Acer Aspire 5100 Power Cable

[Stanyer]

Hi
I have an acer aspire 5100 laptop, the cable for me is broke, on the end that plugs into the laptop there is a small cyclinder thing where the wire goes into one end and comes out the other onto about 3cm of wire and then onto the adapter that goes into the laptop.
The wire has been dodgy for ages but now its packed in completely, the fault is around part of the wire on one end of the cylinder.
Would it be possible to cut the cylinder out and rewire the 2 ends directly to each other and make it work or does the cylinder have some sort of converter or something in it? Thanks.

no need for it. its just a passive filter

The "cylinder" is nothing more than a ferrite core that is designed to reduce interference on the DC power line, the laptop will quite happily function without it.

For what it's worth, Maplin do (fairly cheap) switched mode universal laptop power supplies (switchable voltage, stabalised current) that fit most laptops without a problem.
