"I was having trouble with" joke

I was having trouble with my computer. So I called Alex, the computer guy, to come over. Alex clicked a couple of buttons and solved the problem. He gave me a bill for a minimum service call.
As he was walking away, I called after him, ''So, what was wrong?''
He replied, ''It was an ID ten T error.''
I didn't want to appear stupid, but nonetheless inquired: ''An ID ten T error? What's that... in case I need to fix it again?''
Alex grinned... ''Haven't you ever heard of an ID ten T error before?''
''No,'' I replied.
''Write it down,'' he said, ''and I think you'll figure it out.''
So I wrote out... I D 1 0 T
