my computer won't turn on

Hi, and welcome to Apple Discussions.

Check out Apple's Knowledge Base article on troubleshooting portables that won't turn on or start up:

http://docs.info.apple.com/article.html?artnum=50959

Ok first have you been messing around inside the computer? Check your battery is there anything wrong with that? If not then it's probally the Logic Board. Logic board helps the computer startup if thats damaged then yo wont beable to turn it on.

I was using my computer last night and it was working
fine then i shut it down and tried to start it back
up and it wouldnt turn on...not even a
sound....anyone have any suggestions?

ME too! Any advice / resolution to this problem? I'm looking to move to a MacBook anyway, but how will I recover the HDD in the event that I can't restart the iBook?

just seconds ago, my laptop was working fine. then it froze. i manually restarted it...but it won't turn back on. i just had the logic board replaced about 2 weeks ago, but it wasn't showing signs of giving way.. i've never had this happen before. i can't get it to turn on at all now. suggestions?

Did you have the logic board replaced under the iBook Logic Board Repair Extension Program? If so, you may have received a bad logic board. The repair is warranted for 90 days. Give Apple a call.

This sounds like it could be the logic board. If it is, and you have access to another Mac with FireWire, you may be able to get the iBook to remain responsive in FireWire Target Disk Mode long enough so you can retrieve your data by this method:

If the iBook is on, shut it down and wait 30 seconds (or longer). Pick it up in your left palm to the left of the trackpad and squeeze the case there between your palm and left thumb as you push the power button and key combination to start up in FireWire Target Disk Mode. Do not let up the pressure on the case. Continue applying this pressure as you save your data to the other Mac. If you let up and the iBook dies or freezes, you will have to start over, allowing it to rest several hours or overnight before beginning again.

If you determine that it is the logic board, you can follow the instructions elsewhere in this thread to explore repair options under the iBook Logic Board Repair Extension Program.

Let us know how things go.

P.S. to Apple Discussions, Karl.

RE: hagedorns3::computer won't turn on..

Craig here.. I just experienced the same situation. I'm on a family vacation.. Have work to do.. Was using the ibook and after a shut down.. Couldn't revive it the following morning. I've gone through all the PMU reset steps from Apple support article.. Nothing.. Battery shows strong 4 green lights. AC power shows strong green. Logic board was replaced once before. Similar issue. Dejavu? Trouble in Paradise..

Hi, Craig. Welcome to Apple Discussions.

AC power shows strong green.

All this means is that it isn't charging. When things are working right, it isn't charging because the battery has a full charge (and, with the four green lights, it sounds like this is probably the case with yours, currently).

If the logic board was replaced less than 90 days ago, it will be under a repair warranty.

If you've truly gone through Apple's Knowledge Base article on troubleshooting portables that won't turn on or start up and done everything suggested there, you are probably going to have to take the final step and look for a service provider.

Good luck.

Hi

I have a similar problem. My ibook G3 (last one before the G4) won't turn on. All was fine night before, restart next day and no response. Tried all the advice for reseting etc. It had a replacement logic board last year. Can you get a second replacement logic board from apple if this is the problem?

Hi, Erin. Welcome to Apple Discussions.

Can you get a second replacement logic board from apple if this is the problem?

Yes, you should be able to have it replaced again as long as it was originally purchased less than three years ago. (You do NOT have to be the original owner.) Mine has been back three times for a logic board replacement.

Good luck.

Can I have my logicboard replaced by Apple even if it won't start at all? I remember reading somewhere that they won't take if it it won't boot???

Did it have the symptoms listed on the iBook Logic Board Repair Extension Program FAQ page before it quit working entirely?

If so, it may qualify for the program.

Have you tried restarting it while squeezing the case to the left of the trackpad? Sometimes it will start up when you squeeze it there if it is the logic board at fault.

Yep this is what I am discovering. I had my ibook checked - diagnosis is that it is a logic board problem which needs replacing. My computer is covered by the scheme; the part is covered by the scheme; BUT because it isn't a listed problem Apple won't replace it for free. This seems rediculous to me. Obviously they need to change the list to incorporate all logic board faults. Mine was only replaced 10 months ago and it's given up the ghost already. It makes no economic sense for me to pay for this - it's half the price of a new computer.If there are any helpful suggestions out there I would be pleased to hear....

Obviously they need to change the list to incorporate all logic board faults.

No, Erin. The only logic board faults that occur in sufficient number to warrant such a program is a specific fault. However, since yours initially had that specific fault and was replaced with a logic board that failed in this new way, you may want to call Apple again. Ask for Customer Relations (NOT Customer Service), and plead your case that if the original logic board had not failed with the covered fault, you would not now have this logic board that has failed in this different way.

Good luck.
