Default 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.

Is anything reliable with Windows?

It's 99.99% reliable. It's just that we all keep stumbling across the 0.01% regularly... 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.

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.

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.
