Must disconnect and reconnect battery to power on Acer laptop

How to avoid having to Power Reset a battery
As it turns out, the previous solution only improved my situation. My laptop will now power on without a power reset.
But if I leave it off overnight, I have to remove the battery and then put it back in in order to power on.
It will also power on using A/C without a power reset and without removing the battery.
I am thinking that this is a driver related issue. I uninstalled and reinstalled the two battery drivers and that resulted in my current situation. I have purchased two new batteries and they both behave the same.
Can someone help me determine how to check battery and driver compatibility?

I recently purchased a replacement battery for my Acer Aspire E5 471G laptop. After experiencing power on problems I found that the original battery when I purchased the laptop was labeled AL14A32 6-cell 2500 mAh Li-ion. The replacement battery is labeled Replacement AL14A32 11.1V 5200 mAh Li-ion.
The problem is that I must remove and then insert the battery in order to power on the laptop.
I am wondering if the difference in batteries can cause this problem. And, would there be a different battery driver (Windows 10) for the replacement. If so, where can I find it.

I see there are a lot of models that start with E5 471G. Are you sure you bought the correct battery?

I have an Acer Aspire One 722. I had to know the exact model because there are lots of AO 722 models. What works for one 722 will not work for a different model. I read lots of posts and looked at lots of sites before I was able to find the correct battery.

I was able to go to a US chain called Battery + Bulbs and get a battery from them that was specifically for my 722 - BZ454. It is guaranteed for a year with a free replacement if it fails. I had to use the guarantee because the first battery refused to charge after 3 weeks. They determined the battery was bad and ordered a replacement. This one has been working fine since April 2017.

I checked out Battery + Bulbs. They had only one battery for the E series Acer and it would not fit my laptop. My laptop is an E5-471G-56YK. The sites that I have checked only show the E5-471G. They don't show any further model breakdown. The manufacturers site describes the original battery as 6 cell. It does not show voltage. I know that there are 14.8V and 11.1V batteries for my laptop but I don't know if that makes a difference when powering on the laptop. Any help would be appreciated.

Still working the problem. It is getting better. I learned from the Acer website that replacement batteries must be "conditioned". They recommend a full discharge and recharge 3 times. I only have to remove and insert the battery now if the laptop is turned off over night as opposed to being turned off only 15 minutes. Waiting over night is taking a lot of time to determine whether the problem is solved. I will update again when the battery is fully "conditioned". The problem however is getting better.

New Information

On a full battery charge I can use the laptop normally for about 10 hours. It powers up, I use it for a while and then turn it off. I can do this over and over for about 10 hours with no problems. After 10 hours if the laptop is off, I must remove the battery and insert it for it to turn on and off again.

Also, when I fully charge the battery and I leave it on A/C power with the battery in and the laptop turned off, the power shuts off (LED goes off) after about 4 hours and I have to remove/insert the battery again. As long as the laptop is on, the power does not fail. If the battery is out and the A/C remains connected the power does not fail. The A/C LED is off.

Has anyone heard of anything like this? I've struggled with this improving situation for about 2 months. I really need some help.

If I may chime in while plodr is offline.

While not the answer and only applies when using the notebook near a regular wall socket/power outlet, once your battery is fully charged either the AC adaptor should be disconnected or the notebook powered down and the battery physically removed and stored somewhere safe, this is to help with prolonging the lifespan of the battery, if you continually keep both the AC adaptor and battery powered up the batteries memory chip will expect to charged to 100% all of the time and will start throwing misreadings when the AC adaptor is disconnected, this only applies to basic notebooks and high end gaming notebooks are different, where possible they should always be run from the mains as the GPU requires the additional power.

Question, was your notebook upgraded from Windows 8.1 to 10.

The laptop was purchased with Windows 8.1 but I did a clean install of 10. Since then all scheduled updates have installed successfully. The problem started when the originally battery stopped charging and I replaced it with the recommended replacement battery.

When you clean installed Windows 10 did you then install the Windows 10 drivers for the notebook and starting with the chipset drivers first.

I did not install a chipset driver after the clean install. I did the clean install about 2 years ago. But I did not reinstall any drivers. Windows 10 and my laptop just worked after the install. Subsequently all updates pushed out by MS have been installed without problems. I had no problem with the power on function until about 6 months ago when I replaced the battery. I believe that I have the correct replacement battery but I am not sure what the voltage of the OEM battery was. The problem improve over time. The original problem was that I had to perform a "power reset" each time I turned on the laptop. Now I only have to remove and insert the battery.

Right now...... no matter what I do, if the laptop remains off for 4 hours or more I have to remove/insert the battery, then it works fine.
After being off for 4 hours the A/C adapter will not power on the laptop with the battery removed and the power LED does not light. With the battery, in the power LED does light.
If less than 4 hours turned off the battery and/or the A/C adapter will turn on the laptop and the power LED does turn on.
If I leave the A/C connected and the battery in, with the laptop turned off sometimes the laptop turns on normally and sometimes the power dies and I have to remove/insert the battery to turn it on.

Could this be a chipset driver issue?

Most unlikely and especially if things were fine running Windows 10 up until the previous battery died.

Best guess is that the problem is with a build up of charge in the MB and predominantly in the capacitors, not an uncommon problem but it usually involves removing the battery, pressing the power on button for 20 seconds or so to get rid of the residual charge in the caps then replacing the battery and the notebook then being able to power up.

Question, does the notebook run hot when in use.

Click to expand...

No, the notebook does not run hot. If I power in on and then immediately turn it off without running any programs I still have the same problem.
At first I did have to get rid of the residual charge as you described, but now I do not. I disconnect the battery reconnect it immediately and the laptop is fine. Can you tell me how to identify a bad capacitor?
This problem has plagued me for months now and no one ( Acer support, local technician or multiple forums) seem to have heard of this problem.
