Powerbook wont turn on.

I got a powerbook g4 from a friend. Said I could keep it because it doesnt turn on anylonger. I've been trying to diagnose the problem but pretty much cant do that because i cant even get the thing to turn on.
When i plug the charger into the laptop i get the green 'halo' from the charger, also the battery indicator is showing it as full. I also tried taking out the battery and keeping the charger plugged in. Hoping that it might turn on. But no luck with that either.
Does anyone have other suggestions. I was thinking that the system board might be 'done'. I just wanted to find out from other people before I invest money into this laptop. Thank you.

Hi again,
Try taking a look at this article:
Troubleshooting: My computer won't turn on
Check each step to see if there's something we might be overlooking. Of particular note will probably be PRAM or PMU reset.
Please post back with any results.

PowerBook wont turn on unless I turn it upside down!!!

Ahhhh ok this is annoying!! My powerbook wont work unless I turn it upside down!! When it is right side up..I turn it on and it just comes up with a blank screen. However, if I turn it upside down it works just fine! Once its working ok upside down, I turn it right side up again and it freezes!!!! Any suggestions?? You think something might be loose inside?

I recently had the same problem. It turned out to be my hard drive was in the process of going down the tubes. It had also started making some strange noises. I would definitely back everything up and get it checked out.

PB G4 1.67 wont turn on.

I have a g4 powerbook 1.67 that was dropped from about 6-10 inches onto the corner where the battery installs. Screen looks fine, corner of the computer is slightly dented, and the computer wont turn on. i have opened it up and checked all the conections and I get nothing. The battery won't charge either. Is it possible I killed the power board? its on the same side as the dent. Any other suggestions I can try? Any help would be great.

Afternoon,
I left my house yesterday and came back 3 hrs later and my computer was dead... I have no clue what happened. I have left all out for a hour or so in addition to doing the plug in / no battery w the 5 second hold.. HELP...
I took it to the genius bar and he said I had discharged a shock while replacing my hhd or my super drive( but I usually make sure I am clean / dry and i do all surgeries on my desk blotter) so his conclusion was the logic board....
any other short cuts / experiments I can do to try to power it up. I am using a friends dell...ugh to figure all out. Thank you all for your prompt help.

IPodTouch 3g:ipod wont turn on

my ipod touch 3g wont turn on and its stuck backing up on my mac

Try restoring with the new 2006-01-10 iPod software update. There's been a bug associated with bookmarkable AAC files (including bookmarking audiobooks)ever since the 2005-06-26 iPod update (the one that introduced support for podcasting and making podcasts subscribed to through the iTunes Music Store bookmarkable). While not all color and photo iPods have been affected by this, a number of people have seen freezeups. (See the "Having to reset iPod a lot" thread http://discussions.apple.com/message.jspa?messageID=1159461#1159461 ) Some people have dealt with this by reverting to earlier software updates (from their installation CDs) to recover stability.
The new iPod software update is the first one with corrections for 4G models since 2005-06-26. It fixed at least one other thing that got broken with that release (dynamically updating smart playlists); it may have fixed this problem.
The general solution is to do a restore. I'd advise trying the restore with the latest software update, though.

Wont turn off or restart

my friend just called me in a panic saying herm power book went to sleep when she was at school and when she came home it wont turn on or restart even when you take the battery out.

Well, if there is no power than how is it going to start? With the battery in & the power cable plugged in, try to turn it on. When the powerbook goes to sleep and the battery runs out, it'll still be on but you won't be able to wake the computer up because there just isn't enough power. But, when this happens, you can plug in the power cord then press the power button in order to wake it up. If what I said doesn't work, then there is probably a bigger issue.

Battery wont charge and isight camera wont turn on-macbook, battery wont charge and isight camera wont turn on-macbook

i bought a macbook from a guy and when i started it up... surprise it wont turn on if its not connected because the battery is not being detected.... then what i checked first was photobooth surprise the isight camera is not working... i searched in internet about smc but i do not understand it.... is there a way to recover it using the cd?

Try resetting the PMU - Resetting MacBook and MacBook Pro System Management Controller (SMC). If you have no success then you'll need to take it in for service or replace the AC adaptor if it's gone bad.

As far as trying to power up your device, make sure it has a good charge and then hold the button on the top of the phone and the home button on the faceplate together until the apple appears on the screen.

Try to backup and restore you device in itunes...restoring the device is like removing the iOS software off the device and re-add in a newer software, after you have restore you device, MAKE SURE YOU SET UP YOUR DEVICE LIKE A NEW DEVICE, DONT NOT RESTORE FROM BACKUP!!... give the device a chance to use the newer software and see if the issue still persisting, if the issue still on going then its would be a hardware issue.
Call Apple Care and see if your device is still under warranty to get it replace

Hello ole-gunnar,
Thanks for using Apple Support Communities.
If your iPhone is unresponsive after updating your iOS version, then I'd like you to please follow the troubleshooting below.
If you see a black screen
You might need to charge your device before it can turn on. Plug in your device and let it charge for at least 10 minutes (20 minutes for iPad), then try turning it on.
You should see a battery icon while your device is charging. If you continue to see a black screen, reset your device. If your device doesn't respond when you press buttons
Your device might not return to the Home screen when you press the Home button, wake from sleep when you press the Sleep/Wake button, slide to unlock or power off, or it might appear frozen. Try these steps:
Restart your device.
If it still doesn't respond, or if it doesn't turn back on, reset your device.
If your device gets stuck during startup
When starting up, you might see the Apple logo or a red or blue screen for a long time, or your device might restart again. Try these steps:
Make sure that you have iTunes 12 or later on your computer.
Put your device in recovery mode.
When you get the option to restore or update, select Update. This will reinstall iOS without erasing your data.
Get more help
If you still need help after trying the steps above, contact Apple Support.
