Had a strange effect on my Thinkpad lately – since a few days Intel AMT BIOS messages appear occasionally during boot-up:
Intel(R) Management Engine BIOS Extension v4.0.4.0007 Copyright(C) 2003-09 Intel Corporation. All Rights Reserved. Intel(R) ME Firmware version 188.8.131.524 Intel(R) AMT enabled Intel(R) AMT configuration in progress Inventory Update Field Replaceable Unit List: Intel(R) AMT Table Valid Media List: Intel(R) AMT Table Valid SMBIOS Table: Table Mismatch - Updating Intel(R) AMT [Complete] Setting New Table Fingerprint
I had Intel AMT deactivated before and I’m not using the fingerprint sensor. The AMT features seem to activate themselves occasionally in the BIOS so my best guess is that the CMOS battery is dying… Will replace it and see if the strange effect disappears.
Update: I’ve replaced the CMOS battery and so far have not experienced any AMT messages. (Well on the first boot there actually was one telling me that the SMBIOS table was rebuilt.)
