the amp and voltage output of an adapter (or anything for that matter) has got little to nothing todo with the kind of plug. (in most cases). Never think that you have a correct adapter when the plugs match; a plug doesn't say anything (goes in general for those who read this too).

This most likely means your battery is fuxored (by wrong setting of adapter or shortcut by old adapter).

Personally I never ever use so called "universal adapters". In general they are of very low quality, their output fluxuates (this is something you almost never find on such adapters: the stability of them) and they seldom output the exact voltage or amp as you set them to.
There is a good reason why the replacement adapter is expensive!!! (minus the brand you pay for; but still...)
Anyways, all you have to do if the wire was cut, was to replace the wire or part of the wire and it would be perfectly fine. Unless the adapter itself was burned up, but in that case it simply wouldn't work anymore and you've only lost, like, $0.0001 for the wire.
Now you possibly have a very low quality adapter _and_ maybe a fuxored battery.

The newer adaptor runs at a higher current, and has a variable voltage. Both of these can cause problems.
No that's wrong...
The new adapter has a variable current because it has a variable voltage, not a "higher current". The current depends on the voltage. That is also the reason why they print out the maximum power output and not the current output.
If his old adapter has an output of 19V and 3.42A, it means the power consumption is 19 x 3.42 = 64,98W, aka 65W.
If the new adapter is set to 19V, the current will be 65W / 19V = 3.42A... Exactly the same as the old one.
Conclussion: the adapter should be absolutely perfect for the job (if set right, and with the condition that it doesn't fluxuate too much).

correct...
But beware! Do not set the voltage too low either. eg: let's say you set it to 10V, what will the current be? 65 / 10 = 6.5A!!! result: fuse blown... If it has a fuse at all of course. Which is another disadvantage of cheap adapters, they simply melt down or blow up and quite often in the process take the equipment which is hooked to it with it.

Absolutely not true. Plugs have got absolutely nothing todo with voltage settings... If they do, it would be a crappy adapter.

If that would be the case, put that adapter in the bin immediatly as that isn't the correct adapter at all.
If this is the case the 15V-24V does not mean you can select the voltage you want, it means the adpater will output whatever voltage depending on the voltage of your power grid at home. eg: if that is only 100V AC, then the adapter will output 15V DC. If it is 240V AC, then the adpater will output 24V... In which case this would be a crap adapter as an adapter should output a fixed voltage, especially for computers who are extremely sensetive to such things.
Compare this to the text on the old adpater, eventhough it says you can plug it in to a powergrid which gives 100V to 240V AC, it will always output 19V DC!!!!!
A universal variable adapter should _always_ have a voltage selection button. Usually in the form of a small turn button. If it hasn't, it is not an universal variable adapter at all and just a common cheap thing (which they call universal because it has some different sizes of plugs).
It is an universal _variable_ adapter which you need (a good one) or a fixed adapter with the correct output specs 19V==3.42A. The plugs don't matter that much as you can buy and/or find plug converters in all kind of sizes and shapes.
All in all, spend some money on buying an original one (after you tried fixing the wire of the old one; be carefull you don't mix up the + with the - ; it is DC afterall). Quality doesn't come cheap....
