The power connection on the system board is fried. When a jack starts to
fail, sparking will eventually cause failure of the connection on the board,
and on some machines there seems to be a common connection for docking
stations/ultrabase.
Had this been caught soon enough the jack could have been replaced, but at
this point I think the only cure is a replacement system board. However,
you can examine the board and see if there is a blackened spot that can be
scraped and resoldered.

Subject: [Thinkpad] x31 + ultrabase power intake problem
My apologies if this comes through for the second time, im having some
trouble setting this mailing list subscription up - hope this works...
Hi everyone. I just bought an extra x31 + ultrabase on ebay. It was sold
as defective with no error explanation. Thought I could get it going, but
alas... =(
Problem is it wont recognize power input. same goes for the ultrabase, so
im thinking psu probably burnt one intake, and then the guy i bought it
from, tried the other one and fried that one as well. He had some "lame"
excuse for not including the psu in the sale, as he would use it for his
new pc, but im thinking it was fried and he knew it.
The psu I am using now is working, as I use it for my primary x31 but it
wont turn the ebay one on, with or without battery inserted. However if i
take my freshly charged battery from my working x31, the ebay one comes on
and seems to work flawlessly. Same goes for inserting battery in the
ultrabase, or letting it power from the laptop. All works. It just wont
take power from psu , which in effect makes both devices useless.
So what I really need is help for a verdict: Strip the parts that can be
reused, or is there any solution to make either device working again? I
have no soldering experience, but wouldnt be afraid to give it a try, as
the alternative is worse, I think..
Any input/ideas would be appreciated...
Thx, Jon
