If you are using < 2.0 usb port, I found this on another website... "it cannot derive much power from a PC USB socket, it powers down after about 5 minutes in order to charge the battery quicker. The mains charger can be more powerful.
The green light just means that external power is applied, nothing else.

As for the constant re-booting, that definitely isn't right. Suggest you try a reset (with a pin) and/or a "return to factory settings" (in the menus) - You will lose ALL your settings and saved places if you do that one.
If it still does it on another route, send it straight back to the shop."
Else you may try ensuring it is compatible to your os.

Hi, I have a Dell Inspiron 531 built-in webcam that don't work. Can you tell me what i need to do to fix this?


Step 1: First connect the bluetooth device to USB port on your computer and check that it is detecting on your computer or not.

Step 2: Now insert the bluetooth software driver CD to your system that will auto start after few seconds then follow instruction to finish bluetooth software installation.

Step 3: Now go to 'start -> Devices and Printers' and click 'Add a device' from top of the window.

Step 4: Now your Windows 7 system will search the bluetooth device which connected to your system.

Step 5: Click the bluetooth device you want to install from the list and then click the 'Next' button and wait for windows to configure the bluetooth device. If prompted to enter a passcode, enter the default code listed in the bluetooth device manual. In many cases, the default passcode will be '0000'.

Now the bluetooth device has successfully installed and ready to use.

Note: If you bluetooth device was not listed in the search results from Step 4, make the device discoverable. Access your Bluetooth-enabled device's settings page, and turn on the device's 'Listen' or 'Discoverable' function to allow you computer to find it.

NIC internet connection problem


I would start by looking in device manager for any devices with a bang on them (a bang is a question mark or exclamation point). It's possible that your wireless adapter does not have drivers loaded for it. Usually, before a reinstall you want to back up all your drivers, because this will happen. I can recommend a program called Driver Magician Lite available for download here:
http://download.cnet.com/Driver-Magician-Lite/3000-2242_4-10521270.html?tag=mncol

But since you don't have this luxury, you now want to look for devices in your system that have driver problems, specifically your network adapter(s). Can you connect with an ethernet cable?

Assuming you find the wireless adapter (or unknown device) in Device Manager, you can try these things:
1. try installing a device driver; connect to the internet using a cable for now
2. update the current driver; connect to the internet using a cable
3. remove the device and let Windows "find it" again and reinstall the driver to fix a corrupted driver file

My computer cannot detect usb my computer model is 6bxa-61 samsung


You were saying that your computer could not detect any USB devices? Or just one USB device? Alright, you need to isolate the problem, follow the steps below:

1. Use at least 3 USB devices and connect them one at a time to the USB ports of your computer. If the first USB device is not detected, mark the USB port on your computer with "X" mark.

2. Now, connect the same USB device to another USB port of the computer. If you get the same problem, use the second USB device and connect it to the computer. If all 3 USB devices are getting the same problem connecting in all the USB ports of the computer (either on the front or on the back of the computer), then you need to update or re-install the USB driver to your computer.

3. Contact the manufacturer if the computer or the board and see if they could provide a USB driver for *********** board. Tell them what operating system (OS) you are currently running.

Have a great day!

I have no sound and a split drive


It seems to me that the driver is not installed in your Japanese XP version. You should get the model number of the sound card if possible and go to the manufacturers website. Do a search for the driver, download it, and install it. This will fix your problem. To check you can right click on my computer, click properties, click system, click device manager, and you should find a questionmark in the list. If this is found, it confirms that you need to download the driver. Good Luck!
