Laptop cuts out after launching a game

Guffy

Is there anyway to narrow down this issue?

The battery stopped charging about a month ago but is working grand plugged in until i decided to launch a game this weekend and it cuts out during the loading screen.

I tried resitting the battery and it begun to charge for a min or two but stopped again.

The cable is fairly loose in the port, not the one that came with laptop, looks like a generic one that i got from laptop store a couple of years ago but has always worked.

The port itself doesn't seem loose and the pins all seem to be fine visually.

Is there a log somewhere on the laptop that will identify the reason for the power to knock off or do i just have to replace the parts 1 at a time?

I guess i should prob see if fans need cleaning out too.

If the laptop came with say a 90W PSU and you're using a 40W one now itll work for light use but won't have enough power for full tilt (gaming). Thatd be the first thing Id check. Back of the brick should indicate its output.
