To fix the screen tearing, white lines, artifacts appearing on the screen after monitor sleep wakes, we need to edit the dsdt on our Lenovo G770 Sandy Bridge HD3000 Laptop.

can you put up the dsdtfixartifacts.rtf file up to make it easy to copy and paste
Hello Stan,
It’s on the download page in the final Extra folder.
You have showed great perseverance behind the blog. It’s been enriched since the beginning. I love to share to with my friends. Carry on.
Hey DogMonkey…
Your instructions work very well for my acer s3 under SL 10.6.8. I have 98% working machine. Only wifi does not work but i addressed it with a usb wifi dongle
However, for Lion 10.7.2 your dsdt.aml boots fine but shows 4 screens on my laptop..haha
I did not use the DP4 kexts… just normal 10.7.2 with chimera 1.4.x. QE/CI is achieved by this bootloader but i get slight screen tearing (without your extra fix or dsdt.aml) ….can you help???
thanks
