Taihsiang Ho, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product- support/product/latitude-e7240-ultrabook/drivers/advanced an update to your computer's buggy and outdated BIOS is available (A17).

Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.
