My first guess would be that the system is overheating. Laptops are
prone to becoming clogged with dust, especially if you have pets or a
hairy girlfriend.
If you're up to it, open the unit up, and blast out any dust bunnies
with a can of compressed air. If that's too scary to attempt, you can
try forcing air through the intake or output of the laptop's
ventilation, or take it to a qualified technician.
Heat may not be your problem, though, so I would eliminate some other
candidates. If you have a memory expansion in the system, take it out
for the sake of testing. Also, remove the battery and just run off of
AC power. There's not much else you can do without opening the case.

Is there a temperature display in the BIOS screens ?
Enter the BIOS when the computer is first turned on, and
go to the BIOS page where the hardware monitor is featured.
Watch the CPU temperature readout. Does the CPU temperature
rise steadily without stopping. Is the fan running all the
time, trying to keep the machine cool ? That could be a sign it
is overheating.
If you look on PDF page 125 here, there is a "thermal cover".
If you remove the thermal cover, you can clean dust or hair
from the area beneath the cover, to help ensure that air can
move freely. You do not have to remove the heatsink to do this.
Removing the cover, and visually inspecting the area underneath,
should give you a good idea how much cleaning is needed.

funnily enough my HP laptop has been doing the same thing .. shutting down
without warning when using resource intensive programs .. like media player
for example.
I haven't got around to cleaning the heatsink/fan yet, as the problem has
abated somewhat since I blasted compressed air through the fan vent and
displaced some dust.

Sounds like your laptop PSU (power supply) is going out. I would
recommend making sure you keep an up-to-date back up of the stuff you
want to keep. My second guess (without looking at it) is if the
shutdowns are very random it could be a memory sim/module gone bad.
