New External Battery/Sleep Issues

I have a weird one that I can't figure out. I have been using a new external battery for about a week (the old one wouldn't stay charged for more than an hour). Today my computer kept putting itself to sleep (sleep light flashing and nothing else working - not even power button) and not starting up again unless I unlugged it from the wall, took out the battery and then reset the PMU. I took out the new battery and put in my old one and so far so good. I wonder if it really is the new battery causing these issues or not. Any thoughts?

I'm having this same random sleep issue too!! It's been happening to me a little after I installed Leopard - but I'm not implying that Leopard is causing the issue. My PowerBook still has the original battery. The battery has not shown any indication that it refuses to accept a charge, nor is there any physical damage to the battery or the connectors.
*I have found an easy way to wake the computer when it does go into sleep.* I used to take out the battery, unplug the power cord if it was plugged in, press the power button and reset PRAM just as an added measure. But when you see it is starting to put itself to sleep, let it do its thing... don't try to stop it. When the white sleep light finally starts glowing, tap the space bar (probably any key will do) just ONCE. Sometime it will bring it back for a second and go right back to sleep mode, in which case I just repeat the steps above. Sometimes it'll last me a few minutes. If it does this repeatedly, then after pressing the space bar (after the sleep light starts glowing), I have noticed a delay in it waking up...I can press the space bar and it will either come back right away, or it may take like 30 seconds until it responds. Through trial and error, I've found that if I press any key more than once, I run the risk of it not coming out of sleep mode period....then I have to go through the whole reset process with the PRAM and all.
Hope maybe that helps someone
Has anyone kind of figured out what this could be the cause of? My laptop gets kind of hot sometimes, but it doesn't always force itself into sleep mode when its hot - so it may or may not be a over heating issue perhaps?

Macbook Pro and external monitor sleep issues.

I recently upgraded to a new 13 inch MacBook Pro to replace my previous one. With the upgrade, I'm now on the latest OS and I have a Thunderbolt instead of Mini-displayport output. I have a Dell U2410 monitor which has worked great up until now, but I now have the following behavior:
When the laptop sleeps (or puts the display to sleep) the monitor begins to turn on and off. It goes to powersave mode and immediately wakes up, realizes there's no signal, and goes back to powersave mode, etc etc etc.
When I wake the computer up from sleep, the monitor's behavior stays the same. The laptop never detects the display and begins sending a signal.
If I unplug and replug the adapter, all is well.
There seem to be two separate issues: whatever signal the computer continues to send down the display cable after sleep seems to confuse my monitor, secondly, the computer never again sends a real video signal down the line after it wakes up.
I'm on the latest 10.8.3. My adapter is the same adapter I have been using for years, an apple mini-display port to DVI adapter. Supposedly this adapter is still compatible with the Thunderbolt port.
I've seen lots of issues online about wake up issues with the latest OS. Is there a workaround for this yet or do I have to uplug my monitor anytime I sleep the computer?

Hi Steve,
I have had the exact same issues after adding a WD Thunderbolt Duo external drive to a Mid 2011 iMac and then daisy chaining the Dell U2410 monitor off that.
My Mini DP to DVI cable ceased working properly - sleeps issues.
After buying one of these adapters of Ebay:
http://www.ebay.com.au/itm/3-in-1-Mini-Displayport-to-HDMI-with-audio-DVI-DP-ada pter-3in1-convertor-Macbook-/110861703462?pt=US_Audio_Cables_Adapters&hash=item1 9cfdf5926
I then tried all the different cables that came originally with the Dell U2410 with that adapter, and none of then would put the U2410 to sleep properly. The backlight would stay on, or "No Displayport Cable" would float around the Dell display with the backlighting still on. Or otherwise the Dell would try to go to sleep and then wake up again and cycle like you found.
Apples Mini DP to VGA adapter was sleep successful with the VGA cable (Analogue) but the output picture was not as sharp as DVI or Displayport, plus there was RF interference with the cable.
After lots of internet searching I have found a near perfect solution:
A HDMI to DVI cable with the HDMI end connected to the Ebay 3 in 1 adapter, which then connects to the Thunderbolt port.
Connect this to DVI-D 1 on the Dell U2410.
On the Dell in Menu - Other Settings, disable DDC/CI
Now in OSX Settings - energy Saver you will have to tick:
"Put Hard Disks to sleep where possible" and select a short time frame for "Computer Sleep"
I have found that the display would go black but the backlighting on the Dell U2410 would stay on, when the display went to sleep on the Mac as per the Energy Saver "Display Sleep" setting.
The backlighting on the Dell would only turn off when the time for 'Computer Sleep" has elapsed and the external Thunderbolt hard disk went to sleep as well.
The Dell U2410 would then wake up correctly as well when my iMac woke, with this setup.
Cheapest solution for you would be to try an Apple or Ebay HDMI to DVI adapter and then use the DVI - DVI cable that came with the Dell.
If that fails get the 3 in one Adapter and use my Mini DP/Thunderbolt to Ebay Adapter to DVI-DVI cable setup.
I'm assuming your new Macbook Pro comes with the HDMI port ?
I believe the Sleep Issues with this monitor are all related to appropriate signal on the cable, and only the HDMI to DVI solution will work correctly on Mac's connected to the Dell U2410.
Good Luck. :-)

