Taihsiang Ho, thank you for reporting this and helping make Ubuntu
better.
As per http://download.lenovo.com/express/ddfm.html an update to your BIOS is
available (2.25). If you update to this following
https://help.ubuntu.com/community/BiosUpdate does it change anything? If it
doesn't, could you please both specify what happened, and provide the output of
the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Thank you for your understanding.
