Dell XPS M1530 becomes completely unresponsive when entering sleep
Hi,
I have a Dell XPS M1530 which I installed Windows 7 Professional (SP1) x86 from MSDN.
Most times when the laptop is going to sleep from a power management sleep after x minutes, or closing the lid, this happens:
- The system appears to hang. There's no hard disk activity and nothing recorded in the event viewer around that time.
- The screen is black and doesn't wake up
- Capslock/numlock don't light up when toggled
And I have to hold the power button to turn the system off. When I turn it back on there's no evidence of a bugcheck or error in any of the system event logs.
What's the best way of starting to debug this issue and track down what's causing this?
Thanks!
