I'm not on a laptop but I've been running ext3 very successfully for about 7
months. It's based on the tried-and-tested ext2 so it's pretty robust. ext3
is also forwards and backawards compatible with ext2, so if there are any
problems you can mount an ext3 partition as ext2.

just run:
tune2fs -j /dev/hdaN
where N is the partition number
Load /etc/fstab into a text editor, and change the 'ext2' to read 'ext3'.
Reboot, check it's now mounted as ext3, and you're done :)

The switch to ext3 is non-destructive.
Of course you should be doing backups daily anyway ;) (hrm, that's rich from
somebody who hasn't backed up for ages :().

As long as ext3 is compiled into the kernel, you don't need to do any more. If
ext3 is compiled as a module you may need to mess around with initrd stuff. I
compile ext3 into the kernel because it's easier, IMHO :)

Hear what exactly? ;)
