Just have a look to your trip_point: mgisbers@mars ~ $ cat /proc/acpi/thermal_zone/THRM/trip_points critical (S5): 95 C passive: 87 C: tc1=3D1 tc2=3D5 tsp=3D10 devices=3D0xdff72dc4 When reaching 95=B0 my computer starts to shutdown fast. I found more Information on=20 http://acpi.sourceforge.net/documentation/thermal.html Maybe it helps you too. =2D-=20 Michael Gisbers http://www.lugor.de --nextPart2028351.5Bam9kFe1l Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5-ecc0.1.6 (GNU/Linux) iD8DBQBFH+1Ygp6ccyw//rwRAqRgAJ4lZisftIHf9FeJTw2jRppneNIrcgCgtqqy 70X0noX772Q3cjhgtrPvA2A= =x8vm -----END PGP SIGNATURE----- --nextPart2028351.5Bam9kFe1l-- -- gentoo-user@gentoo.org mailing list
