Just click this button with the mouse and the unlocking will be successful.

Method 2: You can set BISO by

If the laptop keyboard is locked, you can restart the laptop. During the startup process of the laptop, enter the "F2" key to see if it can enter the BIOS safe mode. If you cannot enter BISO safe mode, this may be because the data connection cable of the laptop keyboard has become loose and needs to be sent to a maintenance center for repair. If you can enter BISO safe mode, you can then observe why the system is locked. Then press fn + scrlk or shift + scrlk (that is, one of the Fn or Shift or Ctrl keys + Numlk key.) to try.

Part 2: Irregular keyboard key failure

1. Take apart the keyboard. Note that when opening the keyboard, the button surface (that is, the side we operate) must be downwards and the circuit board must be upwards, otherwise the conductive plastic on each button will fall off one after another, causing trouble for your repair.

2. Open the circuit board. The circuit board is usually made of soft plastic film with button wiring engraved on it. Use alcohol cotton with a concentration of more than 97% (75% medical alcohol cotton is also acceptable, because I have used it before. But it is best to use high-concentration alcohol cotton) to gently scrub the circuit board twice. It is necessary to take care of the circuit of the key failure part several times.

3. Check the conductive plastic of the failed part of the button. If there is a lot of dirt on it, use alcohol to scrub it. If the conductive plastic is damaged, the author recommends that you replace the conductive plastic on the infrequently used keys with the damaged part. Although this "removing one wall to make up for the other" approach will not allow the keyboard to exert all its functions, in the end it will At least it can extend the life of commonly used keys.

4. To remove dirt from the corners of the keyboard, you can use a brush, a small brush, etc., but be careful to be gentle.

5. Check whether the soldering module is soldered or desoldered. If you can use a soldering iron, you can perform repair soldering work. Of course, this step is only suitable for friends who can use a soldering iron. For those who don’t know how to use a soldering iron, please skip this step.

6. Install the keyboard. One thing to note here is that you must wait for the alcohol to evaporate before proceeding.
