Hello, 

Since last Friday I have started having an issue with my laptop predator PH317-51. When charging and reaching 90% it suddenly disconnects for 5 seconds or 10s and then reconnects. Now it happens at 80% and I have caught an unusual behavior. Sometimes, when the battery is almost done and I'm reconnecting the charger, it shuts down. Last time it only locked it, it did turn off but did not shut down. I have tried aaall solutions I could find on the internet. Reset the internal battery, turned it on after 2 hours. I thought it was good until it reached 92% and it disconnected. Changed the battery plan on saving battery. When I connected the charger after, it went till 86%, still connected, it dropped to 85% just as soon as it went up to 86% and just 2 or 3 seconds later it was 86%. I spoke to someone in pc service, and they said it might be the motherboard and it usually cannot be fixed in service. I find this a huge hit to my plans and pockets. This laptop wasn't cheap and I'm using it for hard-processed apps for my work and in my hurry to fix it and have it work as before, I opened it to disconnect the battery as some tips on other Acer forums cases were stating, cause I thought the warranty was gone. Usually, things get broken and malfunctioning after the warranty expires. But I still have 3 months left. Now I'm having trust issues. I did not break any sigils, so the inside is untouched and not visible that it was opened. but it can be seen slightly on the edge of the case where it was a bit forced to open. I wonder if they would still accept it.... nevertheless, my last run with the official laptop service on a previous Acer laptop (normal one) left me with a bitter taste. Some of the components that were good quality and could be removed, were changed. Well, this would be another story. Now I don't know what to do. Everything worked normally, I had just disconnected it from the power to go to another room and when reconnected it, it just started doing this. No other signs were displaying the possibility of this issue appearing and the report when running the battery report shows issues just starting the 20th of March. The power efficiency shows quite some worrying errors. I've attached the files, if they are of any help.

Can someone give me some advice on this? I'm terribly afraid that if it is the motherboard... soon enough it will break down... though it works normally with no issues and I can do my daily work as long as it is not in 80% or does not require charging.. I still want to have it repaired.

Thank you in advance,
