Under siege from rivals such as Hewlett-Packard ( HPQ), Dell ( DELL) is trying to make itself a more customer-friendly place.

As part of that effort, the giant PC maker plans to largely replace its plethora of promotions and rebates with generally lower list prices, said Ro Parra, senior vice president of Dell's home and small-business group, on a conference call Thursday. The company is also extending the warranties on its computers and expanding what's covered, Parra said.

The moves follow the company's previously announced $100 million effort to bulk up and retrain its customer support staff to better handle inquiries and reduce phone hold times.

"It became increasingly clear that a simple pricing and sales structure would make it easier for customers," Parra said in a statement "We'll continue to offer customers the best value every day with excellent support."

He added on the call that Dell is "pleased with the early results" of its customer-service moves.

As part of the moves announced Thursday, which Dell previewed earlier this week, the company plans over a period of 12 to 18 months to reduce by 70% the number of promotions per product line and by 80% the number of promotions it offers on individual products. The company plans to implement the program beginning in August with its televisions and Inspiron notebook computers.

Rather than making an immediate cut in its promotional programs, Dell felt a long implementation time would be simpler for its customers, Parra said.

"We're making some pretty dramatic changes," he said. "We want to do it right."

The moves will have little effect on the ultimate price that most consumers and small businesses pay for Dell products, Parra said. But they should make the buying process more transparent and less complex, he said.

One of the problems with all of the promotions going on now is that customers feel like they never really know if they're getting the best price, he said. The new system should be much more transparent, he said.

In addition to reducing promotions, the company also plans to decrease the number of rebates it offers on its products and to move from a system of mail-in rebates to allowing customers to electronically file for them.

Dell is making changes not just to its pricing policies, but to the warranties it offers, Parra said. The company is extending the warranty coverage on its computers from 90 days to a year. What's more, the warranty will now cover any operating-system issues customers may have, he said.

The company reduced its warranty coverage from one year to 90 days and stopped covering operating-system problems in the recent past, Parra said. Both moves were a "mistake," he said.

The customer-service efforts follow Dell's recently disappointing financial results and its loss of market share to rivals such as H-P. Dell already cut prices in May in an attempt to try to maintain sales.

Dell's pricing move echoes a trend in the auto industry where many dealers have moved away from negotiating new car prices with each customer to a model of a lower fixed price for cars, dubbed "no-haggle pricing."

While some auto dealers have been able to boost sales over the long-term with such pricing schemes, many have found the shift to be disruptive as competitors lure away customers promising sweeter deals. But Parra indicated that Dell didn't expect similar disruptions.

Investors seemed to shrug off the announcement. In recent trading, Dell shares were off 11 cents, or less than 1%, to $22.27.
