Re: My first portable - any help appreciated!

First milestone reached. Got the DC to run off my battery.

At first I thought I fried my board because when I connected battery to the pico the dc light turned on but the drive wouldn't spin even when I would hold down that little black lever that tells it when the lid is down. Turns out my ...
