Hello Kido!
About your first problem;
My ques is that have you format ur pc? If not then repair it, may be some files are missing!

And about second,
There is no different types of battery, but are u sure that u have installed it properly?
It will better to check it and change ur BIOS settings to default value and then set it as u wish!

Wish this will help u to solve it!!!
Thankz!
Bye!
