I guess so,
can you open device manager, go to that HDD, open its properties, and change to quick removal ?

No "Policies" inside the properties ?

hmm, got the safely remove icon for the HDD ?

It happens everytime you want to use with battery ?
Clean the connector ?

@htpkevin, CPU throttling shouldn't prevent the notebook from shutting down..
Thermal paste should last longer than that

Or try see on Event Viewer, see around the shutdown time if got any thing suspicious..

No need download

How did you do the paste?

Just type event viewer on start menu.

You used what paste ?

Since its hard, did you spread it first ?

hmm, try use hair dryer to heat it up a bit ?

It shouldn't affect the notebook when its off though..

Its the same, P4G is fancier interface for Windows power management

Some user report the 'yee yee' sound before..

Your access time quite slow compared to this one..

Not really say it failed, could be something is using the HDD, hence the slower access time..

Can you do the test after restart, with nothing opened ?

Still consistent the access time...
Could only think of to turn off APM, might reduce the access time..

What's the temperature when you doing the Furmark?
Since it suddenly reboot, most likely it overheats.

N45/N55, better GPU, better speaker, different design.
N53Sn, has 4 slot ram.

N55 Core i5 = 1600x900, Core i7 1366x768.

You can take a look at MSI GE620DX-FHD, similar spec with N55SF, but with 1080p screen.

@htpkevin, try update the AHCI driver..
