need the system password
Only way to remove a BIOS password on any computer is to remove all power sources from the motherboard so its memory can be cleared.
First, remove the main battery from the laptop. Then you must locate and find the little coin cell battery (It looks like a watch battery) on the laptop and remove it for about a minute or so. Then you can replace them in the opposite order.
Your coin cell battery is in a bay on the bottom of your computer. Enjoy!
1. Before removing the coin battery:
3. Use a Phillips screwdriver to remove the two screws securing the cover.
4. Lift and remove the cover from the system.
5. Locate the coin battery.
6. Use a fingernail (or small flathead screwdriver, if necessary) to release the blost system password - exmem08.jpgconnector.
8. Reverse the previous steps to replace the coin battery.
