Y400 Windows 7 64bit Downgrade guide needed please

2013-01-23, 18:37 PM

Ordered two of these Y400s for work and received last day of December. Had our IT shop downgrade them to Win7 Pro per corporate standards. However, they had a number of issues and I had to correct most of them. I will be doing a full reinstall on one of them and I can't quite find a good how-to guide for the Y400 model with the 16G mSSD drive option.  I need to get the setup of the 16G mSSD correct so that it is used as fast caching (not working in both laptops currently) - I see similar guides on other Lenovo laptops but most are also for a larger mSSD which can hold the full OS.  Also, I've got most device drivers working but for one (shown in Device Manager properties as "APCI\VPC2004" Unknown device.  It may be a need for Lenovo's Power Management software, but not sure.  If anyone has a complete list of Win7 64bit drivers for the Y400 that would be much appreciated.  Thanks!
