Hy,

It's normal that the Dell 19.5V ac adapter's voltage fluctuating between 16 and 19.5V? The fluctuating: the starting voltage is 19.5V, and decreasing 0.2V per second to 16.5V, and the voltage jump 19.5V, then decreasing again to 16.5V.

Can I use the laptop with this adapter still?

THX :)
 
While you can still use it, for now, it will start to have trouble powering the device and charging the battery at the same time. Were it me, I would get a new one now, rather than later. Just be sure to get a good OEM one and not aftermarket.
