Question

Plugged in not charging

My Dell laptop running widows 10 w latest update will not charge the battery. It says “plugged in not charging”
I have tried online cures including reload drivers resets for battery drivers, bios settings, various unplugging and plugging battery, charger etc. nothing has worked. Seems to have started after latest Windows 10 update and not limited to Dell laptops. Microsoft says its a hardware issue, Dell says buy a newer laptop!
Does anyone have some insight on this?

The model and age is not shared.

So I can't check into much of anything. Here I update the BIOS, check to see if the motherboard chipset drivers are those recommended by Dell and then test with a new charger and battery. Dell uses a third wire and when that fails you get this message. If you believe it to be Microsoft's Windows then you load up the OS that works and never change.

And the battery is usually the original.

The usual story is the battery or charger is long gone. I find half the time the owner won't put in a new battery.

A laptop battery can wear out in one year.

These are only 300 cycle rated (99% of laptops I look at) so past 2 years and you find a lot of iffy to dead batteries.

Replaced battery, registers 85% but still says plugged in not charging. Rechecked bios and all drivers are current and reloaded just to be sure. Still looking for answer.

The other issues.

Dell uses a third wire to talk between charger and motherboard. This was in response to battery fires. That wire or connection is known to break. Dell also may have firmware updates. And then you have motherboard failures. NO DRIVERS ARE REQUIRED if I power down and want to charge. Some new techs forget this test. If you can't get it to charge while it's off, the problem is in the parts that deal with charging. Motherboard, charger, battery and connections.

It's an all too common failure area. Some want it to be a driver (cheap) but that's only about 10% of the encounters I've worked on.

Just to recap, clone chargers (non-Dell) and batteries can cause this. And what do most people buy? (Not dell issued parts.)

Solved it. Bought a new 90w charger ($20) and it now charges. Seems strange that previous 65w charged (supplied by Dell) would stop charging even though it ran the computer and had charged battery before. So something changed but what? Power supply circuitry? Guess I can try testing the old power supply, but anyway it’s now apparently working as should! Was 65w too small?

Wonder if the third/signal wire in the power supply was bad. I have read it is necessary for battery charging but not to run the laptop.

Just to recap.

The third wire breaks or becomes unreliable. There are thousands of posts about this on the web.

To test the old supply would take an engineer, oscilloscope and more. Most folk are satisfying with old is broek and new is working.
