    You can connect otherwise?  USB or FireWire or love at first sight?  You can connect both machines and start the one you want to transfer to target disk mode.  If your other machine is up and running with an account on it and you just want to move files, you can simply drag and drop the FRO the machine mounted TDM, or you can use the migration wizard.

    Or, if the other machine still starts and runs, you can start both computers and connect to the same wifi network and share the hard drive like machines on the network.  Access them in the finder on the new machine files and drag-and - drop, or use the wizard migration, on wifi.

  • ProBook 4320 s: how to reset the bios password

    Hi guys, I Don t know if this thread is in the right place, if not mods can move.

    I need to know how to reset the password of the bios for HP ProBook 4320 s.

    @Spaha

    I couldn't find one in the warehouse so I did not test this.

    Contact HP and they should be able to send you a file custom SMC.bin that you can use to reset the password at startup.

    http://welcome.HP.com/country/W1/en/contact_us.html

    When you talk to the HP rep ask them to increase your service request.

    Or download these files.

    Insert a clean USB flash drive.

    Then run USB Image tool.

    Choose the flash drive, and then click RESTORE.

    Remove the flash drive after the restore.

    Insert a locked in a portable flash drive and boot. "If the HARD drive is installed remove before start".

    First thing is to save your settings.

    Select 3 # re-program.

    Press "S" to save the system information.

    Type HPBR and press ENTER.

    Given that your model is not listed, select "SHOTGUN".

    After the reboot, repeat 'SHOTGUN' a second time.

    I would like to know the result, so I can update my list.

  • No Signal from my computer to the TV with an HDMI cable

    Hi, I have a Pavilion dv6 with operating system windows 7. the cable works with my friends on tv computer but not mine on television.

    Hi Zack1,

    Try this to see if it helps.  Download the Chipset driver and the graphics driver on the links below and save the installation on your desktop programs.

    Chipset

    Graphics driver

    Then, in Device Manager, open graphics cards, right-click on the graphic chip Intel and select Properties.  Click the driver tab, and then select uninstall.  Once completed, do the same for the for the Intel High Definition Audio Codec under his video and game controllers.

    Return to the desktop and install the driver from the Chipset, then the graphics driver.  When finished, restart the PC and see if that helped.  Check in that both Device Manager the Intel graphics card and Intel Hi Definition Audio codec have reinstalled successfully, and if you see now the Audio HDMI option under the playback (found in Control Panel, sounds) devices, as demonstrated by the top option on the screenshot below (ignore the fact that it is ATI ", I just said the TV icon option).

    If it appears correctly, try the HDMI connection and see if it works now correctly.

  • I got a call from people claiming that there was a problem with the computer.

    Original title: scammed by PCWizards?

    A few days ago I received a call from PC assistants saying they were Windows operating system support. They tell me that they have noticed that I had many requests from spam junk that was slowing down my computer. Unfortunately, as I had a big problem with my computer in time, I bit. I was very nervous about it at the time, but since I had so many problems with my computer and that you didn't know what to do, I fell prey to their plot. They talked to me in a 6 month contract for a fee of $99.00. After they have finished the maintenance on my computer, it worked very well, too gullible me thought: maybe they are legitimate.

    At the end of the interview I googled their business and came across an article that has been exposed as the crooks and claims that Wizards PC installs a spyware sophisticated by giving them access to the victim's computer remotely.

    To reassure myself, I decided to call using my Norton Security System. Their technician checked my computer and found a few things that their technology did not that he should have done; such that no detected restore points, the registry was not cleaned (35 detected registry errors) and it did not remove some software malware browers (toolbars).

    On his recommendation, I recalled PC assistants. The first tech I talked didn't seem to know what he was doing, so I hung up with him and sent their support line and ask them to address these problems or I would withdraw the payment from my credit card. Almost immediately after sending the e-mail, another technician called me. Unknowingly, I had all ready filed a dispute with my credit card company. I intend to cancel the service, but I am still concerned by some spyware detected on my computer. What is the best way for me to handle this? How can I get authenic proof that I was definitely scammed and I should report it to the Internet Crime Center? Using my computer for a few basic daily functions, must not be so stressful!  Any constructive guidance would be greatly appreciated!

    Hello

    It's a scam.

    Either these so-called "Microsoft" Tech companies want to sell you a worthless software, or remote access to your computer to try to steal your credit card and bank information and also achieve an identity theft on you.

    You gave them remote access and if you do Internet banking, contact your bank, explain, and change passwords.

