i correct? is there still any hope to have virtualization feature for my compaq 620 energy star notebook?
    thanks,
    q.s.
    This question was solved.

    The processor can be upgraded; it is socketed. However, virtualization must be implemented in the motherboard and BIOS and without that, upgrading the processor will do no good. Which processor do you have?
    Here is the Service Manual:
    Manual
    See page 120....virtualization is possible on some models but I am going to assume only the models with a Core2 Duo processor. Celeron and Pentium Dual models use a different chipset on the motherboard so even if you put in a Virtualization capable CPU it would not work.

    Hi and Welcome to the Community!
    From your post, I cannot quite tell the specific process you are attempting...so I will give you everything...
    The simplest way is to, on a PC (you cannot do this on MAC):
    1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below.
    2) Uninstall, from your PC, any BB OS packages
    3) Make sure you have the BB Desktop Software already installed
    http://us.blackberry.com/software/desktop.html
    4) Download and install, to your PC, the BB OS package you desire:
    http://us.blackberry.com/support/downloads/download_sites.jsp
    It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.
    5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
    C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
    C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
    6) Disconnect your PC from the internet and turn off all radios on your BB (consider also removing the SIM...not likely necessary, but just in case)
    76a) For changing your installed BB OS level (upgrade or downgrade), you can launch the Desktop Software and connect your BB...the software should offer you the OS package you installed to your PC.
    7b) Or, for reloading your currently installed BB OS level as well as for changing it, bypass the Desktop Software and use LOADER.EXE directly, by proceeding to step 2 in this process:
    http://supportforums.blackberry.com/t5/BlackBerry-Device-Software/How-To-Reload-Your-Operating-Syste...
    Note that while written for "reload" and the Storm, it can be used to upgrade, downgrade, or reload any BB device model -- it all depends on the OS package you download and install to your PC.
    If, during the processes of 7a or 7b, your BB presents a "507" error, simply unplug the USB cord from the BB and re-insert it...don't do anything else...this should allow the install to continue.
    Good luck and let us know!

  • How to upgrade/downgrade an existing Arch from external media?

    Hi there!
    After last upgrade of kernel and video drivers i got a blank screen with no tty console.
    I read couple of threads in » Pacman & Package Upgrade Issues
    I found out that the solution would be "to boot from external media, chroot and downgrade kernel to 3.9.9"
    Questions:
    1.How would i do that?
    2.Should i downgrade or upgrade (if with  the new kernel the issue is fixed)?
    Thank you!

    https://wiki.archlinux.org/index.php/US … tion_Media
    https://wiki.archlinux.org/index.php/Chroot
    https://wiki.archlinux.org/index.php/Downgrade
    If the new kernel is fixed, that's the best answer by far. If it's not, downgrade until it is.

  • How to upgrade to OS X Leopard from OS X 10.4

    I want to upgrade my Mac from OS X 10.4 to OS X 10.5 Leopard, but I can't find a program to download to upgrade my Mac.
    Where can I find it?

    You posted in Intel iMac so I'll presume you have one.  You would probably be better off upgrading to Snow Leopard.  It will be cheaper and a lot easier finding the disc (buy it from Apple online).
    Get more information about your computer. Go to the Apple in the upper left corner of any window, then "About This Mac", then "More Info..."  Copy and paste the information here, but omit the serial number and Hardware UUID (if present).
    Compare with:
    Snow Leopard 10.6 Technical Requirements - http://support.apple.com/kb/SP575 - note by K Shaffer - http://discussions.apple.com/message/12921514 : "Some early Intel-based Macs can't use Snow Leopard 10.6 installers; of those, the Core Duo (not 2 duo) were suspect and had issues." - and a qualifier by "a brody" http://discussions.apple.com/message/13028822 : "I think that refers to the ones without at least 1 GB of RAM."
    Also consider:

  • How to upgrade Leopard to Snow Leopard for non-US customer ?

    Hello everyone, I have Mac Book Pro 5,1 with Leopard disc and I live in Latvia, made a clean install recently, and now I want to upgrade it to Snow Leopard. Here the fun begins.
    First I tried to order update disk from Apple Online Store, for US and GB there is no option to post it to another country.
    Then I checked all local Premium Resellers, they don's have a disc for sell and only response is Only through Apple App Store online
    But how I use App Store to upgrade my Leopard if it requires Snow Leopard.
    There is no support messages over Internet, nothing at all.
    I just want to legally buy Snow Leopard and then buy Lion, that's all. But instead I have headache and no way to buy it, because I in poor country without normal apple support.
    What I need to do to get os upgrade ?

    Hi Danpiel and welcome to Apple Discussions,
    Try on ebay. Click this link to ebay.co.uk
    http://www.ebay.co.uk/sch/Software-/18793/i.html?_nkw=snow+leopard&_catref=1&_tr ksid=p3286.c0.m1538

  • HT5248 how do I import an Appleworks document from Appleworks 6 PC power support is not supported

    I am unable to access some appleworks 6 documents saved onto a flash drive.  I was told pages would fix this and I downloaded the software.
    I don't know how to access the information, just clicking on the document on my flash drive still gives me the same error message "Appleworks PC power6 is not supported.

    Did you install Pages? Drag the word document from your flash drive onto your desktop. Then try double clicking it or launch Pages and choose "Open" in the file menu. Note: Pages can read word documents; Numbers can read spreadsheets, but nothing can read painting documents. If you still have access to a Snow Leopard installation, I'd open them there and then save them in another format.

  • How to determine if user is autheticated (from non-secured resource in web)

    Is it possible to determine if a user is autheticated from a non-secured servlet in a web application?
    I have a servlet served to both public and autheticated users. This servlet performs different logic depending the user whether is autheticated or not.
    The getRemoteUser() is useless due to the servlet is not protected (for public users).
    My application is set to use declarative security and form based logon.

    Please try it out...getRemoteUser is the answer..
    For example, Lets consider the following scenario.
    S1 -- secured servlet
    S2 -- public servlet
    (assuming form-login already happened)
    Req1 -- S1 -- dispatches to -- S2 (getRemoteUser returns the user authenticated)
    Req1 -- S2 (getRemoteUser returns null)

  • For virtualization, what processor can replace Pentium(R) Dual-Core CPU T4500 of Compaq 620?

    Dear HP community,
    I bought a Compaq 620 Energy Star notebook 3 years ago, and its processor is Pentium(R) Dual-Core CPU T4500, but without virtualization feature. For supporting virtualization etc features, can you recommend a suitable processor to replace it without replacing the other components, and the notebook still perform as well as before? Moreover, what tools are required to replace the processor?
    Thank you very much for your help !

    i did some research, it looks like that the compaq 620 energy star notebook can  be upgraded to have virtualization feature by only replace the CPU (support virtualization), without replaceing any other components, e.g. the motherboard. it is much appreciated if anyone can help to confirm this.
    moreover, it is said that it is not good to replace the component like CPU of a notebook, because some of the notebook components are soldered to the motherboard, but i'm thinking this doesn't mean the notebook components can't be replaced. with the right tools, the right apporaches and with caution, the notebook components, like the CPU, can be replaced. it is much appreciated if any one can help to confirm this as well.
    if only upgrade the CPU (with virtualization feature) which is supported by the current motherboard (compaq 620 energy star), can the whole notebook system support virtualization technology (including motherboard, BIOS, CPU etc)?
    please do help to answer the above questions, and give me the firmed advice on upgrading the whole system to enable virtualization feature. i don't have enough budget to purchase the new computer system, so perfer to upgrade.
    thank you very much for your help in deed !
