Macbook Battery Recognised, But Won't Charge

Hi, purchased my macbook April '06, and it's just started mis-behaving. When switched on, the adapter light is green, there is a plug in the battery icon to indicate it's running off the mains. Clicking on the battery displays the percentage charge, however, this doesn't increase. The battery has 174 cycles on it and I have tried resetting the SMC as described in the apple support pages, to no avail. Has anyone else encountered this problem or am i going to be forking out for a new battery? (I have the latest updates including the battery update)

Thanks for the .

Macbook battery, and replacement, won't charge

I have an early 2008 white macbook. The battery recently stopped charging. The icon on the menubar reads, "Condition: Replace Now." I installed a new battery and also bought a new mag adapter powercord. Still no luck. The computer runs if the powercord is plugged in - but not on the batter. Thoughts?

Thanks. Took it in to the local Apple reseller. The problem was a bad "new" battery that didn't fit. Watch out for "Newertechnology" NuPower batteries. Got mine from OWC. Put out the extra cash for an Apple battery and, what do you know, it worked. That's what I get for cheaping out. Guess there's some wisdom in the cliche, you get what you pay for.

Macbook turns on but won't charge.

Ok, so here's my quick story. Iced tea was spilled on part of my macbook about 2 weeks ago. It turned off and wouldn't turn back on. Later that day it turned on for about 30 mins and then turned back off. No noises were made, it turned off quietly. Macbook would not turn on for over a week, battery still showed power. Mac turns back on today, appears to be working normally. My personal charger will not charge the mac, my friends charger also does not work. The light doesn't come on the charger and nothing happens. What is wrong with my mac?
It also will not power my macbook, it doesn't recognize that its plugged in.

Welcome to the forums.
Anytime liquid is spilled on anything electronic. It should be turned off and the battery removed. Never turn it on until you give it a chance to dry out.
It sounds like your MacBooks circuitry has shorted out in the charger section and possibly other areas. It is hard to say without testing on the bench. You will need to have it serviced by Apple or another repair service. Do a search on the web and you will find some that does work cheaper than Apple and will give a quote before repairs are done.

Bought battery for ibook G3 but won't charge up?

Hi, my original battery for my iBook G3 600 was almost dead so I bought a replacement. I have been using the battery only for about a week now & charged it up only a few times. Everything was fine until last night.
I put the ibook to sleep until this evening, when I tried to boot up I got nothing? There is a slight wirr in the background but no screen?
I decided to test the iBook with my old battery as there was still a little life left in it. The ibook then booted up no problem?? I dont understand it?
Can anyone help me with this problem? Be much appreciated...

The green light means the battery isn't charging. When everything is running right, this means the battery is charged but when things aren't working right, it simply means the battery isn't charging (for whatever reason).
These are the four most common possibilities when the battery will not charge:
(1) there is something wrong with your battery
(2) there is something wrong with your power adapter
(3) there is something wrong with your power input board (the part that contains the port where you plug in the adapter)
(4) there is something wrong with your logic board
In your case, since you've already replaced the battery, eliminating it as the problem, it is likely either a bad power adapter or a bad power input board.
Do you know someone with a known good adapter, or could you take it in to an Apple Store to have them check it out to see if another adapter will charge the battery?
The power input (DC-in) board (the part of the computer which houses the adapter port) may be going bad if it sometimes will charge the battery and sometimes won’t. Sometimes it will work intermittently before quitting entirely. When a DC-in board quits working, the computer will run fine from the battery, but won't run from the adapter, and the adapter will no longer charge the battery. To diagnose a bad DC-in board, you need to make sure it isn't the battery or the adapter at fault by swapping out first one and then the other, If it runs from a known good charged battery okay, but won't run from a known good adapter, then you are going to have to replace the power input board.
Usually, if it is a logic board problem, the iBook simply will not run from the battery. This happened to mine. The battery showed up in the battery status indicator. It was recognized by the computer and charged by the adapter (as shown by the battery status indicator). However, when I unplugged the adapter from the iBook, it was just like pulling the power cord from the wall on a desktop. The iBook immediately shutdown. Dead.
My husband’s problem was quite obviously the power input board because the adapter tip had broken off in the port. Often (and, sadly, in our case), this damages the power input board so that it no longer functions, necessitating replacement of the board as well as the broken adapter.

