3 peripheral USB connected to the Macbook 4.1 computer tells me to restart using the power button / stop?

I went to record a live concert, and I need to use a single interface to record the members of the group with microphones near directly to a computer and another interface running for my model of Macbook 4.1 end of 2007, to get signals from the map of the House.

When I plug my converter USB 3.0 AD / DA in my Macbook 4,1 - the computer sends immediately a window indicating to me to "reboot" the computer using the power button / stop. Ideas or comments about why this happens?

I read on this forum that USB ports should work with retroactive effect, or accept USB 3.0 devices, but just use a speed 2.0?

Thank you.

It could be that it is a requirement of your converter AD / DA she needs to be present at a properly accessible to the OS X when startup sequence it is plugged into a USB2 port.

Its also interesting to note that, well that peripheral USB3 can be plugged into the USB2 ports... it could be that your device may not work properly unless it is used with a port USB3... for reasons of bandwidth or even certain types of power supply.

But to be sure...

Which converter AD / DA are you using?

  • power led on the rear of the computer the power button / stop turns on, then turns off.

    I have a HP TouchSmart 610-1015xt.  The light on the transformer power is on, but not exactly brilliant (I think it's good, but not sure).  The light next to the power input is on.  When I plug in the power, the power led lights up for a couple / few seconds then turns off and does not turn.  At no time the computer capable of running and it does no whether noise (no fans, no beeps, no attempt to start.

    Any suggestions?

    Figured it out.  Apparently I have reset the battery internal and then unplugged the power button circuit and then he started upward.  The only problem is that now it will restart automatically every time it is closed or even sleep.  I'll start another forum on this issue.

  • Satellite L550-1CW does not start by pressing the power button / stop

    I have a Toshiba Satellite L550-1cw that won't start, lights up when I press the power button all the lights at the front, the fan starts and he is looking for a HARD drive for about 2 seconds and then stops.

    I tried a new HARD drive, but the same happens.
    I was told that all this must be ignored and buy a new one that is not an option.
    I love this laptop and want to run again as this is the best I have ever owned.

    Help, please

    Andrew

    Can you give us more information on this vulnerability?
    You see something on the screen after pressing the power button?
    You can access the BIOS by pressing the F2 key immediately after switching on the device?

    Despite this whole issue, I think that if nothing is visible on the screen it could be a serious problem with one of the following: RAM modules, motherboard, CPU/GPU.

    From my experience the RAM memory modules are not very expensive (2nd hand might be good enough) and the replacement isn t very delicate in the case where the faulty memory causes this problem, the laptop could be set for a little money.

    But in case of problems of motherboard, laptop repair procedure could be very expensive.

  • Satellite A200 23W stop seconds after pressing the power button / stop

    Hello all :)

    I just bought a laptop Toshiba Satellite A200 23W a few hours ago.
    I turn it on and let it complete the installation of Vista.

    After the installation of Vista finishing it asket to resturn laptop and from that moment, the laptop is "dead".
    After pressing on restart the computer (from Vista) computer turns off without problem, but he never did it again!
    After a few minutes of waiting, I tried to start it by pressing the power button.

    Now when I press the power button, I can hear the HDD work and most of the time until I see something on the screen of the laptop computer stops!
    Now, I noticed that both the battery indicator AND the DC IN light are hot flushing and stop Flash at times.
    Reading the manual, I guess that the DC IN indicator should Flash in all not well.

    I tried to uninstall the battery and try to start the laptop, but in this case I can't even listen to the HDD, commissioning!
    I try to unplag and replag (on the laptop as well as Jack) power cable but again no result.

    Any ideas of what past?
    Thank you very much

    I don't know what the problem is here and, in my view, should not be so important to you. Contact your dealer as soon as possible and to talk with him. Explain the situation. You will get may be new notebook. Otherwise, please contact the nearest authorized maintainer and let check your laptop.

    The laptop is brand new and it should work. Please do not wait too long.

  • Satellite P50-B-103 - light around the power button / stop does not work

    I bought this laptop a few days ago, and early on, I noticed that the light around my power button does not work.

    so now I'm in dillema it back or not?

    Everything works well, but because of the price, I expected to work correctly.

    And what is perhaps the reason for this?

    TNX

    As far as I know that the power button or to be more precise, the margin around the power button should be lit / lighted.

    In my opinion its not serious problem but if there s a problem for you and you are not satisfied with that, I recommend you contact the dealer to replace the unit.

