SwingKid Posted August 12, 2007 Report Share Posted August 12, 2007 * Laptop Make/Model * Graphics Card -- device id if known * Current Driver Version * Last Useable Driver Version * Operating System * An accurate description of the issue at hand - Samsung R70 - Nvidia 8400M GS - 158.24 Modded INF - 158.24 - Windows Vista Home Premium - I installed the modded INF due to Battlefield 1942 being unplayable (no crosshairs etc etc). The modded INF fixed all of those issues but a new one has occurred. The screen is darker than usual - as it goes when the laptop is running on battery power. It's definitely plugged in (duh) and I've checked the power plans etc to see if they've been adjusted. All of the brightness/contrast levels under the Nvidia control panel appear to be the same as before. Any ideas why this may be occuring?

®®® Posted August 12, 2007 Report Share Posted August 12, 2007 Finally someone who read the sticky! Thanks. Does it also occur when you start a game aka GPU intensive application? From your description is definitely that the GPU is put in PowerSaving mode by VISTA (or the driver) as it has nothing to do. It might be good idea to have a look at the original INF provided by Samsung for specific settings and use these Samsung custom values in our modded generic INF. Here's a short reference of Tweaks to look after in the original INF. These affect PowerSaving.

SwingKid Posted August 12, 2007 Author Report Share Posted August 12, 2007 I can't find reference to any of those values in the original INF. I saved it as a backup and can see no reference. Is it possible that i'm looking in the wrong place? Quote Link to comment Share on other sites More sharing options...
®®® Posted August 12, 2007 Report Share Posted August 12, 2007 No. But welcome to NVIDIA's world introducing and changing values and settings in the INF like we do underwear. The original Samsung driver/INF is probably from the pre-150s series, that's why you can't find. Was worth a try. DoublCheck or play around with the ControlPanel settings i can only advise. I don't run VISTA, so no real help, maybe somebody else can jump in. Quote Link to comment Share on other sites More sharing options...

sai187 Posted September 8, 2007 Report Share Posted September 8, 2007 Since I installed the Nvidia GFX drivers for my 8400M (Samsung Q70) I can't change the brightness of the monitor anymore. Neither the Fn keys work nor the samsung utility does. No matter what version I use its the same issue. I tried installing the drivers from the Samsung support site but the archive seems to be corrupt since I can't extract it. So I tried different versions from the main site here and it's the same problem with all of them. Anyone knows a work around or a working driver? Otherwise I need to contact Samsung and ask them to fix the download or somethin.. thx in advance..sai Quote Link to comment Share on other sites More sharing options...
