  • Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ?

    Hello, I'm pretty sure my fan on my 2009 mac book pro has stopped running. Would this cause the computer to slow down and take for ever to boot up and show the color wheel every time I select an application ? how involved to replace fan ? cost ?
    thanks

    Not directly, but if the CPU overheats because of incompatible software, that would cause slowdowns. Do not allow the computer to run if the fan is not working unless you wish to fry your motherboard. Please make a Genius Appointment and take it in for service.

  • Ever since I installed MAVERICK, nothing now works, Flash Player won't run, printer works but scanner will not and the computer runs so slow.  Any help anywhere?

    wqn02h, first thing I would do is use Disk utility to repair permissions. Once this is done. Make sure you have the latest versions of the software you use. Also, check the manufacter of your printer/scanner for updated software. If they don't have updated software there are 3rd party alternatives that will work.

  • What's the go with this latest update. Half my apps don't work and the iPad runs slower? How do I go back to the old operating system?

    What's the go with this latest update. Half my apps don't work and the iPad runs slower? How do I go back to the old operating system?

    Make sure your apps are updated.  You might try Settings > iTunes & App Store > Automatic Downloads - Updates = "On".
    You cannot go back to an old operating system.

  • How to force the display to sleep, while keeping the computer running?

    I'm running some compression and transcoding programs on my iMac G5 (iSight) that keeps the CPU at 100% for hours at a time. My Energy Saver prefernces is set to sleep the display after a few minutes, but never to sleep the computer or the hard disk.
    Like I'd expect with such a high CPU load, my computer's screen does not go to sleep.
    Is there a program or command line utility that I can run to force my screen to go to sleep, but keep the computer running?
    iMac G5 17" (iSight)   Mac OS X (10.4.5)  

    To put your display only to sleep;
    Go to System Preferences, click on 'energy saver', check the 'Put the display to sleep when the computer is inactive for' box, and then set the time. Note; this just puts the display to sleep, not the whole computer. Your hard disk will keep running. I find this much more convienent than putting the computer in 'full sheep'. It wakes up much quicker without some of the hassle some computers display coming up from full sleep.

    Hi
    You check in SM50 by executing the programing, You will come to know which select is taking more time and accordingly you modify that select.
    You can do SQL trace and Run time analysis and analyse and see.
    check this and use
    1) Dont use nested select statements
    2) If possible use for all entries in addition
    3) In the where addition make sure you give all the primary key
    4) Use Index for the selection criteria.
    5) You can also use inner joins
    6) You can try to put the data from the first select statement into an Itab and then in order to select the data from the second table use for all entries in.
    7) Use the runtime analysis SE30 and SQL Trace (ST05) to identify the performance and also to identify where the load is heavy, so that you can change the code accordingly
    https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/5d0db4c9-0e01-0010-b68f-9b1408d5f234
    ABAP performance depends upon various factors and in devicded in three parts:
    1. Database
    2. ABAP
    3. System
    Run Any program using SE30 (performance analys) to improve performance refer to tips and trics section of SE30, Always remember that ABAP perfirmance is improved when there is least load on Database.
    u can get an interactive grap in SE30 regarding this with a file.
    also if u find runtime of parts of codes then use :
    Switch on RTA Dynamically within ABAP Code
    *To turn runtim analysis on within ABAP code insert the following code
    SET RUN TIME ANALYZER ON.
    *To turn runtim analysis off within ABAP code insert the following code
    SET RUN TIME ANALYZER OFF.
    Always check the driver internal tables is not empty, while using FOR ALL ENTRIES
    Avoid for all entries in JOINS
    Try to avoid joins and use FOR ALL ENTRIES.
    Try to restrict the joins to 1 level only ie only for tables
    Avoid using Select *.
    Avoid having multiple Selects from the same table in the same object.
    Try to minimize the number of variables to save memory.
    The sequence of fields in 'where clause' must be as per primary/secondary index ( if any)
    Avoid creation of index as far as possible
    Avoid operators like <>, > , < & like % in where clause conditions
    Avoid select/select single statements in loops.
    Try to use 'binary search' in READ internal table. Ensure table is sorted before using BINARY SEARCH.
    Avoid using aggregate functions (SUM, MAX etc) in selects ( GROUP BY , HAVING,)
    Avoid using ORDER BY in selects
    Avoid Nested Selects
    Avoid Nested Loops of Internal Tables
    Try to use FIELD SYMBOLS.
    Try to avoid into Corresponding Fields of
    Avoid using Select Distinct, Use DELETE ADJACENT

