Waking while closed and charging... every 15 seconds? iBook Sleep Apnea?

Ok, here's a weird one...
When my iBook is closed and charging, every 15 secs or so, it tries to wake up (you hear the drive engage and the apple logo lights up) for 1/2 second and then goes to sleep... and the repeats over and over again. If it's shutdown this doesn't happen but only if it's closed and "sleeping".
And speaking of sleeping... it doesn't seem to want to sleep either... If the power cord is not plugged in and I go away, it does not go into auto-sleep and eventually the battery dies. (The screen dims but that's it.)
I've tried the PMU reset (cntrl-command-option-shift-power) but I am not sure how to tell if that worked, other than the clock being reset.
Any other ideas? It's quite odd and can't be healthy for the machine.
iBook G4 Mac OS X (10.4.5)

Every time i try to charge my Ipod5. The charge icon pop on and on every half second, but no charging actually occur. I tried with all kind of charger.

Every time i try to charge my Ipod5, the charge icon pop on and on every half second, but no charging actually occur.
I tried with all kind of charger, everywhere in the house and the result is always the same.
So as you can see its a pretty big problem as now that my battery is dead, i can't use my ipod anymore.
The ipod is 2 months old.
Thank you!

I do not know what you mean by charger. Cable? Charging source?
Not Charge
- See:
iPod touch: Hardware troubleshooting
iPhone and iPod touch: Charging the battery
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.

Macbook pro Display freezes and darkens every few seconds

Hey ,
I just bought my Macbook pro 15 inch late 2013 few months ago , I'm new to Apple products ,
My screen started freezing and darkening every 4 seconds , starting from when I power it , until I shut it down even If I don'tt run any programs
I can't move the cursor while it's freezing or do anything , but for example If I write any text , the text will show up when it unfreezes , and If I'm listening to music the sound doesn't freeze . I tried the safe mode , and reseting the PRAM and NVRAM , running disk utility in single user mode and said that everything is fine , I checked my hardware using apple hardware test and also said that everything is fine , I removed the flash player thinking that it may be the problem but nothing changed . I don't know what I'm doing because as I said I'm new to all of this but I tried random things and nothing seems to work , I would really appreciate any help .
PS. when I tried taking a screenshot of the screen when it freezes and darkens a little , it appeared normal in the screenshot .

After the PRAM reset did you reboot the MBP and the projector?
If not, connect and power up the projector, the power up MBP.
The monitor itself could be on the way out, is there another monitor you can check it on.
Another thing you can try is a VGA cable with the DVI adapter and see if that performs better.
You can also try a different cable, since it worked fine in the past, I'm just trying to help you.

EA4500 Internet Port Cycles On and Off Every Few Second

I bought a EA4500 to replace my old WRT54G earlier this year. At first the router worked fine. After the automatic firmware upgrade to Cisco Connect Cloud, I was never able to get the Connect Cloud stuff to work, constant 500 Internal Server errors when trying to access the router with the Internet cable attached. So I downgraded back to the old firmware and all was well again. Then I started having problems a few months ago, when I would wake up in the morning, the router would be cycling the Internet port on and off. I could usually reboot everything and it would work the rest of the day. I lived with it like this a while, and support couldn't seem to find anything wrong. Eventually it started getting worse, until the point I could hardly ever get it to stay connected. I got Cisco to RA the old router and I figured problem solved. Now while the EA4500 was gone, I used my WRT54G again, and everything worked fine for nearly two weeks while I was waiting on the replacement EA4500.
So today the new EA4500 showed up, I connected and configured it, and it worked for a short time. Then suddenly I lost Internet, looked up at the modem and the LAN light was going on and off every few seconds. So I'm back in the same boat as before.
I've tried changing cables, same setup works fine with the WRT54G. Modem works fine with WRT54G and connected directly to the computer, zero problems. I tried lowering the MTU, turning on MAC address cloning, and various other things.
My modem is a HughesNet HN9000.
Any suggestions or ideas would be greatly apprecaited.
David

