Fix: The AC power adapter type cannot be determined –

The substantive region of a laptop that makes it portable is the rechargeable battery. Batteries have given devices the much-needed exemption of movement that world craves. however, you will need an AC arranger in orderliness to charge your laptop battery. For Dell users, charging their batteries has reasonably been a problem. There is a finical write out that has been bothering several users ; as far back as 2005. When the charger is plugged in and the personal computer is booted up, the drug user gets an erroneousness in a black riddle stating “ The AC power adapter type cannot be determined ”. A variation of this message says “ The AC power adapter type and wattage cannot be determined ” .2020 03 15 145653 The calculator will then state the electrical power of the arranger you need e.g. ‘ Please punch in a 130W adapter ’. The drug user has an option to ignore this message and complete the boot by pressing F1. This error besides occurs when you have fully started your personal computer and logged in. when you plug in your charger at this item, a presentment message comes up in the system tray stating that the AC power adapter type could not be determined. In both cases, your barrage will not charge and you will not see any indication on the organization tray that the charger is plugged in. This article explores this problem and gives you the remedies to it .

Why your AC power adapter type cannot be determined?

As the erroneousness says, this means your personal computer can not identify the charger you plugged in. The power connection consists of 3 pins, 2 are office and earth, the 3rd is a signal occupation to identify the PSU as a compatible ( Dell ) unit. If the Laptop does not get the sign, it does not allow the PSU to charge the battery, it will, however, allow it to power the laptop. This will protect the battery from high currents if the electrical power of the charger is higher than the OEM specification. If you choose to ignore this message, the system performance will go down, and you will notice that your processor clock rush has been halved. This problem can be caused by using the wrong charger. It can besides be caused when the data connection for charger designation is broken ; it could be ascribable to a problem in the charger ( cable, hack or central pin ) or in the laptop ( exponent input signal port or motherboard ). While trying a new arranger is a commodity mind, changing the battery is not. This error is not caused by the battery in any way. In fact, you will get the like error if you barely plug in the adapter without the battery.


If you have a charger that has been working earlier, then do not worry. The demerit is a coarse one and happens because the ballyhoo sits thus proud from the side of the laptop that it constantly gets knocked and causes the connection on the power control panel to fail ; most normally open circuiting the bespeak line. Wriggling it about might solve the return but impermanent. It is a count of clock before your charger will need you to plug it in in an awkward slant for it to work. finally, it will stop working all in all. You can know the beginning of your problem by trying your charger on a similar laptop, or by plugging in a similar charger. If your charger works in another laptop or the modern charger hush shows the same mistake in your personal computer, then your problem is likely to be the DC charging port in your laptop, or a bad charge system on your motherboard. If another charger works on your personal computer or your charger shows the same error on another laptop, then the problem is the charger. Below are the solutions to this problem .

Change your DC power jack

Make sure that the separate numbers ( e.g. DD0R03PB000 or DD0VM9P000 ) match or at least make sure that the electrify is the same and the units you are swapping are compatible. 2017 11 20 173047 If your laptop DC input port is soldered onto your motherboard.
