The AC adapter is typically irreparable. Changing it out with a new one is the only remaining alternative. 


Make sure the replacement adapter you buy has the same wattage, voltage, and current as the old one before replacing it.

2. Check DC Port

This error may occur if there is damage to the DC input connector that the laptop uses to connect the charger.

Consequently, removing the DC power jack is simple. If it is soldered, a soldering iron is required to remove the solder.

Occasionally, the laptop's surge protector may be the problem rather than the AC adapter itself. 


Your laptop could not recognize the AC adapter if the surge protector has any short circuits. 


Instead of employing a surge protector in this situation, you can make direct connections to the wall outlet.

4. Verify BIOS

The battery and AC adapter status can both be found via the system BIOS. The F2 key can be used to access the BIOS as soon as the machine boots up. 


Only if it is being recognized will the battery and AC adaptor be mentioned in the BIOS information. 


You should attempt contacting the manufacturer if the AC adapter is connected but is not recognized by the system.

5. Update BIOS

Updating the BIOS has sometimes worked to fix the issue "AC power adapter cannot be determined." 


Since the manufacturer's website has the possibility to bypass this problem, access the system and update the BIOS. You must force update the BIOS if the battery charge is too low.