    Our application is a write intense application, maybe will write 2M/second data to the database, how to improve the performance of the database? We mainly write to 5 tables of the database.
    Currently, the database get no response and the CPU is 100% used.
    How to tuning this? thanks in advance.

    Your post says more by what is not provided than by what is provided. The following is the minimum list of information needed to even begin to help you.
    1. What hardware (server, CPU, RAM, and NIC and HBA cards if any pointing to storage).
    2. Storage solution (DAS, iSCSCI, SAN, NAS). Provide manufacturer and model.
    3. If RAID which implementation of RAID and on how many disks.
    4. If NAS or SAN how is the read-write cache configured.

    Hi Jon,
    Dreamweaver the following errors show up in the JavaScript.Log. I deleted the .dat file but no difference. I am not so confident in how to delete the preference file. I have been following the instructions (see link)
    https://helpx.adobe.com/dreamweaver/kb/restore-preferences-dreamweaver-cs6-cc.html
    Windows:
    ~Users\[user name]\AppData\Roaming\Adobe\Dreamweaver CC 2014.1 (folder)
    \HKEY_CURRENT_USER\Software\Adobe\Dreamweaver CC 2014.1 (registry entry)
    When Dreamweaver launches, it creates new preferences files and folder.
    How do I get rid of these errors?

    Try renaming the configuration folder that holds the .dat file first, before attempting to restore preferences.
    Many times that will take care of it without having to do all the work required after a pref-reset.

  • Computer runs slow after installation

    Hi,
    A little over a month ago I installed Tiger (using CDs) onto my iBook 10.1.5 OSX, 256MB, Power PC G3. A couple of times the computer ran slow at the start up but I would just re-start the computer and then it ran fine. This morning I turned it on I can't get it to stop running slow. Start up takes forever and any application I open takes a long time to start and runs slow after. What can I do to fix this?
    Thank you,
    Melissa

    You have adequate free hard drive space but keep an eye on it.
    But I do use quite a bit of memory on my itunes, about 5GB.
    How did you determine this?
    If you read the link I provided carefully, OS X makes automatic/dynamic use of Paging or Virtual Memory regardless the amount of RAM installed which uses available free hard drive space when utilized. This is released when logging out of your account and after a shutdown and/or a restart.
    The less RAM you have installed, the more Paging or Virtual Memory will be used depending on the number of running applications at a time and what each application is performing. This can make the system feel and operate more slowly.
    Check Resolving Disk, Permission, and Cache Corruption for system troubleshooting procedures and when doing so, follow all steps/instructions in the order provided.

  • Computer runs slow when Mac Mail open

    Mail works ok, albeit very slow, but the computer runs painfully slow.  Spinning beach ball trying to perform the most mundane tasks, like clicking between pages in Safari.  Once I right click on Mail and close it, the computer runs just fine.

    Also, with Activity Monitor open but Mail quit, select CPU down at the bottom, see what the % Idle is. Then open Mail and see what it says.
    You should run the Combo Update to 10.5.8. This might help.
    http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
    @Eric: I'm not ruling it out 100% as a fix for this problem, but Permissions Repair is not the panacea or valuable troubleshooting step you seem to think it is. It may have been more useful in pre-Leopard OSs like Tiger.

    Back up all data immediately as your boot drive may be failing.
    If you have more than one user account, these instructions must be carried out as an administrator.
    Triple-click anywhere in the line below on this page to select it:
    syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|Previous Sh' | tail | open -ef
    Copy the selected text to the Clipboard (command-C).
    Launch the Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V).
    The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
    A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that.
