Replacing a Power cord.

Toshiba satellite a105 s2... / Psaaku-00906

Specs: N/A
My sister and her husband have a faulty power cord on their laptop. When they plug it in the charge light won't turn on. They borrowed a cord from a friend who has the exact same laptop and it worked fine.

It is a toshiba satellite a105 s2236 model psaaku-00906 and the powercord says "dc19v 3.42a"

They got a spare cord from a friend that says "HP 19v 3.16a" Might that work? Would it be safe to try? (would we have to worry about it frying their system or anything?)

If the voltage amd amp match, would any powercord work?

Otherwise, what methods are there to determine what cord will work on X laptop, without purchasing it and trying it first?

Is there a way to fix a broken laptop power cord?

I am no expert on laptop AC adapters. That said, I have read that some have the opposite polarity on the actually connector that plugs into the laptop. If that were the case it would damage the laptop. I don't know if the above is factual or not but thought I should put it out there anyway.

When in doubt always order batteries, adapters & power cords for Toshiba laptops from no one other than Toshiba themselves at the link below.

Your power cord is 19v 3.32A. The one your borrowed is 19v 3.16A.

It might work but you are going to run out of Amps. That will casue the power supply to over heat and possibly burn out. I wouldn't risk it.

It would be fine if it was the other way round as you can never have to many amps in the power supply, but to few will cause problems.

The voltage, polarity (+/-) and plug dimensions need to match. The amps is a maximum rating and not necessarily what it pulled by the charging circuitry but obviously you want the replacement to be close to the original.
