Must disconnect and reconnect battery to power on Acer laptop

[jrobb]

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?

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.

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.

Examples of good and bad caps + some good info here

It is a rather odd issue that you are having for sure, before opening up the notebook to inspect the caps I would do the most basic of cleans with canned compressed air first and with the RAM removed from the slot/s, example cleaning guide here

Thanks Phillpower2, I’m going to try that and post the results. I’m at a point that I have to try everything.

[phillpower2]

You are welcome jrobb.

Going offline shortly as I have an early start but will check back tomorrow, good luck meanwhile.

[phillpower2]

Any update jrobb?

[phillpower2]

. I am stumped.

Got to admit - so am I

The situation that you are in with the notebook would not bother me as I only run the notebook on battery every couple of weeks, run it out of charge, recharge it then store it in the filing cabinet until the next exercise, same battery from new seven years ago

Thanks for the support Phillpower2. I use my laptop the same way that you do. The problem is that it will not turn on with only the A/C power connected. The battery must be in. So each time I turn it on, I must disconnect the HDMI, Ethernet and Adapter, turn it over remove the battery and reinsert it. It’s a big hassle. Keep your ears to the ground. If you hear anything let me know. Thanks again.

[phillpower2]

If you hear anything let me know.

Will do (y)

So each time I turn it on, I must disconnect the HDMI, Ethernet and Adapter,

Curious, do you have to remove the battery even when the HDMI, Ethernet and adaptor have not been connected.

You are welcome btw

Yeah. If the laptop is off for about 4 hours or more, I have to remove the battery no matter what, in order to turn it on. I can run it on A/C without the battery, no problem. If I turn it off for less than 4 hours, I can turn it off and on all day with A/C only. But if I turn it off for more than 4 hours, I must insert the battery A/C power or not. Go figure.

[phillpower2]

Real odd

Any updates for us?
