Bad battery or adapter?
So my computer has been telling me to replace the battery for a couple Weeks now,but after reading on the hp website that my laptop should work even without the battery in place while the adapter is plugged in..and mine does not,I am assuming I need a new adapter?
Then how are you charging the battery? What model is the laptop? Does a light come on somewhere on the laptop when you plug in the adapter? Does the Windows battery icon say "plugged in and charging"?

New iPod touch bad battery life? Already tried tips and support said nothing is wrong...
I just got a new ipod the other day because my 4th gen had a really bad battery(it was very old). When I tried my new one out, I noticed it was just as bad. I tried all the powers saving tips but unfortunately they do not work. I called apple yesterday and they said it was fine( they looked at the battery through the diagnostics thing I think). Anyone know what to do?
We'll, I don't know a full charge, but it was at about 80-90% yesterday when I took it off the charger. All I did was listen to iTunes Radio and use my snapchat on and off and I got the 20% warning in less than an hour

PowerBook G4 12" Damaged by Bad Battery?
I have a PowerBook G4 12" 1.5GHz with a bad battery that is about to be replaced by the Extension Program. Can the bad battery have damaged the computer while it was in use in the computer? In early 2005, I purchased a brand-new PowerBook G4 15" 1.67Ghz which turned out to have a bad battery, but because at that time the battery problem was either not yet known or not yet acknowledged by Apple, the battery was not only used in the 15", but when it was sent back from Apple after the first of three service attempts, the bad battery was not replaced and was sent back to me and I, not having been informed there was a battery problem of any kind, continued to use the computer until its hard drive then its logic board failed. Eventually, I found out about the exchange program by accident (and was officially informed by Apple one year later, in June 2006; ironically, the 15" had been replaced with one of the first MacBook Pros in March 2006). I include this history because I have always wondered if the bad battery damaged the 15"'s logic board. Now this 12", which I just bought, whose bad battery has been installed for years is having major issues: the screen freezes within the first 2 minutes of booting from disk, hard drive or network boot image (it has never booted to the desktop since I've owned it); it heats up under the hard drive/near the video chip; when TDM is attempted, the screen stays black altogether and the 12" never appears on the host's desktop. It will boot into Open Firmware but not in single user mode. There is some kind of white sticky substance present in small amounts around the pins thar lock the battery into the well. For the record, the 12" is otherwise in seeingly flawless condition with no dents or other signs of being dropped and inside it is clear no one has disassembled it or even removed the topcase. When the battery is removed and the AC power connected it still won't boot. Sorry this is so long.
The actual runtime of a battery depends on several factors, including what you are doing with your PowerBook. Information on stretching out your battery's runtime is available in this article. For a daily planner, try using iCal in the /Applications/ folder, or dTasks if iCal won't do what you want.

Can a bad battery affect my MBP's performance, even when plugged in?
Well, as the title says... my battery status says "Service Battery", and although I know the instructions are simple ("dude, take your laptop's battery for servicing!"), a few months ago my financial situation changed, I'm trying to adjust the budget as much as I can for now, and I'm not sure I can afford to spend much money at the moment.
The thing is, my laptop's performance has been slowly getting worse all the time. at first, it was only with resource-intensive applications, but lately, even having more than 5 tabs open in Chrome gets the system all laggy. Now, as I've read on other threads talking about batteries being in bad shape, I would assume that, if the system can't draw much power, it can't work as hard, so a bad battery could be the culprit of such performance. However, if my laptop's plugged in, shouldn't it be drawing power straight from the outlet, hence being able to get all the juice it needs to feed both the 9400M & 9600M GT?
Ah! by the way, the info I guess I shouldn't post this without: It's a Macbook Pro 5.3, purchased in March 2010. This is System Profiler's Power section info:

Hope someone can help... thank you so much in advance!Not necessarily, if the battery is trying gobble some power, as the bad batt is still in the charge/power circut. 446 cycles is quite a bit, and not a bad run, it also depends on how it has been used.
I would replace it ASAP as it is possible that it may create/cause more severe issues. A new battery is less $$ than more serious damage that could possibly result from leaving it in. -

i also check preferences....

i hope someone can enlighten me...
thanks in advance...
macbookpro Mac OS X (10.4.9)
macbookpro Mac OS X (10.4.9)your stats seem ok.. i've gotten it as high as 142 hours temporarily, when its discharging.. the battery time to die measurement is at best an estimate..
what were you running that you were drawing -1400 amps? thats a bit excessive...
i run a problem called IBatt2 it has a grading system which compares your battery to the median of the same type of system battery... it will also show you the essential data...
my battery with 45 cycles, gets a "C" grade on their system.

