Question about Dell Alienware M15x Gaming Notebook
Last night, I shut down the computer. It was installing updates, so I left the room for about 3 hours. When I came back in it was on update 10 of 12. 40 minutes later it was still on update 10 of 12 and I was going to bed so I put it in sleep mode for the night and would finish in the morning. Well, this morning I pressed power to come out of sleep mode, and everything came on as usual except the screen. No flashing LEDs, btw. I tried rebooting and it didn't do anything. What can I do?
Looking at your last comment, it looks like you got it working??? Just an heads up, in the future, you might not want to put your laptop into sleep/standy mode while performing an update. If you lose power or have to do a hard shutdown you could corrupt the update and your PC might not boot back up.

Try this: Turn on your system while watching the display at an angle to see if there is any 'ghosting' to be seen.
If there is, then either the display back-light (CCFL) or the inverter that supplies the high voltage for it has failed.
The back-light lamps have a limited lifetime and the inverters are fairly frequent failures.
Unless you are very skilled with your hands and have a few tools, this isn't a good 1st project.

Check the BIOS for PC Health settings. It is possible that you have put a low value for "Critical Temperature", which makes the Laptop to turn off.

Testimonial: "Yes, this has been helpful. This could be an important clue. I wonder, however, why it would not turn off every 30 minutes throughout the day then. "