OK, the setup as is works fine with the WRT54G, just the EA4500 has the issue. It started working again last night, and was working this morning. It continued to work until about 3:15 PM today, and out of the blue, my computer came up and said the Ethernet connection went off, then it came back on, it did this several times...at the same time, I looked up at the modem, and the LAN light was going on and off on it also. So the router was cycling both the Internet and Port 1 on and off.
My HN9000 has a static public IP, and the IP it's DHCP server gives out is one digit different than it's own IP.
My router is set this way, and this is what it gets if I switch the Internet to Automatic (DHCP):
IPv4 Address: 97.xxx.xxx.194
Subnet Mask: 255.255.255.252
Default Gateway: 97.xxx.xxx.193
Then there are two DNS server addresses. I've tried the router setup as Static IP or Automatic (DHCP) and the problem occurs either way.
The HN9000 seems to pass all incoming traffic straight to the router.
One the LAN side, the router is configured to give out IP's in the 192.168.1.x range, and I have some static leases set. The router is 192.168.1.1.
Everything works with the computer connected directly to the modem, and with the WRT54G in place of the EA4500.
As far as calling Hughes, they won't support the router. If it works without the router, and with another router, they will say it's a problem with the router, which I think it is, just not sure what. Also, just to be clear, I do loose Internet access on my computer when the router acts up, but the HughesNet modem remains connected to the Internet.

Help MSI GE60 Fan keeps spinning to 100% and down every 10 seconds.

Hello,
I just bought an MSI GE60 and after 4 days of using, The fan keeps spinning up and down every 10 seconds even when nothing is running on the laptop. Have tried updating the BIOS and the drivers, but no change.
Every time i turn on my laptop this always happen. It goes on when my laptop is on. Even if im not doing anything it still keeps spinning up and down. I checked the temperature and its at 40+ C and my CPU usage is normal. Basically im not doing anything and it keeps doing this fan spin up and down.
Even when the cooler boost is on or off, its still does the same thing, the fan keeps spinning up to 100% and down.
Do you think this is a software issue or hardware? It is very annoying to hear the fan go 100% for 10 seconds then back to normal then back to 100% speed again and when i press cooler boost it doesnt do anything. So even tho the cooler boost button is off, it still keeps doing the 100% fan speed and back to normal again. It keeps repeating.
Can anyone help me solve this problem please? Thank you very much.

