Hello,
I have a Asus A42-M70 Laptop with Windows 7.
I have my original battery has dropped there some time and lack of money to replace it right away, I waited. Lately I wanted to change the battery but my charger dropped in turn.
So I had to buy a new battery and a new charger at en.ofweek.com/Product/Original-Laptop-Battery-for-Asus-A42-M70--prod-14421-111649.html I found but adaptable.
I have just received the battery is recognized as the charger but the problem I have is that the battery does not want to put in charge. I just checked the characteristics of the charger and the battery between old and new and the only difference is in the charger or there is a difference of less than 0.5 A for the new charger.
-Is someone could tell me and help me solve my problem?
