I'm trying to troubleshoot a Sony VAIO VGN-FS620/W notebook computer. With AC plugged in, or on battery, or on AC with no battery connected, the the power light goes green, you can hear some activity inside, and the Lock lights (Caps, Num, Scroll) stay solid green. Otherwise, there is not activity- no video at all, no signs of post, and no hd activity.
I'm wondering if the Lock lights act provide error codes like they do on Dell laptops (I haven't worked on many VAIOs). Does anyone know if these lights indicate errors, and where to find out what they mean? Otherwise, I will continue with standard troubleshooting procedures (swap out RAM, check for external video output, etc). If you don't know about the error codes, but think you may know what's going on here, feel free to comment.
