Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

The symptoms you describe are often resultant from

A. a defective AC Adapter - even when plugged in, it will not charge the battery in the laptop, nor allow it to power On, even when it appears to be working, whether owing to a loose connection internally, or a broken wire internally, or some other internal problem.

and

B. a battery in the laptop that is either completely discharged (partly as a result of (A)) or is 'dead' and cannot deliver power to start up the laptop.

I need a new power cord or a new battery?
Expert:  Russell H. replied 4 months ago.

I suspect you need a new AC Adapter.

Unless you yanked hard on the cord that goes into the computer - in which case, the AC adapter would be OK, but the power jack in the computer would need soldering back on. If, when you wiggle the plug in the jack, there is a lot of 'play', that is most likely the case. But I'm just trying to cover all possibilities here.

The way to be certain is, to measure the output from the AC Adapter, that goes into your computer, with a voltmeter, and see if it is still providing the right voltage. If it isn't, it needs replacing.

Do you need a source for such an AC Adapter for your model of Toshiba laptop?
