So I’ve made the mistake of buying a few of Lenovos laptops including one low range 17″ and two different gen gaming y520s and I hate to say it but that’s how long it took me to understand how absolutely shit they were, both of the y520 lacked any sort of driver/bios support, the other one of them for example had the CPU throttle curve made so terribly that the instant it became a little hot it dropped the clocks to 1.5Ghz effectively ruining the gaming experience.. there were no updates or anything from Lenovo despite many people having the same issue, someone had managed to make a really hacky way of fixing it.. BUT YOU SHOULDNT HAVE TO WRITE YOUR OWN THROTTLE CURVES INTO BIOS FOR A 1000€ LAPTOP.
The other two were just cheap plastic, bloatware and disappointing performance with boat loads of heat, I’ve since gotten smarter and changed to an Asus, trust me, I have never been happier. No longer is my lap on fire but I also get performance that i want withouth modding the god damn laptop.