New MBP boot/sleep issues

I have a new 15" MBP and it occasionally has issues booting where it will get to the gray Apple screen and the spinning circle will freeze. Also when it has been asleep for a while (1+ hour) it will almost always freeze when trying to wakeup. If I force it to sleep or close the lid and immediately revive it, it always works. Is there anything I can try to do to diagnose the issue? I took it to the Apple store and they ran a drive repair and we couldn't reproduce the issue. It did it again on the first boot once I got home.
Thanks in advance.

External drive sleep issues with AEBS.....

I have a WD My Passport Studio drive, which works fine when I plug it into the USB port of my router to access over the wireless network (Apple Airport Extreme). It takes power directly from the USB port. No problems whatsoever.
If I plug my WD My Book Studio II drive (which is a 3.5" so has its own external power) into the USB port on the same router, I can access it over the wireless fine. But after a while of non-use it goes to sleep. Waking it up from sleep over the wireless connection then takes so long that I need to just unplug it and plug it back into the USB port again!
Is there any way I can stop it from going into its power save / sleep mode when used with the AEBS?

When I check my e-mail with my iPhone in the morning, there are no messages there, because when I wake up the Mini the next morning, it has already downloaded messages I received overnight. I can tell the computer was not actually awake, because no Time Machine backups had been done since I put it to sleep the night before.
I found other threads referring to Lacie drives not spinning down, so I'm assuming that's a problem with the drive, not with Lion trying to access the drive while the computer is asleep.

T440s External Battery not Charging

Hello there,
I have about a week ago bought a Lenovo T440s from a 3rd party seller. Contrary to what was stated in the manual, the external battery was already plugged in when I opened the box. The first thing I did was to charge the computer before turning it on. The external battery has not been charging at all now for over week, despite my best efforts. I have tried the fix of Deactivating the battery drivers etc, yet it doesn't seem to have worked. Has anyone experienced something similar and can tell me what the problem is? Is it the battery or computer? And is there any way it can be fixed without sending it back to the shop?

The old sleep issue

My iMac does not want to go to sleep by itself anymore. In the days of old one of the culprits was iPhoto. In my case, could it be Skype running? Or is it the USB camera (Logitech Ultra Vision)? Or does it have to do with the fact that there are other Macs on the network? Or is it the latest version of DiskWarrior (4.1)? what's new on the sleep issue?
Regards,
Jurgen

Stop! Not that easy. I plugged all peripherals in again, started uploading to Rapidshare....and went to bed. This morning, the fans were blurring, the screen was black...no sleep all night for the iMac. Turned out to be a kernel panic. I am presently testing the memory using memtest. After the first iteration, the memory was still deemed ok (I had previous memory failure but memtest discovered those within a few minutes). So, it must have been the peripherals...usb drives and/or webcam. The strange thing is: none of them were switched on.
I am at a loss....and my Apple Care expires in three weeks. Will have to monitor hardware and bring it in for a check if the panics continue.

The Best External Battery for 5th Gen iPod

I read something a while back about a new external battery for the iPod that gets ridiculous results. Im talking about 80 worth of music playback and 20 hours of video. But I cant remember the name of it. Does anyone else know which one Im talking about?
KT

There are tons of different external battery packs, systems and do it yourself solutions out there for iPods as well as generic USB devices. So unless you know something more specific about the one you saw, I doubt any of us can pin point it with "external" and lots of power, as most of them boost this stuff.
Do a web search and you will likely find many more candidates.

