I haven't had a chance to play with video card yet. I'm focussing more into the drives at the moment. Here are some issues I'm facing

It turns out that memory upgrade was causing that resume-from-sleep hang ups. Right now it seems that these laptops are very picky about every part put in it. The memory I tried are:
Not sure if the memory had errors, but the sleep-resume started working fine once I reverted back to the OEM modules and clearing the BIOS to factory settings.
I also ended up refreshing the OS to factory setting as I couldn't tell what was causing the resume hangs.
I will try another set of memory:
If that doesn't work, oh well. I have to live with 8G for now as the OEM 16G samsungs are about $500.
In retrospect, I probably should have ordered the non-SSD version. It would have been easier to swap out the drive with SSD.
I don't think there is any easy way to turn off the SSD cache and use the mSATA as a drive without changing the BIOS. If I make all these changes, Lenovo surely will cancel my warranty.

The resume from sleep failure was due to memory module (not SSD as I thought). Even after replacing the OEM memory modules, I had to reset the BIOS to factory settings for the resume from sleep to work correctly. I haven't found a 100% compatible memory module yet. I'm going to try the OEM 8gb version from samsung. I have checked online and it seems to be a major issue with W520s as well.

What is the mechanism of downloading the latest updates in Y480 ?
I mean any software similar to ThinkVantage System Update would be of great significance on Y series also.
Its like having a peace of mind.
