Computer power issues

Everytime I plug in my Ipod nano my computer resets what is wrong with it?

Hi,
Had the same problem as yourself with an iPod Nano and Windows 2000 Pro... ...turned out to be a conflict with my CD burning software - EZ CD Creator Platinum 5. I updated to the latest iTunes and iPod software, uninstalled the burning software and all was good. Don't know how to get them to co-exist though. I've also read that some virus checkers can give a similar problem, and disabling scanning of the iPod's drive letter can resolve. Hope this helps!

Computer power issues ! turns on then off turns on then off ! Help Please !

When I attempt to turn on my computer the power light comes on and I hear the fans running but after a second or 2 the light goes off and the fans stop running, after a count of 2 the light comes on the fans start up again and the same thing happens again, on off on off I don’t have to touch the button the only way I get it to stop is pull the plug from the wall. I thought maybe it was a power supply issue so I replaced this with a new one but I got the same results. Does anyone have an ideas????

Dear Customer,
Welcome to the HP Consumer Support forum.
In order to isolate the issue, please try and perform few basic steps as follows:
1. Open the hood and ensure the 4 or 6-wire power supply cable is seated into the connector on the system board
2. Check if a device is causing the problem by removing ALL attached devices (such as hard, diskette, or optical drives, and expansion cards).
3. Power on the system.
4. If the system enters the POST, then power off and replace one device at a time and repeat this procedure until failure occurs.
5. Replace the device that is causing the failure.
6. Continue adding devices one at a time to ensure all devices are functioning properly.
7. Locate the header and jumper labeled CLR_CMOS
8. Remove the jumper from pins 2 and 3.
9. Place the jumper on pins 1 or 2.
10. Put the jumper back on pins 2 or 3
11. Replace the access panel
12. Reconnect all the disconnected devices one by one and then power on the unit and check if the issue persists.
In case issue persists please get back to us and we would be glad to assist you.
Hope this helps, for any further queries reply to the post and feel free to join us again.

Lenovo Ideapad flex 15d computer power issues

My Ideapad Flex recently developed two issues.
Problem 1: When the computer goes to sleep (via start menu, closing the lid, or being inactive) the hardware turns off completely. In Windows 8.1's event viewer there are two errors that state that power failed unexpectedly.
This has occured with the power adapter connected, and without. It also occured for Ubuntu 14.04.
Problem 2: The computer (when powered down) only occasionally responds to the power button, and fails to boot when it does. I have found a temporary workaround - resetting the BIOS - however that only works one time per reset.

I just purchased a flex 15D a noticed that upon start up, there's lighting behind the keyboard, and (being new to PC laptops) it took me two nights to figure out that the only way to turn it on is Fn+space.

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.

USB Power Issue

Suddenly my MacBook Pro won't charge my iPhone. It says there isn't enough power:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
I get that message even when there is NOTHING connected to the USB cable when I plug it in.
It is allowing me to continue to use a Kensington Expert Mouse corded trackball.

For power issues anywhere, perform an SMC Reset.

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.

Power issues with Mac Pro (early 2009)

I have a problem that seems to be related to power issues. I have to disconnect the power cord for a few hours, then, I connec it again and turn on the mac. I have replaced the power supply (by a certified technician) and the problem seemed solved. Nonetheless I added a fourth disc drive and the problem presented again. I have two video cards a 20" cinema display and a 24" LED display (Apple) connected to a GT120. 10 GB RAM.
Every time I connect the computer there is an Inrush alarm in the UPS I have it connected to.
Does anybody else have had with this issue?

As Allan mentioned, the UPS is way too small for the task. I've seen mention of folks who have 1300's that are fine, but target recommendation (and what I plan to get soon) is 1500. Also, make sure you don't have a laser printer plugged into the same UPS.

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...?

I believe it's a power issue

After reading these forums since the day the iPad came out, I have narrowed it down to 2 things. A hardware issue with the wifi antennas. Or, a power issue in the software of the OS. Simply put, the wifi isn't getting sufficient power to find a signal, maintain a signal, and use a signal for data transfer
The fact that people are fixing their problems (at least the reconnect after sleep) by turning up their brightness is a huge insight into this issue.
The main issue that plagues us all seems to be Wifi dropping/slow/reconnecting etc. I would like everybody with this problem to do a test for me, as this method I have found is the ONLY way I have gotten my iPad to behave.
1)Turn your brightness to maximum
2)Plug in your iPad and try the wireless (to a wall charger, NOT your computer). Make sure external power is going to your iPad.
Try the wireless now and report back, I have a feeling the power management part of the software is failing somewhere..
Thank you all

The power saving code that was written for the wifi radio is such that the radio is being shut down, put to sleep or otherwise uninstalled due to some sort of glitch. When you receive the message to re enter the security key, that itself suggests the connection is being reset, and when it doesn't work, that's because the system has already disconnected (or somehow deactivated) the internal radio. This is why a power off and restart fixes it every time.
That said, if you follow the instructions in my other post you can avoid a complete shut down and restart.
When you see the message to re enter the security key, ignore that (DO NOT input the security key) and immediately press and hold the power button until you see the "slide to turn off" screen. Then simply touch the "cancel" button at the bottom of the screen and the device reinitializes the wifi radio. This has worked for everyone that has this problem, (hence a lost connection).

