MacBook :: Battery Icon Sometimes Shows No Battery Or If It Shows Battery Is Recognized, It Isn't Charged
Jan 4, 2010
I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

I don't get this. My mom's white MacBook (Intel IGP model) showed an X across the battery like it doesn't work, so I bought her a new battery for it. However, I installed the new battery and it still shows an X but it actually does work. I figured it out by accident. I thought maybe I bought a bad battery. I tripped over the magsafe and the MB stayed on... confused, I am now here. Not finding much about this.
What causes OS X to display an X across the battery icon? Doesn't this usually mean the battery is ruined? When pushing the button on the bottom of the battery, it shows five LEDs as it's fully charged and working. I unplugged it several times, and the MB stays on.
It also reduces the screen brightness and seems to go into battery power saving settings when unplugged. So how do I get OS X to see the battery? It must be charging properly as it's not hot or bulging or anything at all.
The problem is simply that it's not showing the battery information at all as though there were no battery plugged into the MacBook. But it works as though it's plugged in and all is normal?

I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?

when I fisrt noticed this I thought it was the charger, but I bought a new one and the battery still shows a 95% charge but never reaches 100%! Could it be the battery?

i very rarely use my MacBookPro away from home (scared of loosing it, LOL) almost all the time it is plugged into the mains 24/7, i just shut the lid when i am not using it. It is about 12 months old, but i notice that the battery meter never goes above 96%, does this mean the battery is on the way out and is going to get progressively worse ?I suppose it means the battery isnt going to last anywhere near 6 or 7 hours if i did unplug it from the mains?

for reasons I won't go into, I had to re-init my SSD and restore from a TM back-up. I used to have a little app that had an icon in the menu bar showing what graphics mode was being used while on battery/charger. I swear I can't remember the name of the app. It was useful for making certain that the right graphics mode was being utilized (amongst other things).
It's not Battery Health - I can't recall it at all. I obviously didn't get it in the App Store because nothing like that is showing up in my purchases.

calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite

I just got my macbook 2.4 a week ago and the battery will now only charge to 99%.
What is the best way to use it to keep the battery in good condition. I am normally near a power source but I read that apple do not advise to use the macbook plugged in so that what I have been doing.
Should I calibrate the battery ?

I just received my new MacBook Pro. It's the 2.66 with Anti-Glare screen. When I started the mac first time, I noticed my battery condition is 'Replace Now'. Has anyone experienced the same thing before? I then used the new mac without power cord for about 4 hours(browsing and updating iTunes, no heavy use) before the battery became really low.

I've heard that if I don't disconnect the charger after my macbook is fully charged then the battery life and performance will get reduced and will be weaker.

I have a macbook pro. My machine won't wake up at all. Battery is being charged on regular basis. I have tired to hard boot but all i hear is sound of machine booting up and shutting down. Is there ant possible way I can get my display back on my machine? When i close the lid, the indictor light is blinking slowly but as soon as i open the lid cover screen is always black. For last 5 days I have tired to discharge the battery and charge again, attached a wired mouse to see if it might wake up my machine but with no luck.

When I bought the mac book pro I was impressed withthe 7 hours battery life, however I have found that when fully charged mine only has 3hours. Is this a fault or did I miss some kind of disclaimer?

It was working OK. I have put it aside for about 1 month during the holiday. Now, it can not be charged. It works on power adaper, the plug has bright green LED on, but always 0% battery. Looks like the power adapter is still working OK, battery issue?

"Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?"Someone answered, "I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.

Ever since owning the uMBP, I have kept the battery charged and monthly calibrate it to maintain a 100% battery health. But through this, the laptop limits its portability and it is sometimes extremely tedious to find a plug in order to use it. My question is: Is it really worth it to keep a good battery that will last overtime, or would you prefer simply purchasing a new battery when your old one dies? Also, how big of a difference does a healthy battery compare to a battery put through regular use?
