I have a Thinkpad T61, I was using my laptop the other day in its docking station and it suddenly Powered down, I mean just shut off, hard drive span down, no error message and all power lights on the machine turned off. I took it off the University with me. Then when I turned it on it would get the the windows loading screen and then shut off in exactly the same way as before and it wouldn't even turn on again until i took the battery out and put it back in. I tried every combination of battery in with, and without power supply, with just power supply and battery out and the same thing still happens. I have tried booting it up in safe mode and the same thing still happens then. I plugged it back into the docking station and it all worked fine again, but this keeps happening and I can't use it again until I plug it back into the dock. Does anyone have any ideas on what could be happening??
The Thinkpad T61 is a Lenovo Laptop. You have to go to a Lenovo showroom and ask them to help you. Otherwise you have to go to an electronic showroom (that sells lenovo laptops) and ask if they can assist you.
