If you put a charger that it under powered, then the problem you are going to run into is you are going to stress out the charger too much and you'll burn it up as it will not be able to supply the computer with enough power. Using the higher wattage charger is NOT going to harm your computer. Which is it? More Less. Communities Get Support.
