Powerbook won't power on---please help!

Left Powerbook on overnight. This morning couldn't wake it up. Blue light at latch pulsing but nothing would wake it. Also noticed no color at battery charge input where it is usually green or orange, there was no color.
Finally took off the battery, left it off for the internal to run down, and when the pulsing light finally went off, I put the battery back. And now I still can't get it to power on.
I would appreciate any advice on what to do next.
Thanks!

Try a PMU reset:
1) If the computer is on, turn it off.
2) Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-Power on the keyboard. Do not press the fn (Function) key while using this combination of keystrokes.
3) Wait 5 seconds.
$) Press the Power button to restart the computer.

MacBook Pro - New out of Box won't power up - Please help me

I have reformatted this question several times.
Buy 15" rMBP from Apple Store. Take home. Sits sealed in box on shelf in closet. Open sealed box. Won't power up.
Take back. Genius bar has no idea. No signs of damage - water/fall/fire etc. Cord works. They send to Apple to fix since I have Apple Care (3 year)
Apple Cares says Water Damage. This is impossible. Had out of box 5 minutes. Genuis bar vetted that as possibility.
Apple sends pics from Depot of water logged rMBP. Go back to Apple Store. Genius Bar confirms that it wasn't like that, notes system.
Tech support says pay $1200 to fix, or they are sending back.
What can I do?

The 2.1.3 Software update won't work, the new version of iTunes won't download. Please help.

For several months now I have not been able to find a solution to either of these two problems. When I have the Apple Software Update program open and I click update, it loads for a second and then goes back to the usual page saying to update. It will not update. I have also tried, multiple times, to install the new current version of iTunes and that won't work either.

Did you try simply downloading the latest version of iTunes using the link below and then installing it on top of the older version?

HT201412 My iPod touch 4G won't charge. I charged it and when I took it off charge it was really hot but it showed it was fully charge then when I turn it on the battery was dead and know it won't charge. Please help thanks.

My iPod touch 4G will not charge. I charged it and when I got it off charge it was really hot but showed it was fully charge then when I turned it on again the battery was dead. Now it won't charge. Please help thanks!

Try the standard fixes to rule out a software problem:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod
if still problem that indicates a hardware problem and an appointment at the genius Bar of an Apple store is in order.
I suspect you have a hardware problem.

If I already purchased FaceTime for Mac and recently upgraded my HD. How can I retrieve that app again? I found it in my Time Machine back up, but the files won't work. Please help.

Nope. I do the same exact thing. If you have DVD's and blu-rays you can't download a free application called Handbrake. You can set it to Apple TV2 automatic format and they will come out as playable m4v's that can play I'm iTunes. All you have to do is turn on Home Sharing in both iTunes and your Apple RV and you'll be good to go!

Hi Emma,
Thank you for using Apple Support Communities.
I understand that your Thunderbolt display is just showing a black screen when you boot your computer. The following article should be of help in troubleshooting your display.

Satellite m300 won't boot! please help!

Hi,
I've got a bit of an issue here.. I have a Satellite m300.. a white one..
and it won't boot... I've had this very issue before but it turned out to be an external USB HDD that stopped it from booting up but now even with everything removed it still won't boot.
And it was fine until yesterday, it just gave up.. I am away from home for work so I have all the work stuff and unfortunately without my recovery cd, but my guess is that it won't even read it..
So this is what happens..
turn on..
all light come on.. including power and all the white lights around the keypad..
and then maybe 5 sedconds later caplock and numlock(?) green lights flash..
then it's a dead still.. no HDD activities or sound.. just dead quite..
the screen remains black blank through out..
it seems to get stuck here before reaching the post screen.
i thought the power button usually took more than just a push to turn off? it instantly swithces off with a single push of the power button..
I think this laptop is like on sleep or something and can't seem to wak up.. maybe?
And it has vista.
Please help.. I have some important work files I need to recover at least before formatting..
and that has to wait till I get home which won't be for a month or so..
which also lets me take it back for warranty as well..
any help appreciated!!!
cheers,
Min

Turn off all power incl. AC .

