How to clear the CMOS on MSI GE76 Raider

Feb 24, 2022
Months ago I tweaked the crap out of this laptop's bios. It took me many trials to get it just right, having to reset the BIOS many times. One of those tweaks was disabling the onboard graphics (I don't care about the battery life). Anyway, somewhere along the way, it got reactivated by itself. That is not cool!

Now tweaking it I chose the wrong display IGFX and it won't display at post. So I'm back at square one needing to reset the BIOS just like I did 15 times before. Though I clearly remember doing this without opening the laptop, I forgot the key sequence. Could someone refresh my memory please? For some reason I can't find this simple task anywhere.

Many thanks!
