Powerbook will not run off of battery.

My 15in powerbook g4 (1.67 ghz) will not run off of its battery even though it is recognized and fully charged. Everything is fine when it is plugged in. The battery charges and everything else works until I unplug the computer. Then it just shuts off. I am not sure if this is related but recently it was waking from sleep by itself and even booting up by itself. I checked wake schedules, and nothing was set for automatic wake. I tried resetting the power management, but that did not work either. Now nothing is working and it won't even start without the power adapter.

Thanks for responding.
iStat says that my battery has gone through 392 charges. I'm surprised it even lasted this long. It seems to be working now, but it looks like it is losing its reliability and will probably completely stop functioning pretty soon. Money is tight right now so until that day I guess I will keep this one. Thanks.

Powerbook G4 Will not run off power adapter

Hi,
My powerbook G4 starts up and runs fine from the battery but will not run when the battery runs down even though the power adapter is plugged in.
The ASP shows that the adapter is plugged in but not charging.
I have tried three different power adapters, has anyone got any ideas?
Steve

Did yu notice this behaviour immediate after a software update? it appears you aren't the only one with charging issues. I don't know of any solution so you may want to search through these forums to see if anyone did find a fix for this problem.

Powerbook will not run unless plugged in

my powerbook g4 12" will only run off of the power adaptor. the battery seems okay. it reads as charged. and coconut battery shows a full charge (albeit with reduced capacity after 100+ cycles.) however it will not start up from the battery. and if it is running, and i unplug it at the unit, the computer dies instantly.
upon plugging it back in, it will start up fine. but my date and time settings are erased. and it runs fine on the power adaptor. but suddenly, this power issue happened, and it's like the battery is not even there.
so i bought a new aftermarket battery. everything seemed to go as normal. while doing the initial charge, the plug light on power adaptor glowed yellow. when i woke up the next morning, it was green. and after startup, the battery read as fully charged.
and then when i unplugged the power adaptor, bang! dead!
so, no change with a new battery.
the power does seem to make it to the battery, since the new battery did charge. but the unit will not operate off of a battery. even for 1 second.
i've done the pmu resets, and cussed some. neither helped.
help!

Welcome to the Apple discussions.
The reason the date resets to ancient times is due to all power being removed from the system. The 12" Powerbook doesn't have a battery to retain those settings like the 15" and 17" Powerbooks.
There are only 4 components in the electrical circuit: Power adapter, DC-in card, battery, and logic board. From the sounds of it, your power adapter is working, the DC-in card seems also to be working since power gets to the system to run it and the battery seems to charge, the battery, especially with a new one, we'd assume is good, and that, unfortunately, leaves the logic board. There isn't a test to see what might not be working in the power circuit, so you have to eliminate things to hone in on the issue.
You can't repair a logic board, so if you need your system to run on the battery, you'll need to replace the logic board. You can take it to an Apple store, and if the case isn't bent up, they can send it to the Apple Depot, which for me was in Houston, where they'll replace just about anything needed to make it almost new, for around $350. We had a Powerbook sent off for a new logic board, and they also replaced the battery (hint, if you take it to Apple to be sent to the Apple Depot, include your oldest, even if dead, battery). If the case is banged up, they charge more since they'll replace the case. If you want the Apple store to replace the logic board in the store, that runs about double sending it to the Apple Depot. Or if you're good inside a computer, you can buy a used board and change it yourself. Took about a week to get it back from the Apple Depot, and it comes with a 90 day warranty.

