Omnibook 600ct Docking port pinout ???

[Jonny54]

Hello,

The original mouse device on my laptop Hp omnibook 600ct is broken.

I try to put a serial mouse on the serial com: port 1, that work but for a very short time,
i think theres is a problem with the internal com port :

as soon as the machine is cooled the COM: port  Re functions ?

I wondered, if there were not average to draw some wire starting from the docking station connector (rear the computer) in order to constitute, and to connect a PS2 Mouse plug..

Because the docking station interface provided by HP, had a ps2 mouse connector  .

Thanks in advance
