Problems solved by technology
[0005] 1. When the operating system suffers serious suspended animation and no response, it cannot be called out, and the computer can only be reused by restarting the computer, which will lead to loss of various important data and waste of time and energy
[0006] 2. Unable to automatically distinguish and display the current problem bottleneck when the software calls out
[0007] 3. Unable to deal with the current problem bottleneck
[0008] 4. The function is not complete, and some operations cannot be performed on related programs, such as suspending or restricting, etc.

Embodiment Construction
[0033] The keyboard filter proposed by the present invention and the method for waking up an unresponsive operating system will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] Such as figure 1 As shown, the present invention provides a keyboard filter 20, comprising:
[0035] The acquisition module 201 is used to intercept all key information of the keyboard 1 immediately after the operating system has no response, until the key is an agreed activation shortcut key;
[0036] The scheduling module 202 is used to take over the scheduling of all current active threads and resources to restore the normal scheduling of the operating system and return to the desktop before the operating system has no response;
[0037] The processing module 203 is configured to receive the agreed activation shortcut key intercepted by the collection module 201, start the scheduling module 202, activate the interface program 30 of...

The invention provides a keyboard filter and a method for waking up a no-response operation system. The method comprises the following steps: collecting activated shortcut keys appointed by pressing a keyboard through a collection module and responding to the activated shortcut keys when an operation system has no response or even severe false dead lock occurs; making a scheduling module takeoverresource scheduling after a processing module responds to the activated shortcut keys; and activating the interface program of the operation system to create a virtual desktop, so that a user can clearly see the current resource use condition and conduct corresponding operations so as to recover the normal operation of a computer. Furthermore, the virtual desktop can display the problem causing no response of the operation system, the operations of suspension, recovery, limited use and ending of all active threads and resources and the priority adjustment operation, and can give an operation prompt to assist the user to rapidly solve the problem when the operation system of the computer has no response due to false dead lock so as to reuse the computer.
Description
technical field [0001] The invention relates to the application field of computer operating systems, in particular to a keyboard filter and method for waking up an operating system when the operating system stops responding. Background technique [0002] When the user is using a personal computer, the operating system may run abnormally due to the insufficient robustness of the application program or some inappropriate operations performed by the user. Typical phenomena include the unresponsiveness of the operating system, the suspended animation of the desktop program, and the inability of the user to Interact with the computer, etc. [0003] Under prior art, the method for solving operating system suspended animation generally has two kinds, and a kind of method is by means of the task manager that operating system carries (hot key is Ctrl+Alt+Del or Ctrl+Shift+Esc), another kind The method is to call out the task manager in the form of a third-party hotkey. [0004] How...
