600xt won't occasionally won't wake/power-on... green light on the power adapter is out... strange

Within the last 3 weeks or so our TouchSmart 600xt has goes into an odd state 4 different times... after being left unattended for some time we'll return to find the machine appears to be off & will not turn on via pressing the power button (the button on the upper right edge of the screen.) It typically sleeps after 20min, and if sleeping he power button will be glowing orange... in this case the light is off entirely. Also, when this occurs the green light on the power adapter is not lit. The power adapter behavior is quite out of the ordinary; its light never seens to be off, even if the PC is shut down completely. But it is when this happens.
The only recourse seems to be to unplug the power adapter, then plug it back in, after which the green light on the adapter lights, the power button lights, & the machine can be turned on by the power button.
Concerned we will lose some files if the shutdowns keep occuring. We've had the machine nearly a year, and this is new behavior in the last 3 weeks. However note that not during every sleep cycle does it occur. (The machine goes to sleep after being unattended on average 6 times daily and this has happened "only" 4 times it slept in the last 3 weeks.)
Thoughts? Some power-saving circuit in the power adapter gone awry perhaps?

I would suggest buying a new power adapter.
I have more HP devices than you'd expect.

My A'Extreme sometimes won't connect to my MacBook Pro even if I have a green light on the device . I can unplug the ethernet cable and reconnect and it will work fine. all diagnostics say there is nothing wrong. Any ideas ?

This is more about your modem then anything. Sometimes you'll need to unplug and plug back in your modem. Consider it a glitch from the ISP or just the modem in general.
when I need to turn something off then on I try the modem first. This when I'm not doing any ware and tare to the device.

Spilled Drink - Laptop won't recognise power adapter + screen backlight

Hi.
The other day, I had my 17" MacBookPro in a satchel bag, but made the foolish choice of leaving my Lucozade (Orange flavour if that helps!) in the bag.
Obviously, the Lucozade burst, submerging around two inches of the laptop, there part where the screen connects to the laptop, and submerging the power adapter port.
Now for around twenty four hours, the power adapter charged the laptop, but unfortunatly, the backlight on the screen suddenly didn't work, as in you could very faintly see it, but when you try to turn the display up, nothing happened.
Twenty four hours after the spill, the power adapter failed. I'm pretty certain it isn't the power adapter, which means the problems seems to lie with the power adapter port.
Now I opened up the laptop two days ago, (three days after the accident), and cleaned what ever Lucozade there was, and just in general cleaned up the insides of the MacBookPro (which is now around two-and-a-half years old.) Unfortunatly it didn't work.
So currently I have a MacBookPro with no battery power, and no screen backlight. So what i'm asking is for any advice at all!
Is it worth taking it to an independant laptop repair business? Would they be able to do much more than me?
Should I take it to a Mac shop? Would they know what to do?
Is there anything I can do myself?
Anyone else had a similar experience?!
Thanks a lot.
Christian.

I think the problem may be with the inverter board or cable. Do you have access to an external display? Maybe one you could borrow? If so, hook it up and see if you have good video on it. If you do, that would indicate that the video chip on the logic board is OK. And if you can get good video on the external, it would be a good opportunity to run the Apple Hardware Test.
One thing is that you really need to remove all traces of the Lucozade or you could have further issues on down the line. You could practice on the I/O board you removed. Flush it thoroughly with distilled or deionized water and dry it thoroughly (this could take weeks, maybe less if you have a warm dry place for drying). You could try cleaning any affected part this way, and it's possible--though not certain--that it could work again.
You probably have found ifixit and PowerBook Medic by now. Let me give you another link:

This is an index--you will have to find your specific manual and download it. But I think you'll find it useful.

Why my iPod Shuffle 3rd won't charge until full (green light on)?

I have new iPod Shuffle 3rd gen, My problem is my iPod won't full charge, I was tried to connect my iPod into my MacBook Pro more than 12 hours and I hope the green light (full charge) will be on. but the result still the same.
I tried to hear via voice over and said that battery only 75%
Any body have the some problem? and how to fix it?

maybe you can control the room temperature.... i try to charge iPod shuffle beside the mini fan, so heat from shuffle can blown away... or maybe, you can charge the iPod in Air Conditioned room....
i think this device have a mechanism to cut off the charging process if device temperature too hot. such a safety system so this ipod won't burn out when overcharging.
i hope it can help you...
and trust me IT WORKS....

