I accidentally inserted a wifi dongle instead of a flash drive into the sub port of my wireless Bluetooth boombox, the Sony ZS-RS70BTB, will this break it? The dongle was reading NOT SUPPORTED.


No, because the voltage of all USBs are 5 volts. It says unsupported because your Boombox doesn't recognise a wifi dongle. I guess it is looking for music files. The wifi dongle will be fine as it won't recognise a Boombox as it is looking for a computer or television.

My apple ipad is not reponding when iam charging it how do i reset it


Hello,

If you charge your iPad on a power adapter, the iPad should respond while charging, except if your iPad battery is so low the apps need more power to run.

If you charge your iPad on the USB port of your computer, it is normal you cannot use your apps as the iPad is not only in battery charging mode but also in synchronizing mode with iTunes in the computer. You should lose the habit to charge the iPad on the PC and use a dedicated power adapter instead, as dedicated power adapters charge the iPad battery 2 to 4 times faster than the USB port of most computers.
USB port power: 2.5 Watts in general (5 volt x 0.5 A = 2.5 Watts)
iPhone charger: 5 watts
iPad charger: 10 or 12 watts

Webcam installation


When you installed the camera did you use generic Windows drivers? If so, try going to the logitech website and downloading the latest drivers for the web-cam. Unplug the camera before installing the new drivers, it may prompt you to plug in your camera, if not plug it in once the installation is complete. Restart your computer and make sure your plugged in as well if it is a laptop. Another reason for no response could be no power is coming through the USB port, either because the power connection is burnt out (this doesn't mean that powered USB devices don't work in the port) or it reverted to a 1.1 version of USB. This is a common glitch that can usually be fixed by changing USB ports or restarting the computer. Make sure you don't have too many devices being powered only through the USB port. If any USB product also comes with an adapter always use that adapter if possible instead of using the USB to power it. This will ensure a longer life of your ports. If the latest drivers are installed and you know you have a working USB port that provides power then you more than likely have a bum camera. (Electronics generally fail either very early or very late in their life cycle)

My computer freezes when connecting WIFI adapter


Does this happen if you try connecting it into all USB ports? Try another USB port. Do you know if your USB ports are 2.0?

Computer wont turn on


"Then I came across the recommendation to check the USB ports for damage. Saw some of the pins bent inside the port. Once I fixed them, the computer powered back on as normal! Small fix for big problem. Cheers - Parveen"

My wife's Dell E510 also suffered from the orange blinking light on front, and would not power up this morning. I had just purchased a new power supply for another computer and swapped it with the Dell's. To no avail... Put the Dell back together and still no luck with a start. So I came across your site and remembered that recently the 6y'o had jammed a USB port in the front of the Dell and after bending that USB port back into shape every thing works again!

Who would have thought that a free fix would be so easy!

Thanks!!!
