![]() ![]() Let me know your thoughts Dell community.Īfter disabling the USB ports on Device Manager the notifications stopped, unfortunately the user won't be able to use any USB-based device. Although I'm not an electrical engineering I'm open to any suggestions. A "Intel(R) Corporation - HID Class - 12:00:00 AM - 2.2.1.377" update was also installed and all other driver update Windows Update searched for.Īfter all of this I think there's a likelihood the system board has some power issues.I did a firmware update to the current version 0.1.23.1.As you can see by the weird USB icon not native to Windows (see image 2), there's some weird manufacturer driver that persists after a disk format and clean install. I did a clean reinstall of the operating system.I tried a Windows PE and it didn't prompt for the error.I have disabled the " Allow the computer to turn off this device to save power" checkbox in Device Manager for all the USB port drivers that appear.I have made a deep troubleshooting on the device, from which: How to fix laptop usb ports not working dell latitude e6440 laptop usb not recognized solutionusb ports not working dell latitude e6440 usb not rec. You will probably want to buy a new one within the next couple of years, so in the end it is better to save those 1-200$ now towards a new model than shelling them out now.A user with this laptop presents the error code above (Spanish) that basically stays that a power overload has occurred in the port. ![]() Hear me out on this one: the hardware inside is already 4 years old (not saying that it is slow or anything). If you try to do the same, I believe that you will get similar results as me, that's why I recommend replacing the motherboard entirely.įinally, I still believe that replacing the motherboard is a better option than buying a new laptop. Now about a possible fix: I too tried fixing the thing with some board level repair: I unsoldered the faulty USB port and replaced it, but the new one did not last, then I replaced the board. I know that you have a different model with a different board layout and that yur problem is with the main board, but hopefully this confirms the theory that this problem has been there for some time. I've had a similar problem with a E6420, fortunately it was not the main board, but a secondary one that needed replacement. Dell Latitude E6440 14 Genuine Laptop USB VGA Video Port Board LS-9938P Description: The Item was tested and carefully removed from the working laptop. ![]() While a motherboard is hard to justify, I'm hoping the motherboard I currently have can be repaired at the board level.Īre they any known issues with these motherboards? If so, does it impair a long term repair? The motherboard is nearly as much as a entire used laptop with the same CPU (4810MQ/IGP+8790M). While I'd LIKE to repair the system with a new motherboard, it doesn't make economic sense. To get the motherboard from a good vendor that will back it, it would cost me $200 for the bare board from PartsPeople.This would be in better shape too, most likely. A complete i7 E6540 can be purchased on eBay for $300-400.I can already see a new board is just as much as a whole computer, as you can also see here: Obviously I'm hoping it's just a bad part lot but I also can accept it's not a defect that can be corrected to the point it won't come back. Is there a way I can fix this permanently or is the defect unrepairable? Seeing as this is the second board with this issue, I believe Dell had a bad run of parts or the boards have a serious design flaw. I forgave it the first time thinking it was a DOA board, but 2 failing the same way is a little suspicious and may point to a hardware design flaw. This is the second time it has happened, and now I'm out of warranty. I am using the same procedure as I did the first time. When this happened the first time I tested it with two different devices and determined it was caused by a bad motherboard. I have confirmed it happens with my printer over USB (HP M401n) and Xbone Wireless receiver. The last time it happened Dell replaced the motherboard. I've had this happen befire under warranty, so it's not a new defect with this series of machines. Fast Dell Latitude E5470 HD Business Laptop Notebook PC (Intel Core i5-6300U, 8GB Ram, 256GB Solid State SSD, HDMI, Camera, WiFi, SC Card Reader) Win 10 Pro (Renewed) 1,699 156.00 156. What happens is if I plug anything into it and touch the connection the wrong way, the device will disconnect and will not work again until it is plugged in again. ![]() So my Latitude E6540 has an issue with the USB port on the HDMI side. ![]()
