The BIOS updates are available @
http://support.lenovo.com/en/downloads/ds037576.
The system is currently running on 1.09 which is oldest one, and 2.18 added a
hybrid graphic fix (see below and
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/gluj15uc.txt), but again
I do not have the required battery pack for updating the BIOS.
<2.18>
UEFI: 2.18 / ECP: 1.08
- (New) Added support for Hybrid Graphics on Windows 8.1 for NVIDIA graphics
models.
Note:
To support this, uninstall and re-install the NVIDIA graphics driver
after updating the UEFI BIOS from the version 1.18 or lower.
If someone in community can help comment or upload acpidump file, I can
do more analysis. If that's not the case, I would suggest to "won't fix"
this bug as it seems not affect any function.
