Can P150EM be used without a graphics card?

I'm just wondering if the P150EM can be used with integrated graphics when the discreet graphics card is removed.

 

i don't see why not. good question though... cue legit replies!

[pedant note on homophones: discreet ≠ discrete ]

 

It cant. Mythlogic found out that when trying to boot up with only the CPU's integrated GPU, the laptop freaks out and wont boot.
It just beeps and shuts down.

 

Ok, thanks. That's kind of dumb.

 

Yes it is...............

 

agreed. any idea about what causes the fail? this would have to be a mobo response, no? is there any link to mythologic's attempt?

 

Im afraid the search function might kill my office PC.

The problem lies within the BIOS firmware. Its made this way on purpose. If someone is a pro in modding it, then it might be done

 

so BIOS does fire for a moment, and then crash...? very interesting.

 

That's retarded, I thought an advantage of having an integrated GPU on your CPU is that if your graphics card blows up your laptop will still run!!

 

Probably just a dumb bios programmed to continue only if it finds a GPU whether or not it needs it. I suppose it might be possible to mod, don't know enough to do it myself.

 

Simply modding the BIOS isn't going to work; the iGPU needs to be connected to the display. The BIOS fires, doesn't detect a GPU at all, then shuts down.

 

Intel wants to integrate the whole motherboard on their processors.

Haswell will have this: "Fully integrated voltage regulator, thereby moving another component from the motherboard onto the CPU".

Memory controller was also moved to the CPU a few years back.

So...with more stuff being soldered on the CPU, we are getting effffed by having no choices to mod stuff on our machines.

 

But that isn't how the switchable graphics operate, right? The integrated graphics are connected to the display. The discreet graphics can be enabled when you want and then connect to the display through the integrated GPU.

 

it should theoretically be possible. after all, the alienware machines are very capable of booting and operating with only the iGPU (no dGPU present), as far as i know.

cheers

 

The way they worded it, something only needed to be physically present in the slot for it to work, and I guess that could include a dead GPU. Someone needs to test this.

 

hmmm, that would be quite neat indeed

 

This has been tested and busted several times.. one example would be the famous, as bob1man said, mythlogic test.

It simply wont work.. also here is another test and busted fact.. Review Eurocom Racer Gaming-Notebook (2720QM / HD 6970M) - Notebookcheck.net Reviews

I quote from that review @ notebookcheck

Same goes to the HD Graphics 4000 (Ivy Bridge)

 

huh? EM series support both Optimus and Enduro, so its not really the same for the HD 4000....

 

Oh my apologies I meant same for the HD Graphics 4000 as in neither worked..

Would be lovely with a hardswitch on the GPU.. Optimus is NOT optimal, really.

 

OK, the last 3 posts confused me... Whether or not you could use the iGPU on the HM models is beside the point as those were wired differently. The question here is whether it will work on the EM's if there is no GPU inserted, we already know it works with one.

EDIT: Oh I get what you were talking about.

 

How is the display connected anyway? I mean if it has to go through the mxm card, then you have to have one whichever gpu you are using, if the igpu has a direct connection to the display, then there's something else preventing the computer starting without the mxm.

 

my guess is that theres just some kinda additional code in the EC firmware making sure that theres a dGPU present. if that check comes back negative it wont let the machine boot properly.

 

The display is connected to the iGPU.
