Yes, that's the primary reason. Our initial batch of XO-1.5s have an inefficient heat spreader. They've been burning out, and replacing the motherboards is getting expensive and time consuming. We'd like to detect potentially faulty units early, and recommend a heat spreader change for them. As a thought - maybe we should be identifying the serial number as well? > I don't think it is worth doing this test for the purposes of flashing > the XOs. The built in throttling will work fine.

It might be true that the XO can't get damaged from flashing, but the symptoms at runtime are random and are difficult to diagnose. I think that forcing a heat spreader test can provide a warning to the user and allow them to do something before any damage or annoying behaviour can begin. _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
