HP Compaq CQ45-902TU with Windows 8 to be downgraded to Windows 7 Home Premium

Hi all

I bought a computer laptop cheap recently "HP Compaq CQ45-902TU with Windows 8" unfortunately cannot use it due to Windows 8' hostile user interface. I was intending to downgrade it. When I read the comments, they say I need to download drivers windows 7 first of this model CQ45-902TU HP Web site. HP site says that they do not provide it. What should I do? Is there anyone there to help?

Thank you

Sarah Lloyd

Hi, Sarah:

HP does not support PC consumers for all windows OS, but W8 64-bit systems.

Do your series of W8 recovery discs before install us W7, as most likely the recovery partition no longer works.

You must change a setting in the BIOS so that the laptop can boot from the installation of W7 media and for W7 run on your laptop.

See the link below for more information.

http://support.HP.com/us-en/document/c03736054

You will need to find a model with a similar material as yours which has w7 64-bit drivers.

I think that all the drivers and the software of this model should also work on your own, except the audio.

You must install the Intel graphics driver for your model.

DO NOT USE ANY BIOS OR FIRMWARE FROM THIS LINK FILES

http://h10025.www1.HP.com/ewfrf/wc/softwareCategory?OS=4063&LC=en&cc=us&DLC=en&sw_lang=&product=5278311

You can get the Realtek audio driver from the link below.

Accept the agreement. Download and install the second on the list (W7 64-bit).

    Hello

    First excuse my bad English, I'm french.

    A month ago, I bought an X 500 - 10W.

    I would like to re - install two old games that turned on my satellite M30-104 with windows Xp.

    I just can not install those on the Qosmio that works with Windows 7 Home Premium 64-bit, even if I use the compatibility mode.

    Is there a way to make these ancient works of software?

    I found the virtual computer (for windows Xp mode), but it only works with Windows 7 Pro or Ultimate.

    Thanks for your replies.

    This with virtual PC is good idea and you should get the right version.
    I mean if you have games that are designed for Windows XP Home edition, then you know that this will not work on the new operating system to Win7.

    original title: lack of games
    I have an Acer Aspire PC. It came loaded with Windows Vista Home Premium. Recently, I reformatted the hard drive and did a clean installation of Windows 7 Professional.

    I have no games. No solitaire, Minesweeper, no nothing.
    How can I, without seeking to erase and reinstall again?

    To activate the built-in Windows 7 games:

    1. click on Start (lower-left) and then on Control Panel.

    2. click on programs and features.

    3. on the left side of the screen, click on 'Windows turn features on or off".

    4. find the entry called games & check the box next to it.

    5. click on OK.

    6 reset.

    If the games box is already checked, uncheck the box , click OK, restart, then do steps 1-6 above.

  • H9-1150 Pavilion: H9-1150 PC does not start with WIndows 7 Home Premium 64-bit with ASUS 960 GTX card.

    I've seen others have posted simular questions, but I thought id repost this even in the case where there is more help.  I have the Elite Phönix Pavalion h9-1150 desktop with Windows 7 Home premium 64-bit.  and the bios HP 7.07 (seems no possible to upgrade the bios).

    As others have had I install the new graphics card, the 960 Asus GTX card that came out last month and the system start gives about 3 beeps in about 30 seconds and then it goes to a screen that is black with a blinking cursor and nothing else happens. cannot enter bios or settings for HP...

    I tried to disable UEFI boot devices in bios settings and enable only the legacy devices (after him swinging back on my original card, then move on to the new card), but it still gives 3 beeps after the start.   However, I was able to get into windows. Although I think that this may be due to turn off the computer with the old card in without power first. and after 3 beeps (which always blocks you on the bios menu) sometimes it appears the window where you can select the safe mode or normal mode... as sometimes happens if you start your computer with windows 7 If you had just it off without turning off power or something.  There, I can get into windows and run the PC and graphics card without problem, it's just when I try to start the problem happens.

    and suppor HP no. is NOT a fault of the card itself. As much before. I bought an EVGA card earlier a GTX 780 and SAME problem happened (although I have not tried to remove it then devices boot UEFI)...

    There is a problem of spacific with HP computers that seem to lock 'new' start-up equipment.

    Honestly not be blunted. I really think it's bad what I read somewhere that even if HP would never say it they do it on purpose to prevent people ruin of guarantee or any "liabity' that occur by people any other hardware on HP computers inventory installation

    makes no since to me.  the PC SHOULD be able to run the card. in fact his race he now once I was able to circumvent the blocking (temporarily) check markers, everyhting is fine tracks of card 3 times faster then old (that should be the case).

    But it's just this block as HP for some reason any installed on their bios/cards mothers is the question.

    Good news is I got it from amazon and I have about a month, until I return. which I think this time I'll make.  to see if something pops up in a month or something.

    It's the ONLY solution, it seems that HP has officially to deactivate start secure Windows 8

    but this isn't a computer of windows 8. and I guess even if install windows 8. the issue wouldn't disappear because given that its an older bios, there is no way to have a secure boot option to delete?

    HP you really need to get on the ball and give us a straight answer on this subject.  Is it ALL WAY to solve this problem? Can you not just do an older BIOS update to allow this? Or do you simply not want to worry about old PCs?

    anyway I think that it is wrong and very frustrating and to be honest. If this is the case when my pc otherwise MUST run on demand

    It's a PCI express 16 x slot card that is 3.0

    Here are the specifications of deetailed according to the guidelines of your page

    http://h20564.www2.HP.com/hpsc/doc/public/display?docid=c03273835

    the card SHOULD WORK fine.  I thought the GTX 780 was a little too much for the PC as he had more then a six pin port and needed a little more power, so at first I thought it was the question. so I returned it. and has now got this new card.

