Aspire A515-51G, still not charging even after battery replacement

Hi,

I previously asked the question about not charging while running: https://community.acer.com/en/discussion/comment/1089271 and the answer (Thanks JackE!  :) ) seemed to work. But now the laptop is back to not charging even when turned off. When plugging the charger, orange light comes up for a few minutes, but then the blinking with both the blue and orange light begins, and the computer is not charged even after charging overnight.

I have swapped the battery (battery report seemed to be 100%), reset the battery with the clip, still nothing. Any suggestions on what else to try? The charging issues make the OS to throttle very aggressively, to the point that this laptop (2018 i5 with dedicated nvidia gpu) is performing worse than a 2016 i5 with intel integrated graphics when playing SC2 (with min detail config, a game from 2010! Should be minimal effort for it). 

Thanks!

    >>>battery report seemed to be 100%>>>

    The current 100% full charge energy capacity in Whr vs the original 100% full charge energy design capacity in Whr is the figure of merit.

    So go to the elevated command prompt.  Enter 'powercfg /batteryreport'. Then return to the desktop. Open file explorer. Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser. Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.

    Battery is fresh and looks like it:

    Design capacity: 48944 mWh
    Full charge capacity: 52440 mWh

    Nope. Charge controller is messed up. Open Device Manager. Click batteries folder. Right click and uninstall ALL drivers you find in this folder. Don't try to re-install anything. Shut down Windows normally. Turn it back on. Then do the battery report again. The full charge capacity must be equal to or less than the design capacity, NOT more.

    Removed all devices from the Batteries folder, rebooted, ran the report again. Same results:

    Do you still have an old battery to repeat the battery report? This should give us a clue as to whether the internal battery charge regulator or mainboard charge regulator is faulty.

    I think when people get their laptops new, the Full Charge Capacity will be higher than Designed Capacity somewhat.

    Had my Acer laptop for seven months now and the Fully Charge Capacity is still higher than Designed Capacity, but not as much as when it was new.

    Don't necessarily disagree. Except when the laptop is still not charging even after battery replacement and displays blinking charge LEDs. This suggests to me, something ain't right with the charge controllers either inside the battery or on the mainboard. :)

    I could do that. I have an older report from just before replacing the battery that says Full Charge 38426 mWh (and the same design capacity), does that work, or would it be better to replace the battery again and re-run? (I think I still have the older battery)

    >>> better to replace the battery again and re-run? >>>

    Absolutely. If the old battery still shows the same existing full 100% capacity as the original full 100% design capacity, then it's more likely a mainboard problem than a battery problem.

    Sorry, my previous reply wasn't clear. The old report shows Full Charge 38426 mWh and design capacity 48944 mWh (the same design capacity as the new battery report is what I meant).

    Please re-do the report with old battery anyway. The blinking LEDs  are abnormal. If we can rule out or rule in the battery packs and the charge control software as the cause, then we'll have a better idea if the mainboard's charge control hardware is involved. Because it's looking more like a full erase everything ALT+F10 cold boot factory reset is about the best way to rule in or rule out a mainboard hardware.  If you're ready to do a reset now, then forget about re-doing the battery report

    Thank you for your response. I'll back up, try the factory reset, and report back.

    OK. Hope it does the trick for you. :)

    or the power supply is faulty. Mine read about 21vdc open circuit.

    On a whim, before actually going scorched earth on the windows install, I booted a Linux live USB stick, and then engaged a stress test and a graphics benchmark at the same time. All 8 CPUs at 100%, but all lights stayed blue and the charge never went under 100% (as it should be!).

    So I guess this strongly suggests Win10 is to blame. If I had to bet, I'd blame the hybrid Intel/Nvidia setup not playing quite nice with each other (after years of updates of both the Intel and Nvidia drivers separately)and messing with power management. I guess I'm going to try uninstall and reinstall all graphics drivers, and if that doesn't work then a full Windows reinstall should fix it.

    And one more data point: I tried to run the same benchmark on windows. With the Nvidia controller it stopped charging (blinking orange light) almost immediately. I then disabled the Nvidia gpu in device manager and ran the same benchmark. It performs... as well as your expect an Intel graphics adapter to perform on a benchmark, BUT power keeps flowing *into* the battery (battery % actually goes up while the benchmark is running). 

    When running a "heavy" StarCraft II game (big map with 7 AIs to make sure there's a big amount of units to keep track of) it does show the same symptom (not charging, flashing orange light) but it seemed to me SC2 actually performed *better* than when using the nVidia card.

    Good guess. Win10 ain't anything like what it used to be. What it used to be should still on your hidden factory reset partition. If this partition is still intact, the ALT+F10 cold boot method will bring it back to a factory fresh state. The years of updates should only take only an hour or two to complete after such a factory reset. And if you make sure SystemProtection is turned on in ControlPanel's restore point app, you'll probably be able to identify which errant update is causing the problem and temporarily block it from re-installing.

    I have the same problem but with acer predator helios 300 when I try to play any game using graphic card the orange and blue light start blinking and not charge while pluged in and battery drain very fast .

  • JackE

    This is normal under heavy power load when the battery must help the charger meet the load. During those times the battery is discharging even though plugged in. When battery drops below about 50% charge level, performance will drop because battery charging will take precedent over game playing. Time to stop game playing and allow battery to charge back up to 100%.

    Bro same problem is with me of blinking of light on playing a heavy software what should I do
