My Inspiron 15R SE 7520 from August 2013 is completely dead. The AC adapter LED is green when I plug in the power cord while not connected to the laptop. If I connect the adapter to the laptop the LED turns immediately off. That happens even if the accu is removed from the laptop. From that I assume that it is not a problem of the accu, correct?. Measuring the AC adapter output shows 19.5 Volt as specified. Maybe a problem on the mainboard?
Does a fix still make sense given the 4 years age?
There is some interesting data on the hard disk that has not been backed up. Is there some service to get the files from the disk? The data is not super critical, so how much does such a service cost - rough estimate?
