lenovo n22 ideapad keyboard not working in BIOS, bootloader

Lenovo N22 80S6 thinkpad touchpad+keyboard not working in bios /anywhere including "live cd" of #! , mint ,tahr puppy. minino.
both touchpad and keyboard worked from date of purchase 11/2016 til last week in linux mint 18 after got sdcard reader working / did system updates. i had just finished resolving the matter of the sdcard reader not working so i suspect that process is the number 1 culprit but there were so many steps taken to get that fixed that i have no idea how to undo that work even if it would fix this problem.
info accumulated after researching this for past week:
uefi system
SKU Number: LENOVO_MT_80S6_BU_idea_FM_Lenovo N22 Family: IDEAPAD

tried:
Checked for any bios settings regarding touchpad or keyboards (bios has only one setting related to touchpad+keyboard which ws for enabling function hotkeys , i disabled, rebooted = no chg, re-enabled, rebooted= no chg )
unplugged external keyboard and rebooted
upraded from mint 18 to 18.1 to attempt fix but failed
neither touchpad nor keyboard working when doing this:
Fn + F8 touchpad lock/unlock
Fn + F6 keyboard lock/unlock
booted into livecd
changed bios seting from uefi to legacy and that let me boot into other live cd's but neither touchpad nor keyboard worked there

Other Notes:
External usb keyboard&mouse work perfectly
The laptop keyboard&touchpad worked unti ~3/14
No recent changes come to mind that could've triggered this. Maybe a linux update?
BIOS menu can be entered (fn+F2) using the usb keyboard, but it can't be used for anything else

brings up mouse and keyboard settings but only shows usb ones:
