By the way il tried IPA and a torch light and still cannot see, i think its a bios chip ...

Hello its me again !

I checked the board again after replacing the original component that was overheating. Now I’ve noticed that a different component is getting slightly warm (around 30°C).
When I inspected it under the microscope, I saw that it’s actually burned on top.

I can still make out part of the marking — it looks like “M?” followed by “=8L 438”, but the second letter after the “M” is not readable.

Does anyone know what this component could be or have a schematic/boardview for the Dell Inspiron 15 3511 to help...

Thank you very much, i appriciate all the help !

Can you help me with a digikey link please ?

Hi everyone,

I have a Dell Inspiron 15 3511 that stopped turning on after my friend plugged in the power adapter.
Here’s what I’ve checked so far:

No reaction when pressing the power button (no LEDs, no fan).

The power adapter works fine (tested).

One chip gets extremely hot as soon as I plug in the charger.

The capacitors around that area are not shorted.


I’m attaching photos of the board to show the issue.
Based on this, what kind of fault or defective component could be related to this overheating?...
