Hi,
I did a BIOS upgrade on my E20 - 4220-CTO to 5JKT55A and I started seeing these messages in my System Event log ->
"Idle power management features on processor 0 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
"Idle power management features on processor 1 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
"Idle power management features on processor 2 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
"Idle power management features on processor 3 in group 0 are disabled due to a firmware problem. Check with the computer manufacturer for updated firmware."
The messages occur on each reboot.
I upgraded to the latest bios 5JKT56A and I get the same messages.
I was not getting these error messages on BIOS level 5JKT47A(ship from lenovo with this level).
I updated my BIOS as it was suggested on the lenovo site before doing the win7 SP1 update. Note - I got the error before and after the SP1 update so it's not related to SP1.
I have not see any additional issues, just the messages in the event log on each boot.
Any ideas?
Thanks in Advance!
