  • How do you reset SMC on MacBook Pro

    How do you reset the SMC on a MacBook Pro? I am trying to get rid of that intolerable fan noise and was told this may help.

    I have had problems with a usb device from SONY, and after talking to AppleCare - I reset the SMC - and then the usb device mounted again. But, when I logged in as the normal user - the device did not mount again. Strange. Is there a difference when it comes to user levels?

    I did not get any idea about local server.
    Please Can you write it in detail?Is your host server Windows or *nix?
    for *nix, on the host server, and logged on as the owner of the oracle software (probably 'oracle')
    export ORACLE_SID=nameofyoursid
    sqlplus / as sysdbafor windows, replace "export ORACLE_SID" with "set ORACLE_SID"
    And I suggest you spend some time in the 2-Day DBA Manual, just for beginners.
    Learning how to look things up in the documentation is time well spent investing in your career. To that end, you should drop everything else you are doing and do the following:
    Go to tahiti.oracle.com.
    Drill down to your product and version.
    <b><i><u>BOOKMARK THIS LOCATION</u></i></b>
    Spend a few minutes just getting familiar with what is available here. Take special note of the "books" and "search" tabs. Under the "books" tab you will find the complete documentation library.
    Spend a few minutes just getting familiar with what kind of documentation is available there by simply browsing the titles under the "Books" tab.
    Open the Reference Manual and spend a few minutes looking through the table of contents to get familiar with what kind of information is available there.
    Do the same with the SQL Reference Manual.
    Do the same with the Utilities manual.
    You don't have to read the above in depth. They are reference manuals. Just get familiar with what is there to be referenced. Ninety percent of the questions asked on this forum can be answered in less than 5 minutes by simply searching one of the above manuals.
    Then set yourself a plan to dig deeper.
    - Read a chapter a day from the Concepts Manual.
    - Take a look in your alert log. One of the first things listed at startup is the initialization parms with non-default values. Read up on each one of them in the Reference Manual.
    - Take a look at your listener.ora, tnsnames.ora, and sqlnet.ora files. Go to the Network Administrators manual and read up on everything you see in those files.
    - When you have finished reading the Concepts Manual, do it again.
    Give a man a fish and he eats for a day. Teach a man to fish and he eats for a lifetime.

  • S750 - How many people get the power on/off/resetting issue?

    How many people get the power on/off/resetting issue?
    I've had my S750s for about 6 months, with X-Fi Elite Pro, and has been doing it since.
    Any idea on what's the cause? Something to do with the control pod?
    Thanks.

    Hi,
    What do you mean exactly? On my side I have power on/off/resetting issue when the speaker are in standby mode (thus red light on the control pod) and when I switch them on via the remote control or the control pod. It makes a strange noise in the subwoofer ("clic"), the red light disappear, then a new noise and the speakers are switched on. The problem is that all volume levels (rear / side / center / sub and main) are reinitialized! I have to configure them each time this problem appears...
    I have a Creative Sound Blaster Audigy 2 ZS connected to this speaker system. For me it is related to an electrical problem in the subwoofer like if the voltage was not stable (variations).
    Regards,
    Vincent

  • All my programs are opening in adobe even the system restore and the regisrty - how do I reset all programs to their originall default programs. Please help

    all my programs are opening in adobe even the system restore and the regisrty -
    how do I reset all programs to their originall default programs.
    Please help.
    PS I have also tried starting in save mode and still have the same problem.

    Hi,
    As
    BurrWalnut mentioned, first please run a virus scan to eliminate virus infection (if AV program is not opened in adobe)
    The files association could be corrupted in your situation, apart from the solution posted in the first reply, I also suggest you check Control Panel\All Control Panel Items\Default Programs\Set your Default Programs or Associate a file type or protocol
    with a progra,, manually check the association and check if it can do some help.
    Add: another way to open restore point is launching it in recovery console, please refer to this guide

  • Someone changed my passcode! How do I reset my phone without a power cord or iTunes?

    Well earlier this week, my iPhone 5c was stolen. but I got it back from the school's office. I had a passcode sent on it before so i simply entered that passcode into the phone but it wouldn't let me in at all. Now i guess you can say that the person who took my phone bypassed the passcode and changed it. I was wondering how do you reset the phone without a power cord or iTunes?

    Unfortunately, you can't.  You will need to access the computer you sync with and use iTunes.  This link will provide help:
