Laptop will not stay powered after replacing dc jack

\015 Where on the motherboard can i check for power after the dc jack? what reading should i get with the ac adaptor plugged in, im receiving 19v thru the jack on both sides of the motherboard but don't know if it's going any farther. thanks\015

Answers :

Dear friend,
\015\012You must have some knowledge atleast about the various kinds of power supplys used in different electronic appliences. Otherwise you can't move further. The power supply generally goes to various ICcs and switching devices in the motherbord for differnt purposes. It varies from manufacturer to manufacturer; model to model and so on. What about your status in electronics? The output voltage of the adapters - and thus which in the motherboards- varies form company to company and model to model. You can veiw it on the adapter as ' OUTPUT:19V, 4.74A' and like this. It will be the reading that you must get with the adapter. If you don't get this voltage -without plugging it in the AC outlet- the adapter is faulty. If you don't get the voltage mentioned in the adapter on the motherboard- if the adapter is good- then it is somthing wrong on the motherboard.Reply if you need further assistance.
