P4C800E - Howto shutdown fans on standby?
My system has 2 chassis fans, and a Prescott CPU, so the combination is
quite loud. Is there a way of shutting down some or all the fans when the system is in standby? I can't use hibernating mode as I need the system to wake up very fast. |

Ingredients for this to work would be: 1) ACPI enabled in the BIOS. (And, no, I don't know if your ACPI 2.0 setting makes a difference or not. My assumption is the motherboard defaults should be good enough. 2) OS installed with ACPI HAL (hardware abstraction layer) 3) A copy of dumppo.exe ftp://ftp.microsoft.com/Products/Oem...cpi/dumppo.exe From a dos prompt: dumppo.exe admin /ac minsleep=s3 There is a bit of info in this thread: http://forums.pcper.com/printthread....3&page=3&pp=15 That should stop the fans. In S3 state, the processor is shut down, video card powered down etc, only DRAM is still powered, in order to maintain refresh cycles. Note: The Microsoft site isn't responding right now, and I don't know of another site with the executable. Size is 13072 bytes for the file. OK, found another site. Only this file is 13584 bytes ? An extra 512 bytes ? Makes you say hmmm... http://www.bellamyjc.net/download/dumppo.exe I hope you can reach ftp.microsoft.com later today. HTH, Paul |

Enable "Suspend to Ram" in the BIOS, and then either reinstall XP or use the
DUMPPO.EXE mentioned in an earlier post. "Shaw Goh (NetPlus Micro Computers)" wrote in message ... My system has 2 chassis fans, and a Prescott CPU, so the combination is quite loud.