I have already tried uninstalling the S-bar and SCM drivers but still getting the fan noise. Also tried the no-battery and no-power reset for more than 24 hours but still having the same problems. The only thing that worked was changing the values in the RWeverything software. The only problem here is that it will work only until I shutdown the laptop. Once I do a cold boot I have to redo the RWeverything changes again.
@reprieve.nagrand
thanks for your case. Can I ask you a few questions more, please?
1. According to your model id your notebook came with just FreeDos, right? Could you please enter the Bios and go to System Information to confirm that you are using Bios 10F and EC version 14.04 (or 4.04)?
2. I urgently need a screenshot of your EC-Page within RWeverything after a cold boot without any modifications. Please try to make the screenshot at that time, when you can barely hear the fan anymore during the spin-on / spin-off cycle.
3. CoolerBoost: with a laptop that has been sitting idle for at least 20mins since last cold boot (no load, please!), can you turn on coolerboost by pushing the button somewhere to the left of the Powerbutton and let coolerboost run for at least 30 seconds. Then turn coolerboost off again and wait for the fan to slow down. Does the fan run continously after applying coolerboost or does it enter its off/on-cycle again. Please try it for at least 5 times and repeat it during other Windows sessions for two times. If this trick works, you are the man to make the video! Please help me out here. Please note, that the coolerboost trick will only work until there is load on the system again. If the fan speed picks up again due to load and slows down again, it will enter the annoying pattern, again.
4. While still reviewing the case and going through my notes, I came across an entry that I reflashed the EC-Controller with the same firmware one or two nights before the problem disappeared. This happened after uninstalling S-Bar and SCM earlier. So, if you are familiar with DOS-Flashing using USB-Sticks you could try to reflash the EC-Controller, than remove all power sources for at least 20 mins. If anyone else is experiencing the problem, please go ahead and report your findings. But please do the reflash only if you are familiar with such things and of course, please do so on your own risk!
Current status and work in progress:
As I haven't gotten hand on a video proofing that simply pushing the coolerboost fan button makes the problem temporarily go away, I am still stuck on there. The coolerboost solution works until the system load increases so much, that the fan level has to be raised. When the system load goes back to idle again, the fan level decreases and enters the off/on-cycle again.
The good news is I managed to customize a programm called fan control tools to somehow automatically apply the changes in RWeverything via a small GUI. This tool will also allow you to set fan profiles for Office, Games, etc. The bad news is, that this will trigger UserAccountControll at least once and it doesn't reapply after a cold boot or returning from hibernate, yet. I am now currently working on a solution that allows the new fan values to be set by Windows automatically using a batch file. This will apply the new values after a normal Windows boot, but not when returning from hibernate, though.
However, if you have found your remedy value for the fan issue within RWeverything, you can turn to Svet in the subforum "Notebook Modified & Private BIOS'ses & EC-FW". He will certainly be able to create you a custom EC-FW with those values written permanently in it.
My case:
The fan problem with my notebook has not (yet) returned. It has been running without S-Bar/SCM just fine. It can even process all fan profile alterations I have made. So, am I just lucky? While I do believe, that the fans of those notebooks experiencing the issue could be "somewhat odd", I find it hard to believe that my fan really suffered a mechanical problem. Without doing anything mechanical wise, my problem went away.
@Warner: I promised to present more videoproof of the case, but unfortunately I haven't managed to get a hold on a suitable video, especially since my unit has been running fine for the last weeks. Please be patient, if I have enough evidence I will post it asap.
One question bothers me though: looking at the EC-page of RWeverything, I was wondering if these are really all values, that the EC handles and checks. Are there any other values, variables that the EC manages and that are not displayed on the EC-page of RWeverything? The reason for asking this, is because I have a video showing the ECpage of RWeverything while the fan does his off/on-cycle and you can clearly see the RPMvalue correspond to the actions of the fan. As you pointed out, the boosts occur because the EC is missing a fan signal, I could clearly see the RPM value at offset 0xCD respond to the actions of the EC. If the controller looks for that value only, it should surely see the RPMs of the fan, as I can see them in RWeverything. So, I was wondering if the EC has other values not shown in RWeverything, that determine if the EC should enter the boost cycle?
While having another look at that video again, to me it appears as if the EC does this really on purpose. It tries to reduce the voltage of the fan to a point so low, that the fan simply starves. Then it boosts the fan up again. The only question is: why does the EC do that? Is there a leftover setting inside the EC - perhaps from another notebook - where such low RPMs were achievable?
You can find the video here in this zip-file: http://www.file-upload.net/download-7371226/MSI.rar.html
In the zip-file you will find three numbered videos, the first one is the most interesting as it shows the annoying fan cycle while the laptop is running idle. In the second one, the user put load on the system using prime95. The third one shows the system while it cools off again after prime95 has been stopped. Sadly, the video is too short as the system doesn't reach its lowest fan state again. The videos were taken in march in Germany, so the ambient temperature is around 20-21 °C or less (normal room temperature in Germany).

jku

My iPhone 5 continues to power off and on every 10 seconds

My iPhone 5 continues to power off and on every 10 seconds. It'll turn on, the apple icon appears, it then goes to my lock screen pretty quickly, then shuts off and does it all over again. How can I fix this? If I have backed up my phone to iCloud will I lose things like my notes and pictures?

