I have a Dell inspiron laptop with windows vista. It has been working perfectly until lately, a problem has been bugging the hell out of me. Ever minute, a USB safe removal notification in the battery/time bar keeps popping up. It disappears instantly. The sound also plays every time. This by itself didn't bug me, until it started to slow down my computer momentarily every 5 seconds or so. This also happens even though there isn't a single usb plugged in (including mouse, printer...) Please help. Thanks

  • I do have USB devices installed, just not plugged in at the moment. – Laurent Jun 18 '14 at 12:10
  • Then, the answer is no. But when I plug the mouse, etc. in a usb socket, it still works. – Laurent Jun 18 '14 at 12:17

As Ramhound mentioned it's always a tussle of trying to find out if its hardware or software that's causing the problem.

If you load your Device Manager in Windows you can expand down Universal Serial Bus Controllers and double click on each USB Root Hub then click on the power tab within here you will see if any devices are 'plugged in' (or at least se if Windows thinks they are plugged in).

Within the Device Manager you can also right click on your USB Host Controllers and uninstall them, restart your machine and they will re-install, giving them a fresh install could solve the issue.

Finally reinstalling Windows might solve the issue but not if the issue is hardware.

Sorry I know this is not an 'answer' as such but too long for a comment, hope it helps.

  • I tried reinstalling the USB controllers, but that didn't solve it. By reinstalling Windows, do you mean a reset? – Laurent Jun 18 '14 at 12:44
  • Nah would be a full Windows re-install which can be a pain, most people do not have the Windows media or a method of backup to safely store their data, etc. Did you check each USB Root Hub to see if all the power tab list is empty? If you was to go in to that list and right click disable on all the USB devices (of course your mouse, etc. will stop working) but does the issue stop as well? If so you could try to narrow down which of the Controllers or Root Hub is the problem one? – CharlesH Jun 18 '14 at 12:47
  • Thanks alot, seems to be one of the root hubs, i disabled it. Thank you so much! – Laurent Jun 18 '14 at 12:56
  • No problem glad to help :) – CharlesH Jun 18 '14 at 13:10
  • A downvote for an answer that resolved lead to resolving the issue... good one.... – CharlesH Jun 20 '14 at 12:10
