USB Ports work Intermittantly on Pavilion Notebook

I have a HP Pavilion dv7-2270us Entertainment Notebook PC that is running Windows 7. The USB ports seem to work intermittantly. There are two regular USB ports on the left hand side and one on the right. I have an iPhone, Adidas miCoach, and wireless mouse that I usually have plugged in, and lately nothing is recognized.
Sometimes I get an error that the USB device is not recognized, sometimes I get nothing at all as though the ports aren't even there.
I have tried taking out the battery, replacing and rebooting. I have also tried uninstalling the USB Root Hub, and then the Root Hub plus controllers. When I did this it seemed like it worked - I plugged my mouse in and it worked! I plugged my iPhone in and now nothing works again.
I have Norton 360 Installed (in case that is an issue), and I also have some old Sony Ericksson software that I've recently uninstalled because someone told me that it wreaked havoc on their machine in terms of their device drivers.
The laptop is just out of warranty (Dec 2010) so this is a relatively new machine. But I love all my gadgets and need to be able to use them all!

I have a new Macbook pro, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop.

I have a new Macbookbook, about 2 months old, and at times running video, the fans starts and does not stop. how do you get it to stop. Also i am thinking once the video is done the fan should be slowing down and getting quiet on its own.

Your fan(s) will run at high speed (i.e., loudly) while video is playing, and you can't get around that.
If your fans are not slowing down within 2-4 minutes after CPU- and/or GPU-intensive usage ends, and the application that was showing the video is still running, Quit that application. (In fact, if you're accustomed to Windows, you may not realize that simply closing a Mac application's window does not quit the application. You still need to use the Quit command in the application-name menu. There will always be a bright dot beside or below the application icon in your Dock for each application that is open.) Quit the ones you aren't using, and see whether that allows the fans to slow down without restarting the machine. If that doesn't do the trick, reset the SMC:

HT1766 My mini Ipad is only 2 months old and it has frozen. The screen says that the ipad needs to be backed up on icloud but the touch screen has frozen and I can even shut it down. Suggestions

Does anyone know how to unfreeze a screen.

Try to reboot it. Hold down the sleep and home keys until you see the silver apple, about 20 seconds or so. It should reboot and work for you.

TS1538 My 4 month old iPhone 5s stopped charging, original cable with adapter works fine on other iphones

My 4 month old iPhone 5s stopped charging, original cable with adapter works fine on other iphones.
I have tried restarting iPhone while its connected to my macbook pro and when it restarts, I see it starts charging again.
After this, when I plug phone to wall outlet, it works perfectly and charges but next day again it stops charging.

Will Apple cover this under warranty if the port is damaged due to unknown reasons as its under 1 yr warranty?
Also, I am out of USA now and would like to know if I can send it through a friend and get it checked out by Apple tech...
Never has any iPhones of all generations that I owned gave such problem.

HT202157 So why doesn't the new software upgrade the Apple TV to 1080hp...from the 720hp? Do I have to buy a new Apple TV to get that Upgrade? Mine is only about 2 months old! Very frustrating if thats the case!

If you want 1080, you will need to purchase the new Apple TV.

How do I sync my iPhone 5 to my new PC? iTunes will not recognize it even when plugged in the USB port. Settings General iTunes wifi sync is still my old laptop. Any help is appreciated.

Have 2 month old Touch 4th Gen why is the battery life so bad?

Hi everyone,
I have a 2 month old 4th gen Touch and find that the battery life is very bad. My 2nd gen Touch still works and I've had that since it was released (and I understand why the battery isn't so good on that anymore). Ever since I've had this I have to charge it at least once a day, thought I had heard that the battery life on the 4th gen was never good to begin with but this does seem very frustrating. I admit that I tend to use my Touchto play games and use the Internet. I always turn off Wi-FI when not on the Internet and I turn off push notifications and watch out for the brightness as well. I have IOS 5.1 but was wondering what other people think about the battery. I know I'm still under warranty but do not want to just get another touch if this will happen to any touch I would get as a replacement. Any answers would be greatly appreciated.

How bad is "so bad?" You need to determine the total amount of operating time from full charge to auto-shutdown (ignore any low level alerts that may appear).
I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know whether or not a battery problem exists.

If the rubber coating on my 10 month old charger tears, exposing and disconnecting the metal wires rendering it unusable, should I be reimbursed or given a new charger? (all proper storage measures were taken).

My 10 month old charger's rubber wires have torn between the magnetic piece that is put into the computer and the box piece of the charger. As the metal wires inside are no longer touching, the circuit cannot be completed so charging cannot occur. For the past week I have had to hold the wires together manually, with my hands. No amount of tape has been able to keep the tear from further increasing and I now fear, for safety reasons, that holding metal wires containing an electrical current with my hands is not an excellent idea. I used the flaps on the box piece and when storing it, have placed it in a compartment with lots of space to avoid torsion. Regardless of my precautionary measures, the tearing still occurred. Am I simply out of luck and should just shell out the however much money to buy a new charger or am I entitled to receive a new or functional one from apple? I should probably finish this up since I currently have 10% battery life and no way to charge it. I will attach pictures if possible.
Thank You,

if your mac is still within it's limited hardware warranty or applecare protection plan, you can get a replacement adapter by going to apple store or service provider and exchanging it
or can call applecare and they will send out a replacement (they put a hold on the credit card for the amount of the charger until they get the damaged one back)
if it's no longer covered under either of these things you can still use the same options to replace it but would be out of pocket expense.

Hp Pavilion DV4-1235ee No sound & Usb port not detecting.

In my laptop Hp Pavilion dv4-1235ee there is no sound coming from the internal speakers. If I connect external speaker its works fine. Usb port is not detecting now. any help will be appreciated.

What is the current Operating system on your notebook? I suspect we have issue with internal speaker on hand...but would like to reinstall the Audio Driver and check...
Again for the USB, we can try and install Chipset driver and check...

HP Pavilion dv6-6b10tx two of the usb ports are not working

I have recently bought a HP Pavilion dv6-6b10tx....and had it fixed by hp for a problem with the beeping noise.
After sending my laptop for repairs( replacing the system board), I received my laptop but two of my usb ports are not functioning...
I did a bios update and did the hp update to see if it actually fix anything but not luck. So I went device manager and found a exclamation mark on the renesas electronics usb 3.0 host controller with a device status 'This device cannot start. (Code 10)'. What do i do??

The question is why is the port not working? Is something in the port that you can see? If not, then there isn't much you can do but take the computer in to the genius bar and have the techs see if it is a circuit problem that can be fixed.

Usb unrecognisable message now appears when i plug my old ipod into the usb port on my v70. It used to work so i assume this is a problem caused by updating to the latest software. Has anyone been successful in downgrading to an earlier os using itunes

I now get an urecognisable usb device message when i plug my ipod classic (ipod colour?) into the usb input in my Volvo V70. The ipod used to work, but since updating the IOs it doesn't. Can anyone tell me where i can find a copy of an old ipsw which does work so that i can downgrade back and acheive compatibility again,
thanks chris jones

perhaps someone from apple tech might contribute as the software upgrade has rendered the device useless for my purposes
