I have been unable to find, via HP or other sites, detailed specifications on the motherboard chipset, and UEFI in the HP Envy 15t j100 Quad TouchSmart laptop. FYI, here is a link to the HP.com website page for that particular laptop.
Maybe, I am hoping, anyone who is familiar this laptop will share whatever they know or provide links that are helpful. Thanks, Mister Smarty Pants (MSP)
