T410 power on password problem

hi,

 

i have a t410. it was working normally. i removed the keyboard for a reason, then place it again. After that, i powered on and black screen appeared with a small lock icon upper left, requesting password. as far as searching on google, it should be bios password. i cannot enter bios as well.

 

i removed the keyboard again to remove the bios battery, removed it, waited for a while and place everything. i powered on the computer but it is the same.

 

1- why it doesnt appear before keyboard removal and started to appear after that?

2- how can i handle that?

 

thanks...

realistically, the only thing left for you to do, is to call Service for further advice.

Removing the bios battery will provoke a requirement to enter the supervisor password. At boot press F1 and when you see the "lock" symbol, which is the same as the power on password symbol, enter the supervisor password.

 

If you are not in posession of the supervisor password you will need to contact the previous owner or support as suggested by sarbin.

 

For the reasons already stated by sarbin - thread locked.
