I can't unlock power button on HP2509m monitor.
How to turn it off?

Hello @kanin,
I understand that you are having issues unlocking and turning off your HP Pavilion 2509m LCD wide-screen monitor. I am providing you with some steps you can try below:
Step 1. Hold the power button down for 30 seconds
Step 2. Unplug the power cord from the back of the monitor and the wall
Step 3. Hold the power button down for at least one minute
Step 4. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 5. Press the Menu button on the monitor
Step 6. Navigate to the Factory Reset option and select it
Step 7. Try different cables between your computer and monitor.
If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836.

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

How to remap power button to stop sleeping?

I have a new macbook air, but I keep running into the issue of pressing the power button .
With the new OS system, I hit the thing, and it turns the computer to sleep. This wouldn't be as bad if
I press the power button over and over again to fight the thing to turn back on.
Anyone found a way to stop this? Annoying as ****.

I guess I wasn't clear. I am aware that you can still bring up the dialog box if you hold down the button. However, I wanted to get rid of the feature of pressing the power button, and having my computer turn to sleep mode.
It's irrelevant, and turning it back on from sleep mode becomes a major issue.

How to replace power button

I have a PPC mac mini and a matching La Cie HD which stacks on top. This serves as my home music station. BUT obviously we want all the cables out of sight and this means they all face to the back as does the power buttons for the mac and the HD. And this means I'm the only one in the house who can fiddle blindly round the back of both drives to turn them on. Even I am getting fed up trying to 'feel' for both of them, they are the same 'dimple' style.
What can I do to replace them with more visible and positive switches. I don't much care if they aren't aesthetically pleasing just that they are visible and positive, possibly even mounted on top of the stack with extended wiring if you get my drift.

Why not just sleep the Mac and wake it up with a mouse click or key stroke instead of shutting it down. Not only is it easier on the hardware than numerous cold boots, but you can start working enjoying it in seconds instead of minutes.
FWIW' I sleep my Mac's 24-7 and never fully shut down any of them unless I going to be away for several days.

HT201401 How to fix power button??

Is there anyway to fix the power button on iphone 4...its like pressed in and need to press it a bit hard so tht screen closes? Is there anyway to replace it from apple store or anything ??

Hard to say, since you made no mention of the problem.
Maybe if you were to share what it is that you want to "fix", then someone could help.

HT4972 how to press power button for iphone

I can"t open iphone

Like any other button, you place a finger on it and press.
What does this have to do with "opening" an iPhone? By that do you mean getting past the lock screen? Carrier unlocking the device? Or did you possibly mean physically opening the device (i.e. opening the case)?
What does this have to do with iPhones in the Enterprise, the forum to which you posted this cryptic question?

Powering on without presing power button?

Hi,
On my old G5 tower with an old ADC Cinema display, the G5 was hidden under the desk and I used the power button on the monitor to power on the Mac.
Same monitor, Apple ADC-DVI adapter, Mac pro. No good - not working!
So, is there any way I an either get this working, OR is there any other way I can get a way of powering up my Mac Pro via some other route that doesn't involve reaching uncomfortably wawy under my desk and flailing about trying to feel for the power button?
Thanks,
Dom

I would probably move it from under the desk unless it gets good ventilation, doesn't pull in dust, and exhaust has some place to go.
All the new Apple CinemaHD will do is turn display on/off or sleep/wake the system.
Never power off and set it to auto boot at 8 AM?

23" ACD Power Button Issue / Display Options Missing

One time my dual 2ghz power mac froze upon coming out of sleep mode so i held the power button to power down the computer, but before i did that, i touched the power button on the side of the monitor, hoping to somehow bring up the password prompt out of sleep mode but the screen stayed black and the cursor / ball would just spin for minutes.
I used to turn on / off my computer and the display would automatically go on / off with it, but now i have to manually power up and down the monitor. And in the system preferences, there is no longer the options section where i can choose what the power button on the monitor does.
Can anyone help out with why this is happening? A million thanks in advance.

Your computer no longer has USB connection to the monitor. Do the USB ports on the back of the monitor still work? Sometimes unplugging everything, including the power cord, from the monitor for a while will fix it temporarily.

3 day old iMac power button spongy.

