The cord on the laptop's PSU plug (the small, hollow, cylindrical shape
that plugs into the side of the laptop) is fraying were it enters the
plug. It's possible to manoeuvre the cord to get the laptop to charge
but it's going to fall apart soon.

New PSUs are available from Hong Kong on ebay for a fiver but past
experience of cheap goods from HK hasn't been good and I'm concerned
that the adaptor brick might damage the laptop with, for example, poor
voltage regulation.

Is it possible to repair the plug? If I cut the cable, are spares
available to solder/screw on?

TIA

They come in quite a range of sizes but are pretty easy to find. Maplins
does quite a wide range:

Hmm, Maplin were unable to find anything to match my old IBM laptop and
I'm very doubtful about the plugs used in some Dell models.
With the IBM, I ended up cutting away the moulded outside of the plug
and peeling it all off, then cutting back the cable to beyond the break
and resoldering. Then I think I used hot-melt glue to encapsulate the
repair. It looked awful, but worked.

I asked somewhere, but no-one seemed to know a source for any decent
semi-flexible reasonably cheap encapsulation material.

Self amalgamating tape. Can be built up around the plug and tailed off
with less layers along the cable to give progressive strain relief.

No good if you have a recent, e.g., IBM laptop, nor, I suspect, a
number of other manufacturers. Not everyone uses ordinary "DC"
connectors these days.

How about buying the £5 replacement, and just using the cable off it?

I've usually found that the plugs fail on the cheap ones from China

available to solder/screw on?

I've never found a supplier for the plugs on my Acer laptops (DC power plug
5.5 x 1.7).

Be aware, the ones sold by Maplin usually aren't rated for the sort of
current a laptop can use (although they will work), RS do some high
current ones but they cost a bit more and it's a limited range, not all
sizes are available.

I've also found some very 'odd' things when cheap rip off PSUs are used,
like the battery not charging properly or the laptop refusing to power
on, one hung every time a USB device was plugged in whilst the rip-off
adapter was in use!

The first question asked whenever a client had a charging or other power
related problem was if they had the original PSU.

What laptop is it?

Got a pic of the connector?

I've got a couple of spare PSU's, the cable at least may be of use to
you.

A number of laptops, Dell in particular use what looks like a normal
DC power plug of that type but are in fact three pole connectors, the
third wire used for measuring battery temperature.

As far as I know, and experience of folks who've been through the mill
with trying to use 3rd party supplies, the third wire is there to aid
the laptop in determining if the adaptor is a genuine (and judged safe)
manufacturer approved adaptor. There is an ID chip built into the
adaptor; Battery charging is refused in the laptop if the adaptor hasn't
been recognised (or the third pole connector in the middle of the
connector has fractured).

If battery temperature monitoring has been added, I'd suggest that's a
very recent addition to combat the uproar about restrictive practices on
accessory supply.

Thanks, had thought of that but the cable in question is fixed into the

Thanks, that pretty much confirms my worries about the HK sourced

Just chop it off and join the relevant leads together with solder and
heat-shrink.

If it looks a little odd that's because I used the 'lump' on the cable
to prop the brick up!

I've got a couple of spare PSU's, the cable at least may be of use to

Thanks. I'll open up the plug and get back to you.

OK, that plug is ...

interior diameter: 2.5 mm external diameter: 5.5 mm
and in this application is required to reliably carry 3Amps.

From your picture looks like a long shaft - 14mm do?

Order Code HH63T at Maplin, 99 pence.

Free delivery up to this Tuesday, or your local shop.

- then it's a soldering iron job if up to it...
