My Vostro suddenly shut down and wouldn't power up. I removed the monitor, printer and unplugged the power cord. Waited 15 minutes and plugged it back in, tried to power it on and only got a solid amber light. The unit did updates 2 days ago so I was wondering if that had anything to do with the crash. I took the cover off of it and blew the dust out and everything looked alright. Any suggestions on getting it to turn on would be appreciated.
