Laptop shuts down randomly

[hubertwee]

Hi, my R430 Samsung laptop randomly shuts down within 1 hr of booting up, even with very minimal usage. No blue screen. Power light is either red or red flashing with amber. Battery has been dead for a while so I just run it on power.

Is it most likely an adaptor problem, or a motherboard short circuit ? Thanks

you would need at least another power adapter/battery to test with.
I am leaning towards the adapter.
