Battery randomly losing power...

So, my Apple power adapter started acting strange; I had to fidget with the part that goes into the computer to get it to light up, and most of the time it wouldn't stay lit long. I looked around on the website, and it seemed that it was, well, dying/the pin was damaged. I went and got a Macally adapter, and it worked fine for about a month, and then my computer lost power (while plugged in) all the way to zero and shut itself off. I managed to get it recharged with the old, mostly broken adapter. The Macally was fine for a while, and then my computer went to 0% again, but stayed on, using the power from the wall alone. The battery wouldn't recharge, went to X eventually. I reset the PMU, and it seems to be charging again (or at least it thinks it is... still at 0...), but I'm not really sure what caused this or if it will happen again. I've had the computer for a little over two years; is the battery maybe giving out? Even so, I can't figure out why it shut itself off the first time while plugged in via the Macally. Did the loss of power from the old adapter damage the battery in some way? Do I need a new one, or should I just rely on resetting the PMU whenever this happens again?

You might want to check on the health of your battery by going to "About this Mac">More Info>Power and see what it says about the health of your battery. But it does sound like it may be on its way out. I don't know if the faulty power adaptor was a problem other than it might not have been able to charge the battery properly.
This is the iBook forum, but I would expect the PowerBook to be similar to an iBook.
You might want to download "iStatPro" from the Apple site--it is a widget that makes it easy to keep track of the health of your battery.
Good luck!

IMac randomly losing power

My 2006 Intel CoreDuo iMac has started randomly losing power. Without warning it will just power off as if someone has switched the wall socket off.
I've managed to power it back up again about 4 times after which it just does it again.
Once power is lost the only way I can get it to work again is to keep taking the memory out, putting it back in, try to switch it on, take it out again, put it back in, try to switch it on again, etc. until randomly it works again!
I've tried resetting PRAM by unpluging everything leaving it 15 seconds and then nothing... I've also managed to do a CTRLCOMMAND+PR when it was working.
Now it's gone again
Anyone any idea what might be the problem here?
I have no AppleCare so the iMac is out of warranty and the internal DVD drive no longer burns properly either. Should I give up on this Mac and put the money towards a new iMac (with AppleCare this time!) or is it going to be worth trying to get it fixed. My thoughts are that the local Apple Service Centre might take ages to determine the problem and try various things and then might not even be able to fix it.
Could it be the logic board? Power supply?
How much is a new logic board and DVD burner?
Thanks,
Neil

There are a number of threads on the iMAC loosing power. Check these:

My iMAC was doing the same; it finally died and wouldn't power at all. The tech at the apple store stated they have seen a few bad power supply cables that are the cause of the issue.

Computer randomly losing power after being serviced

My computer was just recently serviced after the motherboard was apparently damaged (the hard drive could not be located within the computer). After getting it back, I began using it regularly again, being slightly more cautious. It hasn't been more than five days and already I'm having issues, this time with power. I'm not exactly sure what is going on, but all I know is that one minute I'll be playing a game or working on music, and the next minute the computer just dies. It takes it a bit to be able to be powered up again, but the lap isn't showing any signs of overheating. Is there anything that I can do to fix this without needing to send it in again? (I'd rather not be without it again for 3 weeks, but if it boils down to it I will send it in again.)

My ipod touch battery keeps losing power even when switched off

Why? What can I do? Change the battery?

I believe I have the information you're looking for, in return, please repond to the thread saying if it's useful or not.
The iPod Touch can lose battery under several conditions:
1. If the Touch is left in the USB cradle, disconnected, the wires can leech current, reducing charge.
2. Heat can significantly reduce a battery's charge, so keep your unit away from the sunlight or other heat.
3. Leaving your Touch with the wifi on will tax the battery, even if you're listening to tunes. Make sure the unit is completely disconnected and turned off.
In short, make sure your Touch has wifi completely turned off, keep its cool, and disconnect the Touch from the USB cable or cradle.

8330 keeps losing power and rebooting

my curve 8330 keeps losing power and rebooting, does anyone know how to fix this, tried cleaning battery terminals but did not work.

I also have a 8330 and it does the same thing. It randomly resets (like a master reset as it takes a long time to reboot) throughout the day. I am a Canadian user and talked to Bell who told me I had to send the phone in. I went to one of their stores and sent the phone away for 2 weeks. I received it yesterday as it was "repaired". I had it less then 24hrs and again it reset about 12 times during that time. I am also not able to activate Enterprise since the repair. My company exhausted it's options to help me set it up but they determined the is a hardware issue. So The problem is worse now. I have tried with and without media card and it doesn't change anything. I have waste days with Bell trying to resolve this issue as technical support on the phone confirms that it is a hardware problem. I have now had to take the phone back to Bell for repair again. I am shocked with Bells attitude concerning this problem as I have talked to numerous customer service managers that tell me that I have a contract with them to provide the "service". They don't seem to care that the hardware doesn't allow me access to their service. I am also amazed that they don't care that a customer has to waste time on tech support phone calls and traveling to their stores to ship the phone back to Blackberry. As well as my company that wasted time setting up my "loaner" phone then my regular phone after repair and then again a "loaner" phone when nothing was fixed. When does Blackberry get involved and make the customer happy? I am surprised that the cell phone providers can not issue a new phone when there is a hardware problem under warranty. I was told by Bell that Blackberry typically needs to see the phone 5-7 times before they will issue a new one.... This translates to the customer doing 10-14 trips to the store and a large amount of time setting the phone back up each time...
Unless something happens fast, my company is buying out my contract with Bell and I will be switching to a competitive smartphone. This is unfortunate as I like Blackberry but can not stand the support. (since I can only talk to Bell as Blackberry won't talk to me directly and only directs me to my cell provider)
Very Frustrating. But a hardware problem for sure.

