HELP!! wierd power issue.

Help! i have searched everywhere for a solution.
I have a hp dv7 1200cto noteboook pc. I have been having an issue with the battery constantly charging. My old battery died and wont really hold a charge anymore. I bought a new battery off ebay and it is constantly charging. it will hit between 95 and 100 percent but the light will stay on for days if i let it. I thought the battery was defective and i sent it back to the seller. the second one is doing the same exact thing. then i remembered the HP genuine battery was having the same symptoms before it died and i just thought it was because the battery was bad, but in reality this issue is what ruined the genuine HP battery which wasnt really that old. So now i have a new battery and its doing the same thing. I tried updating the BIOS and that didnt help and i cant figure out what the issue is. the hp battery check said both batterys were fine. could it be the AC adapter or is my motherboard no good? i really need help because this is really irratating! thank you!

Hi,
You can try resetting the bios manually(not from the bios options), the bios initializes all the devices connected to it at startup, maybe the bios is assuming that there is no battery present, in order to get it to its original state we need to reset it manually. I have posted a link to that guides the disassembly of DV7, disassemble the laptop including all devices connected to it in the order mentioned. Remove the CMOS battery and wait for a few mins for reset to complete, then assemble the laptop in the same manner as disassembled and switch the laptop on, you will be prompted to set the bios settings and now it should charge the battery without any problem.

Please help Ipod power issues!

My Ipod is little over a year old and just wont turn on all of a sudden. I have tried the 5 basic troubleshooting steps. I currently have it charging via the computer. Itunes does not recognize the Ipod is connected at all and it makes a strange quiet humming/vibrating sound. Is the dang thing dead?

Try doing a reset on the iPod again to be sure.
Slide the hold switch from OFF to ON back to OFF then immediately hold down BOTH the center and Menu buttons for a good 15-30 seconds or until it restarts with the Apple logo.
Resetting isn't always effective once and you may need to retry it several times to get it to work.

I just updated the software on my iPad and now I cannot update my Aps or install new ones. I ran a diagnostic and that resulted in "power issue." It wouldn't let me select what my options were. Any ideas?

Don't know where to get help. I just updated the software and I am having issues with not being able to update Aps or install new ones. The circles just spin and Aps just say "waiting." I tried running a diagnostic with the apple store and it came back with "power issues" (?) as a result. It wouldn't let me select an option to see what steps I could take to fix it, it just backed out of the page. I just don't know what to do.....

Hi,
Thank you for your reply, I did go to my general settings, but for some odd reason I don't have a restrictions setting, or a reset setting. I thought I could reset all the setting to see if it could be that, but as I said there aren't any.
My husband also has the iPad 2, and also did the software update and hasn't had any problems at all. I took both iPad's and compared the settings thinking maybe there could be a setting that could have been changed when the update was done.

I have a MacBook pro that has power issues and will not start but the hardrive is fine. I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one? Also, the software is not updated as the computer hasn't worked for about 2 months.
Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well? It is not saved in the cloud.
Thanks for your help, it is much appreciated.

You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
But it would be a mistake to simply put the old HD in the new computer.
These are the steps:
Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
Put it in a cheap enclosure
Connect it the new computer
Boot up new computer.
If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
Obviously chose the second option (another HD connected to this Mac) and follow prompts.
If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

