My friend, I've been a senior technician for over 10 years now, I've gone through the manual on numerous occasions. Unfortuantely I'm the only technician in my company, otherwise I would've asked for assistance. I do understand that you are only the end user, and the easiest thing to say is "check the manual", but that is why we have this site, so that technicians and engineers can help and assist each other when all else fails and the manual doesn't help anymore.But thanx for trying to help, I really appreciate it. God bless!

For what it's worth, on my first and only experience with this code, it was the DCPU. I was able to get the machine to code more than 50% of the time as it was coming out of power save mode.

I replaced the DCPU and soon after the code returned. Now I'm nervous, thinking I've wasted a DCPU and I took a long time to make that call in the first place. Long story short, 1st replacement DCPU was at fault too, replacing it again fixed the problem.
