I have a brand new Studio XPS 13 which some times goes into sleep mode and wont cone out of it. The backlit keyboard comes on but the screen stays shut off.
I've had it for a week now and have tried updating drivers and all but sometimes..
The pity is that this is otherwise a fantastic bit of kit.

Stop do not pass go and get in touch with Support. You should not have issues with a brand new system. There is really no sense in you troubleshooting a brandy new system....Get the issue loged into the support system...
Before you contact Dell, make sure you are waking a Vista computer properly. You must press the power button briefly to wake a computer in Hybrid Sleep. You cannot wake it by just a press of a key. Press the power button to wake from Hybrid Sleep or Hibernation. Don't press the button too long or it will shut off.