Unable to Troubleshoot Power Issues on Mac mini 2011

I have been having odd and intermittent power issues with my Mac mini 2011 and could really use some help before I resign myself to taking it into an Apple Store. It's under warranty, but I now live in another country so I hope I don't need to ship it should it come down to that.
However, I have searched this topic a lot, and not only have I tried troubleshooting it, I haven't seen any power issues with other owners of this model. That leads me to think that the power supply itself is probably OK.
First of all, I live in China and the building I live in seems to have a questionable power supply. The air conditioner for example simply would not work and the repairman spent two hours messing around with wires inside the outlet and in the breakers. That did the trick, so I wonder if I'm simply not getting enough juice?
Main symptoms:
- My monitor recognizes an analog signal but will not light up (black monitor). Unplugging and replugging adaptor doesn't do anything.
- Startup Keyboard Commands (e.g. Cmmd-R) may work, but I can't tell because the monitor won't light up. Letting the computer boot up though I can hear keyboard volume keys and such making the standard sounds. I can usually restart using the keyboard too.
- My 2T external HD more often than not dismounts as well.
- I can't hear any computer activity after the chime (hard drive, etc.).
- Since I can hear the chime and there is audio feedback through the keyboard, I think that eliminates hardware problems such as logic board failure or bad RAM.
- I can't boot even if I unplug all USB peripherals.
- Holding down the power button (I have it set to make the computer sleep as well as shut down) often won't shut down the computer, but it seems to stay in sleep no matter how long I hold it. Unplugging the computer finally shuts it down, obviously.
- Unplugging and waiting 5 minutes or so and powering up again doesn't seem to make any difference, nor does switching sockets, plugging directly into the wall, etc.
Problems began about two weeks ago, got better, and then worse again. Now I'm just keeping the computer and monitor on (never sleep 24/7).
Miraculously, after much frustration and countless restarts, suddenly the screen will turn on to reveal a fully booted system that was running all along in the background. No startup screen- the monitor just magically comes on again. Often I find that my external has unmounted, but it's no big deal to get to remount. At this stage, the Mac is still very quiet and for a while the system is sluggish, though it hops back into action in 5 or 10 minutes.
At first I thought it was just my monitor, and though that's possible I suppose, it seems I'm just not getting enough juice. Once the monitor is on though, everything is fine: I can power it off and on with no problems. But I can't just leave my computer on forever though.
Any help appreciated.

Well, with the other monitor (which did not work with the mini either but worked fine on a laptop), I was able to narrow the trouble spot down to either a faulty Mini Display to VGA adaptor or a damaged port. I could determine that all the other ports (incld. the USB drive, programs, internet, etc., were all working fine behind the big black GUI all through sound feedback, so I seriously doubted it could be a supply problem or a residential electric problem.
I took my mini and adaptor to a "Mac Shop" (reseller) here in China, and found it quite professional, just like a Mac Store. They tested my machine, and although they didn't have VGA monitors, they said I could return the new $30 USD adaptor if it didn't work. But as I'm writing this on the monitor now, the new adaptor did the trick.
The long and short of all this is that I've read a lot about display problems with the mini and I suspect that most of these problems are adaptor related. I myself tried to save some bucks by buying a third party plug and lived and learned. I hope the Apple adaptor works like a champ, and if it doesn't, I'll know the first thing to eliiminate next time.

IMac (2007) intermittent power issues

Hi,
I have a 2007 iMac. I am getting intermittent power issues with it.
One day it wont power up at all...and might not power up for a number of weeks. And just when I have given up on it, it will power up and work for a wee while without any issues (including being shutdown nightly). It'll work for a while and then it'll stop working and again it may take a couple of weeks before it'll start working again.
Does anyone have any idea what might be the issue?
any help/advise greatly appreciated.

Hi IsMiseAodh - did you ever determine what the cause of intermittent no response to power was? I have a iMac with a similar problem. Thanks!

Hp pavilion dv6 power issue

I have a HP Pavilion dv6t 2300 laptop. Few days ago, the laptop suddenly stopped running with power issue. I bought a new battery thinking it was a battery issue. When I plug in the battery, AC led light won't turn on and the laptop won't charge. Soon as I take the battery out, AC led light is on.
I tried to turn on the laptop removing the battery with only AC power on, but it will not turn on either.
Is the the problem with the circuit board or is there any step I can do to make this work? Any help is much appreciated.

Have you tried another charger to make sure the adapter isn't the problem?

I recently moved my MacPro to a new building. Almost immediately it started taking a long time to boot. Twice it hung on the blue screen for approximately 10 minutes before continuing to the login screen. Problems were intermittent, sometimes it would boot fine. Then it started having trouble powering on at all. It would click and the light would turn on and off in less than 5 seconds. I took it to a different building: no powering on. I took it twice to the Apple store for the same problem, it turned on both times so I had to take it back with no help. Back at the original building, the computer turns on sometimes after leaving it unplugged overnight. I suspected an issue with the power in the building so I plugged it into a UPS. Initially it was only on a Surge Protector. On one recent occasion I accidentally nudged it with my knee and it powered down and back up. On another occasion I was sitting still watching a video and it powered down and back up with no intervention.
This will not reproduce at the Apple store. Each time it is there it has booted up perfectly using both my power cord and Apple’s power cord. Don’t know what to do next.
Any thoughts on what to try before replacing power supply and power cable? Is it possible this is not a power-related issue?

make sure to use something in 1000VA or better for your UPS and that it can support your system. May seem like $200 is a lot but then they work and give you adequate shutdown or to ride out a 5 minute power issue.

you don't need to nor is it that effective to leave unplugged over night or something.
hit the power on for 10 seconds while every cord and device is unplugged though.