Battery and Sleep issues. Is this "normal"?

Hey guys, ever since day 1 My new MBP has been experiencing the sleep issue where in sleep the battery would lose about 1-2%/hour. I would go to sleep with the battery at 100%, and wake up to only about 87%. Also, when it was new the battery had about 4650 for full charge capacity, now its showing only 4540 after 10 cycles!!! Is this normal? Please help my MBP is less than 2 weeks old I have owned the previous MBP model, and the battery life during sleep was considerably better than this, and also it took less time to charge the battery!
Charge Information:
Charge remaining (mAh): 3463
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 4540
Health Information:
Cycle count: 10
Condition: Good
Battery Installed: Yes
Amperage (mA): 881
Voltage (mV): 12070
*I have also just updated the upgrade to 10.5.6. Will update and report if this will help with the sleep/battery issue.
Thanks for your help!

Reset the SMC (System Management Controller) and re-calibrate the Battery then see how it behaves ...

New MBA Sleeping Issues

I have a brand new 13" MBA and several times now have come back to a closed (clamshelled) computer with it dead or extremely hot in my backpack after several hours. It's not properly sleeping.
Most of the threads about sleep issues are related to external monitors. I don't use one. I turned off the setting for Bluetooth waking the computer. I don't know where else to look.
Any thoughts?

Test after each of the following steps that you haven’t already tried:
Step 1
Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer will not sleep if Internet Sharing is enabled.
Step 2
From the menu bar, select
 ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
 ▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 4
Reset the SMC.
Step 5
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 6
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 7
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

New External DVD Issues

New Computer: HP Envy m6 Notebook PC
New External DVD Drive: LG SP60
System: Windows 8
Issue: I place a DVD movie into external drive and there is no "auto play" function and no queue for me to start or play the DVD movie.
I have properly installed the external drive. I have used the drive to install other items including my printer. So it is not a mechanical or core function issue with the drive.
I was "forced" to download Cyberlink Media Suite; however, there is no button or queue to click to watch the DVD in the drive. All items are related to burning a DVD.
I have tried several other DVDs that are in excellent condition on a totally separate device. So I know it is not a DVD issue.
In the "my computer" it shows that there is a movie but it also shows that there are 3 main files, all with additional subfiles. None look like they are "clickable" to play the movie.
I am searching for a simple one to two click process to play a DVD--not a process that requires several subscreen maneuvers.
Windows Media Player does not recognize the DVD movie either.
Help please . . . .

Hi,
I would not allow external USB devices to run Auto Play because virus can come in to play. For Windows 8, WMP is not a good product to play DVD. The DVD Player on CyberLink suite should play DVD's for you. You can also use a free product called vlc, which can play nearly all video formats.

Mac book pro 10.5.7 sleep issue..... not even sydney genius bar can help me

ok hey guys, this is my first ever post on a support forum so please help me out!
I'll give any specific hardware info if needed later on but this is the basics:
i have had my mbp for over a year and 6months into it my mbp started going into sleep mode for no reason ...and no im not simple the energy settings are set to never sleep so its not that. Since then i have tried and tested everything under the sun to resolve the issue i have been to the genius bar and booked it in several times, each time they tell me they can not find any problem. I have had the logic board replaced - i have tried removing the p.list files, resetting pram thingy the battery test thing....everything...i have looked on endless forums for a resolution but nothing works!, it will go to sleep at random times generally when im doing alot of things on it it can run fine for days maybe sometime weeks but then its starts playing up again. When it does sleep the screen goes blank and the power light pulses but worst it cuts the internet connection which is terrible coz i have a time capsule and it cuts that link as well and messes that up entirely! sometimes it will just keep cutting out every 20-40 seconds untill i wake it by tapping the space bar or moving my mouse sometimes it just shuts down completely - i have done a compete erase & reinstall but ill b honest i still reinstalled some programs from my backups that cant be downloaded anymore (isquint etc) coz the genius guys said maybe a program is corrupting the hardware but if anyone has any ANY ideas or has the same problem please! tell me - im sure i could add more info n stuff but if u want 2 ask me specifics then i will answer anything to help
thanx again guys.
i should say at this point the only relief im getting to stop it from sleeping is if i disconnect the power adapter and use the battery that seems to stop it, but it has crashed(slept) on battery power as well but as of today doing this seems to help ....hasn't crashed since writting this! LOL

