T410 - unknown device again!

2012-08-28, 14:08 PM

OK - got unknown device on T410 laptop which I beleive is the Power Mgt driver. On the driver download page for the model 2537 - there is power management app download but no PM driver download !!

 

http://support.lenovo.com/en_US/downloads/default.page#

 

I have downloaded the app and installed rebooted and still get this unknown device

 

unknown device = ACPI\IBM0068\%&2890D699&0

 

Any ideas ?

 

Joe.

let us dig around a bit.

 

cheers.

 

edit: please have a look at this: http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-4gxpeg

same driver in the t420 matrix at this link: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS014939

not sure why it's missing from the t400 and t410 matrices even though they're all listed as supported systems.
