T400 won't turn on anymore

Today I made a change in my BIOS and after that the laptop didn't boot anymore. Some leds come on (bluetooth, Z, and the AC led), the fan starts for a second, stops and starts permanently spinning after a minute or so. But the screen stays black. 

 

I have tried on AC, on battery, on both. Removed both.

 

Furthest I have come by unplugging the BIOS battery. It boots then, and gets me into the BIOS, but as soon as I save and exit, and the screen goes off, I am in the same situation.

 

I have also tried pressing the power button 10 times in 30 sec intervals. Not sure what that should do, but it didn't help me.

Re: T400 won't turn on anymore

When you get into the BIOS, can you hit F9 to load defaults and save?

I could actually. But when it rebooted again (after save & exit) it complained that the date is not correct. Then when I tried to correct that, I got again in the same problem. Black screen, no boot.

I bought a new one and transferred my data. My problem is solved. Don't know what it was.
