How to change battery auto-dim

I was wondering how i can change the auto-dim feature on my Sager NP5793. I did a couple of google searches trying to find an answer, and the closest i got was in the acer section of this forum. http://forum.notebookreview.com/showthread.php?t=205743

I have the same problem as the OP of that thread, down to the end of the thread, i also dont have a brightness setting on my power options or advanced settings of the power options. Anyone have any ideas? Im running windows 7 beta, specs in sig

 

To confirm, your power option screens don't look anything like these? I'm also using Windows 7.

 

my advanced settings looks exactly like that, except the only option shown under display is "Turn off display after:" and i dont have those brightness sliders on the power options...

 

i think i found the problem, i did a windows help search and it told me i should update my drivers for my monitor...however when i go to the device manager and search for a new driver online for my "Generic PnP Monitor" it comes back saying i already have the best driver software installed

 

Hmm, well would Nvidia's driver have anything to do with the available options? What version are you using?

 

im not completely sure, because i downloaded so many different ones because most of them wouldnt install, giving me this error:

Code:

the nvidia setup program could not locate any drivers that are compatible with your current hardware. setup will now exit

even the nvidia geforce 9800GTS driver for the windows 7 64 bit beta...which is exactly what im using...i even tried uninstalling all display drivers to install it and it still wouldnt install...so finally i tried the nvidia laptop driver update for windows vista 64 bit downloaded here:
http://www.nvidia.com/object/geforce_notebook_winvista64_179.48_beta.html

and there is no brightness option in the nvidia control panel..and its version 2.2.275.00

i just checked, i have the nvidia geforce 9800M GTS driver version 7.1511.7948 released 1/30/09

 

Unfortunately the brightness setting for the 5793 (M570RU) is hardware only and not controllable through software.

And you're not using a 9800GTS, you're using a 9800 M GTS, they're very different

 

oh ok...so there is no way to change it?

and yea, i just figured that out about an hour ago lol, thanks though

 

unfortunately, you just have to manually adjust the brightnes when you go onto battery/ac if it is not to your liking.

 

efffff.....oh well...thanks for the info

btw, i wouldnt even be THAT bothered about this if the power cord didnt fall off every 5 effin minutes and dimmed to 30%...but w.e

 

I've never had an issue with the power cord falling out with either of my psu's. Have you contacted your reseller about maybe getting a replacement psu?

 

no, i dont think it would make a diff, i think thats just how the psu is, not a defected one..and i move my laptop around, its not on a desk all that often, which contributes to it falling alot
but im going to send an email to sagers technical support asking about it just in case

 

As I say, I don't have that problem with either of my psu's on my 5793 (equivalent), so it's not a standard issue.

 

ok, i emailed the technical support, they havent responded though
