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?

Hello

hopefully some of our members will chime in soon.

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.

no driver needed for batteries.
the laptop may have software to control battery performance and longevity but that’s just eye-candy.
just plug in the battery and it’ll either work or not.
2500mAH versus 5200mAH just means the new battery will have (approx) twice has much capacity.
I assume the original one was also 11.1 volts?

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.

Do you have the original battery?
If it doesn’t have the information on it, it might have a manufacturer’s model number. You can start searching using that number.

Here is a Malaysian site Search, Compare, Shop and Buy at Best Prices |Priceza.com.my
not sure if the alpha-numeric string in parentheses is the manufacturer’s number.

I found a Canadian site that gives this: AL14A32 KT.00603.008

Searching for that
https://www.newegg.com/Product/Produ...16J-0027-00096
BUT it only says 471G so I’m not sure it works for the exact model 471G-56YK.

I hope you can find the model number on the original battery.

I suspect the voltage does matter.

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.
