how do you mean.... did the battery die, the GPU or what? and wasn't it covered by the warranty? and furthermore, did it get extremely hot, as the 4200m has a higher power consumption, I would think that it got quite hot during gaming?
I wouldn't recommend the z510, battery life is terrible, it died after 3 months of normal use.
i have that one with fullhd resolution. well, you can play latest games on med-high graphics. some games not really smooth, but setting lower resolution helps (1650*1020 or whatever).
i have set my eyes on this new lenovo z510 which has the i5-4200m mentoned above, windows 8, 1tb hdd & 8gb ssd, geforce gt 740m 2gb ded. graphicsa and 6gb ram. jus wanted to know if this computer's processor is capable of playing next-gen anfd latest games