Powerbook won't run off of battery - requires PMU reset to power up with AC

Like everyone else posting here, my powerbook won't run from the battery. I have two batteries, one that came with the computer 3 - 4 years ago and a newer one that I purchased about 1 year ago. When I am plugged into AC using iStat Nano the newer battery shows cycles 173, health 89%. The older battery show cycles 0 and health 100% (go figure!). Both batteries just say 'calculating' on the tool bar battery meter. The light around the AC adapter plug always shows green as if the batteries are fully charged.
Here is where my post differs from the others. Once I shut down the computer I can't power it up again with reseting the PMU. I've tried reseting NVRAM and deleting and re-establishing the powermanagement plist as suggested elsewhere on this forum to no avail.
Is the PMU something that can be replaced? How is it related to DC-IN? I've read elsewhere here that is another problem that could cause these symptoms. Has anyone had these two components repaired and did it fix the problem? How much did it cost?
Thanks in advance for any information you can give men.

I had the same experience. I have 10.4.10 on the cloned drive but the battery is still not charging. I decided to take a closer look at the battery updater instructions and discovered that even though I am at 10.4.11 on my Powerbook the BatteryUpdater.bundle was at revision 1.1.3 and hadn't been updated since Jan 6, 2006. So I downloaded the BatteryUpdate that is posted at the top of this forum and installed it. It has made no difference in the operation of the computer. The AC adapter still isn't charging the battery although the green ring light is on which usually indicates the battery is charged. furthermore, when I go back and look at the date and version number on the BatteryUpdater.bundle they haven't changed. Who knows what the update actually changed! There is no mention of it running in the software update log. My system profiler says:
The battery is installed
Full charge Capacity 3890
Remaining Capacity 0
Cycle Count 173
AC adapter cannot charge battery: YES
By the way, my battery is a replacement battery.
I have just about exhausted all my option other than taking it into an Apple repair store and I'm not sure at this point I want to give Apple any more of my money. I am going to live with it the way it is for a while in the hopes that someone will post a fix for the problem. Good luck with your investigation. If you find out anything else please post it here as I will check back on a regular basis. If I find out anything else I will do the same. Nice working with you.

HP Pav. DV4-1428dx updated bios, now just flashing light will not run off ac

ran a few updates including bios, computer went dead with the ac plugged in, will not charge the battery any longer, when it goes dead and I leave it alone it will charge and start up and run off batter but just like right now with ac plugged in the lightning bolt is just flashing blue, i do not understand, ive read on the other sights of resetting the bios with USB drive, anyone got any ideas or assitance?

Dude, I have the same exact problem with mine. It's not a cheap fix either. It definitely is the motherboard.
I'm no expert, but I believe the problem is a dead capacitor on the motherboard preventing it to build up a charge.
I spoke with an HP rep, which told me it's $398 for them to fix.
I let them know that I didn't have another $400 to put into this laptop. So, they suggested I try reseating the motherboard. And also reseating the memory modules.
http://h10032.www1.hp.com/ctg/Manual/c01597750.pdf
That is a pdf of the laptop's manual. It'll help in reseating. Page ( 59 ) for the motherboard. Page ( 67 ) for the memory modules.
This hasn't helped at all with mine, but maybe it'll help with yours!

Powerbook will not charge my new battery

I have a 15" Powerbook 1.5 w/ a 1.5Ghz processor. I just bought a brand new battery and it will not charge. here are the facts:

- the battery will not charge, after a week the battery is down to 19%( I keep it pluged in all the time cause I do not want it to completely drain)
- I have reset the power manager unit
- I have past the hardware system test( the hardeware test disc that comes with the computer)

- I love Apple but they are really getting on my nerves, I have had top send back 2 ipods(one they actually had the balls to charge me for shipping) because of battery issues( the battery would only hold a charge for 20 minutes)
MESSAGE TO APPLE!!! either lower you price or build your products in the USA so we can get quality product. Having to send a computer to you for repair is not the answer, you owe your users more than that for the price you charge.
sincerly,

