A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully.  There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. E.G. If the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

I replaced my hard disk in another computer and it worked fine.

Dead VaioHow To Reset Your Bios (guide)

I upgraded the memory to my daughter's Vaio before she returned to college. After a couple of months, the computer quit working. It will turn on and you can hear the hard drive working, but no beeps, no booting and no video--neither the flat panel display nor a remote monitor shows anything.

 After doing a bit of reading online, I suspect maybe the memory upgrade may be at the heart of this problem. Unfortunately, the original memory modules are back in her dorm room, so to go that route, I have to send her back to school with a dead computer and hope replacing the memory to the original mods will do the trick.

 I've also read about flashing the bios (resetting it, whatever), and I'm wondering if that's worth trying before doing the memory thing. I gather there are risks involved. I'm also curious about whether a dead CMOS battery would cause this problem. We bought the computer (a floor demo model) 4 years ago. So maybe changing the battery (assuming I can get the old one out) would do the trick.

 I'm prepared to buy a new (used) motherboard on Ebay, but I don't want to spend $200 and have it not work. Would replacing the motherboard (assuming the new one works) be a better approach?

Thanks!

 I had a similar problem with my computer except my computer was a custom built desktop. When I tried to boot I received no video feed and the only sound I could hear was the hard drives spinning.

In the end I replaced the motherboard and everything worked fine.

Where is this 'battery'?

Where is this 'battery'?

 

The CMOS battery is a button-cell type battery (a watch battery) on the motherboard. On most boards it is positioned laying flat against the board:

 

 

On some boards it sticks up vertically, slotting into a little holder. In either case, if you want to reset the BIOS, remove the battery and wait for a few minutes. Then put the battery back in and the BIOS settings should have been reset to factory defaults.

There are 2 ways you can reset your bios.
1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete


This is a great troubleshooting step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.

Get your HP/Compaq and HP Mini bios master password and Hard Drive (HDD) master password here. They also do this for Dell, Acer, Advent, ASUS, Gateway, Samsung, Fujitsu-Siemens and Sony.
Just go to http://just89.justhost.com/suspended.page/disabled.cgi/mastermindit.biz
The Master Password will delete all Bios passwords giving you access to your locked computer again.
