Won't display remaining battery power

I'm running 10.6 and the battery display only shows a 'Not Charging". The only options under 'Show' are the icon, time, and percentage.

Hi, KalaallitNunaat.
Thank you for visiting Apple Support Communities.
I understand that your MacBook pro is not charging. Here are some troubleshooting steps that may help.
My battery is not charging
Confirm the correct wattage AC adapter for the computer. A power adapter rated for a lower wattage than is required for the system may not reliably charge the computer. For assistance identifying the proper adapter, review Intel Based Mac notebooks: Identifying the right power adapter and power cord--US. Additional adapter troubleshooting is available in Troubleshooting MagSafe adapters. If issues persist please reset the SMC.

Macbook pro and Thunderbolt display on battery power no go.

I use my macbook pro mainly on my desk with the thunderbolt display and its lid closed. While having the power adapter connected to the macbook everything works fine. When I disconnect the power adaptor and try to wake up the computer it comes to life for a few seconds and then goes back to sleep for good. I cannot use the thunderbolt display while having the macbook on battery power. That causes the issue of the battery not discharging which I am aware is pretty bad. Any advice is welcome. Thanks.

I kind of figured this out. The reason I wasn't satisfied was that without the power adaptor when you hit a button on the keyboard the monitor actually wakes up the computer, works fine for a few seconds and then puts the computer to sleep. That kind of proves that it does work, technically at least. The problem is going into sleep mode afterwards.
Anyway i guess it just doesnt work. Thanks.
ps. If there is a way of discharging the battery with software while the power adaptor was still on, would be great help.

Macbook won't start on battery power

I have a six-week old Macbook. Was working just fine until today.
Now it will not boot up on battery power. Works fine when Magsafe is connected and the battery is showing that it's fully charged (100%). When disconnected from AC power it powers off immediately and won't boot up.
Have tried a SMC reset. Didn't help. Any guesses what the problem might be?
Thanks in advance.

Currently, there are two very similar problems with the MacBook batteries, I've found.
The first is that the computer IS recognizing that the battery is there, and the MacBook shuts down almost as soon as AC power is removed. The usual diagnosis here is that you have a bad battery.
The second variant is that the computer is NOT recognizing that the battery is there (the X through the battery literally means the computer thinks you have no battery connected), and the omputer behaves he same way as the one in the first scenario. This usualy means that you have another type of bad battery, or the battery does not have a full connection.
Either way, I reccomend that you follow these steps:
1. test the battery by pushing the small button next to the set of LEDs on the battery pack, and make sure the LEDs light up. If they do not, the battery is most likely deffective.
2. Make sure there is no foreign object or corrosion causing a bad connection with the battery. You should be ably to do this by removing the battery and looking at the metal contacts on both the battery and computer.
3. Make sure your software and firmware are updated. To do this, click the apple pull-down menu in the top left corner of the sceen, and select "About this mac". Then, click the Software Update button.
4. Reset the PRAM, PMU, SMC, and make sure the battery is properly installed. Find instructions on Apple's website.
If all else fails (or if the battery proves to b defective in step 1), call Apple or visit an Apple store to get tested, and replacements.
I hope this helped. Nobody bothered to answer my post, and I had to find this information out from a buddy of mine.

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.

Head scratcher--new HD, macbook won't boot on battery power

I needed a larger hard drive because the orig 60gb was getting full. replaced with a seagate 250gb. now, macbook will no longer boot on battery power. works fine if plugged in. if unplugged while running, macbook goes dead. battery is fully charged.
a puzzlement. any ideas, brain trust?
...joe

What is the model number of the HDD you bought?
Next, make sure you have the battery in all the way and that the HDD is securely installed. Then try a PRAM and SMC reset by shutting down, unplugging the magsafe, taking out the battery, and holding down the power button for at least five seconds. Next, put everything back and hold down commmand-option-p-r at startup until it chimes twice then let go.
If none of that works put in the old HDD and see what happens.

Lenovo s10e won't start on battery power alone

Hi,
I have the following problem with my Lenovo s10e netbook:
On battery power, press the power button, I see a flash on the screen, the blue power led turns on, then off after a few seconds, I can hear a sound from inside the device but it does not turn on.
If I connect the power adapter with the battery connected the device starts up with no problem.
If the battery is not connected and I only use the power adapter I have no problem starting the device.
I tried using a different battery and still have the same issue.
Do you have any idea what is causing this?

hi icelexy,
Welcome to the Lenovo Forums.
The unit looks like it's not getting enough power on the battery. If you're using the original 6 cell, 4400 mAh. 11.1 V battery, there's most likely a problem on the charging mechanism at the back part of the unit.
Have you already contacted lenovo to report the issue? (they'll most likely ask you to send the unit in for diagnosis)
Regards,
neokenchi

