m15, 1.5.2 Update is running for hours!?

I just got my M15 yesterday. Ran windows update and driver update -- everything went well. Last update is the BIOS to 1.5.2! It has been running for more than 2 hours as if nothing is happening. Is this expected? Anyone tried to update to the same BIOS level?

(BTW, I already called AW Support -- they say to leave it as is. However, fan is not running and laptop is already HOT! I just had a desk fan pointed at it just to keep it cool).

Help!
