New Mac Mini (2011) takes a long time to WAKE UP

[LincolnsiPod]

For some reason whenever the Mac Mini goes to sleep, it takes about 15-20 seconds for it to wake up. I can think of only a few reasons for this:

• I'm using a PS/2 mouse and keyboard, connected via an adapter to a single USB port. Works fine, but I'm not sure if this type of set up could cause sleep related issues.
  
• I'm using an 19 inch HP monitor (model w1907) connected via an HDMI to DVI adapter. I've read elsewhere that certain adapters can cause the issues I'm seeing (specifically the Mini DisplayPort to Dual-Link DVI Adapter) but none regarding this one that came with the Mac Mini. Does seem like more than a coincidence though, especially because the monitor randomly flickers on occasion (it will black out for a 2-3 seconds, then come right back.)
  
• I'm using a an old MyBook external hard drive (connected via USB). It had a tendency to disappear in Windows due to a lack of power, so it could be related as well

.

Anyone experienced this issue before with a similar setup and found a resolution?

don't put it to sleep just set it like this.

the screen turns off but not the computer you burn about 2 to 4 watts an hour maybe 20 to 40 cents a month more juice. eventually you can replace the keyboard and the external hdd which may be the problem. I am almost certain the screen is not the issue. if this setting takes 20 seconds to wake let us know.

I actually think the display is the issue, I have to check when I get back home, but from what I've researched so far, certain settings on the HP monitor need to be disabled since they're designed with Windows in mind rather than Mac, and if not that it may need a new cable (either downgrade to a VGA connection or use a straight HDMI to DVI cable so now dongle is needed).
