i have a notebook - fujitsu LH532. Since it was slow, I reinstall from win8 to win7 with USB. After that, I need to plug in the same USB for booting and enter to windows. Thus, i want to enter bios and change boot sequence.
But, bios is locked and i forgot password. So, i want to reset bios via remove the cmos / the battery on mainboard. I do not know how to disassemble notebook, so i only can reach a part of ma inboard rudely.
I press the "White button" (i guess it is the button for clear bios). Then, i power on notebook. There is nothing shown on screen!! The power button flash and cannot enter to windows.

Can someone help me to solve such problem. Thank you some much!!

1. Your pic doesn't work.

2. If there's a BIOS password on it and you don't know it, we cannot help you.
Forum rules specifically preclude assistance with passwords.
