I have a Dell N5010(Inspriton 15R) laptop. The laptop will run for a while (10 mins) then cut out, I at first thought this was a overheating issue. This issue still happens even the the BIOS
I've tried the following
Replaced the thermal compound.
Cleaned the fan out
Tried running the machine with nothing connected (apart from the fan and power button)
Tried running the machine with nothing connecting while alternating the ram chips
Replaced the daughter board that has the power jack etc (Link)
The laptop was working before I left for a trip when I returned 6 days later it had developed this issue.