IPhone 5 battery quickly losing charge after updating to ios 7.0.4

Just upgraded my iPhone 5 to the iOS 7 v and immediately started seeing the battery losing power. Has to be the upgrade. I old go evn 2 days before without recharging but now I have to recharge at least twice a day. What's up with this?

Yes. I seem to have fixed it, but not really. I erased all music from phone, and then manually managed a resynced eveything I wanted back on there. Interstingly, it didn't work the first two time and said (waiting to make changes) so I was freaking out. But the third time was the ticket and now we are good. Unfortunately, there is a bug, and until there is a real fix, my music that I have in itunes on my computer is not easy to get to the phone. It seems that many people have had the exact same issue since the updates. Hopefully it will fix itself in the next update. Thanks for help though.

As a novice computer user, I wonder why I'm often getting "white-out" (program/app I'm working in goes totally blank onscreen). If it makes a difference, I'm working 99% of the time on battery, not AC, power. What causes this?

As a novice computer user, I wonder why I'm often getting "white-out" (program/app/site I'm working in goes totally blank onscreen). This is when I'm Internet online. If it makes a difference, I'm working 99% of the time on battery, not AC, power. Some of the possibilities I'm guessing are: glitches in my Verizon FiOS Wi-Fi providership?; staying too long on a site that's waiting for me to finish and "Submit"?; computer hardware prob (yikes, I hope not! It's brand new). Any ideas out there?

When this 'white-out' occurs, is the display 100% white with no error message and no menu bar?
Does this occur when you are using Wi Fi or connected to the Internet via the Ethernet cable?
Ciao.

Randomly losing network connection over wireless

Shortly after installing the 10.4.5 software update, my G4 iBook with built-in Airport Extreme card has been losing connection with increasing frequency. Built-in Ethernet use is unaffected. I'm calling this problem thrash-and-drop.
1. When it's losing signal, processor activity goes through the roof. I had Activity Monitor running during a thrash-and-drop. kernel_task CPU consumption goes from under 1% before the event, to over 80% during the thrashing, and back under 1% after the thrashing stops. The activity is so bad the cursor can't be controlled: using the track pad sends the pointer all over the screen or nowhere at all.
2. This has been observed to occur with two different wireless base stations: A Linksys WRT54G and an older SMC 802.11b router. Either router is within 10 feet of the computer. Only one is running at a time. There are no other base stations in range.
3. Another iBook G4 (OS 10.3, Airport Extreme card (not built-in)), sitting next to it, shows no change and its wireless behavior is unaffected.
Initially, this seemed more likely to happen when Safari was loading Flash-heavy pages. And after thrashing and dropping a connection, it was able to reconnect after either a reboot or a five minute sleep. Currently, it can't connect to a base station for more than a minute. Most recently, it thrashed and dropped while I was selecting the base station to use. This is true regardless of the application running. In fact, it will thrash-and-drop when there are no user applications running at all, after a fresh reboot.
I've tried the following things to address the problem. None have affected the thrash-and-drop problem. Admittedly, most of this is random:
1. Back up and delete network preferences in /Library/Preferences/SystemConfiguration
2. Turn off IPv6 in System Preferences/Network
3. Back up and delete network preferences in ~/Library/Preferences (com.apple.NetInfoManager.plist and com.apple.NetworkUtility.plist)
Has anybody else seen this problem? I want to blame it on the 10.4.5 upgrade but I haven't seen anybody else complaining about 10.4.5 doing this to them. If there's something I can do to fix this in a software setting, I'd much prefer that to yet another roadtrip to the Apple store.
1.33 GHz G4 iBook Mac OS X (10.4.5)

Hi!
I have the same problem of randomly losing network connection over wireless, though mine is hardly related to surfing.
I have an external storage drive in which I use for backup of my stuff, and I access the drive via my modem, using the airport. Of late, I noticed that when copying files from my iBook to the external drive, the connection would suddenly drop before the transfer is completed. This began to occur with increasing frequency, particularly when transferring large files.
I have since abandoned wireless connection, and reverted to my trusty cable. Still, I admit that I'm really curious about the cause of the apparent lack of reliability with my wireless connection. Has it something to do with the airport?

Try searching for "external battery macbook pro retina" (without quotes). You should find at least three potential answers in the first two pages.
I can't give you a specific recommendation, because I haven't (yet) tried any of them.

