There is something loose in it, or some broken solders that are creating problems only when the heat increases. That's a tough problem to troubleshoot. I'm not sure but does the Lombard have a processor daughterboard snapped on the motherboard? If so, that would be the first thing I would try to fix, e.g. removing the daughterboard and putting it back while making sure it is solidly in place. Then, there is something with the power. A connector or maybe an hairline crack in the AC/sound board or something like that. Have you tried a different adapter? -Laurent. -- ============================================================================ Laurent Daudelin AIM/iChat: LaurentDaudelin <http://nemesys.dyndns.org> Logiciels Nemesys Software mailto:[EMAIL PROTECTED] CLM /C-L-M/: [Sun: `Career Limiting Move'] 1. n.
