HP12C

On start-up, my HP12C screen shows 0,00 and a blinking "*" in the lower left hand corner, "Begin" in the middle, and "D.MY" in the lower right hand corner. How do I get rid of this and reset?

Hi,
The * is the low battery indicator. Replace the battery with new from a good make sourced from a reputable supplier.
To reset the calculator, switch OFF then hold down the "-" (minus key)  and press ON.  "pr error"  will appear, this indicates the calculator is reset. Press CLx to clear the display. BEGIN and D.MY should also be gone.

  • HP12C Displays 7.00 on start-up and post reset

    Hello: does anyone know how to get this calculator back to original settings?  I did the "On" while holding "-" to get the prerror message but the calculator still displays 7.00.  It seems like the display is messed up on the very left and bottom of the first digit. 
    any ideas or is it garbage after only 1 month ownership

    Hi,
    These errors are common with low batteries (the low battery indicator is unreliable).
    Try with new batteries from a reputable make and source.

  • Time Machine, Migration Assistant, and a BIG headache

    Set up my new rMBP from a time machine backup on external and worked great. I removed some applications from the dock that didn't transfer over successfully (i.e. Word 2004). I didn't include iTunes during the transfer.  Once time machine restore was complete, everything on the rMBP worked great.  I wanted to get my iTunes from the external and so I used the Migration Assistant to copy over JUST the music.  I unchecked all the boxes except Music.  Took over 1 hour just to copy over 30GB of music and so I was suspicious...
    After completion, I see that it copied over my music, BUT
         - all Documents gone
         - applications previously deleted WERE BACK (i.e. Word 2004)
    Went back to my old 2010 MBP to do another time machine backup, and signed into Mail....
    Signed into Mail on the rMBP....
    Got an email that my apple ID was used to sign into iCloud....
    Then now rMBP Mail can't access ANY of my email accounts....
    What in the world happened?  I just wanted to copy over my Music and now it's a BIG headache.....
    I knew I should have avoided Migration Assistant and should have transferred over Music upon initial setup of the rMBP....
    Tried to restore the rMBP from time machine but cannot b/c the time machine backup was done under snow leopard....
    So uninstalled Mavericks and reinstalling....1 hour wait to download...
    Then (hopefully) will restore from time machine (make sure to include Music this time)....which takes about 2 hours....
    So 3 hours just to get Music, when it should just be a simple copy/paste job....
    On the bright side, I got a Samsung display and so I'm happy with that...the display is sharp, evenly bright, and no creaking case

    Hey hp12c,
    Thanks for the question. The following article may provide the information you are looking for:
    Mac Basics: Time Machine

    Restoring specific files or folders
    Choose Enter Time Machine from the Time Machine menu and the restore interface appears. You can literally see your windows as they appeared "back in time."
    You can use the timeline on the right side of the window to reach a certain point back in time (the timeline shows the times of all backups on your backup drive). If you don’t know exactly when you deleted or changed a file, you can use the back arrow to let Time Machine automatically travel through time to show you when that folder last changed.
    Note: Dates in pink indicate the data resides on your Time Machine backup device. Dates in white indicate the data resides on your Mac. In OS X Mountain Lion and Lion, portable Macs have the feature of local snapshots. See this article for details.
    You can also perform a Spotlight search in the Time Machine Finder Window search field to find a file. Simply type the Spotlight search field and use the back arrow to have Time Machine search through your backups to find what you are looking for.
    Before you restore a file, you can also use Quick Look to preview a file to make sure its the one you want. Highlight the file and press the Space Bar to bring up a quick look.
    To restore, select the file/folder and click the "Restore" button. The file will automatically be copied to the desktop or appropriate folder.  If the file you are restoring has another file in the same location with the same name, you will be prompted to choose which file to keep or keep both.
    Thanks,

  • Time Machine, Migration Assistant, and copying specific files to a new machine

    Things were running fine. Then repeating kernel panics! A fresh Mountain Lion install seemed to fix things. To test whether the panics were related to some application or preference, how can I restore only my data, specifically the Aperture library, iTunes library, and iMovie library and nothing else from my Time Machine backup? In other words, how can I see the file structure of the Time Machine backup so I can copy only specific files and folders?
    Thanks for any advice!

  • HP 12C Display Problem

    I have two HP 12C calculators that are now missing bars in the display - so for example, an 8 will look like a 6 or an H. Both calculators are not very old and have not been damaged. Has anyone else faced this problem? Is there a solution?

    Please see my post in the following thread:

  • IOS Newsstand: Cannot install item please restart the app and download your purchase again.

    I'm struggling with iOS 8 Newsstand. I've downloaded the new issue of "Intelligent Life." The issue opens then crashes after one page turn. When I try to reopen the issue, I get an error message, "Cannot install item please restart the app and download your purchase again." I've deleted the app and reinstalled it but no change. I've tried to "Restore All Purchases" also to no avail. Advice?
    Other Newsstand titles work normally.
    Thank you.

    Hello hp12c,
    If you are still having crashing issues with the app, check against the article below to continue your troubleshooting. Check to see if magazine has been updated to be compatible with iOS 8. If you are still running into issues, you may need to contact the developer.