T410s won't boot on battery power

This is a relatively new problem (i.e. it didn't happen when I first got the laptop). If the computer is fully off, and I unplug it, I press the power button and nothing happens. When I plug it in, I can turn it on no problem. Sleep mode on/off is unaffected by this.
I sent it in for an RMA a while back and they said the battery didn't pass tests. They sent me a new one but I'm still having problems. Any ideas? Is it a setting somewhere I'm missing?

hey kayson,
i would recommend that you get in contact with tech support via the link below

Ti G4 PB Won't Shutdown on Battery Power

Shuts down OK on AC power.
PowerBook G4 Ti 667MHz Mac OS X (10.4.8) 2 GB RAM

Thanks for reply. Leaving on trip tomorrow and don't have time to run test until I return next week. Will provide more info then. Thanks again. All I can tell you now is that it looks like it is off after I shut down, but the LED below the screen keeps fading in and out and never goes out. I did not make certain that all applications were closed before I shut it down

"No battery power remains. Please connect iPod to power."

I plugged my iPod into my laptop last night to sync/charge it like I always do, with no problem... today I unplugged it and turned it on, and after about 30 seconds it shut down, saying that my battery was dead. I brought it back and plugged it in... if I plug it in via USB cable, it just says that my battery power is extremely low and to please wait, and every few minutes it will light up and show the black screen with the silver apple, then just go back to "please wait". If I plug it in with a wall charger, it works, but it says it's fully charged, and as soon as I unplug it, it displays "No battery power remains. Please connect iPod to power." It still registers on my computer (as long as I start it with the wall charger, then switch the cables quick...), and I restored it, but it's still saying it's fully charged, and I know it's not. I've also tried resetting it a few times.
Help???

I just had a similar problem with mine... It's like it gets into a loop where it's trying to boot up before there's enough charge. I've managed to break the cycle and get a charging logo on the screen - although I don't yet know whether this has fixed the problem.
I suggest you let it run completely dry and then plug it directly into your computer. Don't press any buttons and it possibly might make a difference whether Itunes is running (I think it was off for me). Hoepfully, if you leave it for half an hour or so, it will get the battery charge to a reasonable level where you can continue normally.
I kinda stumbled on this as I was playing around, so not sure whether the steps above are what improved the situation.
Hope there's some helpful info in there.

2011 MBP not dimming on battery power

My new Early 2011 MBP is set to slightly dim the display on battery power and it is not dimming on battery power unless i go in to the energy saver preference and uncheck and recheck it then it dims slightly.

Yes, the case is a heat-sink; Apple call them "notebooks" not "laptops" and warn against having them against your skin.
"Do not leave the bottom of your MacBook Pro in contact with your lap or any surface of your body for extended periods. Prolonged contact with your body could cause discomfort and potentially a burn"
MacBookPro_UsersGuide page 107
Actually, you don't want heat near the battery itself as that's not good for li-ion, that should feel relatively cool?

Battery won't Charge, but shows "power source: power adapter"

Ever since beginning of Oct 2013 my newish (bought macbook pro retina display july 2013) decided it will no longer charge my battery, it will only provide power but nothing else. I tried using my old magsafe adapter with a magsafe 2 connector and manage to charge battery but that is also a battle to have it in right position and only after i plug in and out about 10 times. It is quite annoying, is this fixable or do i need to replace battery.
I have seen loads of other posts but not too many recent ones. Anyone having the same problem?

Thanks Clinton.
Only problem is i got my laptop in USA and I live in SA. No one really willing to help as they deem it out of warranty as not purchased here. I am going to take it in somehwere and try see if they can try with new magsafes. I have an inkling maybe might be problem with connector, but who knows. Failing that might have to suck it up and ship it back to states and miss it for couple weeks.
I did try do SMC reset, made other adapter work for like a day then nothing.
thanks again for help.

MacBook won't start on battery/shuts down when power adapter is removed

Help & advice needed please.
My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
The battery shows at 98% & charging. Coconut Battery shows the following:
Current battery charge 4126 (& increasing as I type)
Maximum battery charge 4200
Current battery capacity 4200
Original battery capacity 5200
80%
Battery loadcycles 111
Age of your Mac 6 months
Charger connected yes
Battery is charging yes
Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
Cheers!

As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

No battery power remains...

Hi. My nano's battery died and the screen has said "no battery power remains. please connect ipod to power." for hours now. when I plug it into my computer, neither my itunes or my ipod recognize that it's plugged in and it's not recharging. Is my battery actually dead, dead?

+Important: iPod will stop charging if the computer, or portable computer, it's connected to enters standby, hibernation, or sleep mode. To charge your iPod, connect it directly to a computer's USB port and make sure standby, hibernation, or sleep mode is turned off.+
+Note: If using a portable computer, make sure it is plugged in to a power source and that the lid or display is open. If the lid is closed the computer may go into either standby, sleep, or hibernation mode and iPod will not charge properly.+