PB wont wake up. Sleep light in the front is constantly on

Hey guys, i'm having a big problem with my PB 17. It wont wake up at all from what I think is sleep. When I open the lid, or when I push the power button or even hold down the power button, the flashing blue/whiteish light stays on and never goes away. Even when I close the lid or disconnect the battery from the PB, the light still stays on. The Hard drive is off, the screen is off, its not making any noise at all. Just a nice little light on the front. Can't get anything to go.
Any one have any ideas?
Thanks

Reset the PMU: it didn't work.
Removed the list of PMU as suggested by another discussion in the form: it didn't work.
It was just getting worse and worse that the computer fell asleep every 5 seconds.
I took it to the Apple Store. The guy at the Genius Bar immediately said that it's due to the top case, which was exactly the same as what I found out from Google and Apple Discussions. Two days later I received the call regarding that the computer is ready to be collected. The topcase has been replaced. The computer has been working fine so far.

My Mac mini won't read my SanDisk ultra MicroSDHC through the SD adapter.

I have a SanDisk ultra 32gb MicroSDHC card that I use with my Galaxy S4, and which came with an SD adapter. The problem is that when I try to Plug the card, through the adapter, into the SD port on my mac mini it simply won't read. nothing shows up on my desktop or launchpad and also no windows pop up. Does anyone have any solutions? I have a late 2012 Mac mini running Maverick version 10.9.3.

What is format of the card?
Does it appear in Finder?
Likely the format is not readable by the Mac
Open Disk Utility and see if it is listed there

Photos won't let me edit my photos. The adjustment controls black out when I click on "Edit".

Photos no longer let me edit my photos. When I click on the "Edit" button, the controls on the right side would appear, but they are darkened out and cannot be selected. Please help.

deleting them may be what gave you the mess.. I am torn- if I give bad advice at this point, going into the realms o knowledge where I am a newcomer might get me yelled at.
If it were me, and I was impatient for a cure, I would open iPhoto, connect the memory, open two finder windows- and from the window showing the memory with the saved pics on the external, drag to the finder window showing iPhoto, the pieces you had deleted, and see if they can get back into place and act like they were never moved.
The only other thing I can think of would be make a back up of all of iPhoto, then delete it completely and download a replacment, and never mess with the library again. HOWEVER: I do not know if apple condones or allows that- so you maybe need to get to a genius appointment at an apple store near you, or try to do the phone help.
Like I said- I have seen many warnings to not mess with the memory of iPhoto.... I guess this is an example of WHY.
I apologize that I do not have an easy way out of your nightmare.

Won't turn on, shows green light

So last night I was playing with my phone, using up the battery, then it notified me that the battery was low. I stopped using it and just turned the display off and put it in my pocket. I went to my room and I tried to turn the display on, it didn't work. I assumed it died so I plugged it into the WALL charger. It showed the green LED light on the top of the phone, but it still wouldn't turn on. I then just went to bed and let it charge ALL NIGHT. I woke up to see the Motorola symbol on, and it was booting. Then I went back to sleep. Then I woke up later and it was the same as before, it wouldn't turn on, and the green light showed when you plug it in.
I've tried leaving the battery out for a few mins, taking the battery and SD card out and putting them back in, I've tried just letting it charge, nothing is working.
Also when I plug it into the computer via USB, it shows the green light as well, but the computer doesn't even notice it's plugged in. The computer doesn't respond to it being plugged in what so ever.
I also did some re-search before posting this! Looking at forums where people at the SAME problem, and none of their solutions are working...

