Dell latitude 7390
Latitude 7390
Hello All,
Ive come to see if anyone else has any issues with the 7390s we recently bought a Lot of 30 of them and even more recently another Lot of 40. Well for the past month we probably have had at least two a week fail. Ive been opening up support cases for each one and it seems like the mobo needs replaced everytime one of them fails.
Well after opening up cases on the most recent two I decided to take a closer look at the board it seems like the same chip is burning up on both the toasted laptops I have in my posession at the moment. Im not sure how closely Dell support looks at this site but this is a serious issue.
I run a small shop so dealing with two laptop failures a week along with this happening the same time my windows 10 migration is happening has been really taxing.
Also the main equalizer seems that they are all failing when on the thunderbolt dock. We have filtered and stable power so power is also not the problem.
IC thats burning up
ICs location relative to the rest of the board
I have 30/35 pieces whit this probleem. I need help , thanks

These would have had to be purchased used, so you need to contact your supplier to find out whether they were sold with any sort of warranty.
These systems were released in 2018, meaning they're end of life to Dell - - the design life of a notebook computer is five years, and failure rates can markedly rise at or around that point, so it becomes difficult to determine the cause. Any system that reaches five years old is on borrowed time -- they're just not designed to last longer than that. That is not unique to Dell -- it's industry standard.
