Me too and after update bios my laptop sometimes bluescreen error. So sad :mansad:

Don't mean to hijack but it seems relevant, I've got a HP ProBook 470 G1 here and also recently installed the bio update L74 Ver. 01.43 and are now seeing lots of errors in the event viewer and more worryingly the odd Blue Screen of Death. 

I presume this update is something to do with the Meltdown/spectre exploits, either way the timings of the errors exactly coincide with when the bios update was installed and we're seeing them at least every minute. 

Anyone know if we can roll back this update? 

The errors are:

Further to my expericend with this, I've been able to install the biod version 01.42 over the top of the newer one and it now seems to have at least resovled the warnings in the event log I was gettings. Whether it's cured the BSOD's remains to be seen.

It's fixed with bios ver. 1.44.