Battery consumption in power supply operation

Hello there.
i have a Problem with my MacBook Pro 15 i5 using Windows 7 with Bootcamp:
If i start my Mac with Windows 7 ( Power Supply and FULL Battery ) and start play a game ( for 2 or 3 hours ) the Battery is almost empty (Windows Info: "Power Supply Operation - Battery charing - 15% left") after quitting this game. So my Macbook has a Battery consumption during power supply operation. Why my Macbook is using the Battery instead of Power Supply ?
If i use Mac OS i dont have this problem. Just with Windows 7.
Why the Battery is almost empty after playing a game although i used Power Supply ?
Any ideas ?
Thanks

no ideas ? i really need help !

Losing power/signal and no internet connectivity for WRT54G2-RM

Just installed router and using Motorola SB5101 cable modem and Comcast. Followed instructions and the router has lost losing power and needing restarts a few times. Have it installed by ethernet cable to my desktop, and using laptop (XP Pro Thinkpad P42). Cannot get internet connectivity and also loses wireless signal connection. I know there are a number of similar posted issues, and I am new to this forum. Any ideas?

Download and upgrade your router's firmware, reset and then re-configure it...
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Cannot lower Critical Battery Level in Power Options

I am wanting to adjust the Critical Battery Level in Power Options to something lower than the default 7% that HP has set. When I try to change the number, it will not save and it just magically jumps back to 7%. This means that my laptop will hibernate when the battery level reaches 7% and I cannot turn it back on unless I plug it into AC power. 7% equates to roughly 40 minutes of battery time and I find this setting way too conservative.
I have done some research on this issue and have found the following:
Some suggest that PC manufacturers will somehow lock this setting to an arbitrary minimum and the user cannot change it to anything below this minimum (it appears HP have set it at 7% in my instance).
This link suggests using power.cfg and the command line to make the changes How To Lower the Critical Battery Level to 1% in Windows 7
Steps I have taken to try and resolve this:
I have tried the powercfg.exe method described in the aforementioned link to change the critical battery level to 3% and initially it appears to work. When I open up the Power Options screen, it indeed says 3%. However, when I actually test it out by using the laptop, it will still automatically hibernate at 7% battery level - it simply ignores the 3% setting.
I have also tried using powercfg.exe to change the Critical Battery Action to "Do Nothing" and likewise this setting is ignored and the laptop hibernates anyway.
I have phoned HP support and the only useful information that I got from them so far, is that the PC manufacturer has set it to 7% and it cannot be changed. They said they will escalate this matter to the research team and give me a call back.
I phoned Microsoft support and the consultant seemed to be confident that he could fix the issue but would not divulge the answer because he said that doing so would void the HP warranty and he didn't want to be to one to do that. He suggested that I call HP and request a conference call with Microsoft and they could then fix it. He seemed to be of the belief that if HP has set the 7% minimum that they should be the one to remove the limit.
If nothing works, I wonder if completely formatting the laptop (including removing the HP recovery partition) and then reinstalling a different Windows 8.1 (or Windows 7) will let me have full customization of the Critical Battery Level?
I would really appreciate your thoughts on how to fix this. It really fustrates me that HP thinks they know better and that the user needs to have 7% battery reserved - it is such a waste not to be able to utilize a battery to its full potential.

Hi @Sparkles1 ,
There must be an alternative solution to this.
What is the reasoning behind HP locking this setting at 7% minimum? I understand that a battery should not be run down to 0% as this will damage the battery but 7% is unreasonably high and in fact this does not conform with ACPI standard specification. I refer to the following document: https://msdn.microsoft.com/en-us/library/windows/hardware/dn481320%28v=vs.85%29.aspx
In particular, please see the table where it says that the critical battery level must be set to a value between 0 and 5%
Can you please advise how to change this? I believe this is a software related issue (specifically, the battery drivers). Can you issue an alternative driver to install? If you insist that it cannot be done, I will have no other option than to return the laptop and request a full refund.

CDX-M30 losing power

I have a marine CDX-M30 marine stereo in my boat. If the stereo is not turned on for a month or so, it looses all the stations/time (as if it lost ground and/or power). This occurs on its own, IE I am NOT cranking the engine, lowering the voltage below 12 volts. As long as I turn on the radio at least once a month, even for a moment, there's no problem. I checked for any updates for the unit, there are none. This is the second unit, (the first one, same model) did it more often. West Marine replaced the unit with this one, it has only happened once since (I turn the radio on weekly).
The battery is a class 27 and is always on a charger. I have replaced the main line, also replaced with new connectors from the battery to the main console. The stereo two hot lines and ground are wired direct to a SS power distribution block under the console. All connections are spotless. There are no fuses inbetween the battery and the power distribution block. All accessories are fused after the block. Note: the time clock on the Yamaha gauge does NOT loose time.
I was told by Sony the memory is stored in the main head, not the removeable face plate.
Any idea's???????

I suggest you contact our Technical Support team for further assistance: http://esupport.sony.com/US/perl/contac ... mdl=CDXM30
