This happened to me with my last laptop. I took it in and they told me that the piece inside that the cord plugs into came loose and they would have to go in, take the whole thing apart and resauter (spelling?) the piece which was pretty costly. Hence, I'm looking for a new one. Hope that helps.
My laptop just suddenly doesn't like the battery and stop charging it!. I do not know what has happened.
It is VPR Matrix 110 200A5. Power port, A/C adapter (19V - 4.74A) are still in good condition. Laptop has not been overheated. The battery is still good (checked with other laptop).
Does anyone have same experience? please give me a hint how to solve it without replacing the motherboard. I tried to search on google but didn't work out.
