I have been using Ubuntu since 1yr on my Compaq Presario V3029AU Laptop. I have been facing this very common problem and not been able to find a solution,
Critical temperature reached (100C) shutting down..
This doesnot happen always.It happens only when i am running a CPU intensive job like kernel compilation,or worse when I am playing Mafia on Wine.
Has anybody really solved this problem? I came across several posts saying that this was a bug in ubuntu kernel, but I have tried newer distros --gentoo ,backtrack all shutdown giving the above message.(In gentoo it is worse, I cant compile X.. and you have to compile everything to get things working)..
I have come to conclusion that this is a bug in kernel, even with the option acpi=off ,my laptop switches off with no messages wat so ever.
Users of Compaq presario V3029AU ..Have u found any solution? This has crippled me from playing games or compiling stuff in linux
