Hello hongyimofashi,   Text console interface is used when  using serial connection to console. If you are not using serial connection you can change the BIOS.   In the System BIOS go to > Serial Communication  >  select Serial Communication > set to  On without Console Redirection , save, exit and reboot.   [Please note I removed the attachment as it has service tag that is your private information]  
After setting the bios to default, it becomes like this in the picture, it turns out to be blue text on a white background。 Can't find any way to modify it, the bios version is 2.15 [Moderator removed attachment with private information]
