Dell Charger Issues

[claytonpinter]

Hi. I recently purchased a Dell Inspirion 15 i5779, and it's crappy charger broke. I purchased a DENAQ ac adapter as a replacement. All was well. No errors during startup, charged like it was the original. But, last weekend, I had a friend over and he had his laptop plugged into the same surge protector and now, at startup, it warns that the wattage can not be determined, and that it will not charge. I don't know if this is an issue that can be resolved, but can someone point me in the right direction? The charger has a 1 year warranty.

Charger specs
19.5 volts 6.7 Amps

If the charger is under warranty, have them replace it. However, in the future, you really should stick with an OEM part rather than an aftermarket one. Those are very hit and miss.