Hi all!
I noticed this on day one, but it wasn't until I got to another iMac to try the power button that I noticed just how spongy the power button was on my new iMac. At £1,700 I would expect every aspect of the machine to be perfect!
Anyway, I think it would need to go back to the store to be replaced/fixed. I've invested a LOT of time into setting everything up over the last few days. My question is, if I got a replacement iMac would this all need to be done again?
Thanks!
Mark

I'm new to OSX, and was wondering if they could migrate everything to a new mac and I'd have that one, so that's why I would "expect"/anticipate otherwise.
Thank you for the clarification. No, they won't do that.
There are many ways of implementing a power button, and it's likely that yours is working exactly as it should. Apple sources their parts from a variety of vendors and not all power buttons have the exact same tactile feedback. If you think something is not right, by all means have them evaluate it.

Broken power button on iMac G4

I am considering the purchase of this iMac. It has a broken power button. What are the implications of this? The present owner says that he just plugs it in and it starts up, and that besides he just leaves it on all the time anyway. How big of an issue is this? Can you advise me on how easy a power button might be to repair or if it is very necessary to repair it (assuming their is a workaround-keyboard startup?).
Thanks in advance!

Given the said iMacG4 model and year are not discussed, one possibility
may be to buy a third-party for Apple Macintosh keyboard with power key.
If nothing else is wrong with the computer, it may run awhile without trouble;
but access to the physical power key (on the logic board; may be hard to
buy the part by itself to replace it) is handy in troubleshooting or restarting
when something freezes up. Unplugging and re-plugging the iMacG4 to
make it go/make it stop is not recommended. Issues can result; I am
aware of a few problems in the G4 and earlier G3 iMacs and others, due
to the owner unplugging the machine instead of performing maintenance
or repairs in a timely and orderly fashion.
Since that machine is likely no longer covered under an AppleCare Plan,
you could either have someone else eventually replace the logic board
or other parts as you find them; or if you are technically minded and have
a good attention to detail with adequate work habits, fix it yourself. The
service manual, a download in PDF for techs, may still be available. It
was intended for trained personnel, and damages worse than the first
problem may result from improper procedures being done inside the iMac.
That said; good luck & happy computing!

How do I turn off the Power button Lockout on my HPw1858 monitor?

How do I turn off the Power button lockout on my HPw1858 monitor?
This question was solved.

Hi,
Power Button Lockout is displayed.
The monitor's Power Button Lockout function is enabled.
Press and hold the Power button for 10 seconds to unlock the Power button function.
If the above doesn't work then try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up.

Aside from Wake on LAN, how can I turn on my S10 without pressing the Power Button?

Hi,
FIrst of all I have not tried Wake on LAN on this S10 of mine, yet. I don't even know if it will work or not.
Anyway, this is my main concern. I'm planning to mount my S10 on the back of my monitor, I'll be putting a wire mesh kinda box that will hold it. I will then hook the VGA monitor/audio cables to my S10. I'll also be hooking my wireless Keyboard so it will look clean as possible. With this setup, of course, the LCD lid will be closed and I'm thinking of ways on how to turn it on with the Lid closed. I'm currently finding ways on how to do this? I was hoping NOT to go to the rear of my monitor >> lift the S10 from the mesh box >> press the power button >> close the lid >> place it back to the mesh box mount.
The wireless keyboard has a power on option (I have Logitech MK300) but does NOT work. Would a Wired USB keyboard work?
Fortunately, I have a deskop computer (which has its own monitor) that will sit beside my S10/Monitor. The two computers (Desktop and S10) will run independently.
What do you think guys? What options can I go with? Is my only hope Wake On LAN? Oh yeah, it is even possible with the S10?
Maybe there is a USB device or a hack that can be done (not voiding the warranty)?
Thanks!

Yeah, I just noticed it So does this mean I can't wake my S10 thru LAN right? Anyway, do you have any suggestions? I'm looking for a Docking Station, but I can't find any. Can a USB replicator turn this on? Any ideas would be greatly appreciated

Monitor message" Power Button Lockout"

HP ZR2240w Power Button lockout, monitor powers off

This is regarding a HP ZR2240w Monitor. Occasionally "Power Button Lockout" will apear on the screen and about 10 seconds later the monitor will lose power. This occurs with any type of input (VGA, HDMI, DVI). If the power is left plugged in, it will sometimes come back on at random times. Sometimes unplugging the power and plugging it back in will resolve the issue, but usually only stays on for a few minutes before repeating the process.

I understand you are having difficulty with the Power Button Lockout on the monitor. I would recommend you follow the steps I have set out below:
Step 1. Turn off the monitor
Step 2. Unplug the power cord from the wall and from the monitor
Step 3. Hold down the power button for 1 minute
Step 4. Plug the power cord back into the monitor and ensure it is plugged directly into the wall
*** If the issue persists try the next set of steps.
Step 5. Press the MENU button on the monitor
Step 6. Navigate to the Factory Reset Option and reset the monitor
