Having problems with your Toshiba Satellite Pro L300 Notebook ?

No power from ac adaptor

\015 I noticed that my ac adaptor was not charging. I checked the power at the wall outlet and discovered it was at 144 VAC, 60hz. Even when plugged into a different outlet with 126 VAC the adaptor still has no output power. Is there an internal overload which may automatically reset or maybe a fuse?\015

Answers :

No, there are no reset button or fuse in these laptop adapters, they are a sealed unit. The lead/plug maybe broken at the plug. Test the voltage at the plug with a multi-meter, the output voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

\015\012If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
\015\012This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. I suggest you get a quote first.
