Question about Computers & Internet
This may point to a couple of things. One is the DC adapter and the other may be the power jack or the power board inside. The jack on the laptop can wear loose. You should notice that the power cord is sloppy or moves and that the power led will flicker if this is the case. The power board does fail but it rather uncommon.
The dc power adapter (brick) might the culprit. To check you need to use a voltmeter. It takes a few seconds to check and you would know if it is good or needs replacing. Just trying to think who to suggest you take it to that would have a meter. Battery stores or electronics places should. A computer store with a tech who has a clue will have one. If there get no volts then order a new one in. If you get power at or above what it is supposed to do (printed on the label) then the problem is the power board inside. This is a bit of a pain to hunt ths down but is how you have to check it.
If it is the powerboard you need to get a repair estimate. You don;t have your model etc listed so I can't tell you the price. Some will have the power section built into the main or motherboard others will have a seperate little board. Depending on how new or old it is you may pay $35-$50 for a power board and $125-$300 for a new mainboard plus labour.
A power jack is worth $10-$90 plus labour.
My bet would be on the power brick, followed by the jack. Those are the two very common causes. The power jack on some brands is all I would look at others are a bit better.
