Bios password, how do i remove it. I need to change the boot system to install windows.

Unplug the power cord from the power supply.
The fastest way to clear the bios password would be to first find the bios/cmos battery on the motherboard. See the picture below.

Next find the 3-pin bios jumper. Asus motherboards usually mark the motherboard bios pins as, CLRTC.
It will be rather close to the bios battery. Pay attention to the current position of the bios jumper. It is currently set as normal. The jumper will cover pins 1 and pin 2.
Remove the jumper and place over pins 2 and pin 3. Doing this will clear the bios and will reset all bios settings to DEFAULT. Grab a small flat- head screw driver. Gently insert the screw driver slightly under the battery edge to help you to remove the battery. Wait 30 seconds and reseat the battery. Reset the bios jumper back to pins 1 and pin 2.
Reconnect the power supply cord. You will need to enter the bios and re-configure all your settings. Use your motherboard manual to help guide you through all your bios settings. Next time include the model number of your Asus MB.

Happy holidays!

Bios password ibm thinkpad g40

Sounds like you tried this, but it's worth a shot again. Remove the CMOS battery on the motherboard and let the laptop sit for an hour, then replace the battery with a new one.

If the only real issue is changing the time and date, you can do this in Windows and it will reset the BIOS clock, too, of course.

If the problem is that the time and date keep reseting, you either have a low CMOS battery or a short on the motherboard that is resetting it.

If all else fails, you might need to flash the BIOS from a floppy disk with the latest BIOS version for your machine to reset it and go from there.

PS: BIOS reset problems on laptops are sometimes due to power problems caused by battery packs going bad; check your battery pack, too, and see if it is working okay.

Good luck...
