T61p shuts down when on AC Power

When running on AC with and Without battery I get a shutdown of XP.  This also happens if in hybernate mode.  System runs great on battery only  Also was able to trigger shutdow by plugging in the power pulg to the laptop.  Heat seems not to be issue since it runs on battery ok and I have a cooling platform.  Voltage on poer block is 20VDC and it seems not to be running hot.  Shut down does not give any messages nor do I find any events logged.  I reminds me of the early switching power supplys when you had too large of a load on the 12 volt bus.  Brick is rated at 90 watts.  Can not find a common cause.  Tried running same tast on Battery and with power and on pure battery it does not shut dwn .  Shutdowns on power seem to take place at any time.

thaks to all