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

Powerbook alternates between battery and adapter when plugged in
The other day my PB started alternating between battery and adapter when plugged in: the symbol changes from batt to charging every few seconds, brightness goes up and down. I've managed to find a position where it will actually charge. I even tried a new adapter, but it's still extremely temperamental.
I'm afraid there's something wrong with the internal power jack, but is there anything else it could be? Any way to tweak the jack?
Thanks!No, there's no way to "adjust" the port. It's soldered to a small Sound/DC-In card inside the Powerbook. What's apparently happened to yours is that the cord has been jerked rougly up, down or sideways one time too many, and one or more of the solder joints has broken. Because it's now able to move, however slightly, the rest of the joints are also being stressed every time you connect or disconnect the cord. Sooner or later another will break, then another. You'll end up having to replace the card when you can no longer shim or jimmy the port so it makes proper contact.
If you're very good at very small-scale soldering, you could take the card out and try to repair it, but if you're an average ham-handed Joe like me, replacing the board is a better bet. Getting to it, while not actually difficult, is a pretty considerable adventure in an Albook, because nearly everything else has to be removed from the case first to reach it. -
Macbook Pro Bad battery better than none?
Hello!!
I know this might sound crazy but on yesterday my Macbook Pro (early 2008) battery expanded while connected to my mac. I didnt notice this until I powered it on and couldnt use my track pad. I thought maybe the mac had been stepped on or something. To make a long story short, I am a DJ and use my Macbook pro for that purpose. I have a gig coming real soon and I've read that the mac will only run at 1Ghz or so without the battery. I need my computer to run full speed as its needed for my DJ program. I cannot risk it lagging during a gig! I refuse to put the exploded battery in it and I'm sure Apple will do nothing about this outdated Mac. I ordered a non-working battery hoping to be able to use my Mac at full power until I can purchase a working battery. Will this work? I know your asking why order a bad battery? I couldnt order a working one and get it delivered by my gig date.
Thank you!BobRz wrote:
I'm not sure why no battery would slow things down, but I've never tried it. Again, why not just see what it does with no battery?
If the OSX senses that there is no battery present, it will throttle the CPU. This is to protect the Mac from those situations where electrical loads are such that the charger alone cannot handle them and the battery is used to supplement the charger.

I have a 4s runing 6.1.1 every 5minutes it promp me network lost and i have very bad battery issues lit draine so fast what should i do?
What have you figured out? Anything? What you show just shows a pretty quiet system except for firefox having a bunch of tabs open. You've got some page ins and outs so you maybe your'e hitting your HD with swap files more than what you think?
I think something like coconut battery app or something like it will tell you the charge cycles on the battery. How many do you have?
Lastly, are you using any extensions like ad blocker, or click to flash? -
Power Mac Desktop G3 Blue & White - Bad Battery?
Hello all - I just found you G3 guys here
I have this older G3 Blue & White 350 mhz loaded with OS 9.1, and I haven't powered it up for a number of years. When I went to power it up, the network clock was naturally out of wack. Got an error which said:
Network Time in error set for 1956. I reset the time and date several times, and although it works briefly, it won't keep accurate time. Is this indicative of a battery replacement? The battery is small and cylindrical - shaped like a camera battery - Not Flat.
Yes? And if so, is it any big deal to replace? Do I need to reset anything?
And another problem is that the power button periodically gets stuck. Sometimes it retracts, and sometimes it doesn't. Sometimes the machine is starting to boot, when it just cuts off. If I wait a while, it can eventually start and boot up completely but usually gives the bad time error message again. Is this a separate issue? Or could it be related to a bad battery, and bad time and date?
Thank you
MikeENIGMACODE,
Yes, the minature - 1/2 AA height - battery is the one to replace. Radio Shack sells them for $15 or you can shop on line and find some for half that.
If you have a power strip and all components are plugged in, when you turn off the power strip, you turn off the only source of power to keep you clock going. You can shut down the computer but not turn off the power strip and the clock will continue to work fine. My B&W has gone more than a year on a dead battery.
If you startup, set the clock, then hit restart, the correct time should be retained in memory because the power is not interupted. If it loses the time during that reset or restart, you have other issues.
The sticking power button is most likely misaligned plastic. Double check to make sure that it is not sticking. Then use the keyboard to turn on and off the computer. That will isolate the switch to see if the problems are related or not.

