So I own a Samsung RV520 for 2 years now and 3 months ago my AC adapter stopped working and had to replaced. I went to the closest computer service and they gave me an universal AC adapter. Now, the new AC adapter worked like a charm... for 2 weeks.
It was just an average work day and I plugged in my AC adapter and started working. After 2 hours I smelt something funny I didn't know what it was, I ignored it and went back home.
The next day I smelt it again and I found out that the plug from the adapter was smoking and really hot. I disconnected it and found that the tip (yellow plastic ring) completely melted INSIDE my laptop.
Eversince I plug it in, it would start smoking the very second I connected it. So obviously I need a replacement.
Just found out that my laptop old ac adapter used 60 watt and this one 90 watt, even though the guys at the service said it was fine...
Is there any way to prevent this?