I just received my third Droid X today. I returned the first one after a month because of the blank screen/green flashing light issue. I had the 1st replacement for a week and a half before the camera wouldnt load and the bottom half of my screen went out...started flickering at first, then completely blank but still functional. Just got my 2nd replacement Droid X today, put in sd card and battery and back to the old black screen and green flashing light. I am absolutely livid as I use this phone for my business. I will be taking it in to the store tonight and I wont leave with a Droid X. I expect some sort of reparations.
I take it they never replaced your battery or charger?
Black screen and green light usually goes right along with charging issues. Are you using the cable and wall charger that came with your device? If it is an issue with the charging cable I would have them replace it and the battery.
As for getting your device changed, if you are out of your 30 day no questions asked period, it's not going to happen without you forking out more $$. People usually get mad when I write this, but it's the truth.

My MacBook Pro Retina won't turn on! Yesterday I installed the new updates.

So it's fully charged. I used it without any problems last night, then shut it down. This morning when I tried to turn it on, it won't. I have Lion installed and am up to date with all of the software updates. There is a green light in the AC adapter. What should I do??

I know this post is from back in September of last year, but I wanted to comment for posterity to say what worked for me with my July 2012 retina MBP refusing to turn on. From the link preludio posted above: http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US
Use the "Resetting the SMC on portables with a battery you should not remove on your own" method (ie., for all Macbook Pros early-2009 and later). Worked perfectly for me:
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

MBA won't wake from sleep while connected to VGA Display

Since a few days I'm using a VGA Display connected through the official Apple Mini Displayport - VGA Adapter. However, when I put my MacBook Air to sleep and then close the lid (otherwise closing the lid will just continue on the display). Keeping the monitor attached, it won't wake from sleep anymore. Disconnecting the adapter at that moment won't make any difference. What troubleshooting steps can I make?

I usually...
Take out the charger
take out the battery pack
reinsert the battery pack
Then click the power switch
(if you have low battery I'm sure it would be a good idea to plug in the adapter again

MacBook won't wake up from sleep / boot up.

My MacBook has trouble waking up from sleep, and sometimes booting up from a normal shutdown. When I open the clamshell after I put the computer to sleep, the indicator light doesn't blink, but is lit up, and the screen is completely blank. Pressed all keys, and still it won't wake up. I've had the same problem with booting up the computer from a normal shutdown as well. I've tried holding on to the power key and doing a hard reset, but nothing seems to work. However, I can't seem to pinpoint the cause of this problem, it seems to be completely arbitrary. Sometimes, it wakes without a problem, and sometimes it just stays in "zombie" mode for .. extended periods of time.
I've also resetted the PMU, and the NVRAM as well. I'm not sure how this could affect it, but a few days ago, my CD drive broke. When I tried to boot up, the CD drive seemed to be turning to find a CD, and couldn't boot up. So I took it to the Apple guy and got the CD drive removed completely. I took the MacBook back to him with this waking up problem, and he says it's fixed, but it really isn't.
Help! I can't

I can't boot up MacBook and I,m wondering if you tried SafeBoot. I went through the process, got the progress bar, then nothing. Just more blue screen and gear spinning.

Suddenly won't wake from sleep.

All was well but suddenly the Powermac G4 (gigabit ethernet) won't wake from sleep. Tried resetting the PMU (battery out and button pushed). Tried resetting the PRAM. Tried deleting the energy preference file. Even tried installing 10.5 on this old baby (runs just a slowly as ever, but startup takes an age). Can't run hardware testing because there's a bad firewire on the motherboard and it just stops there. Don't know what else to do. Why? this is my music server and it uses just as much power as my refrigerator if left running all the time but only needs to run when playing music.
400MHz PowerPC G4 (2.9)
boot rom 4.28f1
two Maxtor ATA drives
Studio Display with DVIator power and adapter
1G RAM (sure, I'd like more)
one PCI card with FW and 2 USB
one PCI card with 4 USB
Airport card
Modem
System Power Settings:
System Sleep Timer: 60
Disk Sleep Timer: 10
Display Sleep Timer: 10
Sleep on Power Button: No
Automatic Restart on Power Loss: No
Wake on AC change: No
Wake on Clamshell Open: Yes
Wake on LAN: Yes (does not respond)
Wake on Modem Ring: Yes

If the SMC reset doesn't work try this.....
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Try resetting the PRAM. This should reset the NVRAM on most machines, which is the suggested fix.
Then put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong. The restart is very important.

