多谢多谢,有救了
请教temp1_input和temp2_input分别指哪个温度,尽管从经验上看temp2_input是cpu温度
这个问题似乎比较难回答,可能因机器不同而异。也许grep 一下kernel source 匹配temp1_input,会有答案。
比如,
(http://www.thinkwiki.org/wiki/Thermal_Sensors)
ThinkPad R51
The ibm-acpi documentation includes the report by Thomas Gruber:
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 Mini-PCI
0x7A 3 HDD
0x7B 4 GPU
0x7C 5 System battery
0x7D 6 UltraBay battery
0x7E 7 System battery
0x7F 8 UltraBay battery
0xC0 none ?
0xC1 none ?
0xC2 none ?
[edit] ThinkPad T40
The location of one of the sensors is identified here.
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 System board under rear left corner of Mini-PCI module
0x7A 3 ?
0x7B 4 GPU
0x7C 5 Battery
0x7D 6 n/a
0x7E 7 Battery
0x7F 8 n/a
0xC0 none n/a
0xC1 none n/a
0xC2 none n/a
[edit] ThinkPad T43, T43p
Found by Shmidoax using cooling spray to cool down components and observe the effect on the sensors.
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 Between PCMCIA slot and CPU (same as HDAPS module)
0x7A 3 PCMCIA slot
0x7B 4 GPU
0x7C 5 System battery (front left = charging circuit)
0x7D 6 UltraBay battery?
0x7E 7 System battery (rear right)
0x7F 8 UltraBay battery?
0xC0 none Bus between Northbridge and DRAM
0xC1 none Southbridge, WLAN and clock generator (under Mini-PCI card, under touchpad)
0xC2 none Power circuitry, on underside of system board under F2 key |
