Still need to know what make/model CPU it has, and what cpufreq drivers it uses .. can you post the whole dmesg.boot ?

If things aren't too big they're perhaps better posted inline, so I'll quote a few bits that look a bit strange regarding temperatures: > acpi_tz0: _CRT value is absurd, ignored (-273.2C) .. > hw.acpi.thermal.min_runtime: 0 > hw.acpi.thermal.polling_rate: 10 > hw.acpi.thermal.user_override: 0 > hw.acpi.thermal.tz0.temperature: 56.0C > hw.acpi.thermal.tz0.active: -1 > hw.acpi.thermal.tz0.passive_cooling: 1 > hw.acpi.thermal.tz0.thermal_flags: 0 > hw.acpi.thermal.tz0._PSV: 135.0C <<<--- > hw.acpi.thermal.tz0._HOT: 90.0C <<<--- > hw.acpi.thermal.tz0._CRT: -1 <<<--- > hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 > hw.acpi.thermal.tz0._TC1: 2 > hw.acpi.thermal.tz0._TC2: 5 > hw.acpi.thermal.tz0._TSP: 50 > hw.acpi.cpu.cx_lowest: C1 The _PSV (passive cooling) temp is 'absurd' also; it certainly should be lower than _HOT - which looks possibly right at 90C - and _CRT (critical shutdown) definitely should be there, probably <= 100C. Is it running the latest available BIOS update? > dev.cpu.0.freq: 250 > dev.cpu.0.freq_levels: 2000/35000 1750/30625 1500/26250 1250/21875 > 1000/17500 750/13125 500/8750 250/4375 > dev.cpu.0.cx_supported: C1/1 C2/57 > dev.cpu.0.cx_lowest: C1 Maybe more about these after seeing your dmesg.boot .. cheers, Ian --0-1723867758-1273421476=:22612--
