Can you give us more details what's happening?

You use external speakers or audio devices?

Y does it, and if so, what devices are used with the computer other than the keyboard and mouse?

Have you tried to disconnect and connection instead of a reboot?

What preferences-> audio-> see the output after waking up from his sleep?

    My PS6520 wireless printer will not print when she goes to sleep, any idea? Thank you

    Hi 464544,

    Welcome to the Forums of HP Support! I understand once that your HP Photosmart 6520 starts in mode "sleep" you cannot send a print job, it does not automatically standby upward.

    Please take a look here:

    The printer into standby mode after five minutes of inactivity to help reduce energy consumption. The sleep time can be changed from the control panel. The printer will wake up mode 'sleep' to print when a print job is sent to it.

    However, the auto power off feature must be disabled. Auto Power-Off turns off the printer completely, you must use the power button to turn the printer back on. You can change the setting Auto Power-Off from the control panel. configuration -Source

    Menu Configuration > other Menus > Eco > auto shut-off > off

    I hope this helps.

    WiFi connections are losing their strength increases the distance between the router and so as a general rule, there are some conflicting objects

    Try the following steps please

    The following actions and after each test to see if the issue is resolved - if yes, then you can omit the following steps - I tried to list them in ascending order of the effort at least on a Mac and / or an iDevice

    1. Check if the problem is related to a single device and if other devices connect normally-
    2. If the answer 1 is 'yes' - try to connect the device assigned to somewhere else if possible - coffee or the University
    3. Perform a forced - restart cela do not delete or purge all data and allows to solve many problems - here is how - press and hold the Off / On Home button and at the same time for about 15-20 seconds, until the Apple logo appears. Allow normal startup upward.
    4. Settings - WiFi - < network name > - Click on forget network - do a restart forced according to 3 and then add again the network
    5. If home - reboot the router by unplugging it for 60 seconds (power) and the plug and reconnect - obviously, this step can be done in a public place like a cafe or airport or University. While you're there - make sure your router is working on the latest firmware (check manufacturer's website)
    6. Settings - general - reset - Reset network settings - remember to have very practical WiFi passwords because it erases the WiFi passwords
    7. If it is a new specific net device in your home - make sure that the router gives enough DNS for all numbers which must / wants a connection - stuff like the printer, Chromecast get overlooked - ask for more details on this so not sure option
    8. Backup the device to iTunes - restore as NEW (no) - see if solves problem - if yes - restore backup
    9. An appointment of 'Genius' to an Apple Store, or select another authorized service provider.

  • How in the world does Mac loses its universal as shortcuts CmdC (copy)?

    How in the world does Mac loses its universal as shortcuts CmdC (copy)?

    Lost the feature universal paste. Manually add them back in keyboard shortcuts. They do not work in all programs. If I copy and paste a url in a browser, it is not paste in ANYTHING. What an absolutely frustrating experience! The most common features have disappeared and now they don't work well. Really? Come on Apple! This is not what Mac users are accustomed to Apple.

    Run disk utility to see if the startup disk needs repair.

    You can also try a Safe Mode boot that removes the system caches that can help...

    Follow these steps to start in safe mode.

    1. Start or restart your Mac.
    2. As soon as you hear the startup tone, hold down the SHIFT key.
    3. Release the SHIFT key when you see the logo Apple appears on the screen.

    After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

    To leave safe mode, restart your computer without pressing any keys during startup.

    Then try to copy / paste keyboard shortcuts.

  • Do not understand why "the node fpga Audio IN Terminal is 16-bit signed integer"?

    Hello

    I work with myRIO 1900 for my project of ANC.

    Audio IN of the fpga node gives its type terminal data as integer signed 16-bit. So, finally the exit on the nodes of the fpga is fluctuating between two values - 1 and 1. But I want the actual values of the audio data, I did not understand how to address this problem.

    Audio In on the side of RT gives type of terminal of data such as actual values, but I did not understand why the terminal of Audio In FPGAs is 16-bit integer. ??

    Please help me solve this problem.

    Thank you.

    If your analog range of +/-2.5 V.  32768 then--would be the equivalent of-2.5 V.  32767 would be + 2, 5V.

    If you get + /-1 V, then you should see somewhere between + / 13 107 on the analog input of the number I16.

    Basically, take the n ° I16, divide by 32767, multiply by 2.5.  You will have your analog input in volts.

    I don't know why you thing it's just rounding up to the-1 to + 1.  Something must be wrong with your code or configuration.

  • New computer. From PC to Mac... who's going to be a problem to reinstall Lightroom?

    Hello

    I think to replace my old laptop PC with a Mac book Pro.

    Currently I have Lightroom on my old PC (I bought the PC version of course).

    It'll be a problem for me reinstall the Lightroom, I bought on my Mac?  What I have to buy Lightroom again, but the Mac version?  It's going to be easy and free?

    What concerns me that it is not possible or difficult... I am also afraid that it can cost...

    Thanks for your help. Caroline

    It is usually simple. LR is cross-platform, so there should be no cost. You can install on Windows & Mac unless you have already done two activations. See if this video tutorial and useful link:

  • My STR-DN1050 goes to sleep every 19 minutes

    I now have my STR-DN1050 configuration in a 7.1 configuration and I am currently feeding inside my computer via a HDMI cable and output to a TV screen via the output CD/SACD.

    Every 19 minutes, regular as clock work, the receiver goes into sleep mode. This does not happen when you watch a BlurRay (at least as far as I remember).

    Anyone got any ideas?

    Hi are Paddy, we meet again!

    In fact you almost see right, that's 20 minutes to be precise!

    Your STR-DN1050 has a power save feature called [Auto Standby].

    In addition to this, there is also a sleep timer, but your problem is related to the expectation of the car which you can turn off if it is a problem. I don't know why this turns on when you use a PC connected, but most likely the receiver does not detect the source of the signal in the same way as a BD or DVD.

    You can read more about it and how to disable the manual online here:

    The receiver turns off automatically.

  • Monitor poster No. signal then goes to sleep

    I don't know if I write this problem in the right category but that's.

    Lately, whenever I turn on my computer (Pavilion Elite m9291d), my (HP w2207h) display will show a message "not - no Signal, HDMI - VGA signal". "." Then the monitor goes to sleep and blackens. I have to restart 8 times or more, and only by chance I could access my computer.

    Yesterday, I managed to go to the HP online support and to go to the control panel (in Classic view), go to the option to, and click "NEVER" in the screen and the computer advised to sleep options. Then after you save the settings, I'm supposed to go to Device Manager and disable the mouse and keyboard. After that, I have to restart my computer.

    Some can please help me and enlighten me with a few questions:

    (1) why didn't I go to "Classic view" and not the normal display of Vista?

    (2) if it is the problem of the screen, then why do I have to uninstall the keyboard and mouse?

    (3) Will cause the Vista Live Update upset to the setting of the computer?

    I have not tried the above steps again because today, I managed to get into the computer by chance. Help, please.
