Hi,
Ive been trying to figure out my EC for couple of days, but no luck.

I found EmbeddedControl in DSDT but no way of figuring what addresses do anything,
it is quite strange. Here is DSDT from RWEverything
DSDT.zip

With ec-probe.exe i found out that 156,157,158 change with fan speed, most often.
I think 156 if CPU temp, but that does not correspond with DSDT, which has a register:
Offset(0xD7), //Offset(215),
CPUT, 8,
but everything around 215 is zeroes...

Im missing something and my head hurts :)

Here are EC dumps with low and high fan speed:
EC6662-lowFan.zip
EC6662-highFan.zip

Regards

It appears its EC is winbond w775l, based on some block schematics, but again no luck. No datasheet to be found....
