That is, when the notebook computer 100 is turned off, the user can connect the external image processing device 102 to the notebook computer 100 or unplug it from the notebook computer 100; however, when the notebook computer 100 is turned on, the user can only Connect the external image processing device 102 to the notebook computer 100, and cannot be unplugged from the notebook computer 100
If the user directly unplugs the external image processing device 102 from the notebook computer 100 without shutting down the notebook computer 100, a system error will occur, resulting in a malfunction.
Obviously, such an operation method is likely to cause inconvenience in use, and there is a need for improvement

The invention relates to a method for safely dismounting external image processing device and a relevant computer system, in particular to a method for a computer system to safely dismount the external image processing device. The computer system works in a starting-up mode; the method comprises the following steps of: receiving a dismounting instruction, wherein the dismounting instruction is used for indicating the computer system to dismount the external image processing device; requesting a basic input and output system of the computer system to reply a management message corresponding to the dismounting instruction according to the dismounting instruction; and notifying an operating system of the computer system according to the management message to safely dismount the external image processing device. Aiming to the computer system with the external image processing device, the invention can realize a dismounting mode of hot drawing to improve the using convenience.
Description
technical field [0001] The present invention relates to a method for safely removing an external image processing device from a computer system and its related computer system, in particular to a method capable of realizing "hot-swapping" removal to improve the convenience of use and its related computer systems. Background technique [0002] Notebook computers have the characteristics of small size, light weight, and easy portability, which allow users to easily work outside the office and use various functions of the computer system without being restricted by bulky desktop computers. before the desktop. The convenience and portability of notebook computers allow users to have powerful computing power and word processing functions anytime and anywhere, and provide complete audio-visual multimedia functions. [0003] Although the notebook computer has the complete functions of the desktop computer and has excellent portability, the biggest disadvantage is the lack of scal...
