Lost BIOS in Acer Aspire 5750G

11 September 2012 - 10:41 PM

Hi, first of all here are my specs:

Acer Aspire 5750G
Intel Core i7 2630QM
4GB DDR3 RAM
nVidia GeForce GT 540M Optimus
Intel HD 3000 Integrated Graphics
640GB HDD

I was mucking around with the BIOS and managed to disable the nVidia card and allocate no VRAM to the Intel HD Graphics hence turning off both graphics cards... :(

So now my laptop does not show any screen, I have tried restoring the BIOS with a USB and FN + ESC but that did not work.
As I have been trying to re-install the BIOS I think I may now have a corrupt one.

I am now looking at shorting the CMOS Jumper but not sure how and if this will work?!
I have found diffrent threads online saying to do this with a screwdriver and others not to use one.

I'm wondering what other peoples view is on this, as currently I have no system!!!

Thank you

Trackpad gestures

I guess this is for mainly laptops, what gestures has everyone got working?

I got most working apart from side swipe/mission control swipe, want to get this working!

My system seems to just restart half way through booting up.
It doesn't show any Kernel Panic just restarts to chameleon?

any ideas?

How do I get GT 540M with mountain lion?

02 August 2012 - 08:29 PM

Hi, I have Nvidia Optimus with Intel HD Graphics 3000 + Nvidia GeForce GT 540M.
I have installed mountain lion fine, but only when I disable the switchable graphics therefore only having the Integrated card enabled.
When I try to boot with the Nvidia card enabled in the BIOS my laptop just stops on boot with this

"nspace-handler-set-snapshot-time:1343775763".

In Lion I wasn't able to get it enabled but I could at least boot with it enabled in the BIOS. Some people have said I need to make sure the Nvidia kexts have the right device ID but I don't know anything about that (and can't find anything related - only this

Thanks.

"nspace-handler-set-snapshot-time:1343775763"

Why is this?

thanks.
