Powerbook G4 won't charge battery or run with power adapter plugged in.

My Titanium Powerbook G4 will not charge the battery or run with the power adapter plugged in. When plugged in the power adapter doesn't change to amber showing its charging. Instead it has a green light that flashes off and on. I thought it was a defective power adapter but when its plugged in to another powerbook its seems to be working properly. I reset the PMU but that didn't help. I have been unable to find anything that would tell me what a flashing green means.
Powerbook Titanium G4 Mac OS X (10.3.9)

Hi, Marshall. With no power being supplied to the Mac for several months, not only has your main battery gone flat (and may never again be able to take a charge), but your internal backup battery has also gone flat. A Tibook with a dead backup battery generally will not start up at all, even with AC power connected.
Try this: remove the main battery and leave the AC power adapter connected overnight in an attempt to recharge the backup battery. If the Powerbook won't start in the morning under AC power, the backup battery is shot, has lost the ability to be charged, and must be replaced.
If the PB starts up in the morning on AC power, set the date and time correctly, shut the computer down, insert the main battery, and allow 48 hours with AC power connected in an attempt to charge the main battery. Then disconnect the AC adapter and try to start up under battery power. If that doesn't work, and no lights or only one flashing light appear when you press the power-indicator button on the battery, you'll have to replace the main battery.

Battery won't charge but will run on power adapter

My macbook pro is less than 1 month old and it won't charge when plugged in but will run on the power adapter. The problem started a few days ago and I have tried many different outlets.

Reset SMC. http://support.apple.com/kb/HT3964
Choose the method for:
"Resetting SMC on portables with a battery you should not remove on your own".
If resetting SMC does not help, you have to take the MBP to the Apple store to have it checked.
Best.

PowerBook G4 won't charge battery

Hi all
My last-generation PowerBook G4 won't charge its battery. It will run fine off of its power adapter, but it won't attempt to charge the battery, which the system states as having a 0% charge.
I don't think it's the battery; the last time I ran the PowerBook off the battery a few weeks ago, the battery was still holding a charge for over an hour. The battery has been used for 179 cycles; iStat Pro describes the battery health as being 87% (this may be wrong, of course, since it is also describing the battery as charged). The PowerBook just isn't trying to push a charge to the battery.
I only use my PowerBook every so often; usually it spends its time off, and not plugged in. Last time I found the battery had completely drained, to the extent that the clock has lost its time, so I put it on to charge, and left it. The next time I tried to use it was when I realised it wasn't charging. The notebook hasn't taken a knock that I'm aware of (at least, a new one), so I'm not sure why this is suddenly happening.
Any help or ideas would be appreciated. I don't want to waste time and money dropping £100 on a new battery if the issue lies with the PowerBook itself.
Cheers!
(PowerBook specs: 1.67GHz PB G4, 2GB RAM, Mac OS X 10.4.11)

Well, I left the laptop unplugged (and with the battery out - not that it would've made a lot of difference, since it doesn't currently have enough juice to highlight ANY of the charge indicator LEDs) for and hour and a half, booted the machine, and the clock kept its time. I'm not sure what that proves at this point, if anything.
As for the charging circuit, well the computer still isn't charging the battery (the main battery, not the PRAM battery). From your suggestions, the socket seems fine, maybe a touch lose, but then it's not exactly new, and my old adapter used to be worse. The only similar charger I have to hand is an adapter from an iBook that's about a year older, so I'm not sure the wattage will match. That said, surely since the adapter is actually powering the computer, it won't be the adaptor or the DC-in board, since I assume they are also responsible for getting the power to the computer itself?
I assume (and I am assuming here) that it is either a knackered battery or logic board. This machine has already had its logic board and DC-in board replaced, for what its worth, back when it was only 5 weeks old (probably irrelevant).
Thanks for your help thus far!

Macbook won't sleep with power adapter plugged in

Hi,
My Macbook has stopped going to sleep if the power adapter is plugged in.
I have the power adapter energy setting to sleep after 30 minutes. When I got the Macbook (about a month ago) the thing would sleep until I pressed the spacebar.
Now, the screen blanks but otherwise the Mac remains awake.
If I close the lid the Mac immediately goes to sleep.
I have reset the SMU but this didn't fix the problem. I also checked disk permissions and verified the disk in Disk Utility - all good.
Suggestions?
Thanks,
John

my MacBook has also stopped going to sleep with the power adapter plugged in or when using battery power, unless I close the lid. Did you ever figure out the problem? Did you try calling Apple Care?
thanks,
Liz

Battery won't charge, but will run on the adapter power.

