Hi all.
About 2 weeks ago, I lost the ability to control Lights on the front and back etc of my 730 and fans got stuck on 55%,
After trying the usual suggestions from Dell tech, Bios update etc, an Engineer came out last Saturday and replaced the Master I/O board and that solved that problem, but what I had noticed and even though I reported the following error from the Dell diagnsotic I was asked to do for fan problem, the one you do at boot F12 option, it reported Error 6500:041b , USB controller not generating Interupts. Both Dell tech and Enginner didn't know what to make of that,. Well I now feel I know what it may be, if I disable the USB controller in the Bios, the system loads the bios screen as fast as normal, but of course I do not have any USB devices in Windows. If I leave it enabled, it takes a good minute or two to get past bios screen.
I have reported this to Dell Tech, and they tell me because I have just had a engineer out, I have to wait for 7 days until another one, now my warranty is toplevel, 24/7 support, next business day onsite. Why do I have to wait 7 days. I am cocnerned this is a problem they may be indicating a Mainboard issue and explain why this system randolmy restarts itself no matter what I am doing.
To add, until Vista Device Manager, I see one USB device not fully installed, it is called "USB mass Stoarge Device - Universal Serial Bus controllers. Error msg is
his device cannot start. (Code 10)
Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available.
I check for solution and Windows says drivers cannot be installed.
I am running Vista 64 bit, but problem was also there under 32bit version and is also there under my other drive, WIndows 7 64bit
I would imagine windows cannot install driver etc, as the problem is Hardware related, but I cannot say for sure.
Where is the USB controller, is it on the motherboard?
Any thoughts or suggestions please reply.
Thanks
Phil
Hi, sorry to reply to own post, but I found a solution, well it may only be a tempoarly one.
It was posted in another forum, link of which I thought I had kept, but it didn't save in my favourites,
Solution was
Turn off computer, take power lead out of box, hold start button of PC for 30 seconds and then plug poweer back in and restart computer, sure enough this fixed this issue.
This would also explain why over the last few months whether I have been web browsing, playing a game or listening to amusic, that a move of my USB wirless mouse, would lock up the system. This USB controller.,
Now I reported this to Dell support and someone else replied and the informaiton he told me, was very similar to what I had done. It is.
"Dis-charge Startup the system - Remove the AC Adapter from the system - Remove the battery from the system - Press the power button for 10 seconds - Insert the battery and AC Adapter back into the system - Try to start the system and take note of the performance"
He said this in relation to a laptop, good grief, don't they read emails, I was talking about a XPS Desktop, sheesh!!
I am not 100% confident problem is fixed, as earlier this evening, I heard the noise you get when hardware is install, when I logged back into my Vista drive after about an hour or so of none use.
It does concern my Mainboard might be going to go one of these days,although I have not found out if USB on board controlelr is actually on MB, but I would assume so.
Of course if this USB controler totoaly packs up, I have Blue tooth keyboard etc and of course my monitors have USB inputs.
Actually I may use BT keyboard / mouse over the next few days and see.
I hope this may help others and any input from other XPS users, I would like to hear.
Cheers Phil