I haven't touched my Iphone 5c for an hour besides a few texts and it as dropped its battery life by 20% I also took it off the charger (at three in the morning) at 90% and woke up to a 70% battery life. I got this phone yesterday and let it die and recharge like you are supposed too, I think it is a bad battery but I am wondering as anyone else had this problem before? I want to know if I should be taking this back or not? Also while charging last night the phone got very hot which is also very concerning.

Ipod touch has bad battery and suddenly turns off
Ipod touch has bad battery and suddenly turns off but only works when its on a dock with speaker...
any advice on what to do, because i am thining of getting the battery replaceTry:
- iOS: Not responding or does not turn on
- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order. -

Does any one know if a bad battery can produce the sad iPod icon and the false-start whirr-click which is normally associated with a dead HDD when all of the recommended remedies have been exhausted?
I recently installed a new hard drive in a G4 ipod. It worked perfectly but after just a week during which it was not used, the iPod gave the same symptoms that I had associated with a dead HDD. I was able to use Disc Utility and iPod restore after leaving it plugged in for a day and then it updated in iTunes. When I disconnected it from the USB, it promptly failed again. Once more I managed to mount it in disc utility but it failed to format with an error message about a missing partition. It isn't recognised in ASP and just sits showing a static one-third charged battery icon.
Is it worth investing in a new battery. Any thoughts welcome, thanks
iMac 600 Mac OS X (10.3.9)Guess what? Having bought and installed a new battery, my G4 iPod has been resurrected. It seems that the sad iPod icon and the whirr-click can be caused by a faulty battery - even one that is not completely dead but presumably is not delivering the necessary power. Having replaced the HDD in my "dead" iPod and getting a working iPod for a short while I foolishly threw out the old HDD when perhaps there was nothing wrong with it, before my iPod died again. If you hear your iPod doing the whirr-click DO NOT assume your hard disk is broken, as I did. Even when connected through my firewire or usb ports the iPod would not respond in any way. As soon as I changed the battery I was able to restore it and update it as normal.
Another thought I had. Is it possible that simply disconnecting the battery in the iPod resets the firmware so resolving any errors due to corrupted data that isn't fixed by using the reset combination on the click wheel?
So MORAL of STORY: If you have a dead iPod (OUT OF WARRANTY) check the charging current and replace the battery ( a cheap option if you DIY ) before you replace the HDD.

So I just bought an iPhone 3g about 5 days ago and the battery life is horrible I get about 5 hours of usage and 12 hours of standby before its in the red and almost dead. Is this normal or do I have a bad battery. I use it mostly for texting and e mail. I have 3g, wifi, and bluetooth turned off. I sometimes use wifi. Also when it goes to sleep sometimes it shuts off my service so I don't know if Im receiving a call or text or email. Could someone please tell me if this is normal cause it sure sounds defective to me. Thanks!
The iPhone uses battery power per data collection set time.
If you have MobileMe or an inbox set with PUSH enabled or set to X minutes or 1 hour, each time the server is pinged orsing games and applications costs power.
If you are in an isolated area with "No Service", the iPhone uses even more power to boost the signal to receive calls.
The same goes for any normal cellphone service. If in an isolated area with "No Service" it costs the "even more power" issue.
Switch your iPhone to "Airplane Mode" or buy a home/car charger if you wish to keep your iPhone on as long as you want. This reserves your iPhone's battery power until you are ready to make phone calls or receive data.
