Impact Computers and Electronics provides an unbeatable warranty period of 30 days for our parts! For those clients who want piece of mind for one to two years, our Extended Warranties provide the coverage that you need at an affordable price! The OEM power supply says it can provide only 18 amps. Unfortunately when it comes to the industry of replacement parts, there isn't a manufacturer who guarantees the product. This power charger is compatible with the Dell Precision M6500 & M6600 models and Alienware M17x, M17x2, M17x3, M17xR1, M17xR2, M17xR3, M18x, M18xR1 and M18xR2 models. In normal circumstances, during the original manufacturer's warranty period, most repairs will be handled by the manufacturer. Replace your worn out Dell power charger with a replacement AC power adapter for Dell Precision and Alienware Laptops.
