u will need to open the laptop, there on the mainboard u will find a battery, u have to remove the main battery and remove the laptop from current. its a small round battery u have to remove it for some 5secs just to clear the bios memory, then put it back back. the password wont be here. if there is no round battery then u will find a jumper that u have to short it. else remove the hard disk use a USB cable transfer cable to use it on another pc or laptop to recover your information

I believed this can be resolve by clean the cmos battery. you need to remove the cmos batery from the laptop then power it on then immediately turn it off. then put the battery back to the laptop then power it on keep tapping on f2 to enter setup. please follow the instructions from the link to remove the cmos battery http://tinyurl.com/yb3mhyg
