I don't know what else to do

Since I got my alienware 18, I have never been able to sync any type of I-device , be it a ipad or iphone , ipod , ect. I posted about it awhile back, but I can't seem to find anyone who knows how to fix it. Basically the iphone (or any other iphone/device) will connect, you will hear the windows beep , then it will immediately disconnect, then connect again, and do this over and over until i unplug it from the usb port.

This is what i have tried. I have tried doing it with a fresh install of windows both 7 and 10. I have unplugged any other devices plugged into the usb ports. I have tried different USB ports, I have tried disabling the computers ability to disable a usb port to conserve power. I have tried enabling USB debugging to disable usb 3.0 ( i was told this is how to do it, but it didn't work either) I have installed the newest version of Itunes.

Now today for the first time, my external hard drive is connecting and disconnecting. However it has been only doing it like once every 20 minutes or so. The i-devices is like rapid fire .I also turned off charging from the one usb port on my alienware laptop. I tried disabling my overclock to see if that worked. Nothing.

Could it be that the laptop doesn't have any USB 3.0 ports? I've tried deleting all the usb drivers and reinstalling them with alienwares drivers and that didn't work either.

the only device that hasn't disconnected has been my mouse. I have also tried unplugging the laptop, removing the battery and draining it of any power which didn't work either.

Please if anyone has any ideas at all, i will try it. If someone has an alienware 18 and they are able to hook up a iphone ect with no problems at all, can you send me the drivers your using, possibly even a snapshot of your device manager with your USB section opened up.

Thank you for anyone who can help. Im thinking maybe i need a new motherboard or something. I have no warranty left though.

 

Perhaps your motherboard is one of the earlier models and has a HM87 chipset with C1 stepping, in which case you're susceptible to the effects of the S3 Sleep bug. HWiNFO can tell you the particular stepping of the PCH:

If it is a C1 then try disabling the S3 (and S1+S2) sleep state:

Thank you for your reply. I do have the HM87 chipset. I disabled what you showed me as well as other power saving feautres. Rebooted, checked to make sure it was disabled (it was before i disabled S3) and it still doesn't work. im gonna post a link of a video of my computer showing what happens.

here is the link to a video of what is going on .

 

Did you check whether the HM87 is C1 or C2?

If not, it could be a power issue due to a faulty capacitor or mosfet on the mb. Some other device might also be interfering with proper operation of the USB hub. An internal component, such as a touchpad or wifi/bt card, can also be wired to the same hub as the external usb ports:

Spoiler: USB devices, power

If there's anything else hooked up, then unplug/disconnect these devices and try again. To rule out driver issues or other software interfering (such as virus scanners and hardware monitoring tools); use safe-mode or, better, a (live) linux install. Also, since windows beeps; check the Event Viewer, perhaps it'll yield a useful description for the error encountered.