    However, the ASUS GTX 960 map requires the SAME power that the card GTX 550 it by default and the SAME SIX connector

    so it SHOULD work.

    and performance tests indicate that it FACT it's just stupid... bios that asks the question.

    I'm afraid to turn off the computer at the moment and try again to see if windows starts normally after you turn off the startup UEPI devvices because he cannot start properly...

    HP you are one of the largest suppliers of computers you know technology what are YOUR computers.  WHY cant you give us a direct awnser on this.

    ITS VERY frustrating

    and to be honest if I can't solve this problem, I am very hestient never buy another product HP if their spacifically computers have this new method of hardware locking.

    because I have the card now works on my pc, it runs great! 3 times as fast as it should! and yet, I know in the back of my mind, if I can't understand this bad likely issue just to send it back... less I have time.

    and for now, I did not have money to buy a new pc. This PC is JUST perfect for what I need for now another card then you want a little better...

    He shoudnt be as much hassle there?

    Thank you.

    Hello

    You need update the BIOS that is listed under Windows 8 to support the new graphics.   You must upgrade to Windows 8 or temporarily install Windows 8, you can install the update to the BIOS.  While there may be other ways to install the BIOS update, clearly having Windows 8 running will be the safest way.  8 BIOS version is your best chance to get the latest graphics cards to work.

    You can Windows 8 Enterprise 90 days trial.

    If you decide to install W8, then create external recovery HP Media and backup your data before doing anything.

    The reality is that there is no guarantee that any particular graphics card will work in any particular PC, even if the graphics card works in other PC or even the same or similar model PCs. Know what the return policy is before you buy.

    Power outages often lead to problems of material with computers / laptops.

    If there's nothing on the start screen (HP Logo, etc.) at startup, you may have a hardware problem.

    If under warranty contact HP.

    If this isn't the case, under services, contact a repair shop, local.

    Hello

    The following article should be useful. To use system recovery options, you have Vista installation disc. OEM (Original Equipment Manufacturer) repeatedly will install on the computer Windows recovery environment. To cross check if it is installed, try the following steps.

    1 start the computer and press the F8 key continuously to get advanced boot menu options.
    2. on the menu advanced startup options, check if the Startup Repair tool is in the list.
    3. If so, select it and press ENTER.
    4. If not, then you should organize a Vista installation disc.

  • HP dm4-3099se with Windows 7 Home Premium format and would like to re - install Home Premium

    My laptop is HP Pavilion dm4-3099se and it came with Windows 7 Home Premium. The password was lost and I was advised to format the system. The system has been formatted (all disks have been removed except for drive C :) and an OS from Windows 8 pro installed. Shortly after the formatting, found the lost password. If possible, I'd like to go back to the operating system supplied with the system (i.e. window Home Premium) and also get all the drivers provided with the system.

    Please, help me.

    Hello

    There are two options available.

    1. you can order a set of replacement recovery disks using the link below - it will reinstall the operating system, all the drivers, and almost all of the original software (the exception being often tests of MS Office).  They will also recreate all of the original scores, including the recovery Partition.

    Order HP recovery disks.

    2 another option that you might consider is to create your own Windows 7 installation disc.

    Also, if possible, back up the folder swsetup which lie at the root of the C drive.

    You can create a Windows 7 installation disc yourself using another PC - just download the good Disk Image ( this must be the same version that originally came with your laptop - it is listed as Windows 7 Home Premium 64 - bit ) from the link below and use an app like ImgBurn to burn the ISO correctly on a blank DVD - a guide on the use of ImgBurn to write an ISO on a disc is here.  These Images are clean and a very respected source (Digital River).

    Windows 7 sp1-iso-official-32-bit-and-64-bit

    Use the disk to perform the installation, enter the activation key of Windows on the label of the COA at the request and once the installation is complete, use ' 'phone Method' described in detail in the link below to activate the operating system -this made method supported by Microsoft and is popular with people who want to just have a new installation of Windows 7 without additional software load normally comes with OEM installations.

    http://www.kodyaz.com/articles/how-to-activate-Windows-7-by-phone.aspx

    Regarding the drivers etc, you must, if you were able to save the swsetup this will contain all the software installers and drivers for your laptop - if you were not able, drivers and software, you may need can be found here.

    Hi Sunday47,

    There are many causes of Code 39 errors:

    ·         A required device driver is missing.

    ·         A required binary file is corrupted.

    ·         There is a problem with the file I/O process.

    ·         A driver that refers to an entry point in another binary file cannot load.

    I suggest you try the following steps:

    Step 1: Run the fixit available in the link below

     

    Your CD or DVD drive is missing or is not recognized by Windows or other programs

    http://support.Microsoft.com/kb/314060

    If the problem persists,


    Step 2: Uninstall and reinstall the drivers.

     

    1. click on start and then click Control Panel.

    2. click on system and Maintenance, click System, and then click Device Manager.

    Note If Control Panel is in Classic view, double-click System and then click on Device Manager.

    3. If you are prompted for an administrator password or a confirmation, type the password, or click on allow.

    4. in Device Manager, expand CD-ROM/DVD-ROM drives, right click on the device CD and DVD and then click on uninstall.

    5. When you are prompted to confirm that you want to remove the device, click OK.

    6. restart the computer.

    After the computer restarts, the drivers will be installed automatically.
