While the CPU is not under too much stress, I can get a good 30-45 minutes of worktime before the computer becomes worryingly hot. I don't think that flashing a BIOS requires a lot of computations, and I don't recall it taking too long either, so it'd be a low risk. The consequences are more daunting than the chances of it happening.
Indeed it seems safe to attempt then.
Sorry, it has been some time since my last message here. I have tested flashing the BIOS, it did not seem to change anything to the issue. I also tried flashing the BIOS and then booting immediately on a live USB (ubuntu, since I could not get openSUSE to boot), the fan didn't spin fast enough to prevent the computer to grow abnormally hot. I have also noticed in the past weeks a much decreased battery life, from more than 5 hours with a full charge down to less than 2 hours. I am mentioning it only because it could be another symptom of the same ACPI problem, but there are a lot of other possible explanations: - usually I don't reboot the computer for weeks, rebooting it every 30 minutes (or more often when testing kernel settings) puts more stress on the battery; - exposure to high temperatures could have aged the battery prematurely (the battery is only 15 months old, the original one died already). For what it's worth, I've been monitoring this battery since day 1, and neither the max charge nor current voltage seem to have dropped in may. But I'm not sure how much I should trust the reports from this battery. Anyway, the problem has been here for more than a month now, and I am not able to reliably work-around it (actually, neither reliably nor at all, at the moment). I have ordered a replacement computer for now. I will probably not attempt to open the laptop post-mortem, because I wouldn't know what to look for to investigate a hardware failure... If someone has more ideas of things to try about this issue, I'm still interested. After all, I had plans for the afterlife of this computer, but they relied on uptimes longer than 45 minutes...
