Power off and power on

Hello, I want to know when a user switch on or off the unit. It do not display any message.

public class app extends UiApplication implements SystemListener

{

public void powerOff() {}
TODO self-generating method stub
Try
{
Log.Debug ("I", "STOP");
                
UiApplication.getUiApplication () .invokeLater (new Runnable() {}
public void run() {}
Dialog.Alert ("OFF");
}
});
}
catch (System.Exception e)
{
Log.Debug ("E", "ERROR");
}
}
public void powerUp() {}
TODO self-generating method stub
Try
{
Log.Debug ("I", "WE").
            
UiApplication.getUiApplication () .invokeLater (new Runnable() {}
public void run() {}
Dialog.Alert("on");
}
});
}
catch (System.Exception e)
{
Log.Debug ("E", "ERROR");
            
}
}

}

EDIT: It is resolved, I added a listener.

public app()

{
Application.getApplication () .addSystemListener (this);

pushScreen (new appScreen());
}

Well oh - can mark you this as resolved then?

    I run windows vista on my pc, and every time that I turn it on, it just sits on the 3/3 update and will not progress. Even when I force my PC to power off and restart it, it continues to be. The first time he tried this update, I have dropped about 3 hours and returned to the configuration to update: stage 3 of 3-0% screen. Since it always happens. My pc is unusable because of this. What can I do?

    .. .my computer came pre-installed with vista, so I do not have a disk

    Not that I recommend a repair install, but the manufacturer was required to provide a way to reinstall Windows. If the computer came with a set of disks, there is a hidden partition restore (not to be confused with the restoration of the system) you would use to reinstall Vista.

    Assuming that Vista SP2 is not installed, I recommend you open a free support incident, NIC. See the link in my previous answer. ~ Robear Dyer (PA Bear) ~ MS MVP (that is to say, mail, security, Windows & Update Services) since 2002 ~ WARNING: MS MVPs represent or work for Microsoft

  • iPhone 5 turned off and won't turn back on

    Hi guys, my iPhone 5 turned off and won't turn back on despite my efforts to load. He doesn't have anything happen when the charge as the battery showing it is low or that the phone needs to be recharged.

    http://cosmouk.cdnds.NET/15/43/1445347217-iOS-low-battery.PNG

    It doesn't have this show in any every time I try to turn it on and even while there is no evidence a load.

    I corrected it when I contacted Apple support. They broke down the power and Home button to force restart it. Works fine now, battery has been replaced but because she is "consumed".

  • Pavilion dv6-6135dx: spread juice on laptop and worked fine until I turned off and tried to turn it back on.

    Not a lot of common juice but apparently enough hurt my laptop. He flipped on the upper right of the keyboard and I immediately wiped them all and the laptop seemed fine. I turned it off and when I went to use it, it not light. He also made a noise of sizzle on the top of the right side. Help!

    The sizzle is probably the sound of your motherboard short-circuit (die). The juice is probably infiltrated gradually down inside and when you applied the still-zap power.

    For what it's worth now no matter what time pours on a laptop, it must immediately be put out voltage, battery & power cord removed and the laptop placed upside down for at least 24 hours to evacuate just a little liquid.

    I wasn't doing anything particularly interesting when my computer just turns off randomly. I pressed the power button to turn it back on, I can hear the fan and things of the machine but nothing appears on the monitor. I pressed on and maintained the power button to turn it off and try again, it does not turn off. He is stuck with the computer on but a blank screen.

    Don't know what to do, I can't turn off, and he's not doing anything.

    Hi colhyena,

    I agree with Akuma. The same instructions posted by Akuma I found here:
    [What steps must be followed if your Toshiba laptop does not start? | http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=21]

    So that s what you can do and if it s does not you need professional help of an authorized service provider.

    Qosmio X 505 is newer model laptop so probably yours is still under warranty. In this case, the repair is free and you don t have to pay anything. :)

  • The battery will be discharged when my Satellite L670 is turned off and unplugged

    I have the Satellite L670-1john 3 months.

    the battery will discharge when the PC is turned off and unplugged.

    How to solve the problem?

    > the battery will discharge when the PC is turned off and unplugged.
    How to understand this?
    Does it means 24 hours battery is completely discharged or what?

    Battery loses power when the laptop is turned OFF and unplugged and there is nothing unusual.
    Enter the BIOS settings and disable Wake up on LAN.

    After doing this watch carefully what will happen and let us know if the battery will discharge both than before.

  • T420 screen turns off and turn it back on when the AC adapter / CC is attached or removed

    You are working on your machine, staring at the screen and the power failure... Yes - something quite common in these parts of the world... but no worries, the screen darkens slightly according to the diet plan and you hardly notice. Then, when the backup generator kicks in and the power is activated again, the brightness of the screen is back to your usual setting. Meanwhile, it is not a gene. Right?

    Well, that's what should happen... except that most of the time it doesn't work! Most of the time, the screen turns off and then turns on remove the main power and reinstall it. Note that this never happened once with T61 or T41p.

