Answer:

The laptop either does not have a battery or the battery no longer holds any charge, thus shutting down instantly.

Explanation:

Most laptops will first try to their battery as a power source, and will then try to use their charger as a battery source. The charger icon is most likely showing up as fully charged because the laptop doesn't know there isn't a battery present, and assumes that it is fully charged.

Why does angular page look different after refresh.
alukav5142 [94]
Most of the web applications are written with SPA frameworks such as Angular, React, Vue.js, etc. The problem with these SPAs is that the single page is loaded in the browser once and then the framework will take care of all the routing among pages and gives the impression to the user that it is a multi-page application. When you refresh your page in the browser that single page called index.html is reloaded and you will lose the entire state of the application.
