3) there could be motherboard input for a battery that is used to keep RAM powered after the PSU caps run out and there was not enough time to flush data to SSD. maybe a driver could be made to write the cpu and RAM to SSD with this battery power at minimal CPU clock speed while GPU's etc buses are powered off

some SSDs already do this, they use capacitors and have power input detection, some even report S.M.A.R.T. failures if the capacitors go bad
