Is this probably a faulty battery, and should I consider replacing it?
Is this probably a faulty battery, and should I consider replacing it?
Hi there.
I have an Asus VivoBook X712JA laptop. It seems to be around 4 or 5 years old and still works for my needs, but recently it stopped charging because the OEM charger was dead. I bought a cheap 45W charger from Amazon, which failed too. Now I’m using a 65W charger, but the battery only charges up to 60%, and I only plug it in when the laptop is off to avoid more damage. I think the battery is probably bad—partially so. My choice is to replace the battery for about $50 or get a new laptop. I’m leaning toward replacing it, but I’d like to hear from others if they think it’s worth repairing versus buying a new one. Please let me know your thoughts.
Welcome to the forums, newcomer!
I now have the laptop running with a 65w charger.
What did you get after the 45W adapter incident?
When buying replacement parts, always choose genuine replacements that match the original model. It seems you might have damaged the charging circuitry inside the laptop's motherboard.
You should probably take it to a certified laptop repair shop for that area.
Remember, replace the battery with an authentic part.

Thank you for the response. The first charger that stopped working was the original ASUS one, which was swapped out for an aftermarket 45W model that failed right away. Now the 65W aftermarket charger is functioning but the battery only charges up to 60%. Since the battery uses three cells, it’s possible the battery itself is deteriorating. I wouldn’t take it to a repair shop considering how old the laptop is, but I might go ahead and buy a replacement battery for about $50. Appreciate your help.
if the battery is deteriorating, replace it promptly since it might be breaking down chemically and could expand. it's also possible that the charging unit sent an excess voltage to the BMS, which may have damaged the battery. a faulty BMS can cause overheating and explosions. the fact that it cannot exceed 60 volts indicates the BMS is trying to protect the battery from explosion. i would be very careful about keeping it connected to the charger for extended times.
