Well, aside from the problems with dirty buffers being written
to disk, I can think of mounting your filesystems with the
option noatime.
This way, your laptop harddisk won't be writing updates to the
acess time of files whenever you read a file, for example.
I guess that this update contributes to generating things to
make the buffers dirty and Linux is writing this information
to disk to try to keep the metadata of files in a consistent
state with the acessed files.
