To get the serial number of the hard disk without taking it apart, you can try booting your laptop from a USB drive or CD/DVD with a Linux live distribution, such as Ubuntu. Once booted, you can use the command `lsblk` to list all the block devices, including the hard disk, and then use `blkid` to get the UUID and serial number of the hard disk. This way, you can avoid taking apart your laptop and still get the information you need.
