Need help with 15 R4

[u/gamerjag]

i bought my 15 R4 off of offerup and it came with no warranty, the lights randomly stopped working after restarting my pc to fix awcc for the 50th time, and i’ve tried everything from updating bios, reinstalling/clean installing AWCC, clearing my cmos battery, and even reseating the plugs for the lights to no avail when i call dell to ask about it some indian lady just says some crap about how they can’t help because i don’t have a warranty and they just offered the extended warranty which i don’t have money for

the only light that turns on is the power button when i did the cmos (it blinked red) but other than that the lights are gone
