Acer Aspire 5100 Charger Fault?

Question

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.

Answer 1

If the cylinder is about 1/2 inch thick and about 1 inch long (along the wire), it's an interference filter.  The computer will work without it, but might not meet government interference specs.  (I'm sure you're terribly worried about that, right?)

The problem is getting the wires connected correctly - if you reverse them, you'll need a new laptop.  Be careful, "measure twice, cut once" kind of thing.  Find someone with a meter and determine the polarity - most likely, the center is positive.  Make sure it still is after you finish your repair.  Lots of good electrical tape, starting about an inch before the break.  Heat-shrink tape or tubing on top of that if you can (put it on before you put the connector on if it's tubing).  Tubing (small, very small) on each wire as it goes into the connector - only about 1/8 inch of wire should stick out of each tube.

If you're careful, and you know how to solder in tight places, you can do it.

Answer 2

i would not chance damaging my laptop for the price of a charger ==if it were in my hands  the answer would be different because of equiptment and background ===the round thing could house an electronic component or just be a wire seperator however polarity is most important   if you decide to do it yourself also make splices at least 3 inches away from each other to prevent accidental shorting i would soder and use heat shrink tubing on splices