My wife bought me a new powerbook for christmas and I got it Jan 3rd 06.
Take it out of the box and set it up. Battery doesn't charge! won't Charge and apparently is a placebo! 2000.00 dollars, and counting. Imagine buying a new car without a battery under the hood! What the is going on??? I Go down to the apple retail store and they have NO 15" power books and no batteries because this is a big problem. They have been authorized to just swap out the computer, and or swap the battery. They are out of both till who knows when, (7 to 10 days ).! On the eve of the MAC WORLD CONFRENCE I am feeling sick about the whole IDEA that these power books were all sent out like this Apple should get them back before they are sent to consumers!! Apple and the reputation they have of being HIGH qaulity and RELIABLE is in trouble. How many class action law suites, POOR MERCHANDISE, ( I SENT BACK A NANO- CRACKED SCREEN and A PHOTO ipod that was purchased last Christmas- 400.00 dollar and a bum battery) Lets not forget the original ipod
LAW SUITE AND ALL, I had one sorry to admit. Qaulity is going down with Qaunity. I'm afraid to see what happens with the NEW intel Computers. It could just get worse. I just wanted to go wireless and I don't have a battery to
do that. So as I watch the mac confrence on my new 2000.00doller computer and am tethered to an Electical out let while getting stream from my new base station, I will certainly be thinking about how APPLE claims their stuff ALWAYS works better than a widows machine.... or does it really?

PB will not run on battery-RePost

Sorry, but I posted this under the battery and power section w/o a response.
A coworkers 12" PB will not run off the battery. As soon as she removes the power cord it shuts off. New working battery was purchased and used.
Any ideas?
Thanks

There are 3 components to the charging circuit: The power adapter, the battery, and the logic board (and within that the dc-in card).
When the battery is installed, what does it say about it in the system profiler (click blue apple, about this mac, more info, power)? What's the fully charged vs current capacity? Even though it's new, how many cycles are on the battery? When you push the button on the battery, how many lights light up?
You might have the person try resetting the power management unit (PMU), following directions at http://docs.info.apple.com/article.html?artnum=14449
If you know for a fact the power adapter is working, and that the battery is fully charged, then it's either a dc-in card problem (this is the card which has the plug the power adapter plugs into) or a logic board issue.

PB will not run on battery alone

Hello, a coworkers 12" PB will not run off the battery. As soon as she removes the power cord it shuts off. Any ideas? She is kind of tight on money and i am new to Mac.
Thanks

Battery status can be checked this way:
Click on the Apple logo, select "About this Mac", click on "More information" button and have a look at the power information shown on the newly opened window (within "Hardware" section).
Maybe you can post the battery conditions listed there for further clarification.
As stated by Malicious DreD, batteries are losing capacity over time and the PB will simply shut down to prevent data loss when battery is empty.

Battery showing 100% charge, but not running off battery

I have an Hp Pavilion 10 Touchsmart that shows a 100% battery charge, but will not run off the battery when I unplug the AC adaptor. I have tried calibrating the battery which went okay. I have tried uninstalling the microsoft driver for the battery and reinstalling it and it did not fix the problem.I have also checked the "Battery Report" using the cmd prompt. The battery report showed everything was charging good with the battery on the laptop for many days.I checked the "Energy Report" using the cmd prompt. The energy report had some warnings, but it was all relating to energy use.I have owned this little computer for less than a year and it should not be giving me this much trouble. At this point, I think I have done everything I can do on my end especially since I cannot remove the battery without disassembling the laptop. I do not think it is a bad battery unless it is defective because the computer sees very little use and it is less than a year old so I am thinking a software problem. Any additional suggestions?

It is my understanding Hp warranty is only 90 days which means it is not under warranty. I have owned the laptop for less than a year with it shipped by Hp on "Thur 9/18/2014 5:15 pm". I orginally thought it was not under warranty, but I just tried a Hp warranty status site and it said "2015-10-23" was the warranty expire date.

