how can i break bios password without remove cmos battery
just remove cmos battery....& try to start pc...
Most likely the small battery inside the case that powers CMOS RAM needs replacing.
A slot on the motherboard intended to hold the CMOS battery.
No. Only the BIOS settings and password are stored in the battery-backed CMOS memory. Windows passwords are stored in the Windows registry, in a file on your hard disk.
There are none. One is a battery which is used to provide passive power to the CMOS chipset to keep it from clearing itself.
CMOS battery
Turn off the laptop, remove the battery. Remove the cover, and remove the hard drive and the CMOS battery. Count to 10 and put the CMOS battery back in the computer. Get a power drill with a 5/16 metal tip bit. Drill several holes in the hard drive, through and through. Get a new hard drive.
Your best bet is to remove all system batteries, and the power cord, then remove the CMOS battery, and wait like at least 20 minutes. Then put the CMOS battery back in, and then the system batteries, and power cord. You will have to set the clock, and boot order, as well as any system specific settings.I got that you have to remove the cmos battery. My Question is about just that. what comes off the back first. I have a Acer Travel Mate 6460. I am not opposed to removing the back cover and getting to the Cmos Battery. I just need to kn ow the process. I don't want to cripple the machine for ever being ignorant. I need instructions with a couple pictures or plans so I do it correctly. Do you have any plans or scematics for the Acers?Read more: http://wiki.answers.com/How_do_you_reset_your_bios_password_acer_travelmate_2420#ixzz1dhffNwrQ
Chances are that the CMOS Battery on the motherboard is dead and needs to be replaced. Without this battery, the computer can not remember the CMOS settings when the power is turned off.
You would dispose of such as you do any other battery.
small battery located on the motherboard or computer case.
