Taihsiang Ho, as per http://www.dell.com/support/home/us/en/04/product-support/product/inspiron-17r-5737/drivers an update to your BIOS is available (A06). 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
