Re: My Laptop B490 not booting after bios update

hi sathish291

 

Welcome to the Forums.

 

Can you try the following:

1. Power down the machine, remove the AC adapter and battery.

2. Hold the power button for 30secs and reconnect the AC adapter only then turn the computer ON.

 

If the machine still doesn't power up normally and boot into WIndows then it's likely that something went wrong (could be a bad BIOS flash or an internal component might have gone defective during or after the BIOS update). In this case, you may need to contact lenovo on how to go about getting the unit serviced.
