Here’s a list of security tips I have that might be useful for your laptop.
Syslinux and GRUB supports bootloader passwords. Use them.
By default, filesystem permissions allow read access to almost everything. Change the default umask to improve security for newly created mask. Use a umask of 077 for maximum security, which makes new files not readable by users other than the owner.
/homeif performance is an issue.
Use Truecrypt to encrypt data that go into cloud storage services such as Dropbox or Google Drive. Hidden volumes are highly recommended. Store miscellaneous stuff in the encrypted volume and the sensitive information in the hidden volume.
Backups should be encrypted as well.
Disable hardware that you do not use:
macchangeron each boot.
