Hi @jollyboyjohn ,
Are you sure that it is a capacitor?
What is the designation next to it? I cannot make it out as it has been partly obscured. It shows ?5401 (see image below). Knowing the designation will tell you what type of component it is. Maybe you can clean it up and see what it says by gently wiping over the designation using a Q-Tip lightly moistened with clean water. Just don’t make the board too wet trying to clean it up.
If it says C5401 then it is a capacitor. If not then F=fuse, R= resistor, RN=resistor network, L= Inductor, D=Diode Q= transistor, just to name the more common designations found on a board
-Have you measured it with a DMM’s Ohmmeter function to test if it is short circuit at all or even open circuit? You may have to remove it from the board in case there are alternate circuit paths around the component which may give false results.
+Have you measured it with a DMM’s Ohmmeter function to test if it is short circuit at all or even open circuit? You may have to remove it from the board in case there are alternate circuit paths around the component which may give false results when measuring it whilst it is still connected.

Here’s a link to the motherboard [link|https://www.alisaler.com/dell-inspiron-7437-7537-7737-12311-1-doh50_hw_ult_mb-reva00-schematics/|schematics] that may be of some help. Check that the board number of your board (printed on motherboard) matches the board number as shown in the link i.e. 12311-1-D0H50_HW_ULT_MB REV:A00 in case yours is different.

What is the designation next to it? I cannot make it out as it has been partly obscured. It shows ?5401 (see image below). Knowing the designation will tell you what type of component it is.

If it says C5401 then it is a capacitor. If not then F=fuse, R= resistor L= Inductor, D=Diode Q= transistor, just to name the common ones found on a board

Have to measured it with a DMM’s Ohmmeter function to test if it is short circuit at all? You may have to remove it from the board in case there are alternate circuit paths around the component which may give false results.
