Question. You mentioned the light comes on.

Do you get a startup chime?

After pressing power, how long until it comes on?

I just noticed that my light comes on but not right away. The TAM chimes then its still about a second before it comes on. Like the light is almost a hardware check indicator more than an actual power light.

edit: After pulling the cache again my TAM failed to boot. I had to re-seat the RAM and it boots fine now.