I1300 1171-9XU will not boot off battery

I'm having a weird problem with my usually reliable i1300. It will not run off any battery at all. I have 2 fairly new replacement batteries that have worked really well in this laptop. Here are the symptoms.
Seems to draw juice while the unit is off, battery discharge level is down after it's been off a couple of days
Will charge the batteries back up to 100%
Laptop immediately shut off when power is pulled.
Will not boot off the battery at all.
The IBM notebook utility will not refresh the batteries
When the power cable is pulled and you try to start it you hear this faint pulsating clicking noise. The batteries work in another i1300 laptop normally and the notebook utility works fine.
I have some spare parts for the I1300 but I'm not sure what to replace at this moment.
Thanks for any help,

Thanks for the reply,
I started with the easy fixes first, changed the sata cables, and tried different power supply connectors. Both tests had same results, still boots up on 2nd try. I did not know how soon the problem would re-occur after it has been shut down, my shortest time so far is 25 minutes.

Why only one RAID channel is enabled? Array can't be detected in that way...
Well right now, it is not even set up that way, in my #6 problem solving, it was suggested that I turn the Raid Mode off and try [IDE] to see if that made a difference,"because I don't need Raid enabled for the hardware raid". It did not, it only booted to the "Reboot and select proper boot device or insert boot media in selected boot device and press a key" window about 60 seconds faster. It is currently set up in this way.
This is how it looks in my On-Chip ATA Devices
How do I check this?

Does the problem persist when you use Silicon RAID instead Nvidia RAID?
I am still working on getting the seagate diagnostics to work, I am getting an error message before I can even test them.
I do have another question. Why is my HP Printer showing up in the Hard drive test, and also why is it showing up in my boot sequence, is this normal?
And speaking of boot sequences I got in there again just now and saw 2 [USB:HP Photosm]
Thanks again, still working on testing hard drives.

Macbook Pro will not power on without battery installed

Hi there,
I have a Macbook Pro A1226 that fails to power on without a battery installed.
i.e. will not run off AC power on its own. I have tried 2 other power adapters, no change. All 3 adapters are outputting the correct voltage without fluctuations.
But, if I am in OSX with a battery plugged in, shutdown the laptop, remove the battery while AC is still plugged in, it will power back on without any issues. But as soon as I remove the battery, it will not power back on using just AC.
Is this an I/O board issue, or a mainboard?
I have power drained the unit and reset the parameter ram.
Thanks

Any update on this? This is the same thing that's going on with my laptop right now. I was at the Genius Bar and they said they can send it in for repair. Takes 7-9 days and costs a minimum of $310. At the time I was there, my computer wouldn't start up at all, because the battery had drained to less than 20%. It didn't even start with just the power cord (no battery in). The "genius" finally got it to work by doing a PRAM and SMC reset. Got home and was able to recharge my battery to 100%. Used my computer for 2 days before I dared to take it off the power supply. Lo and behold, as soon as I take it off the power cord, then re-connect it, it shows "Not Charging". I tried to do SMC again, but no luck. Keeps saying "not charging". Even tried with a brand new battery. Do I have to get the I/O board thingy replaced?

My Powerbook will not power up, but I can hear the fan running...

Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
Any answers to this yet? I think I'll call on this and report any success to this discussion.

Battery shows as having charge in System Profiler yet will not run from bat

My MacBook is about a year and half old. My battery just started doing this a few days ago. It shows as not charging. Checking the battery shows that it has 85% power left (this was 86% the day it started). The magsafe connector stays green. The MacBook will not run without the power connected.
I am not sure if this is an issue with the battery, the batteries connector, or with my MacBook. I'm pretty tight fro cash right now and need my MacBook working. I don't have money to throw at parts I don't need. If anyone has experienced this issue before and has any insight please let me know. I'm a starving web programmer and I need to be able to bring my MacBook with me to meet with clients.
Thanks,
Steven

Do you think it is software. It will not even boot when the power is not connected. I was thinking it was a problems with ACPI in the EFI BIOS. The strange thing is just a moment ago the magsafe went orange and the power states calculating. This is the first time I've seen the magsafe orange since this started four days ago. I came back to this thread to update it with this little tidbit and saw your reply.
