Power issue

eagle01987

Hi ,
I have an annoying issue with my laptop Acer Aspire nitro V17 -791g black edition . The battery was showing plugged in charging but it was not actually charging fixed at 61 %. and laptop immediately shutdown once i unplug the power cable .I tried resetting the battery but again same problem also i noticed significant drop in my frame rate and hang during game play . So i thought that this could be battery issue since that most of the times i use the laptop while adapter is plugged in . So i opened the case and i unplugged the battery cable ( it was not working anyway ) and i noticed the gameplay frame rate is ok again and no graphic freeze .
I ordered ne battery same model and changed the battery but now i can see plugged in not charging and battery getting dropped everyday . I can see the amber light blink sometimes and laptop battery status says charging for a second but it goes away ( it is almost like the adapter is trying to charge it but it is unable to do so ) , so i suspected the adapter and i measure it with multi meter and it gives 18 volt ( it should be 19.5 ) , however when i unplug the cable the laptop still immediately lose power and shut down , so i'm not sure is it the laptop internal power circuit or the adapter or sopmething else . Can anybody help please ?!

Blinking amber battery status suggests that both old & new batteries were in a critically low state of charge to begin with. The charger will automatically stop charging when batteries are in this state. If the laptop still runs OK on the charger alone with battery disconnected, the charger is probably OK. I suggest that you turn the machine off. Then reconnect the new battery and try to charge it with the machine turned off. The amber light might blink again and then turn off. But still leave the charger plugged in with the machine turned off for 7 or 8 hours to see if the charger will automatically try to start charging again till the amber light is solid. Jack E/NJ

I actually tried that for a night but still the new battery is not charging and the device can not run on it . is there any internal component inside the laptop that could be causing the problem ( power circuit or something ) ?

Possibly. Sounds like a short in the where the battery connects to the mainboard. But I'd first like to know if the charger still runs the laptop OK with the battery disconnected. Jack E/NJ

yes, the laptop runs fine on the charger alone specially when i disconnect the battery cable inside the laptop , it also runs when the battery cable is connected to the motherboard but with some performance issue while gaming (frame rate drops )

The charger seems like it's overloaded when the batteries are plugged in. So pull the battery plug. Carefully check that all the pins inside the mainboard battery receptacle are straight up with none bent. Use a bright light and magnifying glass to inspect if possible.

If the pins seem to be aligned properly, then reconnect the battery and charger, reboot the system and open Device Manager. Click on Device Manager batteries folder. Uninstall MS ACPI-compliant control method driver. Exit without re-installing and reboot the computer. Report back. Jack E/NJ
