MacBook Pro battery level indicator is stuck at 100%

Got this MacBook Pro in January of 2008. Great machine, replaced battery last spring and more recently had some sort of repair done when the screen would not activate. No problems otherwise. Now all of a sudden my battery level indicator is stuck at 100% regardless of actual battery charge level. The computer will allert me that it needs plugged in immediately or it will go to sleep, but it would be nice to have the indicator working again. Any ideas?

If it's a pre-unibody MBP with a removable battery:
1) Shut the computer down
2) Disconnect the Magsafe AC adapter
3) Remove the battery
4) Hold the power button down for 5-6 seconds
5) Reinstall the battery.
6) Connect the Magsafe adapter to power and turn the computer back on.
This will reset the System Management Controller. One of the SMC's functions is reporting of the status and remaining charge of the battery.

My macbook pro battery will not hold charge

My macbook pro battery will not charge. The laptop will only turn on after it has been plugged in to charge, and when unplugged it automatically dies. When plugged in the battery indicator is green and the top right corner of the screen says "Not charging". I left town for a week with the laptop off and I came back in town and it won't charge. What can I do to fix this?

If you are under warranty call Apple and get a case number.

My MacBook Pro battery is empty and won't charge, but charger is fine

My MacBook Pro battery is empty and won't charge. I did the PRAM reset when there was still some power left in the battery. The charger indicator light doesn't come on when I connect it to MacBook Pro, BUT it works just fine with my old white Mac book. This happened a few times before, and unplugging and plugging the adapter into the MacBook pro helped. Now nothing happens no matter how many times I reset the charger. Is there anything else I can do?

More than likely you need a new battery.

How is the best way of keeping your macbook pro battery healthy

what is the best way of keeping your macbook pro battery healthy there are so many ways what is the best way?

Read these two Apppe articles:

I generally keep my MBP connected to AC as much as possible and try to make certain that at least monthly I run it on the battery to about the 40% charge level.

I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%. How is this possible when it's plugged in to the charger and the green light is on?

The system regularly lets the battery drop to about 95% when on the charger, then recharges to 100%. This lets the batery exercise "just a little" all of the time and saves the recharge curcuits from overuse.
Regualr occurence for me.
Also ... you need to let your battery work at least once per month. Let it run down to 40%, but not less if you can at all avoid it. Running thr battery fully dead will shorten the battery life significantly.

Connect to iTunes and restore. If you have difficulty, you may have to put the device into Recovery Mode. See the instructions in this support document. If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support

MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

The firmware update corrects an error that may occur, however the techs would have checked the condition of the battery prior to installing a new one. If the battery was questionable, the firmware update was really not too important.
You can check the battery condition by going to the apple, left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about Cycle Count, Condition, Capacity: Condition anything but Normal needs to be checked and may need to be replaced.
The cycle count of 1,000 charge cycles is the typical life of a Lithium-Ion battery, the point at which the capacity drops to 80% of the as built capacity.

MacBook and MacBook Pro Battery Update

http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Apple has recently discovered that some batteries used in its MacBook and MacBook Pro notebooks may have battery performance issues. Apple is offering a software update that is designed to improve battery performance.
The battery update is available immediately via Software Update or downloadable here.

For MacBook and MacBook Pro systems with Intel Core Duo processors, this program extends repair coverage on the battery for up to two years from the date of purchase of the computer.
Identifying an affected battery
Affected batteries will have one or more of the following symptoms:
Battery is not recognized causing an “X” to appear in the battery icon in the Finder menu bar.
Battery will not charge when computer is plugged into AC power.
Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300.

Pretty nice change for those C2D's

Dota 2 and Macbook pro battery

My early 2011 15 inch macbook pro battery drains while connected with 85w charger when i am playing dota 2. Dota 2 runs faily well with very little lag in almost high setting. Shouldn't 85w charger provide adequte power for gaming. Dota 2 is not even a very demanding game. I have only played few small 2d games in my pro and this may be the first time i am playing a 3d game. And also sometimes it doesnt drain even when i play 2-3 matches but most of the other times it drains in single match. I have yet to see it drain down 90% but still. What options do i have to fix this? I am graphic designer so i sometimes do video editing in my macbook pro and i m quite sure some of those renderings are more system hungry than dota 2 and no drain while doing that. Thanks in advance.

What do you mean it didn't work? Are you having a battery issue that the update did not fix? Need some more info. If you look at the webpage that I linked to, it advises to have affected batteries replaced.

Note: If your MacBook or MacBook Pro battery does not have any of the symptoms noted above, your battery does not need to be replaced.
If you're replacing batteries every 3 months I would take a look at how you are maintaining your battery. Are you calibrating it when it arrives and then every 6 to 8 weeks afterword? Are you running graphically intensive programs? Do you have a lot of background process in your activity monitor that are taxing the system? Most folks I have seen post here find their battery issues resolved after a replacement, not recurring every 3 months.

HT204347 Do you connect the charger in the MacBook Pro battery damage if using device ?

Do you connect the charger in the MacBook Pro battery damage if using device ?
i am sorry i not good speak english

Provided you are using the correct charger for your Mac (13" have a 65 watt charger, 15" and 17", an 85 watt charger), it has enough capacity to power the computer for normal tasks, and the leftover power can charge the battery at the same time. If you are doing something very intensive, there may not be leftover power, but the Mac will take power from the battery if needed. Once the battery is fully charged, the pilot light in the charger plug will change from orange to green and no further charge will be applied to the battery.
You can use your Mac plugged to the charger with no damage to the battery or the computer.

Excite Pro - Battery Status Indicator at 0%

Battery status indicator is stuck at 0% - battery holds charge ok just don't know what it is. I presume the battery stats file is corrupted - is the only way to fix it a factory reset?
Calibration either needs root - not possible or 60% charge - won't work as says 0%!!!!

I think you should set it to factory settings.
Press and hold power button and volume up button. Then in the menu choose factory reset.
If this will not work, then the issue must be related to hardware failure
