Hp laptop battery indicator flashing orange?

I haven't used my laptop in a month. Today I put my laptop on the battery. The battery indicator was orange for a few seconds. After 10 minutes I tried to turn it on but it didn't work. I changed the battery but didn't work question is what is wrong with my laptop?

The battery is empty, connect the power source and wait, then you have to install the latest updates first and then you can start working.

Unfortunately, do not load I have been trying to load it for two hours but still not working
