That sounds like a SouthBridge chip going south, pretty much all the symptoms are there.
Your options are to have it professionally re-balled (no-reflowing of SouthBridge, unlike GPU) or have motherboard replaced. Good luck.

I have a T43 2668, the 15"/1400x1050 thing, running Debian GNU/Linux sid. It works in general, but battery live is not as good as it should be (around 2h with a "almost like new" battery). I guess the messages like hub 2-0:1.0: over-current condition on port 2 "spamming" my syslog may be the reason, most definitely a hardware issue. If memory serves right the message is / was not limited to port 2. Iirc port 1 messages were there too at one point or the other. I do get occasional hardlockups / kernel oopses every once in a while, I guess depending on the kernel version that varies from kerneloopses to screen-freezes with a nasty beep sound playing until powered down the hard way. I do not see the issue often known as the "flexing-issue" here as: 1.) has never been reported for a T43 2.) no screen flickering / errors. I think the T43 did work without lockups for several months and the lockups did happen later, but the "usb over current" message were there all the time. As this is not my only laptop, I did not bother much and just took another one for work. But now as another ThinkPad did fail me (see the next mail) after a hard 1,50m fall, I guess I have to stop breaking ThinkPads and trying to fix em again! ;) So for this little black beauty, any suggestions where to look for short-circuits / wrong wiring / broken connectors / whatever? I have never disassembled a thinkpad entirely (at least I had never the mainboard of one in my hand), but I did some minor hardware maintenance in the past and with the maintenance manual provided by IBM/Lenovo, I am confident to be able have a look at every inch of the inner guts of it if necessary. Any help / suggestions is greatly appreciated! regards Michae P.S.: wrong e-mail account used the first time... _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad _______________________________________________ Thinkpad mailing list [email protected] http://stderr.org/cgi-bin/mailman/listinfo/thinkpad
