Title
Dell Latitude E7440 Hard Drive Cable Replacement
Introduction
This guide will show you how to replace the hard drive cable in your Latitude E7440/7450. If your machine is having unusual issues with sleep and hibernation not working correctly, this is sometimes related to a intermittent hard drive cable that is beginning to fail, but still works. In other cases if your drive no longer shows up, it can be due to a bad drive, cable or motherboard.
Due to the low cost of this cable (or in my case, I kept one on hand just in case I had to service the cable in my E7440), this can quickly rule out a bad cable so you can move up to looking at other deeper issues that may be causing your problem. In the case of this E7440, the machine does not properly hibernate. It has been a problem with the original Windows 10 installation, and 2 wipe and reloads. I am changing my cable as I have it available for this exact reason, and to rule out a motherboard or SSD with poor compatibility.
