AC adapter/charger question
My 45 W AC adapter for Dell Inspiron 15-3552 does not charge the laptop. When I plug in and switch the laptop in, "the AC power adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a DELL 45W AC adapter or greater for the best performance" pops up.

The possible causes for this are a problem with the AC adapter, the charger connector built into the system (if it's a separate item rather than directly attached to the motherboard), and the charging unit on the motherboard. In most cases, the issue is the AC adapter itself. If the system is under warranty, Dell should send you a replacement. If not, Dell 45W AC adapters can be purchased pretty easily through Dell or even third-party sellers, although technically with third-party sellers you might not be getting a genuine Dell part even if the seller claims that it is.
