USB-C charging problems on 15.6" Lafité IV. BIOS updates?

Love the 15.6" Lafité IV - but I have found a few issues with USB-C Power Delivery. Most PD chargers work well, but a few don't negotiate power properly.

I've tested chargers on Chromebooks and ThinkPads - they work fine and deliver up to 65W. But on the Lafité, power negotiation sometimes gets stuck at a much lower power. I've tried several different PD cables and chargers.

Is their a BIOS update - or similar - which can be used to improve the situation?
