Hey guys, very strange problem (gotta say not yet thoroughly troubleshooted):

Lenovo Y50-70, Win10, 5 yrs old, original battery degraded to hold only 15-20 min, but when it would get too low I'd get a warning with enough time in advance to plug it in, or if I wouldn't it would gracefully hibernate.

Got a new battery, says original, has Lenovo logo, part number ###02 instead of ###01 inside my laptop. Installed, charged all the way to 100% from 84% (took really long too). Unplugged, had Chrome running with many tabs -- laptop hard-shutdown withing few minutes. Not hibernate, just powers off. Though ok, bad battery, but wanted another test. Unplugged, did not run any apps after start (other than what already starts up - settings for NVidia, Logitech, HP printer. Let it run for 30 min -- no problems. Started VirtualBox -> a Ubuntu VM I haven't started in a while, started updates. Everything was running normally for a long time while it was updating. Shut down VM, start Chrome, few min -- shuts down. Did another couple of tries -- shuts down when I start using Chrome (and not immediately).

Now, I haven't tested with other browsers or apps yet, but whats up with that -- no problem with VM running, but consistently shuts down with Chrome? Any tips on troubleshooting?

UPDATE 1: Another test -- Visual Studio + Edge -- worked fine for 30 minutes. Then decided to search for solution to this problem, clicked a youtube link (Edge) -- shuts down as soon as video starts playing. Suggestions say to install latest video drivers, but (a) latest NVidia drivers, latest Win10 updates (b) why only happens on a battery, and only on this new battery?

UPDATE 2: Shuts down on battery in "vga" mode -- when I start in special "text" mode when it lets me choose to into BIOS, or start recovery ... -- shuts down after a few seconds on this screen, or in BIOS if I'm quick to get there. On on cord. Latest BIOS version btw.
Also turned off "battery boost" option in NVidia Experience settings, didn't help.
Does not shuts down when watching videos default Win player (Movies & TV).

Connected old battery (thinking if I somehow damaged something during initial swap), and it works fine, the issue is not reproducible. Back to the new battery -- issues are back.

there is one, but Lenovo website doesn't seem to recognize battery numbers -- old and new numbers = "wrong format" , while format is the same for both batteries.
