I’ve had this laptop for about 9months now. It does overheat, so keep an eye even if you have it on sleep mode. You will hear the fan go off and try to cool it down, if that happens..just turn the laptop off until fully cooled. My laptop pretty much stays at 80% charged at full charge. The laptop is refurbished though, so that part is understandable. I did see another comment with a video showing how the laptop won’t turn on/the screen even when it’s been plugged in etc etc. I can also relate to that, I also had that problem. I eventually figured out a little hack I suppose, just try turning it on by pushing down the button for over 15seconds while plugged in. If that doesn’t work..let it charge for a bit and do it again, and or unplug it and press the power button again for 15seconds and it should work. Other than those problems, I am satisfied still. If you use press down on “fn” on your keyboard/lower left side…then press “f5” at the same time, it turns on your keyboard backlighting. If you press “fn” with any of the “f” up top it turns up ur volume/screen brightness/snap shots/etc etc etc