Hey kenziephipps,
To make sure we are on the same page, you cannot keep your phone powered on as it turns off right after you see the slide to unlock screen after booting up. I would advise to try to restore your iPhone by following the steps in the article below. To answer your second questions, you should have it all backed up in iCloud like you said you did unless you made changes to what is backed up. With that if you did not make any changes you will have it backed up.
If you can't update or restore your iPhone, iPad, or iPod touch

My iphone switches off and reboots every 30 seconds

My iPhone switches off and reboots every 30 seconds, has antone experienced this problem? It happened a couple of weeks ago and I took the sim card out , cleaned it and put it back. This solved the problem for about 2 weeks, but it doesnt help now

Well Solution 1 : Reset your modem and Restore your Iphone 4 as a new iphone and try and it still keeps you off
try with another modem and it still keeps you off then your wireless adaptor might crash and you need to go to apple store

MacBook Pro won't boot - stays on black screen and beeps every few seconds

Hi,
My MacBook Pro has been having issues - when powered on wont boot past the white screen and more recently will just stay on black screen and beeps every 5 seconds. I had someone look at it and it seems apparently the motherboard is the problem
and either needs fixing or replacing. As I am traveling in Nicaragua the closest apple store is in Managua (capital). Would I be able to get the motherboard looked at and replaced if need be at this apple store? Also, does anyone know the approximate price for the motherboard to be replaced? Up until a few days ago the laptop was still turning on and working every now and then but now stays on black screen and beeps.
Any advice would be very helpful!
Thanks

Welcome to Apple Support Communities
It means that your Mac's memory is damaged > http://support.apple.com/kb/HT2538?viewlocale=en_US&locale=en_US
First, replace the memory modules. You can buy more memory at OWC or Crucial. It can also be replace by a reseller.
If it doesn't work, the RAM slots are damaged, so your logic board has to be replaced. It costs more than a half of the price of your MacBook

Finder crashes and restarts every 5 seconds or so!

I just installed the Quicktime Security Update. After I restarted the laptop and logged into my account, the finder began to crash and restart every five seconds, making the computer nearly unusable. I logged out and logged into another account that I have for debugging. In this account everything works. I have run "Repair Disk Positions," restarted, and tried again. Still I'm having the same problem.
Any ideas what the problem might be and how to fix it?

A hard drive if it has failed will sometimes allow you to boot into windows but may not work completely (Eg: In a scenario, where system partition ;where windows is installed works fine but logical partition of hard drive has gone bad).
On certain conditions, if the hard drive is on verge of failure may/may not respond completely. I would suggest you to run a diagnostics using Seagate Seatools which works on any hard drive irrespective of manufacturer to actually confirm if your hard drive has failed.
Also, any hard drive can fail in spite of it been 1yr old or 1day old as its all manufactured in bulk and most of it comes from China

Ibook cycles from sleep to wake (only when closed and charging)

I have been having an issue with my 12' iBook g4 for about 6 months or so. It will operate just fine on battery power, but when I plug it in it will start to act up. The screen will flicker as it charges for a few seconds, then it stops charging. Then it starts, stops, starts, stops. I have found that it happens when the battery is lower (under 20%) and if I turn the backlight down or off that it will charge for a few seconds longer each cycle.
In addition to this if I close the computer when it is charging it will not sleep, just cycle back and forth. The only fix I have found it to leave the lid open and put it to sleep from the apple menu. As long as it is open it charges fine.
I now have a new macbook, but I wanted to sell this one and would rather not have this problem. Any ideas?

Have you tried resetting the PMU?
Also for the problem with it not sleeping properly while closed, if you are still seeing this behavior after resetting the PMU, try removing the keyboard and replacing it again. Sometimes this happens if the keyboard is not properly seated.

Magsafe freaks, charging to not charging every few seconds

My computer has done this before but until recently wasn't bothersome. When my laptop is plugged in, the magsafe goes from green to orange and back rapidly. About every three to two seconds. The menu bar also changes with the light, going from charging to not-charging. Could this because the battery I have is real crappy? Its charge lasts for 15 minutes max, and charge time is the normal hour and half. Is there a work around for this? Anybody else have these issues?

given that your charger works perfectly fine without the battery it's 98% safe to say it's the battery .. I had dying batteries act almost the same on me before ..because the battery cells communication is not properly handled with the charger of the logic board, you get this happening .there is 2% chance it could be the logic board as well but given the condition of the battery and the behaviour without the battery I'd say is just very unlikely .. there is no chance this is a software issue
hope I could shine some light

Waking while closed and charging... every 15 seconds? iBook Sleep Apnea?
