Thanks for the teardown information. My daughter’s 13-ae013dx has been getting the 90B critical fan error since day 5. We never sent it in for repair because she needed it for school and it was still working. Now it’s out of the warranty period and I’d like to see if I can fix the fan(s) myself. If you get to where you can see the fan part numbers I would very much appreciate some part numbers!

Note that Dell Inspiron 13s have had a rash of bad batteries that swell as they age, causing them to press hard against the trackpad. This can cause it to track poorly or make it difficult or impossible to left or right click the pad. Replacing the bad battery often fixes these kind of trackpad issues on these models where the battery is directly under the trackpad.

Same here, SmartCam has constant red light, powering it down and back up or resetting I can sometimes get blinking red. WiFi button will sometimes give yellow light, but the WiFi does not show on my phone’s WiFi list. I’m trying a direct Ethernet connection now, maybe that will help it access another firmware update?