  • Compaq 6710 b: my HP Compaq power on only when I plug in power. Don't turn on with the power button / stop!

    I have a laptop HP Compaq 6710 b... Its more than 6 years...

    The problem is really annoying... The laptop powers on only when I force taken into the spindle of the charger and the laptop works very well after that...
    But the laptop never turns on when I try to power by pressing the power button!
    I did not understand the reason why...

    Any thoughts on this problem?  Help!

    There are no settings in the BIOS that affect the use of the power button.

    The power button works at the level of the material (firmware).

    By pressing the button translates the action of the Commission of the conditions of the logic system.  There must be voltage at specific points in the power circuit. If the voltages are not present, then the power button does not work. This can be caused by a failure resistance, mlcc capacitor or a bad solder joint, if the power button has been tested and shown to work normally. Fluff even could cause this to happen. This can help out-performed by Visual inspection and using a multimeter.

  • PowerEdge T410 won't do anything when you press the power button / stop.

    My work has recently retired this t410 server. It worked without any problems when he was arrested. I had to remove and destroy the hard drives from the system. After that, I was allowed to bring home for my own use. I installed a new sata drive and plugged into the power supply and a free sata port on the motherboard. I get nothing when I tried to boot the system. This version has the unique power. Power light only lights up when you press the test button. System fan is going at full speed, but stops when you release the power button. Also on the control panel lights 1,2 and 4 and HDD power on and turn until the test button is released. There is a single green light lit on the motherboard, while it is plugged. Apart from that, I have no response when you press the main power button. Can anyone tell how to try to get it up and running again.

    -Who-

    I have not received the answers more so I think that this issue is ignored. So I'll let everyone know what finally happened. I solved my problem after a lot of electrical testing. I found a diagram of the arrangement of the power dell power supply pins and I made myself the best possible meter test. After several rounds of tests, I found several pins that did not have the right voltage. I bought a new power supply. I installed and replace everything. I plugged into the system and it auto fed on itself. I loaded from an OS and it works perfectly.

    -Mayur gala

    Hi Mayur,

    Welcome to the community,

    Sound signal can be used as a diagnostic indicator. The computer may emit a series of beeps at startup if errors or problems. This series of beeps identifies a problem and is called "beep code".

    See the table below which shows the beep codes and the possible problem:

    Overview of beep Code
    Beeps Description Possible cause
    1 ROM BIOS checksum failure The map system, covers BIOS corruption or errors ROM failure
    2 No memory (RAM) detected Memory or memory slot failure
    3
    • Chipset error (North and South Bridge error)
    • Time-Of-Day Clock test failure
    • Gate A20 failure
    • Super i/o chip failure
    • Keyboard controller failure
    System board failure
    4 Memory read / write failure Memory failure
    5 Real Time Clock (RTC) power failure CMOS battery failure
    6 Video BIOS Video/smart card failure
    7 Failure of the CPU Processor failure
    8 LCD SCREEN Failure of the LCD

  • HP DV6 6115TX UP STARTS NOT WHEN I PRESS THE POWER BUTTON / STOP NOTING HAPPENS

    LAPTOP: HP DV6 6115TX

    1. WITH THE BATTERY AND CONNECTED AC-

    WHEN I PRESS POWER BUTTON NOTHING HAPPNS ONLY INDICATOR LIGHT NEAR THE POWER SUPPLY BECOMES WHITE AND STAYS ON UNTIL I HAVE TO REMOVE THE BATTERY.

    2. WITH THE BATTERY ONLY

    WHEN I PRESS POWER BUTTON NOTHING HAPPNS ONLY INDICATOR LIGHT NEAR THE POWER SUPPLY BECOMES WHITE AND STAYS ON UNTIL I HAVE TO REMOVE THE BATTERY.

    Hello @HPDV6-6115TX ,.

    Welcome to the HP Forums!

    I understand that you laptop is not turning on.

    If the laptop has no power, other than the AC adapter connection indication, there is little that can be done.

    The adapter ring is HQ shows a white LED would suggest the adapter supply fine and offer pay-per-view mother, or at least the internal power connector. This means it is a flaw in the motherboard of the laptop and most likely requires a repair.

    You will want to check that the RAM and HARD drive are in place and connected, as well as internal power cable. You can do it by following your product Maintenance & Service Guide.

    HARD drive: Page 62.

    RAM: Page 66.

    Power cable: Page 83.

    If it does not, you will need to contact the HP support by phone for service options. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.

    Hope this helps!
