Can closing the screen while the system is still hot damage the LCD?

I'm just being paranoid, but can the LCD get damaged if I close the screen after heavy usage? Right now I let my XPS2 cooldown for 15-20 mins before I even pack it up. My girlfriend gets all pissed having to wait for me and my laptop to cooldown, so is this a good thing to do to prolong the life and quality of the screen or totally unnecessary?

Thanks

I would be more worried about potential damage to the chip and what have you from having that heat that's not being dissipated, but likely (I have no scientific evidence to back this up) even that isn't an issue; once you turn them off they probably cool down quickly enough.

Seriously, the keyboard area on my system doesn't even get hot, how would this affect the screen?

This isn't an Alienware system, you need not worry.

I figured heat rises since the bottom of the laptop gets hot to the touch. I also thought the heat would get trapped if I closed it and put the system in my carrying case.. Maybe I am just being too paranoid

That's most likely the case

Keep that up and I'd be more worried about your girlfriend whacking it over your head. That'll do much more dammage.! Don't worry about it, Dell tests all that stuff, they even chuck coffee over them and stuff, I heard; to test before they're passed by "UL" labs.

It is a good idea to let it cool

Several Manufacturers recommend letting the system cool for 10-15 minutes before closing the lid. I've always found this to be a good idea. Why take chances with something that cost a couple grand or more? However, it the building caught on fire I would not hesitate to close the lid and grab the laptop and evacuate.

well, my laptop goes from my room to work, and from work to home EVERY day of the week. I NEVER wait for it to cool.. if i have to close up at 8, i pack up my laptop at 7:55. shove it in the bookbag.. and then i unpack it and turn it on at home around 8:10.

only changes i have seen in my LCD is that the light leakage has gotten BETTER. thats right, better.. i dont know how, but its not even noticable anymore..

so, with no research to back me up, only experiance.. i say, pack that bitch up and hit the road... i do it all the time and have had no side effects (yet... )... and ive done this about 60 times already....

More on LCD life

When one considers the lifetime of a laptop 60 times is insignificant. I have used laptops as my personal system for years; in addition I have seen what happens when the systems have not been well treated but if you have someone who buys them for you or you have an unlimited amount of disposable income then I guess it does not matter. This goes along with another pet peeves of mine and that is when I have to show someone something on my screen they inevitably put their finger on it. Oh well.

Your girlfriend is probably pissed because you're more concerned about the computer than her. Oh, wait. That wasn't your question.

I have great ninja skills with regards to finger-touchers.

I catch them mid-point and if it's not the parents, I tell them I'll snap their finger in two if they even think about placing their finger on my display.

I actually turned off my xps, closed the lid, waited for the xps lights on the cover to turn off then put it in my backpack - went away for 2 hours and when I came back the darn computer was ON...hot as hell, weird thing when I was shutting down it went on again with some error because of my xbox connection...

I runned some tests and it seems ok, been running for a week now no problems...so I wouldn't worry to much (maybe with what idiot me did but not just closing the lid..)

cheers

paranoid

just close it and go. Even if it did make a long term reliability difference, the system will be long out-dated before a problem arises. Pick your battles with your Girlfriend.... and this is one you shoudn't be making her mad over.

You're being paranoid. The laptop won't get hot enough or get hot rapidly enough to stress the glass in the LCD. Also, the heat the Laptop gives off through the keyboard is only due those nasty laws of physics. The Laptop's thermal design does not count on heat being able to escape through the keyboard. No need to wait for the Laptop to cool before closing the lid and packing it up. My Latitude D820 90% of the time sits at home powered on running at full clock speed with the lid closed in my docking station. It has not suffered any damage as a result. My Inspiron 8200 got the same treatment (sat at home powered on in the dock) and it too did not receive any damage.

Though I don't abuse my I9200 (it gets treated better than most pets), I've been abusing the crap out of laptops for years, and I've never had a problem with any screen getting too hot from closing the lid. Hell; if the Dell 5100 series doesn't have a history of LCD damage due to getting put away hot, than you've got nothing at all to worry about.

But if that old paranoia still haunts you, you can always load up I8KfanGUI and set up a profile to blast both fans on at full speed. Ten minutes before you're gonna finish using it, hit that profile in the taskbar, and it'll be nice and cool by the time you need to close that lid.

...And I hate it when people touch my damn screen, too. WTH do they gotta go & do that for?! Makes me wanna poke em in the eye!

I never wait till my laptop cools off either before I close the lid. Had the laptop for a little over a year now, and no problems.

I have also read/seen people who use thier laptops as a media center, where the laptop lid stays closed, yet it's still running. No problems from them. I have also closed my lid and connected my laptop to a desktop monitor and used it that way, again; no problems. I know others who have done the same.

Everynight my M1710 will sit on my desk, powered on, with the lid closed and it still shows no damage. I actually agree with an earlier comment, that if anything my screen is better. I to see less light leakage.......

Go figure

Hello. I'm new here.

It's advisable to allow the lapop to cool down bit before closing the screen and putting it back into the case. Laptop cases are good insulators and do no allow het to escape. The laptop remains hot for longer time.

Coming to think about laptop heat, these days we have lot of accessories to cool laptops - laptop desks, desks with cooling fans, laptop legs which raise the laptop by an inch from the table surface......

Using a laptop desk would also help us protect our laps from laptop heat.

I hate when people try to advertise on forums. Don't expect me to ever buy one of your products
