PB 1400cs won't run on battery power

I've got a 1400cs, purchased second-hand, and it seems to have a problem running on batteries. Even with a new battery, it doesn't want to run on battery power. `Runs fine on AC power, though!
What could cause this? What are my options for inexpensive repair on this problem?

Keith,
I also have a 1400 with the original battery which will not even run the 'book for a second when I unplug the power adapter, but I don't use the 'book anymore. Surprisingly, the battery level gauge in the menu bar is all red and the Control Strip shows a fully charged battery.
In the menu bar, at least with the OS 8.6 I am running, the red vertical bar or cylinder is a capacity gauge; when all red, the battery is full; as power is consumed, the red starts dropping down and the top is filling with blue. Your gauge indicates a fully charged battery.
The only time you see the lightning bolt is when the battery is charging and you will see it in the menu bar and the Control Strip.
You know the power adapter is connected by the presence of the plug in the Control Strip.
The bars in the Control Strip are all gray when the battery is fully charged and all white when empty.
Remove all power and take a look in the battery bay with a flashlight; gently touch each pin with the eraser-end of a pencil and see if any of the pins is loose or possibly set back beyond the others.
According to Apple service guides, if you have performed the resets and have a known-good battery and power adapter, the only fix is a logic board.
Do you have a 45w power adapter and have you tried another power adapter? You can use the PB1400 or 3400 or any G3 or clamshell iBook adapters.

DV4 Battery Issue - Battery Charges; But Laptop Won't Run From Battery Power

Greetings,
I have a DV4, and let me tell you - I am so over this laptop. I have had it for over a year, and in that time, the backlight went out 6 months into owning it, the battery died just after the one year mark, and the webcam has been broken since I sent this computer back to HP to have the backlight issue resolved. I will never buy a new HP ever again.
Now, the battery I have replaced in my laptop charges - but, when I unplug the laptop from the wall, the battery power does NOT switch over. I have had this battery a total of two weeks - it was working fine until last night. Any ideas?
Thanks!

Hi, SoCal Cal. Take a good hard look at your battery contacts: both the ones on the battery itself and the "prongs" in the PB case that engage with the slotlike contacts on the battery. Are any of them significantly darkened/tarnished? Is there any debris or fluff on or in them? Clean out any foreign matter, then insert and remove the battery at least a dozen times in succession to see whether doing so will wear away any tarnish that may be impairing the necessary electrical connections. There's not really any easy, better way to clean the contacts, at least not the ones in the slots on the batttery itself. Then test again.
It sounds to me as though not all of the battery contacts are making good contact — though some of them obviously are, at least some of the time. Perhaps "working" the contacts this way will improve matters.
I really don't know what's going on with your machine; these are just shots in the dark.

Powerbook Ti Gig Ethernet won't run on battery

After killing a brand new battery, I opened my TiBook and found that the battery connector was loose. Tightened that down and , while I was in there, replaced the PRAM/Battery, but the computer still won't run on the battery. Bought another battery, and it recognizes a battery is there, and reports that it's 76% full, and the power connector is orange, and the computer reports it's calculating the time until full. But it never is able to calculate a time, and if you disconnect the power, the computer immediately shuts down.
Have reset PMU, NVRAM, PRAM, etc. etc., no change in symptoms.
Any other suggestions??

Hmmm. OK, I withdraw the previous suggestion. Let's assume the battery is OK. But clearly, although the Powerbook "sees" it, and therefore it is at least partly connected to the Powerbook, it isn't able to deliver power to the machine in whatever way is necessary to make the machine run. Because you've already had occasion to tinker with the battery connector, I suspect there may still be a fault there: one bad contact, a broken wire, or something similar. How about diving back in and making sure all the battery contacts inside the compartment are clean and undamaged, and that the connector from the battery to the logic board is securely seated.
If that investigation yields no clues and the issue remains, you may have a faulty Power Management Unit on the logic board. I doubt that a faulty AC adapter or a faulty DC-in card (the other two components of the charging and power systems) could prevent a healthy Powerbook from running on battery power with a healthy new battery in place.
I'm not sure how thoroughly, if at all, the Apple Hardware Test disc that came with your machine is able to test the power management system. Try running it and see whether anything shows up. Post back with results.

