I have an issue with my ac power and battery working together. When my laptop is without a battery, it runs off the AC power cord fine. When I attempt to insert the battery it stops running of the AC; it actually does not see the AC power supply anymore, in fact, it would switch off if I took out the battery. Any ideas on how to solve this?
Initially, I thought it was a problem with the old battery. But I now understand it was switching off immediately with the old battery inserted because it had no power. I bought a new battery that came with a 50% charge with which I discovered this.
What I have attempted:
- resetting the battery
- using new battery
- updating the drivers
- updating the BIOS overcoming the requirement of having both AC and battery to do so thanks to this
- using a new AC power supply
My laptop is a Dell Latitude E7240 running Windows 7
Edit 1: There does not seem to be any power drawn from the battery while it is plugged into the AC supply (even if it does not see it). After a few hours, it is still at 50% and estimates 2877hr and 34min
Edit 2: Please see the two pictures below. What does it mean? the laptop cannot see the AC power even if it is actually powered by it?
Edit 3: I bought a new AC power supply but the problem persists. When plugged in with the battery, the laptop does not detect it. Any idea what the problem might be and how I can solve it?