I've had my MBP for about a month now. The problem I've had for the past few days is that the computer will work completely fine when it's plugged in, however the battery won't charge. Once the adapter gets removed, I get the popup that tells me that I'm on reserve battery power. When I click on the battery icon at the top right of the screen, it tells me that the battery is not charging, but it also tells me that the power source is the power adapter.

You need to take it to an Apple store or AASP and have them run a diagnostic on your battery and power adapter. If either is bad they will replace them, and if it's not the battery or power adapter, then it's probably the logic board.

My battery won't charge, but the computer and power adapter show all signs it should be. Help?

Last night, when both my power adapter and laptop were showing signs that I was fully charged, my computer suddenly died. I restarted my computer, and it said my battery was at 0%. That night, I fiddled around until my power adapter said it was charging and then went to sleep. This morning I come back, and my battery is at 0% still, but both charger and laptop show signs that it's charging (brighter screen, LED is orange, lightning on the battery icon). Does anyone know what's going on?
I have a basic MacBook with the magnetic charger, and it's a few years old.

Hopefully some of this helps. Could be another issue behind the symptoms.

IBk G4 won't sleep automatically while running on power adapter

I have suddenly developed this odd issue. My iBook sleeps fine when I shut the lid, both when running on adapter and on battery. And when I go up to the menu & tell it to sleep it will sleep (for both) as well. It just won't go to sleep on it's own while running off the adapter (I've tested it, and it does sleep on it's own when running on battery). I've repaired permissions & restarted, repairing again but this doesn't seem to help. I saw someone mention looking in the activity manager area for printer mentions but I don't think this would be the problem since it is fine off the battery? Not a big deal really, but wondering what would cause this! Thx for any ideas!

I have repaired permissions & restarted a few times, without any change.
I just looked at my activity monitor. There are many things listed ... this is not something I'm familiar with looking at! Some of the list I know right away what things are, and some I have no idea! But, if it sleeps correctly when running on battery but not AC, would it have to do what is listed on Activity Monitor? My guess is perhaps not? Maybe I need to zap the RRAM? But like the poster above me said about his, it's an old iBook and not really a big deal, I can tell it to sleep!

My iPad won't charge, battery icon comes on when i plug it in but it won't charge any further

I have been trying everything to get my iPad to charge. Its an ipad2 wifi. its been off for probably two weeks if not more, just haven't had the desire to use it as i have an iPhone a macbook air and a new iPad mini so it kinda just sat there....now I'm wondering if its just gone kaput! Ive tried various cords and outlets. switched the cord... and still nothing. I grid doing a hard reset (home button and power button at the same time) and that didn't work either it just flawed the battery icon at me. when i unplug the iPad it says i need to charge it.... and well I have been trying.... what should i do!!??

Hey misskyla88,
Thanks for the question. If I understand correctly, the iPad will not charge. It looks like you have already done some troubleshooting. I would recommend that you read this article, it may be able to help the issue.

Ipod Mini only runs with power adapter

Like the title says, I cannot figure this problem out..
The battery has been replaced and is brand new. Yet the ipod mini 2nd gen will only play songs and turn on when its connected to a permanent power source. For ex, the wall charger or the car. If it is disconected, it will turn off and there is no way to turn it back on unless its plugged back in.
Please help!
Dell Windows XP Pro

Try to reset it.
Press and hold the MENU and CENTER buttons - at the same time - until you see the Apple logo. This should take about 6 seconds. Also, you want to do this procedure while your iPod is connected to your computer. Ipods are supposed to work with USB port cable and AC Adapters, not only car chargers.
If this doesn't work, then try to update it using iPod Updater software. Open iPod Update, plug in your iPod to your computer and wait until the software recognizes it. Once it does, you should be able to click on the "Update" button. If you can't, click "Restore"

