A couple of weeks ago I was using my Inspiron 17R laptop and everything was working fine. Now when I attempt to boot up the laptop the three LED indicators above the number pad light up. In sequence and the computer stops booting. In terms of the LED indicators there are two gears, a wrench and a monitor with a line going across it diagonally. I don't hear any boot tones nor do I see anything indicated on the screen. I believe the machine is going through the POST Test before shutting down. Because the LED indicators (I don't know what you call them) are lighting up in sequence. I don't have the actual specs on the computer handy. Here's what I know. 500 GB 540 RPM hard drive 6 GB of RAM one optical drive second-generation Intel core I5 Processor I know I have not been able to provide terribly specific information, but I would appreciate any advice anyone might have.
