Re: 15 R2, stops charging under load and games crash
If the laptop is shipped with the adapter then it means its compatible with the laptop right their is no sense in buying a new more powerful adapter it's like wasting money after buying a car u need to buy a engine to drive it.
Except some of the Flextronic ones that were shipped with units were faulty or made improperly(not up to design specs). If the laptop is fairly new, that could be the issue.
