It appears if I kill or do not allow the "persistencethread.exe" process to run, the computer is able to maintain the screen brightness I choose w/ the brightness adjustment function keys on the netbook.</P> Wed, 29 Jul 2009 02:25:27 GMT idata 2009-07-29T02:25:27Z https://community.intel.com/t5/Graphics/Graphics-Accelerator-500/m-p/394052#M30354 <P>I have a Graphics Accelerator 500 on an Acer Aspire One 751h running Windows XP SP3. My problem is that when I adjust the brightness, the adjustment holds for about 15 seconds and then it goes back to the standard setting.</P><P></P><P>I have made sure I have the latest drivers installed. Is anyone else having this problem, and does anyone know a solution?</P> Wed, 22 Jul 2009 03:22:24 GMT https://community.intel.com/t5/Graphics/Graphics-Accelerator-500/m-p/394052#M30354 idata 2009-07-22T03:22:24Z https://community.intel.com/t5/Graphics/Graphics-Accelerator-500/m-p/394053#M30355 <P>Not sure if it will help anyone else, but I figured out a solution.

It is version 6.14.11.1012 of the Intel driver for Windows XP Pro.
