Hello everybody,

 

I have been using CQ 41- 208 AU since July, 2010. last week I tried to turn it on. Then the caps lock and num lock started to flash. I checked the codes for flashing and my one is flashing for more than 6 times, which means to be "Bios authentication failure" if  I am right. Now any body please tell me how can I get my laptop operational again. 

 

In the mean time I tried to run the laptop with out Ram, with out hdd no change.

 

I connected external monitor but no luck.

 

 

Pls help me , thanks in advance.
