</p><h3><a name='toc7' id='toc7'></a>What if my board doesn't turn on (the green power LED doesn't light up)?</h3>
<p>If you're using a USB board, make sure that the jumper (little plastic piece near the USB plug) is on the correct pins. If you're powering the board with an external power supply (plugged into the power plug), the jumper should be on the two pins closest to the power plug. If you're powering the board through the USB, the jumper should be on the two pins closest to the USB plug. This picture shows the arrangment for powering the board from the USB port.

</p><h3><a name='toc8' id='toc8'></a>Why does my Diecimila take such a long time (6-8 seconds) to start my sketch?</h3>
<p>Some of the Arduino Diecimila boards were accidently burned with the Arduino NG bootloader. It should work fine, but has a longer delay when the board is reset (because the NG doesn't have an automatic reset, so you have to time the uploads manually). You can recognize the NG bootloader because the LED on pin 13 will blink three times when you reset the board (as compared to once with the Diecimila bootloader). If your Diecimila has the NG bootloader on it, you may need to physically press the reset button on the board before uploading your sketch. You can burn the correct bootloader onto your Diecimila, see the <a class='wikilink' href='http://arduino.cc/en/Hacking/Bootloader'>bootloader</a> page for details.

</p><h3><a name='toc9' id='toc9'></a>What should I do if I get an error when launching arduino.exe on Windows?</h3>
<p>If you get an error when double-clicking the arduino.exe executable on Windows, for example:
<p class='vspace'></p><p><code>Arduino has encountered a problem and needs to close.</code>
<p class='vspace'></p><p>you'll need to launch Arduino using the run.bat file. Please be patient, the Arduino environment may take some time to open.
