You risk heat damage to the LCD. Unless you have a Dell with complete care coverage I would strongly advise not allowing such situations to occur.

You can configure what the laptop does through your settings. Under Power management. For example, I have it do nothing when I close my lid that way I can display the image onto my 23 inch monitor. Have had the laptop running and lid closed now for MONTHS without any problems. Once the image is being displayed onto another source the Laptop Screen itself turns off.

Element,

Great job! you just scared jhayzhon into never closing his car door ever again while the car is running!

All things in moderation jhayzhon. Hopefully, Element means don't leave power management in charge of stand-by while the lid is shut for 5 hours straight!

The forum has discussed the unrelenting high fan speed after you bring your 'puter out of stand-by in some cases (not all, and not mine always). I forget the keystroke fix on that. If it does happen, I just restart and put the fan back into diagnostic mode. Trying to find the key combo in the forum - aw, crap, I'm not doing your work for you! You look!

Good luck!

This is all rather fascinating. I've also been doing this for the past month with my 9100. I did with my Latitude all the time and never had a problem but it was only a P3.

One time on my latitude I left it on and it got under the cover of my bed and stayed there all day while I was at work. When I got home I went to open it up, the LCD was nearly all black and blurry. I though I was F**KED. Turned it off for 20 minutes and booted it up and it was fine with no noticeable permanent damage.

I leave it on because while I go to work I leave it downloading little goodies for me to play with when I get home. The problem I have is a cat named Amber who thinks laptops are cat beds. (I think she thinks its the guaranteed way I will pay attention to her and not the laptop)

So the idear of leaving it open is not an attractive one for me as I've always had animals that always manage to do the darndest things.

I mean a simple download software wouldn't create too much effort for the CPU/GPU that it would be putting out too many BTU's that would fry my screen. At least I wouldn't think.

But this thread might be all I need to build a lil desktop server to do the downloading while I'm at work instead of abusing my 9100.

I love the 9100 because I have a LITTLE apartment and the idea of putting up a computer desk would take up twenty percent of my living space!

Thanks for the posts!

I run my system with the lid closed most of the time, as it is a desktop replacement. So, the system sits where my old desktop did, plugged into my external LCD monitor and other devices. It is well ventalated, and can even pull plenty of air from below it as it is suspended on a piece of metal with holes in it.

If this damages the system, then Dell will be replacing the affected parts. If they can't design a system properly to do what they say it can, then they can pay the cost of that mistake in warranty replacements.

So far after 3 weeks of ownership, I have not noticed an issue the few times it does actually use the internal screen.

I ran my 700m with the lid closed for almost a month straight with hardly any reboots. Though lately I've been running it with the lid open just to be on the safe side. I can't really tell if there is significant heat buildup with the lid closed. To be honest with you I'm more worried about spilling coffee on the keyboard than I am about long term heat damage, I may just run it closed from now on. It feels a little warm in spots but nothing like the 12" Powerbooks I've seen and Apple actually says you can run those with the lid closed.

how about turning laptop upside down? Heat naturally goes vertically up and will not buildup under display...

You could, but if you're running a 9100 or XPS, you'll just crush the screen. Some people have had problems with the trackstick scratching the screen, so I'd be leary of this.

I have been doing it for a long time and have had no problems. My screen does shut off when I close it, though. My laptop is only a i5100, also. I have been doing it since I got it and have had zero problems.

I might reconsider it if I were to own a 9100/xps, though.

Wow. That's a lot of help DF! Don't come on here and chastise someone for their advice, when you are not willing to do a little "work" to help them out yourself. I can't believe it. By the way, where is the reply to the COD message I left you. Haven't seen you in COD for awhile anyway. POSER!!!!!!!!

I'm pretty sure the fan reset is [Fn]-[z]

fan reset is func z, i don't see a huge problem with running the 9100 with the screen shut, most of the heat goes out the back.