17" MacBook Pro won't run on AC power

Ok, this is a unique situation and I have searched the forums and can't find an answer, my early MacBook pro will not run on straight AC power, it will power up and run on battery power and the battery WILL charge while the machine is powered OFF but will not charge while the machine is on, so anybody have a solution?
Will run on battery power, will not run with battery removed on AC Only, battery will charge with AC adapter ONLY when machine is powered down, will NOT charge when machine is on.
Thanks for your help

Ok, booted into safe mode still same results , won't run on AC power, turn unit off light turns orange on power adapter and battery charges as normal, AC adapter plugged in light is green not charging while unit in on and will not run with battery removed, if I remove MagSafe it intermittently turns orange then back to green....Still perplexed as machine knows AC adapters connected and will charge but will not power or charge when unit is on.

How can i use an external screen on mountain lion when i'm running on battery power?

Hey all:
I just upgraded from snow leopard to Mountain Lion, and i use external screen, keyboard and mouse all the time....
On Mountain Lion it's perfect when the power adaptor is connected as soon as you close the LID your external screen becomes the primary screeen and it's fully functional desktop (no mirroring or extension screen)
But the problem is when i'm in battery power, in snow leopard i used to close my lid my mac goes to sleep then i wake it up using the mouse and immediately open the LID so it doesn't go to sleep again and now i'm running on battery power with a primary external screen.
Any idea how to use an external screen on mountain lion while i'm on battery power? (i know i can use mirroring but i want just 1 primary screen and the laptop screen would be turned off )
Thanks for the help.....

You can't with the lid closed, that's one of the rules for clamshell mode.

Can't run on battery power....

I had a lot of problems with my MBP which Apple diagnosed as a logic board issue. I just picked up my computer after having the logic board replaced. I haven't used it long enough to see if the freezing, etc. has been eliminated, but one problem remains.
I was unable to run off battery power for more than 20 minutes. It would eventually just go black and I'd have to shut down. I'd start back up and it'd have 80%+ battery life left. Apple checked this issue and put other working batteries in and the problem still existed, so it wasn't a battery issue.
This problem remains even with the new logic board.
Does anybody know what this could be?

Try the remaining items of:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Caution: Your computer is currently running on battery power.......

HP G72-227wm Notebook PC
WIN 7
Pentium Dual Core CPU
64 bit OS.
Had HD failure, could'nt perform recovery. Contacted HP and ordered Recovery Disc.
Disc arrived today, Bought a new HD as well as a Battery.
Put new HD and Battery in the computer as well as Disk 1 of the recovery disc set.
Computer starts, brought up loading windows, recovery manager came up, then........
Caution: Your computer is currently running on battery power. This process requires the computer to be plugged into AC power. Plug your computer into AC power. and then click OK to continue.
Of course the computer is plugged in, I have switched the power outlet 3 times. When the AC power is unplugged there is no light next to the AC port. AC power in port, White light then orange.
HP tech says thats because its CHARGING the battery.
****side note- after being on the charger the light is now constant white. Assuming the new battery is now completly charged.****
I have tried the following sequences with the tech:
Unplug>take battery out>plug the computer in with Disc 1 from the recovery set>restart> Same Caution:
Unplug>take battery out>hold battery power button for 40 seconds>re-insert the battery>plug the computer in with Disc 1 from the recovery set>restart>Same Caution:
After a considerable amount of time on the phone the tech says that my computer is obsolete and no longer serviceable by HP and advised taking it to a local computer shop.
This was not an issue before the HD failure. I hope someone can assist.
Thanks

Hi @mbaysfpd ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue of the HP G72-227WM Notebook giving you the error message your computer needs to connected to the AC adapter.
Could it be possible that when you replaced the HDD you accidentally loosened the connector inside the notebook to the Ac adapter?
Is it loose or wiggles? It could need to be soldered again.
You could look at this post it might have something in it that might help.
Please let me know how things go.

Dv7 Laptop won't run on battery

Laptop Data&colon;
[Image Removed]
Upon unplugging my laptop last night, it simply shut off, and since won't run off of the battery. It seems like the battery isn't connecting to the motherboard, but I ran a test in the support assistant that gives me this:
[Image Removed]
Is one of the cells dead, and that is why it isn't working, or could it still be failure to connect to the motherboard?
I have another battery, but unfortunately not currently with me.
The battery also won't charge past 86%, but again, I'm unsure of the cause. I left it out overnight and long held the power this morning to no avail as well.
Any help is appriciated. Thanks.

