Hi folks, As above, I have a Dell Inspirion 7737 that detects when the charging cable is plugged in but will not charge any battery. Failed attempts to fix so far; Bought new dell batteryFlashed bios to latest A17Windows fully updatedUninstalled the AC drivers, rebooted with and without battery/AC etcTried Dells driver update tool, nothing of noteBios showing AC adaptor as unknown (same for 2 different chargers) and battery shows as working normally I think it’s possibly a motherboard fault as there looks to be a shorted capacitor (P 110) near the charge port area [see attached]. Any ideas if this could be the culprit? Any advise would be much appreciated :) JohnO
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 when measuring it whilst it is still connected.
(click on image to enlarge for better viewing). Here’s a link to the motherboard 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.
