Power manager issues

Hello,

 

I am running Vista Home Premium 64-bit on a T61 with all the latest drivers and the latest version of power manager (2.36).  I have noticed that when the system is on battery, the screen will go blank/turn off every few seconds and then come back on.  Also if I touch the touch pad sometimes that will trigger the screen to go blank/turn off.  This behavior stops once I plug the laptop into an AC power source.

 

I am wondering if there is any solution to this problem.  It is very annoying and forces me to uninstall the power manager if I want to use the laptop on battery power alone.

 

Thanks for any information.

 

-Paul

Hello Paul,

 

check in Powermanager if it is allowed to run down display frequence for power saving purposes.

 

Also check Ati Control Center, if option is enabled over there.

 

This behavior is a feature, not a failure.

Re: Power manager issues

Hi Andreas,

 

Thanks for your response.  Before you replied I tried removing the power manager and the behavior continued. It continued even with the interface & power management drivers removed.

 

I am trying another clean install now to try to narrow down where things start to go wrong.

 

Stay tuned.

Re: Power manager issues

Hello Paul,

 

please be patient, Thinkpad´s have got well coded and more complex software.

Please ask here before uninstalling, otherwise you can easily mess up your system.

 

Just one hint.

Never touch a running system and do not update, if it´s not necessary.

Re: Power manager issues

Thanks Andreas.  Regarding a clean install, does it matter what order the drivers are installed in? for instance should I install the ACPI Power Management driver before the graphics driver? and i'm wondering if I need to install the "System Interface Driver" (whatever that is).

 

My system is not a production system so I don't mind re-installing the OS every now and then to learn about how things work.

Re: Power manager issues

Hi Andreas,

 

I found the issue.  It was caused by the power management settings in the Intel video driver.  Once I disabled those then the laptop would behave normally under battery power.

 

Thanks for your help.  Yes, I was already following the great clean install guide you mentioned.

 

Regards,

-Paul
