Depends on the laptop model but normally but it could be one of three lights. First, the disc utility light (tells you when your hard drive is in use, either reading or writing data). This light normally looks like a square, 2 or 3 circles stacked on each other or a small cylinder. The next type of light is could be is your wifi light. This light tell you whether the computer wifi is one or off or if it is transmitting data. Normally this like looks like an antenna with semi circles coming off the top of it like radio waves. Lastly, it could be your battery light showing you whether the laptop is charging, or charged. Normally this light is shaped like a battery and may have a little lightning bolt in the middle of it. Without know exactly what the light looks like, it is hard to say but these are the three most common lights.
Good Luck and vote for me if this answer helped you out. Cheers.

Wii board


Make sure that you have synced the board to the wii (similar to a controller). You have to take the battery cover off the board and push the sync button. The blue light will start flashing. From there you need to open the front cover of your wii under the power button.

From there you start up wii fit and it will prompt you to turn on your board. You should get a solid blue light. If you don't, you may need to try syncing again.

I have Logitech wireless headphones for my Ipod, and I can't get them to work. When I press the on button on both pieces, it goes solid red and not blue.


Visit the Logitech support website and find the instructions to reset and pair them. Since yours is for an Ipod I'm assuming you have the older white/grey model and not the freepulse headphones. The procedure is not the same. From memory the procedure it to reset both (look for the small hole to insert a paperclip). Once both are reset begin with the transmitter. Hold the power button down for about 30 seconds until the light flashes red and blue. When it does do the same for the button of the headphone until it flashes red and blue. When both are flashing red and blue they should pair together and the lights should turn solid blue..
