I need to change to El Capitan in Yosemite ASAP...

Hi, I need to return to Yosemite after installation of El Capitan.

Need to do this right now to make my camera works again in Lightroom.

Thanks for any help that could solve my problem as soon as possible.

Make a backup, preferably 2 separated on 2 separate drives.

OS X El Capitan: revert to a previous version of OS X

If come back you, I would like to use Setup Wizard to restore your data. This process takes some time, so do it when you don't need the computer for several hours, based on my experience.

    In one of my firefox browser, the header/footer margin setup parameter is inches, I need to change it to milimeter to inches. Your help is appreciated.

    As far as I KNOW Firefox displays the metric or Imperial depending on the type of paper selected for printing. If you are using A4, you should get millimeters/metric.

  • I tried fixing to uninstall Firefox reinstall that did not work. I always get the same error message: Firefox has stopped working. May need to change!

    I'm not the only one having this problem why Mozilla does not do something? I'm fed up about & may need to change to another browser! Firefox is the best browser I've ever had, but not more! Here I could go back to the old version - it worked great! The new version is when I started having this disorder.
    Time for Mozilla to step up & get that a difficulty or you will lose more than me I think! I disabled real arcade & most of the other modules. That did not help either.

    It is possible that your security (firewall, antivirus) software blocks or limit Firefox or the process of plugin-container without you inform, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox and the plugin-container in the permissions list in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    I used the scan to email for a long time. My gmail account has recently had a change of password and I need to change it in my printer. There was once a scan to E-mail wiizard but since installing windows 10 he's not here. Does anyone know how to do this?

    Hello

    Tap on WiFi / Ethernet icon on the printer and locate its IP address.

    From your PC, open a browser and navigate to the IP address of the printer.

    Open the San tab and select the profiles of outgoing e-mail following scan to Email section.

    Click on change profile mandatory email and follow the steps on the screen while keeping the current settings and only change the password.

    Note: If you do not set a PIN code (a code 4 digits for the digitization of the printer), delete the contents of box PIN which may be filled wrongly by the browser when the steps on the screen.

    Once you are done press on save and test.

  • Need to change battery RTC in NB10-A-102

    Good evening everyone, I need to change the buffer battery RTC from my PC (is the clock battery, whenever I turn on my PC it at another time).
    I do not know how to disassemble the right and I don't want to break nothig.

    can someone link me any guide? or teach me how do I bought the PC a month before and I don't want to call and spend money in aid for a stupid battery (I know it is under warranty, but tshiba call is not free and I don't want to spend more time and money

    Thank you all.
    At latest

    I would not recommend you to disassemble the laptop and try to remove the RTC battery.
    First, this battery can be charged.
    The laptop must be connected to the power adapter and must be turned on for about 24 hours.

    During this time the main battery as well as the RTC (BIOS) battery is charged.

    Try it and forget the RTC battery replacement.

  • I need to change the keyboard on Tecra M5

    Hello

    I need to change the keyboard on a tecra m5.
    Unfortunately, this is not mentioned in the manual how to do this.

    Please advice.

    Thanks in advance for your help.

    Best regards
    Wim Gijsels

    Hello

    I think that it s not mentioned in the manual, because I should only be made of professional technicians for laptop

    In any case, a friend of exchanged me the keyboard and told me to remove the keyboard first support. Who s the plastic cover between the keyboard and LCD display. So open the LCD screen and use your fingers on both sides and lift the keyboard bracket. There are two screws that attach the keyboard under the door-keyboard. Remove the two and lift the keyboard. Last but not least remove the keyboard plate to remove the cable from the keyboard connector.

    As you can read it's not that complicated and I hope I could help a bit! :)

    Hello

    You will need a compatible CD/DVD player.
    Not all readers are supported due to different master/slave/c-salt settings.
    ODD, that uses wrong settings will not be recognized by the BIOS.

    You can buy a compatible player to a Toshiba ASP in your country.
    You can also consult your user manual.
    In my manual, I could find some information on the compatible sides
