Check your bios with a hex editor to see if the BID is U70 or U71 , just do a text search for U70 and U71 https://www.badcaps.net/forum/troubl...ash#post107099
When you find which BID you have flash the bios from this post -> https://www.badcaps.net/forum/troubl...16#post3672790 .Afterwards fill in your DMI with HP BCU.

If you've already done that and you're still having problems (e.g. late display), then replace your BIOS chips...
