Aspire 5040 - Power management features gone.

I have lost the ability to configure the control panel's power management options on an Acer Aspire 5040. For instance I just can't configure what to do when the power button is pressed, display the battery meter on the taskbar, or adjust when to go to inactivity when running on batteries. All those options are gone now.

Your support will be utterly appreciated.

I lost the EPower management settings on my Acer Aspire 5102. I think it happened when it froze up and some files got truncated. Acer advised a factory restore from the DVD's you made or the hard drive recovery. I have done each once and it did restore all the original software to a functional state. If you still have your drive in the three partitions the data on D is untouched in the recovery process so move anything you want to keep on C drive to D drive before the recovery restore.

Thanks a lot for your response, Pegazuz. I stubbornly resisted restoring to factory settings because I have already done that before (twice) and it's a pain in the neck to restore all of my previously installed applications. I chose to workaround the hard way (manually determining and setting up the right hardware application layer dynamic link library). The good news is I already solved my problem.

That is great you were able to do it. I spent several daystrying to restorefunction by re-instaling the EPower software and searching for files to replace those that seemed missing but couldn't come up with any fix. Maybe you could post some hints here for the next guy that has this problem on how you fixed it cause I am sure it will happen to others.

I welcome your invitation and gladly share those tips that may help other experiencing similar problems. There is an extensive body of knowledge regarding power management, Windows boot options and hardware application layer dynamic link libraries over the Internet. Hence I'll skip those details and directly enter to the step-by-step procedure that worked for me. First I must tell that the root cause was a corrupt hal.dll that I replaced with one I found in the I386 folder without knowing it didn't support power management. 1. I added a boot option in my boot.ini file with a switch to load a different hal (halaacpi, which is the library suitable for uniprocessor ACPI-enabled computers). The resulting file looked like this: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(2)\\WINNT [operating systems] multi(0)disk(0)rdisk(0)partition(2)\\WINNT="Microsoft Windows XP Professional" /fastdetectmulti(0)disk(0)rdisk(0)partition(2)\\WINNT="Microsoft XP Professional - Alternative HAL" /HAL=halaacpi.dll 2. Rebooted and selected the recently added boot option. 3. Renamed hal.dll to hal.old (or whatever name is easily detectable for rollback purposes in case this procedure does not work). 4. Copied halaacpi.dll to hal.dll. 5. Removed the boot option inserted in step 1. 6. Rebooted and voilá!
