Acer e5 576G 50EN battery issue

rgndrck · April 2019

Hi I have an e5 576G 50EN unit. After the either March 2019 or April 2019 windows 1803 update, my laptop's battery started to decrease charge capacity (Charging only up to 83% max now) and the wear level is now more than 50% (in less than a month). I have tried doing the suggested battery reset method (using the pin hole) as well as uninstalling the Microsoft ACPI Compliant Control Method Battery but to no avail. What should I do?

In this case, you should try to calibrate the battery, see: https://www.howtogeek.com/172271/how-to-calibrate-your-laptops-battery-for-accurate-battery-life-estimates/

Look, after the update, my battery's full charge capacity went down from about 35k to just 19k mWh (and still going lesser and lesser). Do you think calibration would fix this or my battery is dying?

Calibration will cause the correct percentage of battery wear to be displayed!

Okay, I would try that. But how can I charge my unit to 100% for calibration when it stops charging before reaching 100%. I have tried suggested methods in the web but still it does not reach 100%. Thank you very much!

Do this:

a) unplug the notebook from the electrical outlet, and then turn off the notebook;

b) let the battery charge up to 100% with the notebook off;

c) When the battery has charged, turn on the notebook using the battery only, then go to the power options and set the notebook to turn off the screen and the hard disk. Program the notebook to turn off when the battery is 4% and then let some video play on youtube until the notebook turns off;

d) When the notebook is off, wait two hours until you recharge the battery with the notebook still turned off!

Hi, still my laptop is not reaching 100% charge. What should I do now? Thank you

Try uninstalling these drivers:

Then check that this button is pressed down by placing some layers of electrical tape:

Try also to update the drivers with the driverbooster or driverpack!

Try also connecting the notebook directly to a properly grounded electrical outlet!

Also check if updating the UEFI (new bios), if it solves the problem!

Hi it's me again, haven't tried updating the bios as you suggested, leaving it as my last resort. As of today, my battery is only at 1% charged though still displaying the "plugged in, charging" message but still the battery is not charging, everytime when AC adapter is removed, my laptop shuts off. Tried using the BatteryInfoView app, it displays zero (0) milliwatts Charge/Discharge Rate, around 14,230 millivolts of voltage level, and 40.8% battery wear level. Please help me resolve the issue. Thank you.

Verify that reinstalling windows by pressing alt + f10 before the Acer logo will solve the problem. You need to back up your files first! Would it be interesting to tell you how long you own the notebook?

rgndrck · May 2019

Hi my battery is now at 0% (plugged in, charging) but never gained a charge. is this already a hardware issue? please help me. thank you.

Do you own the battery for how long?

only about 1 and half years

Have you tried disconnecting and then reconnecting the battery to the motherboard?

Never have tried opening the unit to remove the internal battery. Just tried pressing the button in the battery hole but still does not fix the issue.

Have you tried restoring the notebook to a point before the problem?

there were no restore points available so I tried reinstalling windows through "Fresh Start" sadly, didn't resolve the issue

Have you tried reinstalling windows by pressing alt + f10 before the Acer logo?

I have not tried that one yet. Is that resetting to factory defaults? I will backup my files first then I'll update you once again after doing that method. But for now, can you suggest other ways? I cannot just reset my windows again because I'm currently working on important files. Thanks for the help!

Commodore_1995# · May 2019

Yes, this will reset the notebook to factory defaults!

rgndrck · May 2019

Few more questions regarding the factory reset,

(1) will I lose my windows 10 product ID once I reset my laptop to factory settings?
(2) will the bios be restored also to the factory default version?
(3) do I have to install manually the drivers after performing factory reset or they will come as preinstalled drivers with the factory version of the installed windows?

Thanks a lot.