cmos .
Assemble PSU connectors ,only one DIMM module and graphics card and turn it on and se if you get a post .
Just removed all components. I reset the CMOS. I then reconnected the 20pin and 4pin, 1 stick ram, and the video card (no ide devices, no mouse, keyboard cd drives) and the monitor doesn't show up. I also tried another monitor so it isn't the monitor.
Could it have a bad AGP port?
Any other suggestions? I am thouroughly stumped. Also the power and reset buttons don't work no matter what configuaration I put the front panel connectors in. The Power LED is lit up and it doesn't work and the reset light is off and it doesn't work.
Also noticed one of my fans connected to one of the two other fan pins on the motherboard isn't working.
What a nightmare.

My powerbook will not start! please help! could be due to thermal paste?

I was recently reinstalling the keyboard within my 17' Al Powerbook. Afterwards, the computer booted fine and worked for maybe less than an hour, and then, on a reboot, shut down abruptly before OS X was finished loading. I restarted and was able to log in for several minutes. Now, upon opening the system, I noticed while replacing the RAM door I missed the slot it should fit into and it was put into place below this (which apparently is right over the CPU)...and when I pulled this part out there was some thermal paste along the edge. Looking into this area with a flashlight, the thermal paste seems sort of messy and some is in front of the chip rather than directly on it.
How likely is it that lack/messiness of paste is what is causing this? The battery fully charges within the system and the AC light is on. When I attempt to boot the machine, you can hear the HD, fans, and Superdrive spin for a second but you never see anything on screen.
Another thing that maybe the problem - when reinstalling the keyboard i forgot to replace the adhesive seperating the keyboard mount area and screws from the logic board - the first time the system shut down, I brushed my hand across the newly installed keyboard and the system shut right down. I'm not sure if this caused the overheating CPU to shut down, or if this caused the keyboard to contact with the logic board and I shorted it out and need a new one. I've since replaced this adhesive insulation plastic and the system still won't boot.
Any help would be appreciated. Please leave suggestions. I don't want to lose my mac

Updated Xperia Z on Pc companion, failed and now won't open! PLEASE HELP!

I flashed my phone months ago but now I just wanted to upgrade it to Lollipop or what ever is the latest update for my phone but the problem was during update, the PC companion suddenly stopped. Said it had errors, and would not go any further so I removed my phone from being connected to the PC and now it won't open. How can I make it work again? or at least can I still get the data inside? Please help this is a very heart breaking event. Important memories are inside my phone

Hi,
If I understand you correctly, the phone won't even power on now? No reaction while you hold the ON/OFF button? If that's the case, you will unfortunately not be able to backup any data.
With PC Companion you can perform a software repair. In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.
Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.

My G5 won't start up - Please help!

My Power Mac G5 won't start up! I turn it on and hear the start up chime, then the fan goes as usual and then it appears to be starting up - then it gets to initializing network connections (I think!) then the screen goes blue and it freezes! Does anybody have any idea why this is happening? Please help!

Hi viccilogan-
In that case, I offer a few more documents for your perusal and prior to actually being in front of the unit and able to troubleshoot.
The following may be helpful:

Intel iMac won't boot up, please help.

Yesterday I downloaded the iPhone 2.1 Software Update, I then lost two thirds of my contacts, I managed to get them back using the Sync System, I then downloaded the Security Update, which failed "Due to an error" and was "put in the Trash". My computer then crashed, I restarted it and now it won't boot up, it gets as far as the White Screen with the Apple Logo on it with the Spinning Bars "loading" icon underneath, it was like that for over an hour last night and I've tried again this morning and it's the same. has my hard drive gone or is there some less (I hope) final reason for this? Is there an equivalent to Windoze safe mode or similar?
Please help urgently.
Thank You

Try this qst... Safe Boot , (holding Shift key down at bootup), off the HD & use Disk Utility from there to Repair Permissions, reboot once more.
If that doesn't help, Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
If we still don't have it, try without a Tiger Disk, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: ** The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), off the HD & use Disk Utility from there to Repair Permissions, reboot once more.
