After following, you can keep track of his dynamic information in a timely manner
First try to force restart and turn off the fast boot, enter the BIOS to disable FastBoot to ensure normal hardware initialization; 2. Unplug all external devices, keep only the keyboard and mouse, and troubleshoot startup stutter caused by faulty peripherals; 3. Re-plug and unplug the memory stick and clean the slots, check whether the graphics card and power cord are connected firmly, and test a single memory one by one if necessary; 4. Disconnect the data cable of the main hard disk or SSD to determine whether the self-test cannot be passed due to storage device failure; 5. Clear CMOS to reset the BIOS settings, and restore the default configuration by jumper or remove the battery discharge; 6. Pay attention to whether there are any alarm sounds or signs of overheating during booting, and use the motherboard manual to interpret beepcode to judge hardware failure; 7. Use a bootable USB disk to try to boot from the external system

First check whether the touchpad is disabled, try to enable it using function keys (such as Fn F7) or physical switch, and confirm that the touchpad switch is on in the settings; 2. Update or reinstall the touchpad driver, find the corresponding device through the device manager and update or uninstall it and restart it to automatically reinstall; 3. If the settings show "Your PC does not have a touchpad", you need to visit the official website of the notebook manufacturer to download and install the correct touchpad driver; 4. Run the built-in hardware and device troubleshooting tools of Windows to automatically detect and fix problems; 5. Check the BIOS/UEFI settings to ensure that the internal touchpad or pointer device is not disabled; 6. Make sure that the Windows system has been updated to the latest version to obtain the latest hardware compatibility support, and finally

In Java, this keyword is used to refer to the current object instance, and its core uses include: 1) distinguishing instance variables and parameters with the same name; 2) calling other constructors in the constructor to implement the constructor chain; 3) passing the current object as a parameter; 4) returning the current object from the method to implement the method chain. For example, use this.name=name in the constructor to explicitly assign instance variables; call other constructors through this() to avoid code duplication; use someMethod(this) to pass the current object into other methods; or use returnthis to implement continuous calls to improve code readability and simplicity.

Symbol search is used to quickly navigate code elements in VSCode. The answer is to achieve efficient search through shortcut keys and language support. Specifically: 1. Use Ctrl Shift O (Windows/Linux) or Cmd Shift O (Mac) to open the symbol search of the current file. You can enter the symbol name or use: delimited nested symbols; 2. Press the @ key to quickly trigger symbol search in the file; 3. Use Ctrl T to search for symbols in all files within the workspace, and the results will contain symbol names and files to which they belong; 4. Functions depend on language servers (such as TypeScript or Pylance), and the corresponding language extensions need to be installed to ensure that the file is saved and the syntax is correct, and the language server is running normally;

The answer is: Use the std::string constructor to convert the char array to std::string. If the array contains the intermediate '\0', the length must be specified. 1. For C-style strings ending with '\0', use std::stringstr(charArray); to complete the conversion; 2. If the char array contains the middle '\0' but needs to convert the first N characters, use std::stringstr(charArray,length); to clearly specify the length; 3. When processing a fixed-size array, make sure it ends with '\0' and then convert it; 4. Use str.assign(charArray,charArray strl

Slow web page loading does not necessarily mean a network speed problem. It may be caused by router interference, excessive devices grabbing bandwidth, abnormal DNS resolution or insufficient device performance. First, check the location of the router, stay away from interference sources such as metal and microwave ovens, use the 5GHz frequency band and replace the idle channel; second, check the number of connected devices, turn off automatic background updates, and enable QoS to ensure the current device first; then try to replace the public DNS, clean the browser cache or change the browser test; finally, check whether the Guangmao and the router are aging, and replace the new device or restart the router if necessary.

In Oracle, PIVOT operation can be used to convert rows into columns. The answer is: yes, it is supported from the 11g version; its basic syntax is SELECTFROM (source query) PIVOT (aggregation function (column) FOR to be converted into column IN (value 1, value 2,...)); for example, a quarterly perspective of sales table, using SUM (amount) FOR quarter IN ('Q1'ASQ1,'Q2'ASQ2) can obtain employee quarterly sales; when using PIVOT, you need to note: the aggregate function must be used, the value in the IN clause must be known in advance, the string value must be case sensitive, and column alias can be specified by AS; multiple aggregations such as SUM (amount)ASsum_amt,

std::barrier is a thread synchronization mechanism introduced by C 20, which is used to allow multiple threads to merge and continue execution at a specified point. 1. Specify the number of participating threads when creating the std::barrier object. For example, std::barrierbarrier(3) means that 3 threads need to be synchronized; 2. Each thread calls barr.arrive_and_wait() and will block until all threads reach this point and release them together; 3. Optionally, the completion function can be passed during construction, such as []{std::cout

To create pre-selected options in the HTML drop-down menu, you need to add a selected attribute in the target tag; for example, Banana will make "Banana" selected by default when the page is loaded; 1. Only one option should contain a selected attribute (unless it is a multiple-select drop-down box); 2. Selected is a Boolean attribute, which can be effective as long as it exists, without assignment; 3. If there is no selected attribute, the browser usually selects the first option by default; 4. It can be dynamically pre-selected based on user data in combination with JavaScript (such as setting value) or server language; 5. This method is simple and natively supported, suitable for static and dynamic scenarios.

tmp_path is a temporary directory fixture provided by pytest for file operation tests. 1. It is automatically created before each test and cleaned automatically after test; 2. It supports pathlib.Path operation, which can safely create files and directories; 3. It can be used to write and read files, verify directory structure, and use with open; 4. It is suitable for scenarios such as test configuration generation, log writing; 5. It is recommended to replace the old version of tmpdir, and the temporary content is automatically cleared after running to ensure that the test is isolated and pollution-free, and is the preferred tool for file-related testing.

static member functions belong to classes rather than objects and can be called directly through the class name. 1. Only static member variables and other static member functions can be accessed; 2. Commonly used in tool functions, counters, singleton patterns, etc.; 3. Static member variables must be defined separately outside the class; in the example, the number of objects is counted and class information is output through the static function, which fully demonstrates its usage and characteristics.
