(See <a href="PowerSupplies.htm" target="" title="Open "Power Supplies" in popup window" alt="Open "Power Supplies" in popup window" class="MCXref_0">Power Supplies</a> for options). If your board has a power switch, make sure it is switched on and the power indicator is lit. If you are using a 9V battery, try a fresh one. If you are using a battery pack, make sure the batteries are all inserted into the pack correctly; try fresh batteries. If you are using a wall-mount supply, make sure the wall outlet is not turned off at a wall switch. If you have a voltmeter, use it to measure the voltage supplied by the battery pack or wall-mount to rule out defective power supply hardware.</span></span>

On some computers, the internal USB hub will freeze when disconnecting a USB 2.0 device from a USB 3.0 port. This may cause all USB ports on the computer to become unresponsive, requiring a reboot of the computer to remedy the situation. System updates from your computer manufacturer may correct the problem.USB 3.0 ports can sometimes be identified by a blue tab inside the socket.<br /><img src="../Resources/Images/USB_3_258x115.jpg" title="USB 3.0 ports have a blue tab inside." alt="USB 3.0 ports have a blue tab inside." style="padding-top: 5px;width: 258;height: 115;" /></span></span>
