The problems at the U.S. outlet store began Friday evening, according to posted to the NotebookReview Web site, and the site was still down Saturday evening.

"I tried last night and early this morning to view the inventory on Dell's Small [Business] website but I kept receiving an error message," a user with the screen name Stevoreno wrote on the NotebookReview.com forums Web site Saturday morning.

Dell did not respond to requests for comment. A customer service agent on its support line said the U.S. store was having "technical issues" and that the company was working to fix it.
