Hello,

I have a latitude E5540 and unfortunately whenever I connect the power the light goes out on the PSU. I have tried from battery and it still won't switch on. I assumed it may be shorting on the case soemwhere. I have stripped it down and removed the motherboard but still the light goes off when the psu is connected to the jack. Unfortunately it is outside of warranty, is there an easy way to determine if it's a single component which has failed which I could remove and solder a new one on?

Any help would be appreciated.

The sad bit with laptop motherboards, is that you will need a certified technician to verify the issue. To me, it's as if the power brick is failing at it's duties, provided what you've explained is the power bricks LED and not the power indicator LED on the laptop.

Unfortunately the power brick is ok as I have tested it on another laptop. I guess it needs a new motherboard or I take it to a specialist.
