Hi,
We've been having this problem on and off for a few weeks now. The tower turns on but is very quiet and the monitor tells us that is is in D-Sub power save mode and will not come on. We tried putting the computer in safe mode by pushing the power button and tapping F8 at the same time. We have also tried shutting everything down and unplugging. No luck.

I have the same problem when powering down the system. I found that if you turn off the power on the monitor before the sysem shuts down it usually wont go into the power save mode. Just dont turn on the monitor when you power up until the system reboots.

Hm. Tried that but no luck. Any other suggestions?

We tried putting the computer in safe mode by pushing the power button and tapping F8 at the same time. That is not the way to do that. You tap f8 repeatedly when the computer starts to boot. Or is the way you describe trying to boot into safe mode just a last ditch effort.

I googled and this poster says he solved the problem with his Dell.. This seems to be a problem with Dell.

.
Go into Power options. Look at and customize your basic power plan (or whichever plan you are currently using). In there there is an option to set sleep mode to never come on. Do that.
You then have to go into advanced power options. I think under the sleep section there is an option to allow "hybrid sleep" mode. That is probably still set to yes or on. Turn that off or set it to no (can't remember which

I've read that but how can you do that if you can't see the screen?

Sorry dummy me wasn't thinking.

Well since no one else has come forward to help you here is another thing you can try.
Shut the system down, HARD SHUT DOWN. Then Open the cabinet up amd remove the video card and scrub the gold contacts with a pencil eraser. Then reseat the video card.

Again this worked for a poster I found Googling. Good luck

It sounds like the computer isn't booting. That's not a monitor or video problem.

I am not going to argue with a Geek but this is part of what the poster said.

Just because the computer is getting power, doesn't mean it's booting. I read all the posts.

Yes and I just realized how did the poster see that message if he has no screen.

Dell has decided it's a power source problem and is sending us a new part. We'll see if that works.
