i was wondering if using my lenovo y510p without my battery but having my ac charger cable plugged in can harm my hardware. i want to do this because i can only play games like fallout 4 for around 1-2 hours max without it getting very hot. and for my games to run well it is required that i have my ac charger plugged in. i have my laptop on a hard flat surface with a crappy laptop cooler under it. (planning on upgrading to a better one soon) my specs are: windows 10 64bit, 8gb ram (upgraded to 12gb), there is 8 i7 4th gen cores, nvidia geforce gt 755m, intel(R) HD Graphics 4600.
