Massive Power Failure Powerbook G4 15"
Hello,
I was given a Powerbook G4 (15" 1.67ghz running on 10.4.11) by a friend who had not used it for about 6 months. The battery was not taken out during those 6 months so I expected trouble there. However, after charging it while it was switched off, it booted perfectly and ran smoothly. The problems started when I plugged in the ac adapter to charge it while running. As soon as it connected, it crashed; blue stripes and all. I have tried to charge it while it is turned on many times but it almost always crashes imediatly and sometimes stays on for a few seconds (and shows the batter connected icon) before crashes the excact same way. Also, although it charges the battery when switched-off and boots perfectly on the battery, once it is plugged in it won't come to live. It gives a little sigh and sometimes the fan goes on, but then goes silent. So I took out the battery and booted it on the ac adapter alone. It booted and worked for about an hour, and then crashed the same way. After that happened it also didn't boot from just the ac adaptor anymore.
I have tried the PMU and PRAM things, but they didn't do anything.
The adapter plug and the jack seem to be fine, they're not loose at all.
The battery specs are:
Full Charge 3637
Amperage -1488
Voltage 11387
Cycle Count 387
I guess the battery can be replaced but I wonder if that would solve the problem, knowing that it works fine on just the battery, but that it fails to boot while plugged in, or plugged in without battery. Anyone any ideas? Should I risk buying a new battery??
Your help is much appreciated!
PowerBook battery calibration - reserve battery power - Dr. Battery
Hello,
I have a new replacement battery from Dr. Battery for my 12" PowerBook G4.
I decided to calibrate the battery as described by Apple. That is, from a full charge, keep working on battery power and keep doing so when it gets to near zero when you see the 'plug in to power or computer will go to sleep' message. The reserve battery power will kick in and the computer will sleep after a few minutes; you'll see the twinkling light on the latch come on. Shortly after that, charge the battery to full.
This is how my original Apple batteries used to work, always. But the Dr. Battery battery simply crashed or shut down my PowerBook soon after the 'plug in to power or computer will go to sleep' -- the laptop couldn't/didn't go to sleep. What's more, when I restarted it, the date had reset to 1-1-1971. Does this mean that a Dr. Battery battery cannot store reserve battery power? Is there some way to fix it?
The strange thing is that the first time I calibrated in this way with this new battery in the first week of January, it *did* work like it should.
Thanks for any info.

MacBook Pro 2012 suddenly won't power up
My mid 2012 MacBook Pro just developed a strange power problem, won't power up at all. None of TS1365 above helps. The magsafe adaptor works fine on another Macbook. On the new MBP the green light slowly dims, and there are no lights showing at all for the battery when its button is depressed. Is this an Apple Store visit required?
My MagSafe Charger / Power Supply is not working
I am using mid 2009 13" MacBook Pro with 85W MagSafe . My operating system is Lion 10.7.4.
I heard a "click" coming from the direction of where my charger and just before and now its not working.
- The light is not coming on the charger itself
- No power is shown be coming into the computer on the Desktop toolbar either, nor does my computer that there's a charger plugged in.
- I have tried the charger in a number of the different sockets around the apartment and still no joy
- The transformer "block" is cold
Could this be a s simple as a blown fuse in the plug or something else altogether?
I need to fix this asap. No power = no computer. All help much appreciated.
power cable issues, no light, unless unplug, etc
Hello All-
I have a macbook pro with the "L" style magsafe connector. I am running 10.7.5 OS with a 2.4 GHz Intel Core i5 processor. I am up to date with all software updates. The chord and computer connections are clean, intact and unobstructed.
I've noticed that my power cord light will be off (and not charging the computer) and if i unplug it from the computer and replug it in, i get nothing. If i unplug from the wall and plug back into the same outlet, then you get nothing. if you unplug from the outlet and plug into a different outlet then the cord illuminates and starts charging the computer. doesn't matter if the outlets are in my kitchen, at work, etc. same phenomenom. i wonder if it has something to do with heat from plug assembly. By that once it heats up, then you get a bad connection, and plugging it into an unused outlet will work.
Anyone else had this issue? it's a pain to be crunching large datasets and come back to the computer drained of power and off because the cord is no longer giving power.
Thanks in advance-
Todd
power issue on macbook pro
good morning,
I have a MacBook Pro 13" laptop, latrst generation, purchased new 12/12. All has been well until last night when I noted that the sleep light was off and there was only a weak flutter on the mag safe power connector. I tried to power up the laptop from the power button with negative results. I then unplugged the power adapter both from the computer and from the power source. The power strip is fully functional and supplying power to a lamp and my IPhone charger. I tried moving to another live outlet, re-connected and got the same weak flutter on the magsafe charging head. I then tried to see hoe much power i had on my battery. Zero, zip, nada...the battery is COMPLETELY drained. I cannot even get the computer to power up to do a SMC reset.
The computer is normally left connected to the power adapter on my desk, and will normally show 99-100% charge when I wake it. I have no idea what happened, if anything, or how to restart. Any suggestions?
why is my mac using power when its sleeping?
When my Mac is closed and in my bag it is still using battery about 6% every 2 hours while its asleep.
How do I stop it from doing this or at least slow it down because it always seems to be on charge!

Battery life endurance longer with plugged power cable?
Heyho,
Concerning the life endurance of my battery, should I constantly let the power cable being plugged to my Macbook or should I constantly load and unload the battery?
Thanks for potential help.
MacBook Air unable to function independent of power adapter
it says the battery is not charging on my MacBook Air 11'. however once it's connected to the charger it works fine but once I disconnect it it turns off automatically. Also no light appears on the led on the charger when it's connected. I've tried to reset the SMC, but not sure if I did it right because I had to do it disconnected to the charger because when I connect it it turns on automatically. I've also tried plugging it into various different plugs in the house. I would be very grateful if anyone has any suggestions!

Do I have to use the Apple Power Adapter specifically to charge my iPod nano without using my laptop?
CAN I CHARGE MY IPOD NANO WITHOUT USING THE APPLE POWER ADAPTER? Can I use any of my many usb wall charging adapters instead?
