Laptop power leads

[BBx]

Hello everyone

Bit of a noob question, my laptop died the other day (the battery has had it so unless it is plugged into power it will not turn on).

Thought I had lost it for good as it wouldn't turn on or charge when it was plugged in, so I asked Rob to get his power lead to try.

And it works.

His is an Acer Inspire and mine an Acer Extensa - I can only see Aspire power leads for sale online.

My question is, if I get one that is supposed to be for the Aspire do you think it will be ok? :/ They are both 3 pronged leads with transformery things in the middle.

Thanks
