For some reason my Acer will not run off of the wall electricity, only battery!?!?!?! And that runs out very, very quickly?! Does that mean I need a new power cord? TIA!!!

    Yes, probably need a new larger power adapter, If you have the 2019 model it is possible the adapter is bad., also check the adapter barrel pin on the DC cord if it fits properly in the laptop port, when you wiggle the adapter plug when inserted does the LED charging light comes on? Check the port and plug for dark/burned spots. Check with a multimeter the DC output voltage of the adapter.

    Your laptop has a burnt out mosat, capacitor or a resistor in its main power stage rail, its got nothing to do with your adapter charger or battery. If you want to be 100% sure then test the adapter by using a multimeter, the adapters plugged into the mains barrel plug should read 19.5V with the + RED prong on the inside and the - on the BLACK prong on the outside of the barrel plug, if its working 100%. Take your laptop to a technician that specializes in fixing laptops as this is an easy fix, do not try and fix this yourself as you can't as you need specialist micro soldering tools. Good luck and hope this helps you out.

    A technician needs to follow the DC_IN port trace on the mainboard to detect where the shorted circuit is, as that is the problem that your laptop is having if its not charging from the charger adapter, its a complex job and you need experience to fix this problem.

    If you have a multimeter, it will be easy to test out whether the adapter is bad or good. Turn the knob to DC voltage measuring. Use the red probe to stick into the inner charger pin. The black probe will be touching the outer metal barrel. The meter should display 19-19.5V. If it displays lower like 17→0V, then replace the charger.

    If you do not have the multimeter, try to plug the charger into the outlet and hear a small spark (the charger does not plug into the laptop), the spark might mean that the charger is fine. Or take it to an electronics shop and let the technicians test it.
