Notebook hardware questions answered.

This situation should be that the laptop's battery is damaged.

There are 2 ways to fix it:

First, Kaihong, get the after-sales outlets of the early punch book, and let me help detect whether it is a repair or replacement battery.

Second, to get a place that specializes in selling notebooks, they are all connected with the maintenance of notebooks, the maintenance cost is cheaper than the after-sales outlets, but the quality of repair is not as good as the brand after-sales.

When using a notebook or other electronic product, use it correctly according to the instructions of the manual.

Premature damage to the battery caused by improper use. Products with batteries should be charged frequently when not in use to keep the battery charged to avoid damage.

Alarm sound, there is a problem inside, such as memory, etc.

1 long 3 short keyboard controller error. 4. Short system clock error.

Turned on a black screen? The screen doesn't show up? It is very likely that the liquid crystal is burned.

Maybe there is a problem with the system, go to after-sales.

First confirm that you can try it with headphones, if you can hear the sound, if not, reinstall the sound card driver yourself, if it doesn't work, you can only find the manufacturer's maintenance point for maintenance.

First confirm that you try it with headphones, remove the previous driver, and reinstall a new driver, if it doesn't work, you have to repair it.
