Hi i don’t know if I am on the right place, but i want to buy an notebook, but this notebook that i want to buy is on second hand, but i never ever bought an notebook, and I don’t know what specs to look in an second hand notebook, the guy who is selling… is selling an “Acer aspire 5920G” seems to be a great notebook for what i read… but… the guy says it has replace the graphics card…. The reason for the replacing i don’t know why… but what is my doubt… for replacing the graphic card, what means the notebook can have other problem.. Or i don’t know something bad, or is normal that happen? In advance thanks for any help, and if you guys think that i must take a look to order specs please tell which specs