Mac Pro power issue...

Wondered if anyone else had this issue. I have a Mac Pro from mid 2008. Recently, it has done the following:
- From a 'cold' start, it will power up for 3-4 secs and then power off again. It will not reach the grey screen.
- It will only fully power up after about 30-40 attempts...
Also, it will now sometimes just power off completely without warning.
Anyone else had these issues? It doesn't seem to be a graphics card issue.

Some more info on this problem, hopefully someone can help.
More system details:
Early 2008 Mac Pro
No extra memory or internal installations - just 2gb ram.
I found another thread which describes my problem completely....
"Problem 1: In the morning when I turn it on, on some occasions it will power on for 5 or so seconds, then power right back off again. Sometimes this happens after 5, 10 or even 20 seconds (right in the middle of OS X or Windows boot). The only thing I note is that if it can get as far as the boot selector (hold alt at boot) screen, it won't cut out at that point, only sometimes after I wait a moment then select a boot option. This can sometimes happen 10 or 20 times in a row before it will eventually turn on and function normally.
Problem 2: Random power cut off, sometimes at idle, sometimes while browsing, or using any other app. I can't pin it on any one particular function. I know it's not a temperature problem, I have temp monitors on my menu bar and as far as I can see it's been fairly stable in that regard. Most of the time, I can power up the computer again but very occasionally it will revert to what I described in problem 1.
I have run the apple hardware test, with no errors being produced, and have had the local apple reseller/service centre take a look, with their tech reporting no issues. (He referred to something called ARD being run on a cycle of 20 or 30 times with nothing indicating a problem) I've taken off every non essential piece of hardware, tried with only the stock ram - and the newer ram to no avail of my issues. The only thing that I can still suspect myself is a power issue, however there is another PC in the room that has not had any issues what-so-ever."
Needless to say I'll be soooooo disappointed if this 'top-end' machine has only got hardware to last 2.5 years. My pitifully power-less Dell has lasted longer.
Any advice please...?

Toshiba Sattelite C55 B5296 - Power issues

I purchased this laptop in December 2014. It has been nothing but problems trying to turn it on since day 1.
I troubleshot it early on and they shipped me a new battery. It did not resolve my issue
I run through the whole "remove battery, unplug, hold power button for 20 seconds, plug back in" thing. it worked in the begining but now it takes 10-15 minutes of trying that over and over to get it to turn on finally. I have to do this every single time.
It is still under warranty but i have to pay for phone tech support. What do you think the issue is? how can i get toshiba to fix this?

Hi,
First, I don't know what do you mean when you said "power issues"
Is it not holding any charge? or is it really not turning ON?
If the battery has been replaced already, then it requires servicing already. It needs to be sent to them.
It is still under warranty but i have to pay for phone tech support - if you suspect that your laptop has HW problem then you don't need to pay for the technical support as long as it is still under warranty. However that would really depend on what kind of power issue you are having.

Hello. I recently updated numbers on my macbook pro. I like the auto completion feature (proposing te word as I type). With this new update, I cannot see this feature and it doesn't work automatically. Can I have any help on this issue ?

This is really unfortunate. I'm sorry that nothing works. I was going to mention holding down the power button and doing a force shutdown but you already did that. You might need to take it into the Apple store. I don't know if booting into safe mode would help. You would have to turn off the machine again, hit the start button and hold down the shift key after you hear the tone, but normally you would let go of the shift key when you see the apple logo and spining wheel. Maybe by holding down the shift key after you here the tone will cause the screen to come back on? The other option is to start up from the 'install disk' if your machine came with one. You would insert the disk, then shut down the computer, and hold down the C key right after hitting the start button.

A well covered power issue post....

