New battery received, PC is back to normal, charging immediately.

 

The conclusion is that we have an interlock of two bugs, both of a similar nature:

1. Charging: charging should measure every cell, not just the first or an average (I don't know which without reverse-engineering the code, which wouldn't be a friendly act), which can indicate no charging's needed.

2. Usage: the same again, measure every cell before deciding the battery's flat.

 

Can you pass this one back to MS ACPI support, please, Sparkles, as it's a fairly serious bug.

 

An improvement to the HP Battery Health Centre support program would be to allow every cell to be drained individually, if you can pass that through to the wish-list too.

 

Many thanks

 My computer is an HP Sleek Book Pavilion.  I had the same problem however I found the left battery lock was not in the lock position once I slide it into lock it started to charge.

my laptop is charging when it is off. but when it is on it shows that "plugged in, not charging".
I tried suggested battery removal, uninstall battery driver in device manager, then power off, then power on. but not getting any solution. still showing that message

Sounds like you'll have to change the battery, then. If it's a couple of years old, one of the cells in it might have died - the rest give an indication the thing's fine. Inexperienced MS prgramming is at root - they look on the battery as a single cell.

Sorry, Leo, I have to correct you because you're only partly right.

 

We have discovered a number of different problems, and only have a part heirarchy of solutions so far.

 

As you say, one of the first things to try is indeed your solution. I tried that, but it didn't solve the problem.

 

The next thing i did was get a new battery, and that fixed it.

 

The outstanding need to be addressed is what caused it. The physical reality is that the battery contains four cells, and the failure of any one of them could stop the battery working, if they were wired in series. However, I don't think HP do that, as they can certainly monitor the charge in each. What's happening is that one piece of software is monitoring the maximum charge on the fourr, and another the minimum, so the latter says "this battery needs charging" and the former says "it's fully charged" which is indeed the case, cell by cell: one had failed, the other was full, but the PC used the former and wouldn't start. It's just poor programming, mostly because they should have gone for a battery "driver" designed by the maker to handle it for them. And that is what isn't being addressed, at least in Windows 8

Yes!!! this was totally the problem. I have a 6 mo. old HP 350 and was getting the "plugged in, not charging" message, stuck @ 15%.  Read this reply, checked the adapter plug, and BAM! bent center pin. Straightened it out (yes with good light tweezers and magnifying glass.) Now @ 40%, "plugged in,charging."

  

   I was surprised to find this, as I try to be very carefull with the AC plug (was the downfall of my wife's old laptop, dragging the power brick around the house, thus ripping the plug off the MOBO.

 

  Quality of plug/center pin seems low. This tiny pin must be the "feedback connection" of the charging system, your plug might be different, but pay attention to all the connections on your charging plug
