Why An DC Adapter Won’t Power My Laptop 

  • Are you using a compatible Dc Adapter on your laptop? 
  • Your Dc adapter was probably damaged by voltage fluctuation
  • Did you remove the laptop battery? 

The reason why your Dc adapter won’t power your laptop is probably due to voltage fluctuation, you remove the battery or compatibility issues,  and since every electric device has its own specific plugin adapter, with a specific output voltage and power level it can sustain by design.

Plus each and every laptop model adapter power is different and uses a lot more power than your regular smartphone,  tablets, and other small electrical devices.

 Are you using a compatible Dc Adapter on your laptop?

Are you using a  DC adapter that is compatible with your laptop model? normally the  DC adapter to use is the same input and output slated by manufacturer no more no less if it’s more powerful can put out more and cause damage to your laptop while when too low might not be enough to power your laptop or even if it power on may cause it to malfunction ie. freezing or might shut down randomly.

If you are using a  dc adapter with incorrect or sufficient current capacity can cause your laptop to not power,  you want to make sure that the voltage is correct and the current is sufficient if not things are going to fail,   see, one thing to understand is that not all  DC adapter is the same, yes it might have a two-prong and a wire and maybe, it’s black doesn’t mean it has the right voltage and or power capability to power your laptop.

Your Dc adapter was probably damaged by voltage fluctuation

Maybe the  DC adapter is damaged probably by voltage fluctuation,  this can happen if you are plugging your adapter directly into the socket not using a Surge protector or UPS  to protect your Dc adapter from direct voltage input current can cause burnout when voltage fluctuates. Lightning is another damage that can easily be mitigated simply by using a quality surge or UPS.

How Do you know an adapter is damaged by voltage fluctuation?

To know the Dc adapter is damaged by voltage fluctuation, if it burns then the smell is evidence and the capacitor itself might be affected, you may also see sometimes like liquid electrolyte from the busted capacitor,  if it doesn’t burn then that is when the output level is low than normal,   so the end result is that it may not able to power your laptop or may cause it to malfunction,  here is how to repair a laptop adapter damage by voltage fluctuation. << ===

Did you remove the laptop battery?

Another thing you want to take into account is that each and every laptop comes with a different design and characteristic so not all laptops can have the battery removed a terrible design in some laptops might cause this if the battery is removed,  so aside from the difficulty of removal (ie, having to remove screws and panels), some newer laptops won’t even power up if a battery is not detected. According to  Braden Dodge (Owner/Operator/Consultant at Braden’s PCs). 

Why DC Adapter Won’t Power My Laptop: Final thought

  • The reason why your Dc adapter doesn’t power your laptop  is the fact that:
  • It has voltage fluctuation damage
  • You remove the battery from  the laptop
  • or maybe you are not using a compatibility adapter
