I just received my new/non refurbished Legion Y7000 from B&H yesterday.
I set it up and was charging it and noticed that yesterday it did not charge to past 90%.
Today I discharged until it turned off (may have just gone into emergency mode- as the screen went off, but when I plugged back in it went right to where I left off). Now it won't charge past 87%.
What is the deal? Anyone know how to change this or is it a problem with the laptop?

Welcome to the Community Forums.
Internally, the chips and firmware hold certain control for battery charging that prevents newer model from overcharging. Battery usually degrades easily on either full state of charge or fully drained. Keeping ideal charge of 20% to 80% should be healthy.
As per hardware manual (page 22)" Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life."
Similar software like power managers and Windows power options would influence its behavior so reading it may not be as accurate like we want it from what it actually holds phtsically.
Personally, as long as it can go up to solid white on the charging indicator (The battery has between 80% and 100% charge.) from off or solid amber (The battery has between 0% and 79% charge.) then it is all good.
If you really want to get the 100%, disable all power energy software or to set it in full performance. uninstall the battery driver from the device manager and turn it off. Have it plugged in for another hour without turning it back on. Take note that the firmware and battery chips may still automatically regulate it to buffer down so I cannot really guarantee it reaching more than the set 95%.
I hope this helps answer your query.
Update us how it goes.
