I have Thinkpad T60 and docking station 2504. Even though the USB ports on the docking station are active, the DVI port is not, ie it does npot send any signal to my external NEC monitor. Any idea what might e wrong?

Try a power adapter with more amperage. When you connect a dock, the 3 amp adapter that comes with IBM laptops will not have enough power for lots of add-ons. You'll need the 4 amp adapter.

I unplugged the moniter, mouse keyboard and power. I plugged in the mouse, keyboard, moniter and then the power. I placed the laptop on the docking station and it worked.

No just find other doking station. refers to the Lenovo web page

This sounds like a common feature of the T60, when docked it requires a reboot also try to reboot 2-3 time a day to help cooldown. IBM is a quality machine, even go as far as buying cooling extention for the T60.

Dear rajeshraja42,
Try to run the recovery CD from IBM Docking station, and reconfigure your system by connecting your docking station while you run them.
Or try this:
Connect your docking station to your Laptop then turn the Computer On!
Start>My Computer--- Then right click--- Choose 'Properties'>On the dialog box, ----choose the 'Hardware' Tab> Choose the Device Manager box by click them>Now You are in the DEVICE Manager Box>>>
Run the Scan For Hardware Changes... Then if you find that your docking station appear with Yellow Question Mark Then, right click on it and choose 'Uninstall' from context menu and answer YES! then Run the SCAN for hardware changes for ONE last time, Your System should find your Docking station as part of your system now!

GoodLuck!

Best Regards,

If the docking station charging doesn't work either and your battery is ok you have lost voltage regulator (it prevents overcharging of battery) Take the battery to a battery plus store and they can check it..

yeah, you can set the display setting as extension display your DVI

Intel, ATI,Nvidia have tools also to set up,

i have ATI and use the ATI Catalyst tools and autodetect the monitors that i connected to my docking station, intel and nvidia also have this utility.

it depends on setting if u wanted the external monitor as CLONE monitor of your laptop or extension Monitor...

or they might have problem on DVI port of your docking station.

download and install the video utility ( must have .net installed before you install the utility)

the utility will detect your video ports (VGA,DVI,S-video)

let me know the update ..

I have the same docking station and I am typing this on my T60 right now. I have noticed that sometimes it is very hard to dock my laptop and other times it just slides on instantly. This seems to be an issue with poor design. If you look a the dock connector under you laptop you will notice there is a strip of plastic in the middle of two rows of connectors. The docking station connector must be perfectly aligned to successfully connect. I would inspect it for any damages, but honestly I think it is just an issue of patients, precision and a little bit of luck. If you can not identify any damage I would just slowly try to line it up and keep trying until it clicks. Remember to never force it and once it lines up it will slide in with very little force.

I was having the same problem - the USB ports seemed to have stopped working so I could not use the mouse, keyboard, or printer, even though the monitors and power could still operate through the docking station. Finally, I just unplugged the docking station for 30 seconds, plugged it back in, and everything resumed working. I was surprised it was that simple, but it's working for the moment.
