Battery loses power

Hi has any had problems with the battery losing power just after it has been fully charged. I try to search through songs and it tells me I need to re-charge it.

I've had my PB for a little over a year now, and I almost always let it sleep overnight. Up until recently, it would lose about 5% power overnight and I would leave it plugged in all day when I was at work. In the last couple weeks though, it has started losing more like 10-15% power overnight! I haven't made any major updates or anything.
I just read a couple things: number one, your PB should not be plugged in ALL the time. Number two, you should re-calibrate the battery "every few months" according to Apple. I have only calibrated my battery the initial time and one other time, about 4 months ago. So I think it's time to re-calibrate. I'll let y'all know if it helps!

Battery loses power as I watch

Has anyone else had the problem of the battery losing power quickly? I can watch the charge go out. This started after I downloaded the Bing Music app. I deleted the Bing Music app and still the battery is losing charge quickly. I cannot see any way to open the itouch to even have another battery put in. Thank you!

How old are your ipod touches? After a certain period of time your battery loses its ability to hold a charge. If it is pretty old you might want to consider enrolling in the battery replacement program through Apple or replacing it via a third-party site.

Battery loses power even when iBook closed

Hi,
As of late, even when I close my iBook and carry it around in my bag, the battery is running down. I have taken to shutting it off before I carry it, but this is not always convenient. Any ideas about what could be causing the problem/if there's a way to fix it? It does seem to latch shut (and go into sleep mode) when I close it.
Thanks!

Welcome to Apple Discussions!
You could try resetting the PMU and see if this helps:
Resetting the PowerBook and iBook Power Management Unit (PMU):

Also, you might want to check the health of your battery. (About this Mac>More Info>Power). If your battery has a lot of cycles on it, it could just be getting old and not holding a charge as well as it once did.
Good luck!

Battery Loses Power After Update

Since upgrading my software on my Iphone 5 with the most current update the battery only lasts 4 to 6 hours. Before the upgrade my phone lasted often 2 days without a charge. This phone is basically USELESS for business now. I'm so disappointed!!!

Capacity now dropped to 94%.... Do I need to calibrate again, did something went wrong in calibration? Or is my battery broken?

Lose power when remove AC but battery shows partial charge?

When i unplug my PB G4 it loses power and immediatly shuts off. However when it is on, it shows that the battery is 67% full. Is this a battery issue or something bigger.
Some other things i noticed also is that when in sleep mode i can umplug it without it shutting down. It only shuts down when i open it up. Also the battery seems never to charge. It slowly over time is going down. It started at 90+ percent and a month later is is at 67%. Also it never seems to be able to calculate how long the battery will last, it only shows the %.

Slate 500 loses power when undocked

I have a Slate 500 that loses power whenever it is removed from it's docking station. This began occuring after I used to HP supplied recovery disks to restore the tablet to it's original WIndows 7 Pro setting. I had installed WIndows 8 on the tablet but did not like the response time...however I was able to use it away from the docking station with a problem when WIndows 8 was installed. The problem started when I reverted back to WIndows 7. Am I missing a driver that activates the battery? I need help in resolving this. Thanks.

Hello Ahernandpr,
Your Slate 500 is a Business model. Your issue would be best answered on the HP Enterprise Business Community Forums
Good luck!

DV6 Notebook Battery cuts power randomly

My specific model is a dv6-6135dx, running Windows 7 Home Premium. I purchased the laptop back on 2011 and have so far only had to replace 3 components, the fan (burned out), the hard drive (picked up a nasty virus), and most recently, the battery (died). All happened long after warrenty expired.
Instead of replacing it with the same exact battery, I opted to upgrade to one that could hold a longer charge. The HP MU09 Long Life Notebook Battery.
My first problem: It sits very loose in my laptop, often falling out if I am not careful when moving my laptop. I've never had this issue with the old battery, but this is somewhat managable.
My second problem: Recently, when running on battery power, the power will randomly cut out.
I have ruled out overheating because this never happens when I am plugged in (and I have limited the max processor state to 50% on battery vs 100% plugged in).
I have also ruled out the possibility that I am moving the laptop and making the battery lose it's physical connection to the laptop because I have set it on a table and left it alone multiple times and it still cut power randomly.
When I power the system back on, the power level says it has the same amount of juice left in it that it had before it cut power.
The HP Battery check says the battery is OK, and the HP System Diagnostics Battery Test says PASSED.
What else can I do to troubleshoot or fix this issue?

Hi
You have a couple of options as I see it please update the Bios on the unit from our HP website.

New MBP 17 C2D - Machine loses power in sleep mode

Just got my machine so not a lot of usage, but I noticed it ran out of power yesterday. Charged overnight - it was in full charge at noon. Unplugged and used for a few minutes - put to sleep for an hour. Came back and it was at 92%. Used (lightly) for about an hour and battery went to 60%. Put machine to sleep, packed in suitcase and drove for 2.5 hours. Awoke machine and power down to 20%. Clearly either (1) it loses power in sleep or (2) it is waking up on its own and losing power. Only other thing I noticed is that I left parallels running internet explorer when machine put to sleep, and it had shut down (no message but app closed) when machine awoke.
thoughts

Try cycling the battery a couple of times by normal usage and see what happens. I remember this happening to me once as well when I first got my replacement MBP battery (due to the massive recall of Sony batts). After cycling the battery a couple of times by normal usage, it held its charge quite well I must say.

