Power still supplied to motherboard after Win7 shuts down
I hope this is in the right place; if not, sorry about that.
Over the last weekend I installed a new hard drive into my system, and on that drive installed Windows 7 Ultimate x64. Over the past week I have been tweaking my settings, resolving issues, and installing programs.
So far everything is working fine, except for the fact that when I shut down, there is still some power being supplied to my motherboard (NumLock indicator does not turn off, and if I open the case the power LED on the motherboard is illuminated). This does not happen when I shut down from Windows XP (I have a dual-boot configuration; XP is on my smaller hard drive).
Here are the things that I HAVE done:
1. I have gone into my BIOS and disabled all the relevant power management settings (as far as what devices can wake the system, etc.).
2. I have gone through my Windows 7 power management settings and disabled/changed all settings that seemed relevant.
3. I have gone through my device manager and made sure that, for all devices that have a power management tab in their properties, the check box that says something like "Allow the computer to turn off this device when shutting down" (or something like that) is selected. Yes, even for the firewire port. There are some items for which the check box is greyed out and cannot be selected (such as the keyboard).
Here are the only things that I think may have an impact that I have NOT done:
1. Installed the chipset drivers for my motherboard in Windows 7. I have not done this because: a) other than powering down, everything else works fine; and b) I am not sure which driver package I should install (due to the mixed northbridge and southbridge chipsets on my motherboard).
If anybody could help me out with this issue, I would be most appreciative. I have been doing some googling, but most other people seem to have resolved the issue by selecting that check box for their firewire port.
I'd rather not have to boot into XP just to shut down, and I'd rather not have to install drivers that may have potentially destabilizing effects on my system, if I can avoid it.
Thanks in advance for any advice!