Has anyone got any assumptions on suspect software that may cause my problem??
I see that louie has a possible response for you. I had forgotten about that problem.
lastfm, transmission or handbrake. Can anyone confim issues after installing these apps?
if not these softwares then im convinced im dealing with a power issue.
I would be doubtful (although not completely dismissive) of anything like these being the source of your problem.
the genius bar has said it may b an enviromental issue. this also may be the case, tho not so much recently. They said perhaps magnectic fields may cause it 2 go 2 sleep and its true moving my MBP around does seem to settle it for instance if i move it out of my room im yet to see any of my sleep issues occur
The movement sensor might be involved, as also louie's excellent suggestion of the temp sensor. It is difficult to know how to test these effectively and might need more tools than the GB can muster.
But i dont live in a electricity tower and i did move my MBP to the other side of my room where it worked for a good month - and then started again with the sparatic sleeping.
It is hard to disprove a negative. The only way to bring some sort of evidence to the table if there were some such interference would be to use the computer for an extended period away from where you are using it now. If it works without problem in (say) Starbucks or some other neutral area, and then fails within a few minutes of returning to your home, then there is something stronger to work with. Then you can start to track down some external source, I would guess.
So i will try a safe start as graham had suggetsed as this seems as a simple enough fix - but i do run a time capsule, ext 1TB HD, Wireless mouse etc ..which i presume will not work in safe mode .... and is the idea to just keep safe mode on untill it does crash again or will just starting up on safe mode then restarting solve the issue?
Time Machine ought to work in Safe Mode; and I would not suggest working that way for a lengthy period of time: just to start it up perhaps to clear something that is interfering. But what you write here is of interest: (A) The HD -- what is it (brand, etc, and how formatted) and how connected; plus the wireless mouse? What brand is that (and I presume you mean Bluetooth)?
As for A weak diode..I dunno what that is or how 2 check it
Right. I couldn't either, and most shops won't: they would just replace the board. There is a shop here . . . but that is too far for you.
i think the battery is ok ..as i said it performs better at this point when i disconnect the power...but not always... i had a terrible day yesterday when it would keep going to sleep everytime i reconnected the power, if i try 2 persist it will keep going back 2 sleep ever 30 seconds untill i eaither just leave it be for a while or untill it just turns off completely!
That suggests, as I mentioned earlier, something awry with the battery/power combination; especially if the performance is not consistent. A battery should deteriorate gradually, not come and go.
If it does turn off when i turn it back on it wont even get to the grey apple logo it just keeps turning off after 2-5 seconds (turning off not sleeping)
so im at a loss why that is!
No power. You have to wait a while until the power level is brought up to a workable level.
The power cord seems fine all the pins spring out - the middle spring is smaller than the others tho.
Mine too. That seems OK.
Do post those logs. Someone might see the answer.

Battery life issues on iphone 5 with ios 6.1.4

I had upgraded the OS on my iphone 5 to iOS 6.1.4 and now I am facing extraordinary battery drain. I left my phone at 35% battery life while going to sleep and when i wake up, after 8 hours, it has gone down to 8% and less. This was not the case before with the earlier version of iOS or my iphone 3gs. I have tried some tips and suggestions but I dont think those are really helping. Could someone please help me out as to what should be done in this case.
Hope Apple is listening and intend to do something. My phone is brand new and not even a month old.

No i do not have LTE network access at home.
My cellular reception is quite good at home as well as work.
Yes i am using an exchange account, gmail.
This is what i have tried..
turning off SIRI, auto adjust brightness, push messages, notifications, blah blah blah...
Seeems like deleting and adding the mail account once again helped, as i am experiencing a better battery life today. I had read about this somewhere but weired that this could be a solution to a battery drain issue.
But still I am planning to take the phone to a store to get its battery checked.

