Has anyone else had the following issue since upgrading the BIOS to 1.21.0? It looks like they've introduced a video fan check during boot. Laptops obviously don't have video fans and so the check fails and displays an error (see below - I've blanked out my service code btw). It also delays booting while it's trying to test the non-existent fan, which is a pain. I've had to revert to 1.20.0 for the time being.   ePSA Alert
