Today I'm gonna buy a new laptop, I wanna make sure that everything is alright.
So is it true that when I buy my laptop I shouldn't turn it on until it's charged for 8 hours ?
Can't I turn it on before that ??
And is it true that I should remove my charger when my battery is full because when I don't it affects the battery's life ?
Thanks.