I understand your notebook battery no longer powers the notebook and the battery test has failed.
Reviewing the battery test, it looks like the battery (when fully charged) is only holding about 35% of the original charge. This means that the battery life wont' last very long as it will drain much faster. This is the most likely reason that the battery is no longer functioning is that it has reached the end of its usage. The battery test requires the battery to interface with the motherboard for it to test the battery, so I don't find the motherboard very likely at this point since the test was able to detect the battery.
You stated you have another battery to try. Try using that battery at your convenience to see if it can power up the notebook before purchasing a new battery. Should you proceed with a new battery, the replacement part number should be listed on the current battery.
Let me know if this answered your question.

Brand new macbook won't run off battery, only when plugged in

I just go my new macbook last week and being new to mac computers, I didn't realize that it won't run from just the battery power until last night. The battery light shows it's fully charged. If i'm working with it plugged in and it becomes unplugged, it shuts down and when I reconnect the power cord, it resumes from the same webpage or whatever I was last working on. I opened up the battery compartment and removed the battery and then held the power button for 5 seconds, but that didn't fix the problem. Does anyone know what I might try or if something needs to be set up in order to run off the battery? Thanks! Leigh

Hello leighdk,
Welcome to Apple Discussions!
You can by all means take some good advise from the people on this board in response to you problem.
But here is the best advise, especially since you're new to Mac.
Call Apple Care or take it back to the store and have them check it out. It is under warranty. You have 14 days from the date of purchase to return the Mac for a completely different or give it back because you do not like it. they may try to charge you a restocking fee but this should not be the case since there is an issue with you machine.
Call Apple, see what they say... Then if you can't get it resolved then post back and maybe we can give you some sound advise.

MBP won't run on battery

As of a couple days ago, my MacBook Pro won't run off its battery. When I press the button, all the battery lights light up, indicating a full charge. But the computer won't turn on. Only when I plug in the power adapter does it work. If I pull out the adapter when the computer is on, it shuts off.
Yesterday, I noticed something peculiar. The light in front, which normally pulses when the computer is in sleep mode, was sort of half-pulsing. It would slowly fade on, then immediately flick off. Not sure if this is an indication of anything.
Is this definitely a hardware problem? I have an appointment to see a Genius tomorrow, but I'm wondering if there's something I can do on my own first.
Thanks.

IBook won't run on battery

Hi Folks
Wondering if someone can point me in the right direction here. I have an iBook G3 900 mhz model that I just replace the logic board in (video issue). The ibook runs great now, but all of a sudden it won't work with out the power adapter plugged in. I thought maybe the battery went bad, but I checked it in my other iBook and it is fine.
I bought the Logic board at a discount because it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine. and it even worked with just the battery for a short while, but now only works with the adapter. Should I open it up and re solder the connection, or is this another issue?
Thanks
Don

Hey Don,
I have an iBook G3 900 mhz model that I just replace the logic board in (video issue).
Just curious. Did the GPU chip die? or was it the BGA issue? I repair and donate iBooks to inner city school teachers.
it had a missing plug in connector, which is the one that connects from the Logic board to the power button. I soldered it back on and powered up the Laptop fine.
Wow good job! That's not easy to do. BTW that plug would have nothing to do with the not running on battery problem. It's part of the "soft start" circuit.
This is from the service manual for the 900:
"The computer runs when plugged into a wall outlet but not on battery power
1. Reseat battery to verify battery is seated correctly with battery lock engaged.
2. Try known-good charged battery.
3. Reset the power manager by pressing the key combination Control-Option-Shiftpower.
Warning: Make sure you do not hold down the "fn" key when resetting the
power manager.
Warning: Resetting the power manager will permanently remove a RAM disk, if
present, and all of its contents. You will also need to reset the date and time
(using the Date & Time control panel).
4. Replace logic board."
That "power manager" they speak of is a PMU 99 which I believe is CMOS and very sensitive to static charges.

