Pavilion laptop shuts down?

I have a Pavilion N5415 which has started shutting down, increasingly
quickly after start-up. It started with the unit doing this after about ten
minutes use. Now it probably wouldn't even run a diagnostic boot disc (if
one exists? Thinkpads used to be very good on diagnostics of every single
part of the hardware from some special boot partition accessible from the
BIOS start).

It does it on battery or AC power, in XP, safe mode AND on Linux.

Shutting down happens just after a click from the right hand far corner of
the laptop which sounds to me like some kind of protection circuit cutting
in or power supply giving out (or of course both if the former means the
latter).

Does anyone know:
which one this is and?
whether it is possible to dismantle the unit? and
whether there are any instructions on line? and
where to get a power supply, if that is what it is?

There don't seem to be any internal parts on ebay (or am I looking in the
wrong place?)

Spontaneous shutdowns are often a sign of some sort of heat problem in the
computer. Start with a can of compressed air (from Staples, OfficeMax, Circuit
City, Best Buy, etc), and, with the computer powered down, find the intake and
exhaust vents for the air taken by the system cooling fan(s). Blast compressed
air inside. If you see a puff of dusty air exiting from a vent, you may have
nailed the problem.

Some disassembly may be required to solve the problem. Someone else may be
able to help you find a service manual for this model... Ben Myers

I did that with my Inspiron 8200 and had to take it apart to get the dust
OUT as opposed to pushing it further in. I was wondering how you dismantle
a Pavilion and whether there are instructions on line as this does seem to
be some protection circuit kicking in.
