I have a laptop Dell Inspiron 5567 (Windows 10) and today when I open the laptop I receive that message: "Alert! 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."
Until this day, the laptop started fast and every applications started fast. And the battery is charging. Now the battery not charge and the laptop and applications started slowly.
So, I have this questions:
- The battery should be change?
- The AC power adapter should be change?
- The laptop performance is affected by the battery or/and the AC power adapter? And how can be fixed?
- If I change the battery or/and AC power adapter the performance laptop will increase (as when the laptop was new)?
Note 1: I looked for similar question and I not found something useful.
Note 2: If you need another information about the laptop, write back.
