How to understand startup mystery?

judgment of the iMac to 22:00 03:00 the next morning, I hear the chimes. 06:00 start and run terminal command "last" and it doesn't show anything between 22:00 and 06:00.
I need to make sure that this does not happen. I can turn off the ringer, but would rather understand why the mac has fired up this morning.
When I stopped the previous night, I think I was in bootcamp and changed the startup to El Capitan disk before stopping.
Thanks for any advice.

OS X El Capitan 10.11.5
End of 2012 iMac
Intel Core i7 3.4 GHz
32 g memory
NVIDIA GeForce GTX 680MX

Wake for network access has been checked in the settings.
Start after a power outage has not been verified.

Open Console.app and check the messages from the system log and Diagnostic reports.

    It can handle up to 16 GB memory DDR3-1333 (2 x 8 GB modules).

    No way to add a touchscreen. I don't know how you changed Intel Radeon graphics card, unless you have installed a different motherboard. The original motherboard has two graphics chips, so if you install the right driver you can access the AMD Radeon HD M 7470.

    The processor could theoretically be upgraded to an i7, but these improvements are rarely economically justified because of the high cost of processors unique and time required for doing the upgrade. Somehow, I think less than 10% of the improvements that we are discussing on this Forum actually. You simpler and better (more efficient) upgrade is to install an SSD. You will think that you have an i7 and 16 GB of RAM.

  • How to stop startup programs unnecessary popingup when I start my pc

    How to stop startup programs unnecessary upward poping when I start my pc

    How to stop startup programs unnecessary upward poping when I start my pc

    First of all, note that you should be in * all * the programs that start automatically, not only with those who are in the system tray. Not all the programs auto-start manifesting by an icon in the status bar.

    On each program, you don't want to automatically start, check its Options to see if she has the choice to not start (make sure that you actually choose to not run, not simply a "don't display the icon" option). Many can easily and better be arrested like that. If this does not work, run MSCONFIG from the start. Run the line and on the Startup tab, uncheck the programs that you do not want to automatically start.

    However, if I were you, I wouldn't do this just for the purpose of the minimum number of running programs. Despite what a lot of people tell you, you should be concerned, not with the way * a lot * of these programs you run, but * that *. Some of them can seriously affect the performance, but others have no effect on performance.

    Don't stop all programs to run willy-nilly. What you need to do is to determine what each program is that its value is for you and what the performance cost is running all the time. You can try searching the Internet and ask questions about the details here.

    Once you have this information, you can make a smart informed decision on what you want to keep and what you want to get rid of.

  • How to understand the time VI?

    Hello

    I use LV 8.6, and I'm curious to know how to understand statistics 'VI time' under the 'profile Performance and memory window.

    I let one of my screws "continuous run" for about 5 seconds, but in the profile window, time of VI out 1.17 seconds, while the SubVIs time is 0. If I understand well of the Help window, 'VI time' represents the time spent executing the code of the VI, what happens for the other 4 seconds? It is confusing to me because I did similar tests on other screws (with no subVIs), and it seems the faster of the VI, more time to VI is.

    Thank you very much.

    The time you see reported is the total of all the slices of the CPU used by the code.

    If the VI took 1 msec to start upward, then did a waiting for 1 second and then outputs, you should expect the total duration of about 1-5 ms alothough the run time in total was much more than that.

    Hi John McAvoy,.

    (1) since when are you facing this problem?

    (2) you get an error message?

    I want to clarify if this happens when you start Windows after logging in or before opening a session on windows.

    Method 1: Disconnect all external devices (printers, scanner, USB (universal serial bus) readers, etc...) Except the mouse and keyboard > restart the computer and check

    If this solves the problem, then add back devices at a time until you discover the piece of hardware causing the issue.  Then get any drivers\software update for the device.

    Thanks and greetings

  • How to understand how backup file is belong to what backupset.

    Hello

    I'm looking for an answer, but impossible to find for a while.

    for example, I backed up my system with this command:
    backup database section size 1G;
    and 4 file created for the backup (I guess that my database of approximately 4.5 G and global safeguard is 3. 5 g). There are 4 different files in a backup set after the backup command. I run this command again and 4 more files and second backup.

    Now, how I understand of RMAN or dynamic sql, views the backup files belong to what backupset.
    in 'Backup list' RMAN command does not display the backup sets (or I couldn't find something in common).

    also in sql, it has V$ BACKUP_SET and V$ element_sauvegarde views but I could not find relationship master detail between those points of view. in V$ Backup_Set view I can see the file and backup header information how that backup has to element_sauvegarde V$ RMAN_STATUS_RECID column has the same id for the same backup, but it does not exist in V$ Backup_Set

    in particular, I want to see this list in RMAN. is there a solution?

    Thanks for help.

    Hi Mustafa KALAYCI,

    This means Hmm so even if there is an ID that is unique about it, I couldn't see it.

    I'm afraid you're right.

    If I want to spend one of my old backup to a different location, how can I know which files I have to spend?

    You can use the handle and completion_time columns in v$ element_sauvegarde or the timestamp of the file OS to identify older files.
    (Be aware of old information from rman backup is purged of the controlfile due to pressure of space, check the control_file_record_keep_time setting)

    http://www.Stanford.edu/dept/ITSS/docs/Oracle/10G/server.101/b10755/initparams027.htm

    Not sure why you want to move the files, but if you do you must overlap.
    Kind regards

  • How to understand a dumpfile?

    Hello
    How to understand a trace dump file?

    I got the error ORA-04030. Then by applying the metalink note: 863562.1 I did:
    SQL> alter session set events '4030 trace name heapdump level 536870917;name errorstack level 3';  
    SQL> run reproducible sql 
    But I don't understand how trace file other than a SR on metalink to open?

    Thank you.

    You can't do if you do not belong to group support as they are trained to understand with the meanings explained correctly. These trace files are not supposed to be read by us and created, but they are supposed to be sent to the OSS, when we reached this kind of errors. You need to trigger an SR only if you want resolved as much traces contain memory dumps as well which are not possible to consider rightly so we do not know what we are looking for and what the error?

  • How to understand the reference trigger as a trigger to stop?

    Hello

    I tried to use an external signal how the trigger works / stop for analog data entry. I had looked for solutions and above all that they suggest to use a reference trigger. But I don't really understand how it is applied. For example, why it should be set to the number of samples before release? For me, the number of samples that are taken are those between the market trigger / stop... I don't really have it.

    Migne

    Hello master,

    As see you, there is no trigger stop easily available with DAQmx. Indeed, you will need to use the reference if you want to trigger the end of the acquisition. What actually a c of reference trigger on a task must begin a kind of continuous acquisition until the trigger occurs. Then by default you will get a certain number of samples before (before) and after (after release) edge relaxation when you read the buffer after the triggering event.

    To read data continuously during the acquisition, you must change a property to change the access mode during playback. You will also need to manage properly reading the buffer has you will certainly get the same amount of samples during the last reading.

  • How to remove startup programs to include information system?

    I have two questions:

    1. how to eliminate some startup programs - that is to say small icons that appear in the lower right of the screen after the home screen?

    2. What does the following error message, and how can I correct: «entry point procedure RegSetKeyValue is not found in the dynamic library of ink ADVAPTI32.dll»

    To answer #1 question, you can use the program 'msconfig' to Microsoft

    (Start-> Run-> "msconfig")

    to toggle the elements that run at startup... but especially for diagnostic purposes.

    A better way is to download the freeware from Microsoft "AutoRuns".  When you run it, it will show a list of items that run at startup and allow you to uncheck all that you desire.
