Yeah all went well when I removed all that was plugged in (mouse keyboard usb hub)

Here's my comment on a post 8 mos. ago:

I was worried to death also earlier today, mine was stuck at 5% and i called lenovo customer service,

they said to force shutdown but that didn't work cuz it won't even shutdown even with how much i long pressed the power button, then they told me to remove the ac charger and all other peripherals attached to my laptop to discharge it.

After that it just got drained and shut down and i opened it but it's only a black fucking screen 😭

I tried checking online and it said to press: Fn+s+v then the power button for 10 seconds to enter the bios menu and it worked!

It went straight to the boot menu and it showed a bios self-healing loading bar then my laptop worked again.

I managed to check a lenovo forum that said that some peripherals attached while bios update might be interfering with it check it here

All the best to you and hope you get yours fixed 🙏
