Closed lid and heat distribution on 2090

I was wondering how bad it gets on the 2090 when the lid is closed. I hear it can overheat when closed for less than a minute? Will it overheat when the computer is doing nothing but running Word, and the lid is closed? And will it overheat when playing games, but using the zalman cooler?

 

Don't close it while its powered on, for any reason.

 

Wait what?

I researched a lot about this computer before making my purchase and never came across this bit of information. I plan on taking it to College and I want to have the OS running with the lid closed in my backpack taking it from class to my dorm room, or lunch. Every laptop I've had before this was able to do that. The Sager NP2090 can't?! This is pretty alarming news. Is there a way to put it to "sleep" and then close the lid?

I really don't want to have to shut it down each time I want to transport it, that would be such a pain.

 

Ok... someone smoking something?

All notebooks can be set to do whatever (sleep/standby, hibernate, shutdown) you want it to when the lid is closed.

All in the Power Options.

 

I am utterly confused then, why would it overheat if the lid is closed while the OS is running with applications? (I'm taking about applications like Word, AIM, etc NOT games)

 

Ninjazn, it used to be that there was no major problem to let the laptop running with the lid closed. However, with newer processors and GPUs it is not recommended to keep running software while the lid is closed, even if it is software that does not use the CPU or GPU all that much.

The computer is not right out going to melt but heat won't dissipate as well with the lid closed and that will shorten the life of the components. One thing that might be interesting to do is actually keep a log of strategic temperatures with lid open and then with lid closed while run-of-the-mill software remains running.

It is not a matter of NP2090 vs other laptops. That recommendation is good for just about any laptop out there.

 

Noob question:

dont have my laptop yet but wondering how to monitor cpu gpu temps and if its a program what reputable source to get it from

ty

 

its more of a case if your connected to an external monitor. Say your hooked up with a usb keyboard and mouse and use the computer, but on an external screen, if your doing that, its dangerous for the laptop. But if your just going to move around and wanna have something open while your moving should be fine. Basically its only dangerous if your using it ie:with external monitor where u can close the lid and work on the othe monitor.

 

RivaTuner, ATITools, nTuner are some of the choices available to monitor the GPU temp. Currently, the temps on the 2090 reads 57 degrees while under light use and tops off to 77 when gaming.

 

Everest reads the temps. I don't have a c2d but I'm thinking TAT also Motherboard Monitor (maybe) and Speedfan

 

I'll test the temps on mine when I get home, but all of my friends' computer all with C2D and decent graphics cards etc... close their lids while it's running and get very slightly warmer temps (slight enough that we only noticed the difference using a temp monitor. These are Sony, Asus, and HP laptops.

 

Same with Ninjazn, I'm going to be walking around a lot with my laptop, and just wanted to know if closing the lid while the laptop is still on for like 30 min or so would have any major effects on the laptop. I don't want to finish a class, and 30 min later when I'm in the library, find out that my computer turned off due to overheating. I mean, I guess I can keep it in hibernation, but is it that bad to keep it on while the lids closed?

 

read my post and u shall know its on page 1 somewhere

 

So if I have a few basic applications running and I put my computer on "sleep" or "hibernate" and then close the lid, I should be fine. Right?

I also thought that when you close the lid it automatically goes to sleep, most laptops do that.

 

Hibernate and Shut Down would be best, I think sleep keeps the computer still running, though at a reduced power. Hibernate just saves all your current data to the HDD then shuts off, and I think a computer shut off while on the move is the best, especially in the case of a HDD.

 

I think hibernate is the best way to go. but personally I always just turn it off when putting the laptop away.

 

The only time I like to shut down is when I'll be leaving it in my dorm room for a long time, or before I go to sleep. Otherwise I prefer having it on during trips to class, cafeteria, around the campus. I guess hibernation is my best option. Isn't there a way to set your computer to automatically hibernate when the lid is being closed? That way I could just close the lid before taking it to class and when I reach class I can just start it up again and it'll be a lot faster than starting it up when it's completely powered down.

 

What about leaving the lid closed while having the laptop on a laptop cooling pad or something?

 

that option is available in the "power saving" options

 

Control Panel>Mobile PC>Power Options>left hand side, it'll say "choose what closing the lid will do.

You get the option of what you want it to do:

 

Putting the computer to sleep is enough. When it is asleep, the only thing still alive is the RAM and the chips that control power modes. In that mode the heat generated is negligible.

 

Thanks for the picture GlueEater, that clears things up. Also, thanks Lemur, I'll be setting mine to go to sleep when I close the lid.

 

Ya same here, thx.

 

does hibernation cause any weird memory problems lets say.. if you forgot to save your word document, or if you were in the middle of watching a video (yes i know those can be avoided easily lol but hypothetically???) or is it simply as if you had never stopped working/watching?

 

Hibernation should not cause problems with your data. Even if you hibernate the computer right in the middle of doing something.

However, buggy drivers and buggy BIOSes do exist. In such cases, it is possible to experience data loss. I do not know of a testing suite to make sure your system is completely fine. If you've never used hibernation, I would advise to proceed with caution at first. Once you are relatively sure your system is not going to have problems with hibernation, you can be more bold.

Obviously, you should always keep backups of your data.