IMac won't boot if Firewire device is turned on/won't wake from sleep

I am sometimes having an issue where my iMac won't wake from sleep; after I restart the iMac wont reboot (grey screen) until I power off the LaCie 300GB Firewire drive. I just bought this iMac a couple of weeks ago but the Lacie was on a PPC G5 Tower before and always was OK. I have no other Firewire devices to test the port with so my resources are limited. Anyone heard of anything like this ?

I noticed there is a firmware updater for LaCie drives. I don't know if it applies to your product, but here it is

Fan runs on HIGH and won't wake from sleep--it freezes!

I have a G5 (Power PC, g5, Dual 1.8 GHZ with 1.25 GB SDRAM, and Mac OS X 10.4.10-phew!) and I recently: added more USB ports using a PCI card, and purchased a non-Apple 22" widescreen display.
Prior to adding USB ports, I was using a hub that ran off its own power source, and used a Samsung 19" monitor.
My situation now: everything starts up fine, but ultimately the fan will kick in at SUPER HIGH and won't stop. I can put my Mac to sleep--which stops the fan noise--but then it won't wake up.
I have run the Apple Hardware test and everything checks out OK. I've also reset the SMU according to directions from this forum; AND I've vacuumed out all the dust bunnies.
The fan runs so loud and so high it sounds like it's an airplane that's about to take off.
Short of bringing in my Mac to a technician, can you recommend anything? My Mac has been glitch free up until now.

I have a G5 (Dual 1.8/2.5GBSDRAM,10.3.9) that I'm worried about. After stepping away from my machine for an hour, I came back to it and it sounded like the fans were about to blow they were revving so high! My screen was frozen and non-responsive, so I did an immediate shutdown via the power button. I let it sit for an hour or so and it would not reboot (Got the power on chime but nothing...except the three repetitive quick pulses of light from the power button). I knew that it meant it was a RAM issue. Did the old unplug trick and SMU button trick, nothing. Have 2 original 256MB and 2 6mo old 1GB pairs. Pulled the #2 pair then booted (failed), then swapped the #2's and seated in #1's slots...no luck, still get the three flashes on the power button.
All the RAM was seated firmly...so I don't think it's the RAM. Am I looking at a logic board or power supply failure? Is there an alternative I'm missing?

22" ACD won't wake from system sleep

Someone gave me their old G4 Dual 450, with the stock ATI Rage Pro 128 video card. I took a 22" Apple Cinema Display (ACD22, we'll call it) which worked perfectly with a G5 1.6 and hooked it up to the G4--using the handy, all-in-one ADC connector. The display looks great and works perfectly with the G4, except for one thing: If you do *manually invoked* sleep on the G4, the ACD22 won't wake up.
If you let the display go to sleep via its own timer (set in Energy Saver), it will wake via mouse/kb input. (Keyboard is plugged into the ACD22, mouse it plugged into the keyboard.) But it will NOT wake up if you manually invoke sleep via the apple/sleep menu command OR the power button on the G4 OR the power button on the ACD22. The power light on the ACD22's power button pulses evenly and softly ONLY when system sleep is manually invoked. There is no waking When automatic display sleep kicks in, making the screen dark, the steady power light on the display remains steady.
What I've done so far: reset PRAM, reset CUDA (power management) button, pulled video card and dusted/cleaned contacts before reseating.
There's probably nothing wrong with the ACD--It wakes up fine from manually invoked sleep when connected to the G5. Why won't it respond to the G4 from manually invoked sleep?

Sorry for my lack of clarity. I'm not sure how my wording got so jumbled. The display wakes from automatically invoked sleep (as set in Energy Saver), but will not wake from manually invoked sleep. One other possible clue is that when I invoke sleep manually, the ACD's activity LED does its soft "sleep" pulsing--When automatic sleep kicks in, there is no pulsing. The light just glows steadily as it does when the display is awake and being used normally.
I have started up in safe mode with only an Apple keyboard and Apple mouse plugged into the ACD itself. Nothing changes--it still won't wake up from manually induced sleep. The only other PCI card that I can see is one with 3 USB ports and one FireWire port. I assumed it came with this computer when the person who gave it to me bought it. Maybe not.
