Temporarily Disable Power Management

April 26, 2008

I'm in the process of updating the BIOS and Embedded Controller programs on

a ThinkPad (required in this case as part of a miniPCI wireless upgrade).

The BIOS upgrade went fine, but I aborted the embedded controller upgrade

when the final message before the actual flash came up: "Exit now if Power

Management is enabled."

I take it this means ACPI. To figure out how to disable it, I checked both

device manager and the BIOS settings. Device manager shows various

subcomponents whose drivers can be uninstalled. The BIOS has a "Power"

category, with subcomponents where it looks like you can only make

adjustments to their operating peramemters. I could find no reference to it

in Services under Administrative tools.

Is there a "non-segmentized" listing for this and is there a way to just

temporarily disable it?

Re: Temporarily Disable Power Management

It looks like you can uninstall the driver in Add/Remove, so it doesn't seem

that big a deal to just reinstall it after the flash.
