Power Manager Error after System Update

2009-02-16, 23:56 PM

Just got a new T500, just got all my apps installed and everything was working great. The last thing I did last night was run a "System Update".  Now I have two problems:

 

1) When I log in I get a "Power Manager has stopped working" error.

2) Switchable graphics won't switch.

 

Anyone seen this, and any ideas how to resolve it?

switchable graphics option is found in power manager. If the program has stopped working I would advise uninstalling Powermanager and Reinstalling it from here. Make to follow the installation instructions on the download page

I too have the same issue with switchable graphics.  All was working fine until upgrade to Power Manager 2.42.  I do not encounter the PM has stopped working problem.  I unistalled / reinstalled it mannually and it still does not work.  May try old version of PM.

FYI, I tried an uninstall of the Power Manager and Power Manager Driver that System Update had given me, and I then manually instaled the versions from the driver download site (Power Manager V2.42 from 2/12/09).  I was surprised that this version was HIGHER than one that System Update gave me, which I am pretty sure was V2.38?).

 

Anyway, with V2.42 I no longer got the error on login, but I found that "Switchable Graphics" just would not switch! (no apps running, no external monitors connected etc.)

 

Luckily for me I had done a full system backup immediately before using System Update. I actually wound up restoring the entire system to get everything back the way it was in before I used System Update.

 

So I'm now back on Power Manager V2.35 which is what shipped on the system I received last week ( I wonder why they're shipping this old version???) and now everything seems to be working fine.

 

I have disabled System Update and don't intend to use it again!

Version 2.42 is working for me now - at least in the undocked mode.  I the only change I made was to undock the computer????

My power manager was inop too (Power Manager has stopped working error on boot up), I just installed version 2.42 and all is well again, the previous version from an update on 10-Feb-2009 was 2.41a and was what caused the error for me.