It sees the battery but won't charge it: brand new battery

I had an old (~4-yr-old) battery that had been holding up pretty well. Then one morning, it would no longer hold a charge at all -- if I unplugged the AC adapter, the laptop shut off immediately. The computer still "saw" the battery in the menubar, but was stuck on "Calculating..." and never got above 0%.
I reset the PMU, no help. I ordered a new battery.
The new battery just came, and it has about 10% charge on it as indicated in the menubar. It is stuck on "Calculating..." and the charge is not increasing.
The computer knows the battery is there (no "X" through it) and can even run off it (if I unplug the adapter, computer stays on and shows red-line level in battery icon) but will not charge it.
I've reset the PMU (several times), zapped the PRAM, and reset the nvram. The battery contacts look clean (no obvious dirt or corrosion).
I don't see the Battery Info in "About this Mac..." (it's not listed at all; is this because I'm in OS 10.3.9 or is something else wrong here?) but using ioreg at the command line I get
"IOBatteryInfo" = ({"Capacity"=4200,"Amperage"=0,"Current"=435,"Voltage"=15282,"Flags"=325,"Absol uteMaxCapacity"=4200})
Any suggestions are greatly appreciated! Especially since for the last few weeks I've been stuck using my laptop essentially as a desktop computer, very frustrating. Thank you

Hi, m.g.h. Have you ever tried a different, known-good AC adapter, just to eliminate the possibility that the problem resides there? If you plug the adapter in and the adapter ringlight glows green, turn the Powerbook over and press the button on the battery. The lights on the battery should glow green and stay on if the adapter is working correctly.
I don't see the Battery Info in "About this Mac..." (it's not listed at all; is this because I'm in OS 10.3.9...?
Yes, it is. That info doesn't appear in Panther's System Profiler, so you were right to check it in Terminal.
Your battery is obviously connected to the Powerbook, given the Terminal readouts. That being the case, it would seem that the possible causes include a bad (though new) battery; a bad PMU; a bad DC-In board, if you have a DVI Tibook; and a bad AC adapter.

Your battery has reached the end of its life. If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay.

Macbook pro recognizes but won't print with hp desk jet 5550. Help!

macbook pro recognizes but won't print with hp desk jet 5550. Help!

Hi, I used the Mac setup instructions, not the PC ones. The printer was automatically recognised in print and scan when I connected it with a USB cable. I accessed the server's web-based page and followed all the instructions, but still no joy. Thanks for the tip about posting. I have just posted in the section you suggested, so let's see what happens. From a quick scan around the apple forums, lost of other people seem to having precisely the same problem (and not just with HP printers!), but unfortunately, no-one seems to be offering a solution! And trying to get through to the apple online support is a complete waste of time. They've been 'not available' for two days now. Christmas/New Year shutdown, I suppose. Thanks for all your help, though!

My MacBook Pro retina 2013 won't charge. I've checked all connections which are all ok. Little red light shows on magnetic plug, instead of usual green.

My MacBook Pro retina 2013 won't charge. I've checked all connections which are all ok. Little red light shows on magnetic plug, instead of usual green.

If you are seeing a Red LED, you may have a faulty MagSafe Adapter.
I remember reading that the orange light is produced by a combination of a Red and Green LED. If that's the case, It seems that the adapter isn't lighting the green LED properly at that time.
I would suggest you seek service with your nearest Genius Bar (Apple Retail Store) or Apple Authorised Service Provider as they have access to diagnostics which may assist in isolating any hardware issues you may be experiencing.
Cheers.

My ipad(2) is plugged into my pc but won't charge-any ideas?

my ipad2 is plugged in but won't charge-any ideas--only 2 weeks old

Your PCs USB port is probably not capable of providing enough power to charge your iPad. It might be charging at a very slow rate and when your iPad is in sleep mode. Use the adapter provided with your iPad.

Why doesn't my phone charge? I changed the battery, now it won't charge at all and it's almost dead.. Any suggestions on how to fix it?

iMessage and FaceTime went down yesterday for some people. Mine is still down. My iMessage is saying the same thing about being activated. Sounds like you are still down too. Ignore the status page that says everything is fine - it lies.

TS3499 macbook recognises but will not charge new battery

I was advised to buy a new charger last week and have just been advised by an apple employee to buy a new battery for my MacBook 2009 and i am having the same issue as my old battery.
The Mac reconognises the battery but will not charge or run off the battery.
Just spent £150 in total on new charger and battery but still having the same problem as before.
I have downloaded the firmware update but my Mac is already running the latest software.

MacBook battery discharging but not charging

Hello,
I have a MacBook 2,1 that has been having some battery issues. My Mac runs fine off of the MagSafe adaptor and it also runs fine if there is a battery installed that has a charge on it. But my Mac won't charge my battery nor does it recognize my battery. As I type this, I'm running off of the battery alone but I have a battery icon with an X on the menu bar. I recently had my mother board replace at an Apple Store due to an audio jack issue. My AppleCare expired shortly after I had this repair done. If anyone knows what might be causing the problem, I'd greatly appreciate any help. And if anyone has had this issue fixed at an Apple Store, about how much can I expect the repair to cost?
Thanks.

