1. If the notebook is self-locking or locked. If it is self-locking, it can basically be judged that there is a height difference when the rotating shaft is assembled;
2. If it is locked, it may be that the lock is not in place or the related plastic sleeve is damaged;
You can check whether something is stuck without turning off the LCD. Check the lock again for signs of failure.
4. Because the general notebook computer is foldable, if the display screen is often turned over for a long time, the rotating shaft will be too loose and the cover will be lax.
5. This kind of situation is common in notebooks, and the only solution is to go to a computer repair shop to replace the rotating shaft.
1. There is something wrong with the opening and closing shaft. If it affects the use, please go to customer service as soon as possible.
2. This is the screen axis. The screen axis of the notebook will naturally become more and more loose after being used for a long time. Just find a maintenance station and change a pair of screen shafts.
The screen shaft has damping compensation (elastic compensation), and the screws are generally adjusted when they leave the factory.
The average user may not be able to adjust.
Of course, different notebooks use different screen axis technologies.
It is recommended to consult the official customer service of notebook.
If you can't adjust the screws, you can also change the screen shaft to achieve better opening and closing effect.
It depends on the loose part. Generally, the cover is loose because the screw is loose, which can be tightened with a matching screwdriver. But be careful not to tighten it too tightly, or the screw will slip or break.
Another situation is that the hinge is loose, and the hinge will not be loose easily. Most screws for fixing hinges are loose, just tighten them. If the hinge is determined to be loose, it can only be replaced or used.
