<div dir="ltr"><div><div>Hi everyone, <br><br></div>The current driver linux/drivers/macintosh/therm_adt746x.c does not take the HDD BUTTOMSIDE sensor into account. It actually should as the 12" Powerbooks and IBooks are build in a way that the airflow cools the harddrive and components around it. Actually there are air intake openings just beneath the Harddrive. If you experiance hot enviromental temperatures as I did in summer on certain occations, you will find out that in MacOSX the fan spins up while it doesn't in linux. As this probably causes harddrives, and maybe other components to fail early I think this should be regarded as a fix to a severe bug.<br><br></div><div>Hence, I created this patch for single fan 12" Albooks, Ibooks etc. <br><br></div><div>Further I changed the output /sys/devices/temperatures so that all 3 sensors are readable from this locations. The output is furhter multiplied by 1000 in order correspond to the ranges printed by other sensor readings. ( This also makes the readings monitorable with tools such as xosview ) <br></div><div><br></div><div>I sign this contribution as demanded, and hope that it will help keeping several Powerbooks and Ibooks out there running a bit longer: <br><br><pre>(a) The contribution was created in whole by me and I