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!

IBook G4 + Power issues = No support from Applecare?

This post is going to be kind of a rant plus an actual question:
I've noticed on-going power issues with my iBook G4 for a while, and have called Apple about it. Despite having an AppleCare plan on my iBook, they said there was nothing I could do besides buy a new battery and see how that goes. I said that being a hardware technician, I didn't think the issue was with the battery, but we'd see how it goes.
Last night, my iBook powered itself off for no reason. Worked fine when I had it on the AC adapter, but powered off as soon as I unplugged the power cable. The battery indicator on the battery did show three bars of power.
I called Apple this morning, and they said to check the battery at the closest Apple Store to me. I told her that the closest one is two hours away. She gave me the number to a local service center, who upon calling, has been closing for 5 years.
I called Apple back and spoke with another technician. Told him that I was sure that the problem was with the system itself, as other people have been having this issue according to the forum. The response I got was a little...well, not good.
Even though I have an AppleCare Protection Plan on my iBook, even if the problem is not with the battery, and with the system itself, I was told I would need to pay for all repairs. I was like "Isn't the point of an extended warranty is that I wouldn't need to pay?" The tech explained to me that "AppleCare isn't an extended warranty, it just guarantees support through them if you call in." Needless to say, I got off the phone with him after that sentence and thanked him for his time.
Long story short: I'm stuck. From experience, do other people on here think its the battery or the board? Apple seems to be of no help at all, despite having a three-year "protection plan" on the device.
What does anyone else think?

Do you by any chance have a friend with a battery that is known to be good? If you could determine that your computer has the same problems even with a battery that is known to be good, then you have a good argument for the problem being with the board. If the problems disappear, then they might be due to a failing battery.
If you aren't satisfied with whoever you talk to at tech support, you can request to talk to a product specialist--these guys have a higher level of knowledge and experience and you might get further with them than you can with the first level support person.
I agree that problems with the board should be covered by your warranty. If you are at all close to the end of your warranty, be sure and get a case number. If you can establish that the problem initially occurred while you were under warranty, Apple should honor it even if it takes a little time to resolve.
Good luck!

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.

Z77A-GD65 power issue/bad system board?

Looking for advice. I am afraid its a bad board, but some symptoms point at power which also makes no sense.
This is what the WHOLE system should look like.
MSI Z77A-GD65 system board
Intel 3770K 3.5Ghz
Anted Kuhler H20 620
G.Skills RipJaws 16GB 1600Mhz DDR3 F3-14900CL9Q-16GBXL (on the test list)
Asus nVidia GTX 680 video card
OCX Vertex 3 256MB SSD
Seagate 500GB data drive
Razer Lycosa Keyboard
Razer DeathAdder Mouse
Antec Sonata IV case with Neo ECO 620W power supply
It seems to me that 620W should be more than enough. According to my calculations thats roughly 330W of power draw against a 620W powersupply.
I am not currently over clocking.
So what the system does look like is:
If I connect the 500GB drive then windows starts rebooting as soon as the Windows logo comes up.
If I place all four sticks of RAM in the system windows starts rebooting as soon as the Windows logo comes up.
If I leave the 500GB standard sata drive off and only use 3 sticks of RAM... well we get a solid system and I am writing this message on it.
3 sticks of ram appear to work in any 3 slots and allow the system to boot, except 1,3,4. That combo also resulted in the reboots at the windows logo.
I first thought it was RAM, originally I was using Corsair Vengeance. I saw some posts here about people having the same problem, and noted that the Corsiar RAM was not tested and switch to a the tested G.Skill instead.
Any ideas? It does not completely seem like a System board issue, but it certainly should not be power. All heat levels are well within normal and as I said the system works great if I leave off the drive and one stick of RAM.
Thanks guys....

System torn down, and put back together. (Found out I was out of Thrermal Compound, so I had to run to the store to get some.)
No long leads, only 9 stand offs matching each mount point on the systemboard.
Back together... problem is the exact same.
However, back to the hard drive issue. I decided to play with that since I was getting no where with 4 sticks of RAM.
What I have discovered is that with NO sata cable connecting the drive to the system board, if I try to power the two 250GB standard sata drives the system reboots just as the Windows logo should come up.
The fact that this behavior is so close to the RAM behavior... I am back to thinking its a power issue, though system board is still a chance... its just easier to buy a new better power supply than the Antec Neo Power 620 that came with the case. (I have not ever had a problem with Antec before, and will likely just buy one of their higher end power supplies to replace it, but I think I will try it next, just in case.)
I am not seeing any strange behavior power wise as far as any monitor shows... but connecting power to a sata drive that is NOT connected with a sata cable and causing a reboot just screams power at me.
Anymore thoughts today. In the mean time off to play Secret World with just the SSD and two sticks of RAM, which still runs rock solid.
