Hi,
I setup Catalina on my Thinkpad x230 and everything was working great until I closed the lid and left the laptop for 2 days unplugged and completely drained the main battery. I now cannot get the system post. It turns on but never gets to the post screen. Tried pulling the CMOS battery to reset BIOS but still nothing. Tried draining capacitors by pressing/holding power a bunch of times but still nothing.
Is it possible bootloader or macOS wrote to BIOS when going into hibernate mode?