Try resetting SMC

Thinkpad Yoga S1 Runs off AC but won't charge the battery

I have recently purchased an S1, which is now having an issue that I can't seem to resolve on my own. The laptop works (almost) perfectly on A/C, but doesn't charge the battery. I noticed yesterday the battery was low (which was surprising, because I had only recently unplugged it) - so I plugged it in to charge.At which point, the battery icon in the system tray stated "8% (plugged in, not charging).I've tried the following to fix this: 1) Leaving it plugged in overnight completely off. 2) Running the battery calibration (fails w/ unexpected error). 3) Tried turning off battery optimization (Option is removed in newer version of drivers, so NA to my issue). 4) Tried reinstalling the power management drivers anyway (even though I already had the newer version). 5) Holding down the power button for 30 seconds, both plugged in and not plugged in (suggestion from forum). 6) Holding down the reset button (pin reset on the mobo) for 30 seconds, both plugged in and not plugged in. 7) Charging from BIOS. 8) Letting the battery run down to 0% in BIOS, then rebooting on A/C (another forum suggestion). Now I'm just at 0% plugged in and not charging. Previously I said the computer almost worked perfectly, the almost is that the CPU is stuck at ~800mhz, even with all power management turned off (including Speedstep in BIOS) and the power profile set to high performance. Can anyone think of anything else I can try before I give up and send this thing back? It was working perfectly for the last couple of weeks or so, including getting ~ 4, 5 hours of battery life, so unless the battery failed very suddenly I can't imagine why it would just start refusing to charge.

well I replaced the battery with another one I bought (exact same model for the battery SONY 45N1705, I was hoping I would get another battery version because I notice there is an update for the other battery revision that fixes issues with battery stopped charging. http://support.lenovo.com/us/en/downloads/ds001322. I forced the bios update from 1.07 to latest 1.24 using olydbg to skip the battery check. this did not help with anything relating to the battery. now I am stuck again where I was at the beginning..... im looking at buying a board replacement.... also I was looking at replacing the power supply but I check the voltage and the amps, and it is correctly matching what is written on the back of the laptop. still getting the 0% plugged in and charging.

Macbook late 2010 13" won't charge?! Please help!

Ok so my mom gave me her old Macbook (late 2010) 13" laptop after it stopped working for her. She claims she didn't drop it but there is a large hunk of plastic missing around the magsafe port and it will no longer charge and the DvD drive doesn't work either (only makes a very annoying sound upon boot or waking). I was looking into the usual charge cycles for this particular battery a while ago and I believe it was around 300 which I was about 50 over, so I went and bought a brand new Apple brand battery and installed it only to find that it, like the other battery, still won't charge. My Macbook recognizes it is there but just won't charge. It says that this battery only has one charge cycle which indicates that it is indeed brand new. The battery icon on my top bar used to say service battery until I replaced it, now it only says "Not Charging". Here are my battery specs and if you need any info to help me, PLEASE ASK. Someone please help me save this wonderful computer....

A brand new battery would require a full charge in order to be used;
so you are lucky, in that the new battery had enough power already.
So that is not an indicator of much, other than the MagSafe Board
in the computer itself may have sustained damages due to ???
and would need to be checked over by an authorized tech or if you
are near an Apple Store with Genius bar, call ahead for appointment
to have a diagnostic test done and take along the MagSafe adapter
so they can see if that is part of the problem.
Of course, an optical drive issue could be part of a diagnostic check.
If you are in the US or Canada, the retail Apple Store offers a free
service of a diagnostic, even though the computer is no longer
covered by an AppleCare plan. So that is worth taking a drive...
Check the details here, and follow them to see if you can make it go:
•Intel-based Macs: Resetting the System Management Controller
http://support.apple.com/kb/ht3964
•About NVRAM and PRAM:
http://support.apple.com/kb/HT1379
Are the contacts on both the MagSafe adapter and MagSafe port
clean, or do they have an odd color or debris in/on them? It is
possible to clean them of debris, but don't use watery stuff. A
tool such as a wooden toothpick could be used to see if anything
on there could be rubbed off or out of the contact areas.
Good luck & happy computing!

Macbook battery no longer holding a charge and not charging

I've already reset the PMU and PRAM and calibrated the battery, 3 times. The battery is now on 5% and won't charge any more. It's less than a year old.
Will Apple replace this piece of crap battery or do I have to shell out $130 for a new one? And is this a common problem?

Yep, they should send you a new one for free. Same thing as dalowang, I had a 3 month old MacBook and battery wasn't working. Apple sent me a new one but now it's happening all over again. Apple said it was a problem with my computer. Off to the far away apple store tomorrow. Anyone got any suggestions before I go?
