Energy Management Driver problem

2013-04-21, 20:20 PM

Hello, I have an IdeaPad S10-3t, and I've upgraded it to Windows 7 Ultimate 64-bit. I have managed to load alternate drivers for all components except for Lenovo Energy Management, since Lenovo doesn't provide support for 64bit OSes on this tablet.


The problem is, Energy Management seems to be a 32-bit driver, and after I install it and reboot, the computer BSODs on startup, EVEN IN SAFE MODE,  and I have to do Startup Repair > System Restore and roll back to recover my system to a usable state. I've also noticed the Lenovo Active Protection system (the one that parks the hard drive in event of a free-fall) also causes BSODs when I install it...


I cannot use Energy Management or see the hotkey OSD because of this. Does anybody know where I can find 64 BIT drivers for the ACPI\VPC2004 power controller?

hi Azothyran,


Welcome to the Lenovo Forums


The Lenovo S10 series doesn't list any Windows 7 64bit drivers for the Lenovo Energy Management.. What you can try is to install the Lenovo Energy management for other models. Try these:


Lenovo Energy Management     Lenovo Energy Management

Windows 7 64bit / v4.4.0.8          Windows 7 64bit / v5.4.0.8

IN1EGC11WW6.exe                     IN1EGC15WW6.exe
7.66 MB                                           7.91 MB


Lenovo Energy Management      Lenovo Energy Management
Windows 7 64bit / v6.0.1.6           Windows 7 64bit / v7.0.3.9

IN8STW09WW5.exe                     cagt32ww.exe
13.4 MB                                           21.3MB


If one of the drivers above work, try to press Fn+ arrow up/down to increase/decrease the brightness



Hope this helps