Zen Micro lose Power when Switched OFF??

Hello,
I was wondering if anyone else is experiencing the same problem as me. I fully charged my Zen Micro last night and then left it and just switch it on for the first time now (8 hours later), and the battery indicator shows 2 bars left?
Seems like the Zen Micro loses power even when switched off!?!
Can anyone confirm that this is the case and whether I can do anything to stop it from happening? Is this normal with Hard Dri've MP3 player or only with the Zen Micro?
Thanks.

<EDIT: (April st, 2005):<<FONT color=#330000>JazzMC has taken the initiati've and written a sort of FAQ and put together a website with all the information to date gathered in one place regarding this power drain of the Zen Micro while off (in standby). It's a great read for those who want more information about the subject and probably easier than wading through this thread.<FONT color=#330000>You can view the document by clicking here: <Zen Micro Power Loss<. <FONT color=#330000>Thanks JazzMC!
Ditto here. I did do a disk cleanup last week and the micro seems to be holding it's charge longer now. It's still draining the battery while sitting idle though according to the bar indicator, but slower (go figure?). This is my only real issue with the Zen Micro as I love it otherwise!
One wierd thing I noticed was I charged it full then left it sit for about 3 days (checking it off and on) then on day 3 it was at one bar. So I plugged it into my home sterio and turned it on to see how long it would play for. I was really surprised to see it last a few minutes shy of 9 hours...
Could this be a battery calibration thing instead of it just loosing charge? Like the meter misreads the batteries actual charge over time instead of it loosing power?
Donno it's wacky, please fix Creative!

Laptop loses power and won't boot

I have an Aspire V5-573G running Windows 10 Home 64bit, but I experienced the same problem while running Windows 8.1 Home 64bit.
I leave the PC on or off, come back a few hours later. The power indicator light don't shine if left off, shine orange if left on. The charging indicator lights blue if charging, else not.
I press the power button, both lights turn off and it does not boot.
I tried holding the power button down for 30 seconds, disconnect and reconnect the power adaptor, tap the power button, etc. The laptop seems dead.
I open up the laptop and disconnect the battery and reconnect it instantly. The laptop boots.
This issue repeats itself every time and it does not matter whether I have it connected to the power adaptor, leave it on or off, sleep mode or awake.
Since the lights do shine until I press the power button to wake/boot it up, I'm assuming it cease to respond once I do press the power button.
Help?

After additional tests I've noticed the following:
The hold-power-button-for-30-seconds trick works if, and only if, the battery is disconnected. When the laptop loses power as described in the original post, and the battery has been disconnected, I disconnect the power adaptor, hold the power button for 30 seconds, connect the adaptor and the laptop boots.
If the battery is connected, this trick does not work.

Windows 8.1 in Bootcamp on iMac27 - USB Joystick loses power?

I have a Saitek joystick I use for flying games. It works great on my ancient Dell XP machine.
However, having bought a 27" iMac last week, installed Windows 8.1 in Boot Camp on it - the joystick loses power after a minute when I'm in a game.
I'm not sure if the power even stays on the joystick long enough for a game (such as Battlefield 3) to see the controller.
It's USB.
Right now, the same USB port on the iMac is charging my iPhone just fine, sync too. So, the port is good and the joystick on another system is good - just don't know why the lights go out on the stick and it becomes "dead" as it were?

I would suspect the win8.1 driver more then I would tink bootcamp or the imac being the issue
usb in general should not require more then 5volts and 0.5Amp
you can try connecting a power usb hub (this is a device which have 1 connector it connects to the port on the computer and then have several ports you can connect other usb devices to)
if that also "loses" power then you know it's not a power issue but a driver issue
driver for the joystick or driver because you did not install the require apple drivers for windows made in bootcamp in osx

MOUSE Loses Power When SCROLL WHEEL is used, power back up when CLICK SCROLL WHEEL. FRUSTRATING.

Whenever I scroll using the scroll wheel with this Belkin USB MOUSE my mouse loses POWER and becomes unresponsive. It only regains power when the SCROLL WHEEL IS CLICKED. It works perfectly on other hardware so I know that it's this TOSHIBA LAPTOP or an UPDATE thatis the PROBLEM. I do NOT use the touchpad because they are inferior to mice when working with graphics. Is there some kind of conflict here? How do I PERMANENTLY disable the touchpad--it's completely and utterly useless to me compared to a mouse and just makes me angry and I really want to be able to use the scroll wheel on the MOUSE without it turning on and off and on and off and on and off. This is a very recent issue that hasn't plagued me until recently maybe within a week or two. Note when this happens it flips between the synaptics touchpad and the mouse for CURRENT SELECTED INPUT DEVICE, regardless of WHETHER OR NOT I have it set to disable touchpad when usb device is plugged in, so I don't need to try that step. Thanks!

I haven't heard of the scroll wheel issue anywhere else (mine is fine), but the blank picture issue is known.
Myself and many others have experienced it, definitely a software bug.

I downloaded the new 7 update and now my iPad won't charge to 100% and loses power even when not in use ?

i downloaded the new 7 update on my ipad. it now will not charge to 100% and loses power even when not in use. any solutions ??

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.
Then plug it in and let it fully charge.
