You flashed the BIOS to fix that bug? You is craaaaaazy!
I didn't, the Dell rep did
. And believe it or not I forgot to cross my fingers, but everything went fine
I'll update BIOS in the first couple of weeks (thank goodness BIOS is dead/dying) but, after that, I want to know everything that's changed before I update it on hardware I rely on. To this point, I've never updated the BIOS on any of my computers outside the 30-day return policy. I don't find it inherently risky per se but it's just a sensitive process and difficult to roll back.
So, as a side note, be sure to read the entire changelog before updating. You may find "Updated to speed up fan 20% under heavy load" is not worth the update if you just use the PC to check email. Also, if there is no changelog, consider a different OEM next time.
With that said, I'm glad your laptop is working as expected now.