AC adapter bad? Powerbook won't run without battery

I think my powerbook (G4 aluminum, purchased Dec 2005) AC adapter is bad--the powerbook won't boot up without the battery (which, thankfully has not been recalled!).
I did check the AC issues listed in this Apple doc:
http://docs.info.apple.com/article.html?artnum=302461
The light on the adapter is green, the battery charge indicator menu states "Charged." However, none of the 5 lights on the battery are lit when the AC adapter is plugged into the computer and an outlet.
I have both AppleCare and ProCare--would a replacement AC adapter be covered under either plan?
P.S. the logic board was replaced in this powerbook last week by Apple because the computer would not boot up, there was a loud "fan" sound and one beep every 3 seconds.
Anyway, help!
powerbook G4 ( Dec 2005) - ARRRGHH! Mac OS X (10.4.7) and ibook G3 (10.3.9) -- never any problems!

I appreciate your advice! I agree that I should take in the powerbook for another round of repairs. However, I want to get some idea of the possible causes of this problem before returning it. Here's why:
[warning: venting ahead]
I am not taking it back to the nearest Genius Bar because of the poor, indifferent service there. Specifically: first guy guesses that the logic board needs replacement, and says the contents of my hard drive are not "protected," then tries to sell me ProCare, which has some kind of hard drive back up deal included. Since I hadn't backed up in months, I bought the Procare contract.
The next day, a different local Genius tells me that the hard drive could not be recovered, it was the cause of the computer crash, and just the hard drive will be replaced at the factory, and it will take 2 weeks.
Two days later, another Genius calls to say my computer's ready for pick up. They replaced the logic board, and the hard drive is fine--untouched. Hurrah.
I used my Procare status to get a Genius appointment to pick up the computer. Yet another Genius doesn't want to listen to my complaints about the "hard drive disaster Genius." I make him turn on the computer [battery power] to make sure the hard drive is OK (yes). I am then shooed out the door.
This is why I don't trust the local Geniuses to examine my computer again. The second nearest Apple store is 25 miles away, so I guess I'll go there for future repairs.

Ipod won't run on battery

I recently took my Ipod with me while skiing. During the day it stopped working. I assumed that when it warmed up later it would work normally but it will not run on the battery at all. It works fine when running on external power such at the power cord or when attached to an audio player. The battery indicator shows fully charged when plugged in but it will not play once removed from the power source. Did the extreme cold (less than 10 degrees) kill the battery and do I need to have it replaced?

The extreme cold and moisture has probably finished off the battery.
You can try letting it "run" for 24 hours and then Restoring it in iTunes, then fully charging it. If this doesn't work, it is time for a new battery.

G560 won't run on battery

Facts:
laptop under a year old
lightly used
running fine on battery yesterday
battery meter shows 99% charged
What happened:
Using laptop last night on battery, hit 7% and I plugged it in. Finished what I was doing and shut down windows applied critical updates. This morning unplug laptiop and try to turn it on...nothing. Plugged it in and it started. Tried a couple times disconnecting battery and reinserted, battery meter working, shows charged just won't work on battery. Tried to roll back to previous restore point, as I didn't know if it was windows related. Still nothing. Read to leave it unplugged for a full minute...nothing. Any ideas?
Again the battery is not old or worn out, it held a multi hour charge yesterday.
Thanks

take a look at the thread below first. if it doesn't work, you'll need battery replacement.

Battery stopped charging; won't run from battery

A couple of days ago, my computer stopped running from battery, and stopped charging the battery. I can see that the level is 67%, but that never goes up, and it shuts down if I unplug the power adapter.
Here is XBattery info:
Installed: Yes
Charging: No
Charger: Yes
Battery%: 67
Max. cap: 4.400Ah
Curr. cap: 2.271Ah
Charge: 1.534Ah
Voltage: 11.850V
Amperage: 0
Cycles: 680
Flags: 41000005
Anyone know how I can fix this?

I have the same issue with my Powerbook G4 15" Aluminum (battery not charging and clock not retaining date and time). A 3rd party warranty company is trying to say it's the rechargable battery but I think it's something to do wit hthe small battery located on a daughter board on the motherboard. Can anyone verify this or does this sound like a totally different issue?
The battery was replaced under the recall less than a year ago.
Thanks,
Bob
