Battery Light Flashes Red Won't Charge
A while ago, the battery light started blinking 5 times, (4 times red) and refuses to charge. When I run the diagnostic (holding Fn down on start up) it says "Msg: Battery - unable to retrieve battery health".
I have since replaced this battery twice, with no change.
I have updated the bios.
I have replaced the power supply.
I ran the support assistant which correctly identified my laptop: Dell Inspiron, 17R 5720. Unfortunately, it also could not fix the problem. In fact, it said "We did not find any issues."
I installed all drivers it recommended.
I am at a loss at what else to try here?

That leaves the mainboard as the faulty part.

Yes, it does ID.. Tried several chargers.

Sounds like the issue is with the charger (does the system properly ID it -- F2 at powerup)? ... or the mainboard itself.

I have tried two new batteries, neither fixed the issue.

The battery is dead -- replace with a new one.

In the end, it turned out to be the motherboard and the only fix was to replace it. I found it for $62 here. There is a good guide on youtube on how to change this out. It wasn't as bad as I had thought. Make sure you buy some thermal paste though!
The thing is running like a champ again. Thanks everyone for your help!
