---- It takes me more than an hour to simply disassemble/reassemble
any of my laptops to the point of getting to the power jack before I
can even assess the problem, and I have done this about a dozen times
on many different Toshiba models. You must be the world's fastest
laptop repair man or have as many arms as the Hindu god Shiva. I
do suspect your solder repair of the center pole of the power
connector will fail eventually if you continue to use that laptop as
a portable device. Solder joints are subject to cracking under
movement & distraction, and the 3+ amps going through the power jack
at max load causes heat to build up, loosening both solder & epoxy
joints over time. "Stronger than the original" isn't saying
much. The "original" is a defect waiting to happen, power jacks of
most laptops are just not designed for frequent re-connections or for
the stress of using laptops as portable devices. An improvement on
the original involves substituting the conventional power jack with
something better engineered to take portable stress, which Lenovo or
Apple have done. The Apple power connector is the best in the
business. ---- Epoxy putty is much better than the more liquid forms
of epoxy glue, for repairing small cracked plastic & metal housings
of all kinds. It is extremely thick when mixed and stays where it is
applied, no matter what the position. It is more of a space-filler
or structural element than a glue. Once set, it can be easily drilled
or trimmed with a knife or something like a Dremel tool. Buy it at
WalMart, etc. --- For a comprehensive review of laptop power jack

I have been buying laptops since 1984 with the Epson PX-8. And I have to
admit that the 80's and 90's the jack was more solid as it has added support
from the outside of the case. Today they are solely supported by the
motherboard alone. Not as good I know. But don't bang it, don't twist it, or
do anything else... every single jack I know will last much longer than you
will when treated correctly. I have never had a single jack fail on me yet.
Although I have bought used laptops that the jack was abused. So I don't
have a lot of sympathy for those who had a jack that has failed.

It's a P/Bell Notebook E series I bought off eBay for a couple of
tasks for my work. The socket is under the internal battery cover.
Soldering was tricky as the snapped joint was barely proud of the MB.
The epoxy was applied with a toothpick so I could get it in the nooks
& cranies - taking care not to apply too much and let it run into the
socket (plug in situ to ensure correct alignmant of the centre pole).
There were a couple of generous gaps between the socket o/dia and the
socket MB housing into which went a reasonable amount of epoxy. By
supporting the laptop at various angles the flow and position could be
controlled before it set (now 5 applications). I agree the original
design is poor, but the amount of epoxy holding it together now and
the feel of the repair I suspect it'll last a good while yet. The
seller left the original receipts in the bag, one shows the MB had
been replaced due to this fault before. If it goes tits up again I'll
solder a flying lead and make the connection externally.