Iphone 4s IOS 7.0.4 update battery drain issues

I hope this gets to apple in regards to the issue of the battery drain. I have been following several discussions for the past couple of weeks and everyone seems to have some type of idea on what the problem is. I'm not a service tech or gadget know all, but I have been performing several "Nonscientific" test to see what is draining my battery.
I have a 4s that has always had good battery life. It seemed to run consistent to what was detailed in the product specs. I would only need to charge it every other day on limited use or the next day with heavy use. After updating to the latest update (IOS 7.0.4), the battery would drain in less than a day on limited use which is a couple of text, couple of email checks, 3 to 4 phone calls at less than 10 minutes each - no internet searches or game play.
So, after reading everyones suggestions in the forums and trying them, the battery still drained just as fast, if not faster. I read a post somewhere regarding “Bluetooth” constantly searching. So, I saw mine was doing the same. Someone replied to that person that it should not be the issue, as it does not use much power to run its task. (I found they were wrong)
Here is my nonscientific test, but a good one. (for the record I had nothing on in the notification center, Do not disturb off, only thing on in Privacy - location services was google maps, Siri, Yelp, and Find my phone; iCcloud was off; background app refreash was off; email fetch data was off; everything else was off)
Day 1 - I fully charged my phone several hours, I unplugged it at night before going to bed, did a hard reset to make sure every app was off, and only opened the settings app and made sure the Bluetooth was onand searching. I checked my phone 6 hours later and saw the battery drained from 100% to 56% with no usage other than just being on and in sleep mode. That would mean it drained at 7.3333 % an hour. Some would say that acceptable. - Its not when there is no usage. The battery would die in 13 hours with no usage.
Day 2 - I repeated the test (as above), but turned off the bluetooth. I checked my phone 6 hours later and saw the battery did not drain at all. I started with a 100% and battery was still at a 100% with no usage other than just being on and in sleep mode. I opened a couple of apps and closed them to prevent them from running in the back ground and noticed I lost about 2% of charge after usinging it checking an app or 2. I put it back to sleep mode and checked it again in an hour and saw it only drained 3% down to 97%. Very acceptible.
Day 3 - I repeated the test, but during regular day hours with limited use of the phone (with bluetooth off). I was back to getting close to a normal battery drain I was experiencing prior to the update. I know that IOS 7.0.4 uses a little more battery power to run as it has different features and abilities, so the battery drain was not like it was before, but a lot better.
So, my experiment concluded to me that the new update is causing the bluetooth searching to run in the back ground continuously and causing the battery to drain unacceptably fast on my phone. This is a program issue that can be fixed by Apple. I find it unacceptable to have to control my bluetooth manually, as I never had to do it before and I shouldn't have to do it now. I hope Apple will fix it soon. I‘ve been a apple product person for years, and enjoy the products, but lately they have been not been satisfactory in the phone business. I have been playing with a samsung galaxy thats looking very promising, if apple doesn’t fix the issue everyone is having, they will loose business to competitors.
Please fix the issue!

Hi Folks,
iPhone & iPad2 battery drain issue SOLVED!!!!!
I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......
Devices;     16GB iPhone 4 with IOS6
                  16GB iPhone 4S with iOS7.06
                  32G iPad2 with iOS7.04
On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).
I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......
Hopefully this will be useful to others in this thread ..........

IPAD 3 battery charging issues

iPAD 3 battery charging issues. Read most of the discussions. My question is: If I take my iPAD to Apple Genius bar - what's the test they do to qualify for a replacement (do they place it on a charge and see the charge for Y% for X minutes or do they have other methods)

We're iPad users like you, so don't know.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

Problems after new New Power battery

Just installed a new high capacity New Power battery in my G4 1.42 GHz. I did the PMU reset, and battery calibration as recommended by New Power.
However, now, instead of going into sleep mode when battery runs down, the computer turns off. This happens when the battery gets down to around 15 minutes on the menu bar.
I don't mind (at least not too much) the computer turning off before the minute counter gets down to the end, but not going into sleep mode is a problem, as I lose whatever I'm working on.
This problem has probably been covered on this board, but I haven't been able to find it.
Any help is appreciated.
Ed

Same problem! Does your battery icon in the menu bar go red at about one hour run time left? What about the Amperage number in the About this Mac - is it a negative number?
See both my posts:

and
http://discussions.apple.com/message.jspa?messageID=8266683#8266683
I too can live with this, just wondering if you are having the same issues I am.
Have you spoken with any of the technicians? They told me someone with a G4 just called with the same issues, was it you?
