The symptoms look like something is shorting out your motherboard. Please check if standoffs are installed correctly and that no naked wires are touching the motherboard surface, also do check that no screws or any sort of those things are behind the motherboard

Bad keyboard, maybe a bad motherboard. A tech can fix it, if it's worth the parts & labor cost. Otherwise it might be time to get a new laptop (or send yours in for warranty service, if it's still covered).
