That is also a CPU failure indication for your 7510. Intel does have a processor diagnostic tool here but of course the system would have to be able to boot to use it.
hey guys i was working on my laptop " dell latitude 7510" and suddenly he went off  i tried to turn it on again but nothing happend , then i noticed that the LED was blenking with 2 color white and amber , and the signal was 1 white and 2 amber . i searched for the problem on the internet and i found a person has a dell xps blink with same signal and i read the reply and i found that the issue is a CPU failure . is it the same for dell precision as like the dell xps ( sorry for the bad eng and vocab XD)
dell precision 7510 went off
