I purchased a laptop that had a battery option available.

The standard option is a 65 watt battery and the laptop shipped with a 65 watt power adapter.

The next option is a 90 watt battery and the laptop shipped with a 90 watt power adapter.

I purchased the 90 watt battery with a 90 watt power adapter.

One day when I booted my laptop I started getting a post message that says a 65 watt power supply cannot be identified and provides several post options one of which has to be selected for the laptop to boot.

I assume the BIOS is designed to work with a 65 watt power supply and if it does not see 65 watts where it is more or less wattage the BIOS will take issue with it?

When I looked in the BIOS the information is blank where the power supply information goes.

Any information regarding this would be appreciated.
