I'll try that tomorrow and follow up on this.Īt this point though, I'm beginning to wonder if in-fact the Dock is the culprit. Verified all audio is turned up to it's maximum whatever program playing audio was turned up speakers have no physical volume buttonĪs I'm typing this, I've realized that I have not attempted to try this in Safe Mode for kicks.Verified good connection to dock in the proper ports.Note that audio comes out of the laptop when set as default, but no audio on speakers if they're set to default.

Verified audio output was set to external speakers, not the laptop's.Updated the BIOS to its current version.Verified speakers work by testing on multiple devices.Reinstalled all audio drivers multiple times both from the Device Manager doing an auto-search for the missing driver(s) and using Dell's own driver check.The external speakers, Dell AX210, plug into the dock (both the audio and USB cable). I have a Latitude E6440 that is normally docked 90% of the time and will not produce sound through my external speakers, only through the built-in laptop speakers. 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.I've spent well over two days on this issue and I am completely stumped. 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. 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. 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.
