I'm having the same problem with my Inspiron 600m. It just began last night, same problem. It froze last night out of nowhere, I restarted and it froze again within a minute or two. After that when I tried to power on the Caps Lock light would flash a few times and then everything went off.
I checked the manual and see nothing about this error code. Does anyone know what this could be? I tried calling tech support but have been on the phone for about an hour now.
Apparently the Cap Lock blink means bad CPU/Motherboard. It's likely considering how hot the laptop gets when it's running so I'm not too surprised.
I thought it could have been a memory issue too as I was getting memory-related errors last month, but they stopped.
I HIGHLY recommend any customer buying a new Dell to get the Completecare warranty as long as they can get it for. I've already had to send my system in twice, and the service and repair time is quite acceptable.
I'll give an update once I get the laptop back.
Got the laptop back, and it's working perfectly now... was indeed the motherboard.
I also got it back in amazing time, mailed it out on Tuesday, got it back today (Thursday). Can't beat service like that, cheers Dell.
