The charging process on my Folio 9470m doesn't "kick in" unless I turn it off, remove/replace bat.

[UncleScotty]

I went back and installed the Intel (ME) firmware, then did the Battery control thingy removal (I have two of them....see below.....so uninstalled BOTH of them.....but when I get to Step 4, "Press and hold power button for 30 seconds"......the computer starts back up....every time.....and runs on battery power.

Why wouldn't it? (And when I go look in the Device Manager, the Compliant Control Method Battery items are back/restored.

What should I do now? Let it charge up and see if I can recreate my non-charging scenario? (by running it on battery until it is down to below 30 or 40% and see if I can get it to charge by plugging it back in?)

[UncleScotty]

I never could get the computer to NOT start up when I pushed and held the power button for 30 seconds.....but it looks like you may have solved my problem.

I pulled the power cord and ran the battery down to 55%, then when I plugged the charger back in, it proceeded to charge the battery.

I've pulled the charger out again and will let the computer just sit until it dies, then plug it in in the morning and see what happens.

Will respond with results over coffee tomorrow.

Thanks for all your patience! Good night.

I don't know exactly which update(s) or procedure(s) did the trick, but when I plugged in my totally discharged computer this morning, it immediately showed that it was charging. THANK YOU!!

Here's the HP Support Assistant information you asked for.

Thanks again for your patience and all your responses.

Is there somewhere I can give you "kudos"?

Hello @UncleScotty 

The pleasure is mine !

Kind regards

[UncleScotty]

Hmmmmmm. Looks like I might have celebrated a little bit prematurely.

After about two weeks of charging satisfactorily, (albeit, not being run on battery all that often), my laptop was left unplugged after being used on the battery for a couple of hours in the kitchen.

When I plugged it in the next morning, I noticed the battery was reading only a 5% charge and it wouldn't start (and hasn't started for two days now) charging.

Is it possible that if the computer is left to "die" while under battery power, that that does something critical to the charging circuitry that prevents it from activating again?
I went to the Device Manager and removed the ACPI Compliant Control Method Battery driver(s), Restarted the computer, but it still didn't begin to charge.

Wondering, 1) Do I have to avoid discharging the battery completely?.....and/or 2) is there something in particular I have to perform if/when I DO run the battery down to "nothing" in order to ensure that it WILL charge again when reconnected?

Thanks for any additional info. Sorry to be a nuisance!

Hello @UncleScotty 

(1) Remove battery to be able to start notebook

(2) Disable Windows Shutdown Sleep and Hibernate

How to disable Sleep Mode or Hibernation

(3) Shutdown notebook

(4) Disconnect charger

(5) Press and hold <power> button for 30 seconds

(6) Connect battery and charger !

(7) Test your notebook

(8) Please report back

I don't mean to sound ungrateful, but I don't know that performing the procedure you just recommended is going to "prove" or solve anything.

Why? Because your Step one.....removing the battery....is what always cures the problem.

But I don't want to have to remove the battery every time the charging process fails to activate.

(Unless your plan is to have me charge the battery up to, say, 30%, then remove the charger and run on battery power until the battery is down to 5% again.....and/or the computer shuts down...... THEN try plugging in the charger to see what happens.

(Also, not sure what you mean in Item #7...."Test your notebook". Do you mean: just verify if it is now charging? Or was there some other "test" I should perform?
Regardless, I just now completed your instructions....and, as expected, it is now charging...as it always does after I remove and replace the battery.)

What I will do now, is wait until the battery gets up to 20%, then I'll remove the charger and use the computer until the battery dies and the notebook shuts down. Then I'll plug the charger back in and see if the computer AND its charging circuitry BOTH begin to work.

I'll get back to you after I've done this, thanks.

I left my charger connected until the battery indicated 16% charged.

Then I unplugged the charger and continued using the laptop until it died (about 25 minutes)

When I plugged it back in (5 minutes ago), the battery began charging immediately and it is already showing 10%.

Question: Do I have to leave my Sleep and Hibernation settings at Never in order for things to continue "behaving"?

Thanks!

The <Hibernate> mode does not discharge the battery when the AC adapter is unplugged, but the <Sleep> mode does! So at least disable the <Sleep> mode.

[UncleScotty]

Yes, thanks. I understand that.

But, is the activation or de-activation of either of these power settings the cause of my charging process not working when I plug the charger back in after the laptop has been working on battery power for a few hours?

I'm not at all concerned with my battery being discharged. What I AM concerned about is that it DOESN'T charge when I plug the charger back into the PC after it's been using only battery power.

It seems that REMOVING and RE-INSTALLING the battery is the only way to "remind" the charging circuitry/drivers/whatever, that they are NOW supposed to be working.

Thanks.