Hi!
Well, here goes again. I've read alot on the forum about power issues and the iBook...and now it's happened to me. I've posted to see if there's any 'fresh' advice.
Basically, my HD was totally screwed, so on Monday i had it replaced with a new 80g Western Digital jobbie. Brilliant little drive, so quiet and quick compared to the original Toshiba... Anyway, it was replaced by an authorised Apple retailer, got it home, re-installed everything, all was fine and dandy.
This evening, i came to use the computer. It powered up and everything. I'm on it now, so it's still functioning ok. The only problem now is the power supply.
My battery has been at 91% all evening, with the charger plugged in. The little light ring glowed orange when i first plugged the adaptor in...well, actually, when i teased it around the charger hole. When fully inserted, the battery icon detcts the power supply, but doesn't charge. I took the battery out and powered up the Mac with charger plugged in and it worked fine-but still no glowing ring.
Now, it was fine yesterday when i was doing all my install's, but tonight nothing. I've reset the PMU (or whatever it is), but thats not helped. I think the battery number is something like A1046...could that be at fault? Or is it possible that the engineers disturbed something when they had it apart? I've just spent £180 on the HD replacement, i can't afford any more, so if it's possible the engineers are at fault they can repair it!
Any advice or ideas gratefully welcomed-i love my Mac but the last week or so i've started to lose a little faith...
Dan

Hi Brody...
Thanks for the link to your page-very useful, with just the links alone.
I've made a little progress...well, not progress-i've managed to get light out of the ring on the charger barrel. When fully pushed in to the Mac, there is no light. HOWEVER, if i get the pin and touch it against the socket on the Mac (by socket, i mean where you plug the charger in) on the side, it glow's a faint orange. If i semi insert the pin/barrel slow enough i can get the ring to go Green, but it is microscopic movements to get this. This doesn't however, get the battery charging. As soon as the barrel is pushed home, it's just back to how it was-holding the battery's charge and thats it!
So, i've established that the charger ring still works, i've seen it orange and green. I've wiggled wires etc, changed plugs but it's still going out when fully inserted.
How bad does that sound?? Eeep!

Windows 10 Upgrade Salellite - Resolving battery and power issues

My upgrade seemed to go smoothly until I tried to unplug my laptop and use it with the battery. It shut down even though it shows that I have 100% charge. It was working fine before the upgrade. When I put my model into the site it says that it is not compatible for the upgrade but otherwise everything seems fine so far except that I cant use my battery. Someone I know suggested that I might need to download a driver but I have no idea which one or if that is the problem. I would appreciate some help with this. I have Satellite C875-S7303. Model # PSCBAU-009005. If anyone knows what I can do that would be so great. Thank you!

Serious Power Issues with T61

All,
The organization I work for has started to have some serious power issues with our T61 model Thinkpads. Additionally, the problem now seem to be carrying over into our T500 Thinkpads.
About 4 months ago we started receiving consistant calls regarding users that can't power their laptops on. These are T61 and T500 laptops mounted to mobile carts in our various nursing units in numerous hospitals. These laptops sit stationary for 95% of the time and are almost always plugged into wall power. We quickly discovered that the only way to get the laptops to power on was to unplug them from all power sources and reseat the battery, after which they powered right on. We've had this problem in the past with users T61s that aren't on carts, but this is slightly different as the batteries on the cart mounted laptops are always 100% drained after we reseat them.
I'm completely baffled by this issue. I've tried every variation of 3 different carts, -- one with external battery on cart, two without -- both 90 and 65 watt power supplies, and standard and 9 cell batteries that I can come up with and the problem continues to occur. Initially we had atributed the problem to ESD because this started during the low humidity months of winter, but it is now spring and the problem is still happening.
Under normal circumstances I'd just replace the few ailing laptops and call them in under warranty, but this seems to be a general model issue as this is occuring across the board on 100+ laptops at this hospital alone. Any assistance to help identify the issue and/or how to resolve it would be appreciated.
Thanks,
David

Slider5634,
Do you have a critical situation open for this? If so, while you are free to post here, working through the project office as a managed account should get you to the right level of support to address an issue that sounds pervasive, and may or may not be influenced by unknown environmental factors.
If you don't have a situation open, then I would urdge you to contact your account rep. If you need help, or unsure of this, please send me a PM with your contact information, and your hospital or corp account name so I can get you the right level of assistance.
jgm1234,
What model type T61's are you experiencing this issue with? Can you provide some more information here about the situation? Configuration, when this first started occuring, environment (connected to lan, wired / wireless, stand alone, all in same physical location, or distributed at multiple locations, etc)
Thanks!
