Acer Epower

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.

 

Maybe you disabled somehow ePower management to start with system start up.
Anyway try reinstalling ePower management,go to Acer download pages and download it for your model.

 

Thanks Max for your response.

Unfortunately, that is not the case. As a matter of fact this model is factory-shipped without the ePowerManagement feature.

 

i have the same problem

 

James.

I have already solved my problem and hope my solution applies to yours too.

I found out that I was using a hal.dll (hardware abstraction layer dynamic link library) for a standard PC without ACPI features.

I had to find out what was the right one (in my case halaacpi.dll, which is for uniprocessor ACPI-enabled PCs), boot with an alternative hal.dll (I created an alternative extra boot option in boot.ini with switch /HAL=halaacpi.dll), reboot using the mentioned alternative boot option, rename the current hal.dll, and copy halaacpi.dll to hal.dll (all of these files reside in the \Windows\System32 folder), reboot and restore boot.ini to its original state.

There is a considerable body of knowledge in the Internet regarding hal, its relationship to ACPI and boot options. You may want to go through all of it before trying this procedure.

Hope it does the job.

Regards.

 

Sorry, I may induce misinterpretation by saying "...all of these files reside in the \Windows\System32 folder..." because I actually meant "..all of these hardware abstraction layer dynamic link libraries reside in the \Windows\System32 folder..." Boot.ini is usually in the root directory.

 

thanks JackDavid,
your solution solved the problem
