Model: Ideapad Gaming 3 (15ach6)
Describe the issue: I accidentally disabled the battery on my laptop in the BIOS, and now it will not turn on even if I plug it into AC.

What I tried already:

Reseating the battery & RTC battery
Pressing and holding the novo and power buttons

Issue started: immediately after disabling battery

New drivers/software: No, issue is BIOS related

#

Additional notes:

I tried to turn on the laptop plugged in to AC before re-seating the battery and RTC battery
I don't suspect any shorts while re-seating the batteries, since the battery is presumably disconnected
AC adapter is known to work

OK, I plugged everything back in after 5 minutes and it's still not powering on

#

Well... time to call lenovo

likely the battery BMS does not wake up for some reason...

I left it for awile and now it works in both AC and battery!
