I decided to upgrade to Windows 7 Professional (64 bit) to maximize the performace of my Y510 for the coming semester of grad school.
Lenovo's Windows 7 information indicates that the Y510 is not currently supported in terms of 64 bit drivers, however, after searching the forums I found multiple rumors of Y510 users successfully installing various versions of Windows 7 64 bit and Vista 64 bit on the Y510. So, I decided to give it a go!
My previous system was running the standard Windows Vista (32 bit). To transition to the 64 bit operating system it is necessary to preform a clean install of Windows 7, back up your data and make sure C: drive is around 30 to 40GB (if you change partition sizes you will loose the functionality of the NOVO button, not that it's going to matter if you want Windows 7, but you could revert to Vista quickly by using it - See the U and Y forums regarding little C: and D: posted near the top of the forum for more details). You should also ensure that there are 64 bit drivers for your printer/scanner and other devices before switching over as some are not 64 bit compliant yet and will NOT work.
Below you will find the most minimalisitic instructions for getting your Y510 maxed out for Windows 7 64 bit.
To begin it is recommended that you preform a clean install of Windows 7. Here is a step by step guide (linked below) just incase you haven't done it in the past. Read the guide and make a few notes or get the help of a friend who is familiar with the process. It's pretty simple really.
Once windows 7 is finished installing you need to do the following to reinstall missing drivers.
Lenovo Y510 Drivers and Software Download Page: http://consumersupport.lenovo.com/en/DriversDownlo
Note: I followed the order of the drivers chart as chipset, storage management, video, audio, ect drivers should be installed in this order, be sure to restart the computer between the installation of the first few drivers as they are part of the system core)
1) Install the Intel Chipset (Windows Vista 32bit) from the Lenovo support page above. (Yes, I realize it says 32 bit, don't worry it is 64 bit compliant apparently)
2) Download and Install the Intel(R) Matrix Storage Manager: http://downloadcenter.intel.com/Detail_Desc.aspx?a
3) Download and Install the Realtek Audio Drivers: http://www.realtek.com.tw/downloads/downloadsView.
Note: The audio panel where you can manipulate sounds, equalizer, speaker setup,ect is built into the driver only package linked above.
4) Download and Install Energy Management and ACPI Drivers(thanks KillFire):
Note: The Lenovo Y730 shipped with Vista 64 and therefore has a 64 bit compliant Energy Management system (thanks Skripatch and KillFire!). The Y730's Energy Management Drivers seem to solve the Energy
Management System and missing APCI device issue for BOTH Windows Vista 64 bit and Windows 7 64-bit editions.
5) Download and Install Synaptics Pointing Device: http://drivers.synaptics.com/Synaptics_v14_0_3_C_X
At this point the following two devices appear missing in the 'device manager' section of the control panel:
Base System Device: PCI bus 8, device 3, function 3
To fix these issues insert the drivers disk that came with the y510 or download them from the lenovo support page:
Base System Device: PCI bus 8, device 3, function 3 = Rioch Memory Stick Host Controller
Base System Device: PCI bus 8, device 3, function 2 = Rioch SD/MMC Host Controller

I got the following error message when attempting to install any of the "Lenovo Software Package V5.23", for example, power2go burning software.
"This software can only be installed on a LEGEND Dragon system"
I'm guessing this is a side effect of changing from 32 bit to 64 bit?
What exactly is a "LEGEND Dragon system" anyway?

The system seemed to be running fine for the first couple of days, however, after a few updates from MS the system is now randomly crashing...
It freezes completely and the only option is to soft off the computer... Any ideas?

System was upgraded to 64 bit Windows 7 Pro.
Windows has never been 'specific' while crashing...
I checked Reliability Monitor and it shows system stability falling off over the past 4-5 days...

Other than that it just says "Windows was not shut down properly" and offers no further details as to why or what caused the failure.
Could the ACPI be screwed up still? I had loaded the Y730 power management software initially and it seemed to be better than the Y510's for 64 bit editions of vista and 7. I have also tried the fix above from KillFire and am still crashing for some reason...
Can someone who has successfully installed Windows 7 64 bit or Vista 64 bit on the Y510 provide some insight/instructions - apparently I have missed something serious!
Lenovo needs to step on getting 32 bit and 64 bit drivers out for our systems!

probably acpi driver causes this. restore your system to the day system worked fine.

one more, a little fix for intel is here
note: to run the utility on vista* and windows 7*, right-click on CHIPUTIL.EXE and click "run as administrator".

windows explorer constantly crashes.. if i right click anywhere on the desktop after a while of surfing the web it does this.. so my guess is one of the drivers need to be updated correct?
thanks guys for your help on this.. much appreciated!!

Yep, same issue bluesocks... was fine for the first few days and then the explorer started taking a dump for un-explained reasons and the computer entirely freezes/restarts.
Has anyone tested the suggestion above yet using a Y510?
If any one from Lenovo is out there:
Yes, there is demand for idea systems to be updated to Windows 7 64 bit and the appropriate driver sets would be greatly appreciated for the remaining systems by your customer base.
