24" iMac light inside even when off

Cheers Fall,

Thanks for the good luck wishes. Yes, I must have just been unlucky. In saying that, the screen on my iMac was perfect too. Not one dead pixel. I see, from one of your other threads that you have a few dead pixels. I hated sending my iMac back. Partly because I was originally worried about dead pixels and this one was perfect. Wait till this replacement arrives. I bet there are loads of them :(

Aw bummer, to bad you can't request that same screen ;) I'll pray that you at least get a perfect one!
 
i dont know if it has been said already but the LED inside a computer that normally stay on it WOL. Wake On LAN so a tech can turn the computer on remotely to install updates and maintenance .
 
Bingo!

Thanks BabyJen,

That could be just what that LED is. Hey Maverick, try this out and see if the little LED goes off.

Click on System Preferences, then Energy Saver. Now de-select the "Wake for Ethernet Administrator Access" and see if that switches off the LED.

You most likely will not need Wake-On-LAN, so there's not much point in having it enabled.

Try that out and let us know how you get on.

The problem is that even if you turn the machine off there is still a dull light you can always see, which is kinda annoying if you have the iMac in the room where you sleep, as I do. What I do now is place a book in front of the light so that it doesn't bother me while I'm trying to sleep. Do you really think that having to do that is not at least a slight annoyance and problem? It's not enough to send the iMac back, and I do love the machine, but it IS annoying, even if only a little.

Before the 24" I owned both the last revision of the 20" G5 iMacs and the 20" Core Duo iMac. Neither had a part of the plastic that you could see through. So basically, in a perfect world I would prefer if the latest 24" iMac didn't have a part of the plastic you could see through.

I had to laugh when you mentioned having to sleep with with the light from a single, small LED. Evidently you've never seen the lights that are built into most of the high end power supplies and MSI motherboard chipset fans these days. Even with the case completely sealed, my Windoze workstation looks like a scene from Starwars is being shot inside when it's running and has two LEDs that glow when the machine is shut down.

Black electrical tape works fine to cover them up.

I tried turning off "Wake for Ethernet Administrator Access," and that light still is there.

hmmmm.....

I'm wondering what that heatsink in the picture is hiding. I don't think it could be the CPU or GPU, could it?

I'd like to see complete disassembly pics with labels included of all the major components. :p

ESPECIALLY the MXM card, where is it and how hard is it to get to and remove? I'm hoping it's easy, so then maybe there'll be aftermarket upgrades sometime in the near future! :D

My bet is that it isn't the GPU.

iMac Comparison

The CPU and GPU share the same heatsink.

Tried it and, unfortunately, it doesn't make a difference. And I actually do use the wake on lan functionality quite a lot so I do need it on.

I tried to take a picture with a long exposure to show what it looked like, but the camera couldn't even pick it up. I've decided I don't really care and will just live with it.

Thanks for your help though, I appreciate your suggestions.

you would not be able to turn it off there, as far as im aware it can only be turned of via the bios, but in some cases it stays on, there is another feature i think its to do with WOL. There is a way for a admin to send a wake command to the power-supply as well. I did this all the time on my last job, you send a wake command to 100 PC's and they all boot up for the staff arriving 30 mins later. Similar to WOL but for a different purpose. All the light is telling you is that the computer can be remotely woken.
 
"Opaque" means light cannot pass through the material, not that it's translucent. Opaque is the opposite of transparent, translucent is something in-between (like in this case).
 
I don't have an Intel iMac (yet!) but have 2 iMac G5s and those LEDs are just for diagnostic purposes. There's info about them here. The first one should always be on if the iMac is plugged in... shame you see it through the casing though.

I just noticed while my iMac was asleep in a completey dark room that there is a very subtle light I can see in the center of the chin, about 1 inch right and one inch down from the Apple logo. I do not mean the sleep light which pulses away at the far right, I'm talking about another very faint light just beside the Apple logo.

If the room is completely dark I can see THROUGH the white plastic and see a metal grill patern behind it. If i turn the iMac completely off the light is still there. The only way to get the light off is to switch the plug off at the wall.

Does anyone else with a 24" iMac see the same thing. It's very very subtle so you'll have to be in a competely dark room to check.

I think your imac is haunted.
 
My 20" C2D, also has a small LED green light at the bottom where the mesh is, don't know why, it can't be networking as it's wireless, even when the computer is shutdown it still remains on
 
Yeah I Got It Tooooo...booooooo

yep, ive got a 24inch imac and havnt noticed it, you can see a small light source through the mesh next to the logo, i never noticed it until i read the FORUM, all i did was cover the area where the logo is on the right with my 2 hands allowing no light to come through and look closely, you can see it even if my light it on. it is very minimal and does not concern me, MSN me if u got any issues or what ever, hotommy@hotmail... :eek: :apple: :apple: :apple: :apple: :apple: :apple: :apple: :apple:
