DV7 4080, unplugging ac adapter makes battery indicator say no battery

Brand new battery. Battery indicator says plugged in and charging while ac plugged in. When I unplug laptop goes to battery poower mode and will hibernate if indicator says battery inicated and ac unplugged. Sometimes when I unplug the indicator will go to battery undetected and ac plugged in indication. Have updated Bios

Hi,
First of all, shutdown the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for a full minute.
Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here. When the uninstall is complete, shut the PC down, unplug the AC Adapter, re-insert the battery and then start the PC on just the battery. Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shutdown the PC again. Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the issue at all.
I am waiting to hear back from you.

Iphone battery indicator says 100% but the icon is black not green

i have a iphone 5c. the battery indicator icon on top says 100% but the icon is a batter but its all black not green. is that right? should it be all green?

You need to make an appointment at the Apple Store Genius Bar to have it evaluated by the techs there. We are just users like you and cannot possibly diagnose what's wrong with your phone without looking at it.

In 'about this mac' the battery condition says 'check battery'. Should I be worried?

Hey guys,
I've been looking at replacing a few parts for my macbook as it is getting a little old and beaten up now, and I don't have the money to buy a new one at the moment. I have just been searching through everything to see if anything is wrong. Mine is a white macbook from late 2009. So far I've had the bottom case replaced because the rubber was starting to peel off and was very scratched.
Now I am looking at getting my trackpad replaced (or fixed) as it is stuck down and doesn't click anymore. I've tried cleaning it incase there was something stuck in it, but hasn't worked. After some research I've found that this could be due to a swollen battery. I had a quick look at it when I replaced the bottom case but it doesn't look like it has swollen. So I checked to see the conditon of the battery and it says 'check battery'. I am only up to charge cycle 299 and there is no problem with charging it or its charge life (not that I've noticed anyway). Could there be another reason as to why it says this?

Firstly the trackpad could easily be due to the trackpad screw not being at the correct depth, easily fixable especialy if the tap to click works.
As for the battery check battery usually means the battery has become faulty in some way. You could try an SMC reset with your adapter plugged in. (Shift-Option-Command-PowerButton at the same time). Your battery should still work but 299 is way too little for a your year MacBook needing to be replaced.

Hi everyone
I have a macbook pro retina disp 13inch. i have a problem that based on battery bar menu it says me that check battery. I havent see this situation before.

Battery checks say change battery, but it charges and works fine. Help?

Hey there,
Just having a problem with my Laptop battery. My product type is a HP G61 Notebook PC. The battery icon in the bottom left says the battery should be replaced, with checks saying it has reached the end of it's useful life.
I find this hard to believe since I've had the laptop a year and it still charges and works fine. I don't want to spend any unnecessary money at the moment so I'm not sure whether to wait and ignore it to see how it goes.
Suggestions?

I suggest that you perform a calibration of your battery.

Battery condition says "Check battery"

I have a MacBook Pro 2.33GHz Intel Core 2 Duo, and am now on my third battery, which is now only 12 months old. The nice people at the Apple Store gave it to me at no charge because my first two batteries had such short lives. Currently System Profiler says "Check battery" and that full charge capacity is only 3368 mAh after only 43 cycles.
Why do these batteries not last well? Dying after only 43 cycles? I need to return to the Apple Store for a fourth battery?

Hi Mactrix,
I did try that, and unfortunately, without warning, the machine shut off as I was sending mail and Mail got corrupted. I've calibrated the battery before, and always got a pop up that warned me that the machine is now running on reserve power. After the "reserve" ran out, it would sleep. But this time there was nothing, just a "click" and darkness.
Took the machine to the Apple store, they hooked up an iPod nano running a battey test program which said the battery was bad, Because the people there are so nice, they gave me a new battery (because it had so few cycles on it). No wonder Apple support is rated so high.
Fortunately, I could restore Mail from TimeMachine - although there are some quirks I'm working on.

Recently replaced my battery - already says 'Service Battery'. Help?

I recently replaced my battery as my old battery had swollen and was adviced to replace it. I have had my new battery for about less than a week and it is now telling me to replace the battery. (3 Battery loadcycles)
Anyone else had this problem, or know how to fix it?
Thanks.

Try to get a refund from the 3rd party, hopefull it did not cause any damage, then have an authentic Apple battery installed, by an authorized installer, so that you have a warrranty.
That is why most folks asay to go to Apple for this, as it is less costly in the long run.
Best of luck

Battery indicator says i have 300 hours left..

sometimes...when i restart (because of Onyx) and when Mac os x resumes...it says that i have 300 or more hours left on my battery (one time it said 1064)...then it goes back to the normal 3+ hours... so i was wondering if this could indicate a problem...
also, how long does a normal charge from, say, 25% take? cause i plugged it in...put it to sleep...was away for probably 45 min. to an hour and i came back to it and it says that it still has an hour left till it is fully charged...
Any input is greatly appreciated!

RE the 300+ hours, I have seen this too. It's not a problem, so don't worry about it. (I suspect it has to do with what's going on at the exact instant that the OS interrogates the battery for it's current charge capacity.)
RE how long to charge, depends on how discharged it is, but 3-4 hours from ~25% is not unusual. The battery charges up to around 80% fairly fast, then trickle charges the remaining amount, which is better for battery longevity. Same reason your MBP will not try to charge the battery if the current charge is 95% or higher - prevents overcharging (which shortens battery longevity).
Hope this helps...

