In this case, I wanted to have some information. I have Compaq presario cq40 portable not long ago. I was wondering if I was going to leave the Compaq presario battery CQ40 on the PC when I connect my hands at the same time ... but it was better to remove the battery when I am in AC ...? To avoid "give the battery."
What ??? A computation question on a mechanics page? in the end. If you can leave the battery in your laptop with the AC, there are no overload problems or anything like that, because they have electronic elements that protect it.
