I have a Toshiba laptop that charges while it is off - it charges normally, the battery LED shows orange (charging) as per normal.
However when the charger is plugged in and laptop is on, the power led is off, it doesnt charge. it says "Plugged in, not charging" and battery LED blinks continuously in its orange color.
If the laptop is out of battery and charger is on the power led is on with yellow color (normal).
Any suggestions would be appreciated.