    Initially, I assumed it was because I had an external monitor attached... maybe it was to reconfigure something there? But then, it happens even without the external monitor. Then, I tried looking for the video driver updates... maybe this bug had been fixed to the... no luck there.

    So, finally, after having known this more often now, I thought I would get feedback from you all. Any advice?

    Check the Intel Media profile with the power settings. If a battery is "Maximum economy" mode then it should be in Exchange for 50 Hz to 60 Hz... Change it to balance or maximum Performance and see if its ever-changing from 50 Hz to 60 Hz...

    If all else fails, try updating the video driver, it might be a bug in the previous version of the driver.

  • Difference between "Auto off" and "Sleep" on LaserJet P1102W

    The user guide for the LaserJet P1102W indicates that the default Auto setting in the properties is 5 minutes.  "Automatic stop" drop-down list does not contain a setting of 5 minutes - rather it contains "never, 30 min and 1,2,4,8, & 24 hours."  However, the drop-down list 'Sleep' contain 5 min and other selections up to 1 hour.  What is the difference between auto-off"and"Sleep ".

    After the installation of this new printer, the default settings have been = 5 Minutes ' Sleep' and 'Auto off' = never

    I have several computers around the House than any print to the same printer.  I want to always available for printing without issue in the basement to activate it, but yet they want more economic mode.

    What is the difference between 'Sleep' and 'Auto off' and how should I put them in my terms of service desired?

    Thank you.

    Hello

    I understand that you are looking for some explanations between the Sleep and automatic shutdown of the Laserjet P1102W printer. I would be happy to offer you answers!

    For your desired operating conditions, I think that you already put as you would like. Standby essentially puts the printer in a State of very low power consumption, but the printer can be awakened from this State by sending a print job (meaning you don't have to go to the printer to remove it from that State). The auto-off function off the printer completely after a period of time. The only way to take the printer out of State would be to go to the printer and press the power button.

    To have several computers connected to this one printer I would recommend leaving the auto-off Never and Eve to what you think is the best. As I said, the printer will wake up fashion 'sleep' and accomplish what you ask without physically going to the printer.

    Hope this helps, have a nice day!

  • Sony Bravia 55 '' goes off and lights repeatedly

    Hello

    I'm sure this has been asked and answered many times, but I thought would like to ask once again accelerate things.

    We have a Bravia KDL-55HX800 is only 3 years old 55 "and out of nowhere, he began to turn power off and back on.   Even if you switch off and the light is red, you can still hear a relay or something cycling power on and off when the unit is plugged.

    Do a Google search that I realized this thing similar happened to MANY owners of products Sony and Im very disappointed, because we paid $ 1500 for this TV and couldve bought a Walmart cheap set for half the price.  We spent the extra money on Sony because of the reputation.  If I wouldve known my $1500 would have only gotten me 3 years of service I most certainly would have gotten the throw all of Wal-Mart.

    After a bit of reading, I keep seeing on the firmware update and other, as a computer scientist to talk to me I do not see why this changes nothing because all is connected to the same power source and Tivo it has been connected since brand new.  No change in the material either.    Only now, the game has a problem.  A problem. apparently a lot of people were undergoing.

    If I had to guess, Im as the answer to all this is Im just out of luck, good luck finding a technician who can fix this flawed TV set.   (I look at places in the Service Center authorized Sony by my zip code, but they all have horrible comments/reviews by previous guests) But Im hoping that since he is in fact a Sony Forum they can explain a repair and why their product worked only 3 years?   We can expect future elements of Sony?  And finally, why a person never would pay the huge price of Sony again if their product has the life of a disposable product from a big box retailer.

    Television has been disconnected since the beginning of this episode, because even when it was set to OFF with the red light, leave plugged in, you could hear something cycling again and again inside.   That did not sound good at all, so we left it unplugged.

    I did as you asked, no change.

    However, to do a lot of Google searches, that we can on this:

    http://www.ehow.com/how_5855646_reset-Sony-BRAVIA-TV.html

    This has fixed the problem and so far it works normally.     Before he would not stay on for more than 10 seconds before cycling off power, remove and then replace slot, so we were unable to do any update.   (Wasn't enough time to get to the right screen to update) But since doing the procedure from the above link, we went ahead and updated the software also.

    You can recommend this procedure to those who have the same symptom we had.

    Hello untech,.

    I see it's been a while since you have posted with us on the HP Forums.  Please, let me take a moment to say "Welcome Back".

    I see that you have a problem with the printer l ' auto turn off and not turning it back on.

    You happen to have the printer power cable connected to a power strip/bar?  If so, please try to connect the printers power cable directly to a wall outlet.  Here is a document that explains the problems when connected to an uninterruptible power supply/Strip/surge protector power.

    The printer in the document is a LaserJet printer but this document is intended for HP products in general and only use the LaserJet printers for example.

    I'll also include a document indicating when the HP printer will not be running or to respond when the power button is pressed.

    If by chance the problem is not resolved after you complete the steps described, then I would say call the HP Technical Support to see all the other possibilities for you. If you call in North America, the number is 1-800-474-6836 and for all other regions, please click here: click here.
