[ktmmotocross]

Hello.
Have this gaming laptop that have ripped off both hinges. i cannot find both top and botoom case so i want to use it as "PC"

in bios is only video - LCD only or AUTOSELECT

but when i use autoselect without lcd it still not working on VGA or HDMI

is there a way to force it to use external video?

Re: Lenovo Ideapad Y570 - force to use external screen

maybe that is because my system not detect nvidia graphic. even with all lenovo drivers

so i think that gpu is bad or need reball or is toasted

im not surprized because when it get to me the fan was totally stuck by dust. i have never see that dusty laptop

IDK, acer 772g doesn't show from external VGA port till windows are completely turned on. Since Intel manages video switching from integrated to dedicated. Everything goes trough intel, if you don't have intel drivers it won't even show dedicated gpu as a device and won't let nvidia drivers to be installed.

Fast reading didnt see you mention code board. (sorry)

I think for LA-6884P boardview not present. from High res image seem near LDVS, for surely need trace that line.
