I've got some more things you guys might want to look at. Googling for 'spontaneous shutdown' and similar terms, I found the HP business customer discussion group, which contains quite an interesting thread about HP Pavillions (ZT1130/ZT1145), the posting by a a Robert J. Koening being especially insightful. See the following URL: http://bizforums.itrc.hp.com/cm/QuestionAnswer/1,,0x3009237a4bc6d611abdb0090277a778c,00.html To quote from it: "[...] I summarize the substance of the one of the other threads I read. It was concluded by all that it was an overheating problem. People aimed small fans at their hp laptops and claimed to have remediated the problem. Others put tongue depressors under their laptops and removed piles a paper around the lap top and claimed to have stopped the uninvited shutdowns by prompting better ventilation. But there was no compelling epiphany to explain the problem. However, I got the sense that the problem was more a false high-temperature reading than a real high-temperature problem. There was a lot of talk about whether the automatic fan was working when the intrusive shutdown occurred. The shut downs did not necessarily seem to take place when the fan was working. At the end of day, it was suggested by the hp overseer (who watches us writhe for a while before finally jumping in) that the new BIOS will cure the problem. [...]" I'm not sure what ODM is supplying Hewlett-Packard for this machine, but as we have learned before, some Omnibooks seem to be Compals as well so I would not rule out the possibility that the Pavillion ZT11xx are as well. Maybe the owner of one on this list can find out? I downloaded a BIOS image for it, extracted and ran strings over the all.rom file, but it seems to look very different, except for the Insyde signature on both of them. Incidentially, Insyde Software seems to be providing ACPI firmware for ODMs like Compal. What a coincidence.
