I recently did a clean install of Windows XP Professional after running Windows ME. Before I could install XP, I had to upgrade my BIOS software so it would support XP. After doing this, I found that my computer would no longer go into standby properly, neither under Windows ME, nor after I installed XP Pro. The PC would go into standby, i.e. the screen would go off, but the fans in the PC would continue spinning at their full rate, not at a slower rate when I had my original BIOS software. Does anyone know why this is? I tried disabling power management in CMOS, but this had no affect. I also tried uninstalling the ACPI Computer from Device Manager, but I can't get it back again, after installing Standard PC, which will not allow Standby anyway!
If your BIOS supports ACPI mode, it will be found under "Advanced BIOS features". Use you arrow keys on the keyboard to scroll down to it and click on the "Enter" key, highlight the ACPI and click on enable.
Turn off "Advanced power management though if you do use ACPI. j.
wx622, when you use the Del. key to boot into your BIOS. The first heading should be.
Standard CMOS features.
Then directly underneath that should be.
Advanced BIOS features.
If you look further down the page, you should find "Power Management setup".
This is the one you need to high-light and then press the enter key. A new screen will open and if you scroll down the list there will be a setting for ACPI or similar. This is the one you need to highlight and then "Enable".
If this is not being shown on your board, I can only think it's because the board is an older one and doesn't offer the feature.
Have another look in the BIOS but also wait for further advice from others to see if there is an answer to this. J.
I wouldnt turn it on while there is an OS installed may have funny side affects best to enable it when the hdd has been formated before you install an OS then it will find it and install the drivers required