Won't charge, battery good

My Powerbook will not charge the battery while the computer is in use. If I put the Powerbook in sleep mode, or turn it off, then it WILL charge the battery, but slowly.
It's not a bad battery, because if I take the battery to a friend's powerbook and charge it there, it works, the other powerbook charges it normally. If I disconnect AC, my computer will run off the charged battery.
If I let it charge overnight, then run it off AC, then I can use the Powerbook all day, and it works, but the battery very slowly discharges. It will not charge the battery, while in use.
I thought it might be the DC in board, so I replaced that, but I still have the same problem.
I've tried a different AC adaptor, and get the same problem.
Has anyone see this before? Do you have any ideas on what this could be, or how to fix it? I assume I could replace the logic board (I'm guessing is the problem) but I'm more likely to live with it, and just make sure I charge it every night.
It's G4 Powerbook, Aluminum, 1.5 Ghz
Thank you,
Bill

There are only 4 components in the charging circuit ... the power adapter, the DC-in card, the battery, and logic board. You've indicated confidence in 3 of the 4, and from how you've tested that sounds good. So I'd agree your logic board is acting up. Cheapest fix, beyond living with it, may be to replace the board yourself, or send it to the Apple depot thru your local Apple store, around $325 if everything else is in reasonable shape.

PowerBook 5300 won't charge

my old PowerBook 5300 won't charge the other day I got it to boot by wiggling the cable but if it moves a little bit it doesn't charge anymore. The battery still holds a charge but once it's dead it's almost impossible to get it charged.

This is not an unusual problem with notebook computers. The solder joints at the DC-in jack work loose. Anyone with basic soldering skills could resolder the pins. You can find disassembly guides, for example, at ifixit.com. Repair instructions regarding this very issue on the PowerBook 5300 can also be found on the Internet.

HT2037 icon reads "battery not charging" with power adapter lit "green". Do I replace battery or power adapter?

Hp pavillion dv9700 won't start with Ac adapter plugged in

Dear all,
I have a 3 year old hp pavillion dv9700. The problem is that the computer won't turn on when i remove the batteries and leave the Ac adapter plugged in. The led that indicates that the adapter is plugged in is on, so that means that the adapter is working fine. But to be sure, I used another Ac adapter from another dv9700.
The next thought I had that the problem might be the Ac jacket( that is connected to the motherboard ). So I dismantled 2 dv9700 laptops (one is mine, the otherone from a friend, which is by the way working fine), and toke out the Ac jacket from the laptop that was working oke and replaced it with mine(whIch wasn't booting with the Ac adapter). And still the same problem. So now I am able to say that there is something wrong with thE motherboard.
When ever I plug in a battery that is not empty, the laptop starts up normally. The other thing that noticed is that whenever I plug in the battery the led of the Ac jacket turns on (not full bright, but somewhat dimmed). This doesn't happen normally. That means that there is somewhere a short circuit on the motherboard.
I have looked all over the internet, but wasn't able to find someone who had the same problem as me, or a solution for it.
Ps. It has nothing to do with the video card, because if that was the case, it wouldn't even start with the batteries.
Already thanks, kdeo2k

T.C., Endless Preparing Backup on Battery, Works Fine on Power Adapter?

When my computer performs a backup while I'm using the battery, it just says Preparing Backup and doesn't progress. On the other hand when my computer performs a backup with the power adapter plugged into my computer, the backup works fine. I can't alway carry my charge around with me, so is there any way that I could get my Time Capsule to backup while I'm using the battery?

Welcome to the discussions!
"so is there any way that I could get my Time Capsule to backup while I'm using the battery?"
Can you check a setting by clicking on the clock shaped Time Machine icon at the top of your screen and selecting Open Time Machine Preferences?
Make sure that there is a check mark next to "backup while on battery power".
Not sure if this is causing your issue or not, but good idea to check this if you haven't already done so.

MBP discharges battery even while power adapter plugged in.

Just recently, my MBP started discharging its battery even while the power adapter was plugged in. Eventually, it goes dead and shuts itself off, then starts recharging. I've turned off bluetooth and airport, going to a wired/plug in mouse, but that doesn't stop it, nor does changing to "better energy savings" while on Power Adapter. While it is going down, time of course remains "Calculating until full" -- I've checked the pins, and even spent 3 hours yesterday driving to the apple store, waiting, getting a new batter from the genius, and driving back home. Then it happened again with the new battery this morning, after it was fully charged last night.
Any suggestions? thoughts?

Have the MBP repaired via AppleCare. Just let them know what it's doing. I'd guess at a fault in the charging circuit, but this is obviously not normal behaviour!