    If you use your online credit card, cancel and get a new one issued to you.

    And the only way that willl you know that you are free to them is to backup your data and do a clean install of your operating system.

    The first thing I would say (if you have not already done) is to ensure that you have the latest version of Shockwave installed.  If you have still a problem, I would like to run IE without Add-ons and then put only the module Shockwave Player and the test.  Also, follow the other steps listed here and post back with the results.

  • Windows 7 - how the hdmi cable from the pc to the tv

    Original title: need help

    How does the cable from the PC to the tv hdmi

    Hi paulgibsonTF,

    The problem is that Windows developers are (I think) try to be too smart - if your computer doesn't have any HDMI cable plugged into it, and you do not have a HDMI device at the other end of the cable (like a TV or surround sound amplifier / speaker system), then Windows will simply ignore the Windows software for the HDMI driver is loaded.

    And even when you have a device HDMI plugged in and turned on, sometimes, Windows does not see that it is there. So don't mind allowing you to set the parameters of the device.

    Now... to begin the search. Go down on the status bar (this bar on the lower edge of the screen) system and find the sound icon - looks like a small speaker. Click on it and click playback devices. On my computer, I get a window ACOUSTICS, and it only shows a device (speakers / headphones).

    I don't have a connected HDMI device this time. But I do not have the device drivers loaded.

    Recently, I tried to plug in this same laptop to my TV HDMI, and... of course, Windows won't see HDMI devices are there and it is plugged. Once again.
    WHY? I do not know. But I had to pass by there is two years (even mobile) was about four cycles to uninstall the device HDMI driver, reinstall it, turn off things, disconnect, turn them, plug them,... and all of a sudden it started working.

    If Microsoft is still looking at this forum and answers other than "Windows 8", I'd love to hear them also!

    For example, I have a file of newspaper advertising open (as in Illustrator) .ai and I want to use the logo from here and place it in a .psd file (banner that I do in Photoshop). Before that I selected just Illustrator logo/layer and drag droped to Photoshop. This logo would be recognized as a smart object in Photoshop. Now, this is not possible. I'm working on Windows 10 x 64 and this problem occurred with the last update of Photoshop.

  • I'm trying to transfer data from hard disk of Vista again Windows 7 with the StarTech easy transfer cable. Is not interesting! Help please?

    My Dell laptop is quite old and SLOW but effective. I bought a new Toshiba Windows 7 laptop, and they had ideally made available a kit to transfer all the data from the old computer again. For windows USB transfer cable. Well, I loaded the CD and he always tells me that the compputers cannot read each other, to load the CD on my old computer. I'm on the flat. Called their tech support was a joke. Thought it would be so simple and now I want my $30 money back and may need to use the thumb or the CD burning command to transfer files.

    Anyone out there use this easy transfer cable and be successful?

    Many thanks to whom can help forever (or the cable my be used for some are completely other purpose if are getting my drift).  Thank you all!

    Hello

    Perhaps you use a defective cable, and also a standard USB cable cannot be used to transfer files and settings between computers.

    I suggest you to make Windows easy transfer on a network.

  • Smartphones from blackBerry Storm 2 (9550) synchronization of Contact with the Desktop Version 5.0.1.18 and Outlook 2003

    I just took my Blackberry last week and now in train to synchronize my contacts and have problems. I put the desktop software to replace the device to Outlook. That's why destroy all contacts on the device.

    All my contacts are sorted the name, first name. By examining the details of the synchronization (before it actually applies), I see that all the contacts on the camera original should be deleted (it's good!). But I find that some of the contacts are ignored and will not be added. In addition, some family names are now given names, and vice versa. When I have a John & Cathy'sname and a surname of Jones (for example), John is added as the first name, & is added in the middle and Jones is added under the family name. Nothing after the & is ignored.

    Is there a solution to this problem of synchronization? Are there better synchronisation software out there?

    Thank you

    Dwyne

    In talking with the Blackberry expert at the local Verizon store, I find the problem and the solution in the following way:

    Using the example "John and Cathy Jones '... The sync software looks at the name of Outlook in the format of "first-name vacuum vacuum-name last-name '. So when white was found during the synchronization, it assumes the & is the name of way and he picks up the last characters to the family name. I had to fix all my names "JohnCathy Jones" or "John & Cathy Jones". Two of these formats properly synchronized. However, the synchronization software does not care what is in the field of 'Society' Outlook, all characters are synchronized.

    Problem solved.
