• Satellite Pro A200 freeze, including the power button

  Had a complete system freeze last night - first tabs of Firefox, then, when I tried to call the Manager of tasks, CTRL + ALT + DELETE does not either. I pressed the off button several times, but couldn't turn off the laptop.

  After disconnecting the power cable, the power led is stayed blue and he was always running on battery, even if the battery led was off. I left the laptop (what can I do) until the battery has been emptied and it closes.

  This morning, it came normally, followed by this error message:

  "the exception unknown software exception (0x0eedfade) occurred at the location 0x7c812a5b.

  Followed by a screen of windows update updates have been made and the computer will restart soon (just in case where which can be connected - the night before, the symbol of "updates available" was in the shortcut bar too, and when it froze, I ran my virus check Spyware Doctor daily in the background).

  I rebooted the computer without other error messages and it has been fine until now, but I have no idea what caused it, and if it happens again. Any advice?

  > I left the laptop (what can I do) until the battery has been emptied and it closes.
  What else could do you?
  First of all, you could hold the power button for about 4 seconds and it would help tp close Notepad. Then you could reboot the laptop to check if the system is running correctly. However, it seems that it s running again.

  Believe me, it's really not easy to say what caused this problem system and I guess nobody here will be able to answer EXCATLY.
  In my view, there was a software problem that was solved by new reboot and a new update to Vista
  Strange things still occur and are not rare for me.

• (Model: D6000 ac750) Only the Power LED comes on after start

  Hello

  When I turn on my router, only the power LED comes on, no other LED lights. Ive been waiting for awhile as well, switching router on and outside, from time to time but its still the same result, only power LED lights

  I think this happened because of the failure of an attempt to upgrade my modem firmware, which I clicked on another tab, stop the download. After that, the modem turned off and only the power LED came on when I switched it back on

  any help would be apperciated, thank you

  NotGTAV

  I would say that the modem can be bricked you wish to contact Netgear phone support if it is still under warranty.

• 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.

• I have a computer that is running Windows xp and when I push the power button, it automatically restarts

  When I push the power button, it starts up but when I see the Windows xp startup screen complete the restart of the computer around and does exactly the same thing again and again, so I can't use it, please help I need my computer =)

  towelsrawesome,
  Thanks for posting on the Microsoft answers Forum.  The first thing I would say is to remove all external devices from your PC (except the mouse and keyboard) and then restart.  If she does not always correctly, then try to start safe mode.  Here is a link that explains the Safe Mode and how to start to it: http://support.microsoft.com/kb/315222

  Post back with the results of these measures.  Also, let us know if something has changed recently on your system (hardware or software) and give us some details about your system.  Let us know the make\model of pc and which package XP version\service you use.

• I bought my palm tx 3 years ago... problem: the power button work anymore; appear it only in a white light scanning when I press on the back 'home '.

  I've had my palm tx for 3 years now and I have had some problems with it. (because I bought it on the web, there was the guarantee) the first problem is the "power" does not work anymore? and the second, the scan goes blank (white) when I press one funds 4 (calendar or at home...). What could be the case of this defect?

  I bought my palm tx 3 years ago... problem: the power button work anymore; appear it only in a white light scanning when I press on the back 'home '.

  The warranty on a TX is only 1 year from the date of purchase.  Yours is way past the period covered.

  The switch was a small part of the TX.  Pressing any other button will turn on the unit, and it will turn off let it expire.

  There is a wire on the switch repair yourself, if you're a DO-IT-YOURSELF person here type:

• 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?

• Lenovo Y40: Must only press the power button two times to turn on

  Hello

  A few months ago, I bought my Lenovo Y40 on the Lenovo Web site and recently, to turn on, I have to press the power button twice. When I press that once, the Lenovo logo is displayed on the screen, but after 2 seconds it turns off. On the second attempt, finally the laptop turns on and the windows is started.

  In addition, rarely the phone stucks on the lenovo logo screen, is necessary to contain the power to reset.

  Someone had some problems like these describe above?

  Thank you.
  Pedro Lopes.

  Hello

  I contacted Lenovo's Support and they recommended to perform a full recovery of the system. Apparently, it worked because I did not suffer these problems since I got windows. Probably, there was a problem with the partition that has been responsible for the initialization of the system.

  Thank you, Pedro h. Lopes.

• macOS Sierra - press and hold the power button to enter the mode 'sleep'

  I recently updated my MacBook Air (13 inch, early 2015) model of El Capitan macOS Sierra 10.12. Before the update, hold down the power button / stop for 2-3 seconds, put the machine in standby mode. It does not properly after the update. Release the power button to switch to sleep mode works only once after each time you start the machine.

  I know he has an option to set the mode of sleep using Ctrl + button / stop and by selecting one of three options to restart, sleep and Shutdown, but who needs 3 more click click and is not fast. Also, independently of any application that is open, pressing the button walk / stop worked fine before the update, but now I need to be on the desktop even do Ctrl + Power button work.

  All patches available for it? Miss me the old way of put my Mac to sleep I do not remember if I did some tweak in my Mac, or was it a default feature...

  Greetings jainam2209,

  Thank you for using communities of Apple Support. It seems you want to put the Mac to sleep, but it does not always work.
  I would recommend read you these articles, the first article explains the ways that macOS Sierra is supposed to go to sleep.
  The second article can help if the computer won't sleep when you're trying to sleep.
