Software solutions require a functioning motherboard and processor to run the wipe commands. If the laptop is dead, the drive must be removed and physically destroyed. For an HDD, this involves driving a nail through the platters or using a drill. For an SSD, the user must ensure the chip (usually a black rectangular component) is shattered.
