Re: Did he melt his laptop?

In a panic I shot the last post off, with some logical assumptions.

The laptop was running from a power cable when this happened.

The battery was, and always is in the laptop, so it remains charged.

He returned to the office about 3 hours after he started the encoding and 
left.

Running from a power supply, what shut the computer down?

Did the computer overheat?

If the battery in the computer is always there and charged, why no power?

SO!!!!

What if the power supply just died?

Maybe it's a bad power supply?

He left the office with the laptop running from the power supply (cable and 
brick), the power supply dies, the laptop shifts to battery power, it runs 
off the battery until it dies.

No one is there to see a low batter warning, in which case we'd be able to 
say, 'Hey, it's plugged in and the battery is going to die, power supply 
must be dead!'

We come back and the laptop is completely dead.

No lights in the LCD panel, it's plugged in, the battery should be OK...

Maybe the meltdown idea is a bit off; a machine should shut down before that 
happens...

For now, we'll keep our fingers crossed for a faulty power supply.

Thanks for your response, we'll dig out the manual and look for some reset 
procedures if that happens to be the case.
