Battery charges but ac power not recognized Presario CQ61

Hi everyone. I have a Compaq Presario CQ61. A couple days ago after doing the windows 7 system update (don't know if this is really related or not) my computer stopped recognizing the AC adapter. What I mean is the battery still charges all the way to 100%, but the OS never recognizes the computer as being on AC power, only battery. This is annoying and makes things like updates, installs, and gaming extremely difficult and/or impossible. I tried unistalling the Device in device manager and re-installing it. I can't reflash BIOS because the software requires I be on AC Power. I've even down a sytem restore and got nothing. Please help if you can...I really don't want to factory reset. My computer is not under warranty by the way.
Thanks in advance

My question regarding the icon was actually related to how it appeared in normal mode rather than safe mode. I apologize for not making that clearer. Safe mode was just a straight verification of the presence of the issue without doing anything else.
According to this document, which may not necessarily be updated, there are seven adapters that should work with this notebook.
HP 90W Smart Pin Dongle AC Adapter
HP 90W Smart AC Adapter
HP 90W Universal Power Adapter with USB
HP 90W Slim Adapter -
HP 90W Notebook PC Auto/Truck Adapter
HP 90W Smart Combo AC Adapter
HP Slim Travel AC Adapter
Most of these are 90W adapters. The only one that is supposedly rated at 65W is the last one and it's a special use adapter. I'm not certain why the replacements for this unit are marked as 90W and the one it originally came with is a 65W, but most HP notebooks do use 90W adapters and the symptoms do align with an adapter that is rated to too low for this system.
However, you could perform a system restore followed by a full system recovery (if the restore didn't work) to rule out any software (e.g. drivers) issues. By chance, do you happen to have access to a 90W adapter to test with?

My iPod is charging but it is not recognized by my computer.

I am a new iPod user and I am trying to put music on my iPod. When I connect it to to my computer the charging icon appears but neither my computer or iTunes recognizes it. When I go to Edit and Preferences in iTunes it says no iPod connected but I know it is because it is charging. Can anybody tell me what the problem is and how I can fix it?
Windows XP Pro

I also have this problem, although I don't seem to get the charging icon either. I recieved my IPOD at xmas, connected it to my machine and now I can no longer see any USB storage devices. Connected my IPOD to my laptop and everything is ok. So it is not the cable or the IPOD. Previous to connecting the IPOD to my machine ALL usb storage devices worked perfectly. Somehow my USB has been corrupted. (See my previous post "USB no longer recognised for IPOD or ext drive")

Battery said it's charging but laptop is not holding any charge. At 0%

Having a battery issue and laptop not holding charge. My laptop was working fine yesterday and this is the first time I am having this problem. When I plug in the charger the light turns orange as to indicate it's charging but this is not the case. Also the orange light flickers to white sometimes to note full charge but I'm at 0%. I can only run the laptop for a minute or two before it dies. I checked the icon on the bottom right and it shows that it is plugged in and charging but stays at 0% and dies in a few minutes.
I've tried searching and tried everything.I can't remove battery easily as it is an ultrabook. I tried waiting for laptop to cool, shutting down manually, disconnect charger and plug back in, trying different wall socket. Can't seem to find a solution please help!

Hi nomanhp,
First Try these Steps -
1) Go to Device manager (Control Panel) and check with battery (ACPI and Adapter) that weather its installed or uninstalled.. If uninstalled then reinstall it.. If you find the battery installed in the control panel, try uninstalling it and reinstall.. See if u find any change..
2) If no Change found. Along with Following the above steps, shut down and restart your laptop for every uninstall..
I mean, at device manager, uninstall the battery, turn off the laptop and start the laptop again (you might also select "restart with last good configuration" by pressing F8 while restart)... While reinstalling, the battery gets automatically reinstalled..
You might also try clicking "scan for hardware changes" at device manager..
3) If the problem Still persists, then ur battery is probably dead and is malfunctioning.. U would need a new Hp Battery..
If none of these above resolve ur problem, then there should be a problem with ur power board and u would need the help of expert to fix it.
Mark this Reply as "Accept as Solution" if it solves your problem. Click "thumb up" just to say Thanks..
Good Luck!!

Howdy AndieKanaras,
It sounds like your iPhone is being recognized everywhere but in iTunes. I would use the troubleshooting for that issue in the following article, named:

I have my ipad plugged into my mac to charge, but it's not showing up in itunes. Can i just unplug it without hurting it??

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.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

Do other USB devices work on your MBP?
Does this USB stick work on other MBPs?
There is a possibility that the stick requires more power than the MBP delivers. Try it on a powered hub.
Ciao.

Fluids and electronics do not mix.
You have caused some serious damage to parts of your computer, and likely voided the warranty until Apple completes a repair and re-certifies it.
Step one is to turn it off and do NOT (did I say do NOT yet?) turn it on again yourself.
Take it to an Apple store and be prepared for a large repair bill.
Sorry, but that is the truth.

Trying to move my iTunes Music and other media from the main drive on my pc to an external hard drive but iTunes is not recognizing the new file location? Ideas?

Trying to move my iTunes Music and other media from the main drive on my pc to an external hard drive but iTunes is not recognizing the new file location? Ideas?

Hello there, Underwriter.
The following Knowledge Base article provides in-depth instructions on how to migrate your content to an external drive:
iTunes: How to move your music to a new computer
http://support.apple.com/kb/ht4527
Particularly of note for your situation:
External drive
This option requires more work than Home Sharing, but it creates a backup of your iTunes library on the external drive in addition to moving your content.
Notes before you start:
You can use most iPods as an external drive.
Windows operating systems don't recognize Mac OS-formatted disks (HFS or HFS Plus formats). Because of this, you can't use a Mac-formatted iPod or external drive to move your music to a Windows PC. See iPod: How to determine iPod's hard disk format if you're not sure how your iPod is formatted.
Mac OS X can read Windows-formatted iPods and drives. This means there are many ways to migrate your information from your old Windows-based PC to your new Mac.
Mac OS X: To be sure external drives appear on your desktop, choose Preferences from the Finder menu. Be sure the options for "External disks" and "Hard disks" are enabled.
Part 1: Locating and consolidating the iTunes Media folder
Part 2: Copy iTunes folder from the old computer:
Part 3: Get iTunes ready on your new computer
Part 4: Back up any music that's already on your new computer
Part 5: Copy music to your new computer
Part 6: Add preexisting music that was on the new computer back into the library
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

i have installed updated version of itunes but it is not recognizing my devices can anyone help

Many thanks.
That suggests that another application has stashed old QuickTime componentry in your system files.
So just in case we'll go looking for older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view settings.
In your Start menu, open Computer.
In your Organise menu, select Folder Options.
In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
Click OK.
Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
Open the "Windows" folder.
If you have a 32-bit version of Windows, open the "System32" folder.
If you have a 64-bit version of Windows, open the "SysWOW64" folder.
What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)
