Chosen Solution

Ran Apple Hardware Test and on my G4PB 1.33GHz machine Got error code: 2GMC/5/16:built-in Anyone know what it means?

IIRC that code refers to a logic board problem with a heat sensor but I’m not 100% certain of that and can’t find my data source. Ralph

so what - they did not trade it then? And did not know what it means either?
