Thank you for the guide. For the slow connection maybe you can try Opera browser's VPN feature to reach it. It's worth give it a shot.
I know the guide by Rehabman for disabling Nvidia but it's too complicated. It has a lot of patches and it's not clear which patches should I use for my TP500L instance. There are over 20 patches in the guide. Which patches to which SSDTs are the question.
You have 9 patches for DSDT on your guide, however, following posts complained that they lost ethernet, sata, audio, touchpad etc. Should we really need to apply all those 9 patches?