Battery indicator problem!

I have a nokia x6 and i have a problem. The battery indicator shows full battery until 30% left. (i used bettery monitor application.) and ther rest of the battery indicator lines dissapear very quickly. It happens in my E72 and 5320 xpressmusic too. What can i do for a more precise battery information?

The standard battery indicator is never going very accurate. However, you can try to make it a little more accurate by occassionally allowing the battery to run down and only charge when it beeps low battery. There is no need to wait for the phone to turn off as this could lead to other problems.

Is the battery indicator misleading??

Hi all,
I just got the new iPod 30GB and I notice that right after it's been fully charged, when I just listen to music, within 10-15minutes the battery indicator goes from full to 3/4. It seems like the battery indicator shows the battery is getting less and less power. Do I have a defective iPod, or is this just the nature of the beast. I haven't let go all the way to the end, so I can't say whether it is actually losing it's charge, but the indicator appears that the battery is running out faster than what I'm used to with my old iPod. 10-15 minutes and the indicator going from full to 3/4 quarters seems a but fast right??
Is anyone else running into this problem? I am not playing much video on it, so it's generally playing music, but I hear the video playback uses alot more power and that battery runs out faster in that case. This would probably not apply in my case, as I took this under consideration when monitoring the issue.
Just would like to know whether this is just a display or software bug and I don't have to worry about the actual battery life running out...OR if I really do have a battery issue, I should run this back right away....
Your advisement is greatly appreciated.

So I decided to fully charge the iPod, then run the stop watch and continously play music while timing the battery life. It's been six hours so far, and the battery indicator shows a spec of red, but totally empty. It's still going though. I'll let you know of the progress. It sounds to me though that this is a combination of a battery indicator light innacuracy, and having to charge and run the battery completely down a few times to get the battery working at good capacity. I haven't ran the battery all the way down yet, so this test would be the first time. I'll try and run this test with the stop watch on, a couple of times too and see if the battery life improves. I'm at 6 hours so far, and have not played any video, so according to Apple, I'm supposed to get up to 14 hours of continuous music, so we'll see how far it goes.
At least I'm not the only one, so I'm thinking this is just the nature of the beast as opposed to a defective product. But try out the test I'm doing, and see what comes up. What does your battery life truly go to......

¿Problems with battery indicator?

Hi guys of apple community I have a problem and I would like to give me tips to solve the problem
The problem is that the battery indicator on my ipod touch 4G has a strange behavior while charging indicator shows the battery charged (but the battery is not fully charged) and there are times when the battery indicator indicates the battery is still loading (but I know that the battery is fully charged) This is not a problem that really affects me because the battery works fine I am concerned to know why these problems happen if something serious I have no guarantee to bring the ipod touch to repair
Could you tell me if this is normal or if it is really a bad thing? I tried several power adapters and multiple computers but the problem is not resolved
I have firmware 4.3.5 with no jailbreak
P.D:Sorry for the bad english but im mexican and i dont know very well the english
Thank You!!!

I just bought my mac, yesterday. why is it already saying "service battery"?

Of course, new should mean new...I would be more than a little annoyed if mine failed right out of the box.
But the other side of it, if they thoroughly test it and only the battery is bad, you have a machine that has actually undergone more testing than they get off the production line...as the battery failure clearly shows
One side of me hates a failed item, other side likes a fully tested and passed item.
To me it wouldn't really matter what they did to test it. I would simply want either a new unit, in a sealed box just like all MBPs come, or my money back.
I wouldn't want it taken apart, repaired, tested, nothing. That is for them to do after I have left the store with what I original bought, A New Macbook Pro that works as it is supposed to without bad parts.
I really don't understand why that is not acceptable and that I or anyone else should accept anything else.
I also don't understand why anyone would even suggest that it be repaired as it is one day old and this problem was apparent right out of the box.
If they said to me "Well we checked it out and it's just the battery and we will replace that". I'd say "fine I would like to return it on the 14 day full money back policy". Thank you and walk out of that store.

Powerbook G4 Dies when unplug AC Adapter Even with fully charged battery

Powerbook G4 dies when running and unplug AC adapter even though have new battery and shows fully 100% charged. Also when shutdown, won't fully start without AC adapter being plugged in. When in sleep mode then can unplug power adapter and be able to wake and run on battery. Have tried resetting power management unit with no success

Hi, Alan, and welcome to Apple Discussions. Some questions for you:
What does System Profiler have to say about your fully-charged new battery's full charge capacity and current capacity?
Have you tested your internal backup battery?
How long can you ordinarily run the Powerbook on a full battery charge, if you unplug the adapter while it's sleeping?
Have you tested the Powerbook using a different, known-good AC adapter to see whether that makes any difference in the PB's behavior when you unplug it?
Is your adapter's plug deformed in any way?
Is the DC-In port on the Powerbook wobbly, i.e. does it move noticeably if you gently push sideways or up and down on the adapter plug when it's connected to the port?
