Precision M6500 - screen shut off
I'm wondering if it overheated. I have an i7 version of the M6500
running Windows 7 64 bit. I came back from lunch and the machine was asleep. I hit the power button (it was flashing slowly) and the screen came on and I got back to work. After about a minute the screen went completely black. Fans were still running, hard drive light was flickering randomly, and the machine was acting normally. Just not the screen. The backlight was completely off, and I couldn't see the faint impression of the pixels changing colors. I've seen that before. I held down the power button and it restarted normally and I haven't had the problem since. Normally I put two erasers under the two rear feet to keep the machine about a quarter inch off the table's surface. That time I didn't. |

I think that a high heat shutdown is a hard shutdown, rather than
a sleep mode. The response to high but not excessively high heat is to slow down the processor. The screen not coming on might be a software screwup. I've seen that a few times and it didn't recur. -- On the internet, nobody knows you're a jerk. |

Ben It stays up and running 24/7 for me with no problem, for years at a time. Unusual things aren't as well debugged though, like automatic shutdowns of one kind or another. -- On the internet, nobody knows you're a jerk. |

Precision M6500 - screen shut off
I don't particularly like windows, incidentally.
I'd much prefer Linux, but that doesn't have all the drivers you need and all the updates to this or that fashionable multimedia format. So windows with Cygwin is my choice. So long as windows stays out of the way, it's fine with me. -- On the internet, nobody knows you're a jerk. |

The screen not coming on might be a software screwup. I've seen that a few times and it didn't recur. It turns out this is a well known issue. It happens when the chipset gets too hot. I installed a set of feet on the machine so its about a quarter inch off the surface in the front and maybe 5/8 of an inch in the back. I installed a 500GB Western Digital 7,200 rpm drive. I couldn't run more than five minutes without the screen blanking. I miss my Mac. I thought buying a Dell designed for higher end users would work, but nope. |
