You can ask for a bios pw reset from the computer manufacturer tech support dept.they can try to reset the pw for you,but if that does not work, the motherboard needs to be replaced on your system

If you are able to remove CMOS battery (from inside laptop; there is connector for it) and wait for an hour or two and then replacing the
connector of battery...Bios password will be reset. Warning ! All these operations must be made after you remove main battery and
of course, unplug the power supply. As an exception, for some Toshiba only, this method doesn't work at all. There are some jumpers on the motherboard (near CMOS battery) but is very risky
if you don't know what to do....let's say so.
So, try the first method as above. Remove connector of CMOS battery (all operations without main battery and power supply cable)
wait an hour...two...replace all and I think all will be fine in your case.

Hi I am having a ACER TRAVELMATE 4720 LAPTOP I forgot the CMOS password kindly help me..


when I have had this issue in the shop, we would open the bottom of the laptop , find the cmos battery (looks like a watch battery) and short out its terminals for a minute or so. this will reset the bios to defaults, and likely dump any passwords set in the bios. if this helps you leave some feedback. Cheers

There is only one way to clear cmos (BIOS) passwords and I'll show you the procedure.....

Steps for Clearing BIOS Password Check

If users set BIOS Password ( Supervisor Password and/or User Password ) for a security reason, BIOS will
ask the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the HW Gap to clear the password by the
following steps:

q Power Off a system, and remove HDD, AC and Battery from the machine.

q Open the back cover of the machine, and find out the HW Gap on M/B as picture.

q Use an electric conductivity tool to short the two points of the HW Gap.

q Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the
system till BIOS POST finish. Then remove the tool from the HW Gap.

q Restart system. Press F2 key to enter BIOS Setup menu.

q If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and
try again.

NOTE: The steps are only for clearing BIOS Password ( Supervisor Password and User Password ).

Below is the picture showing the location of the jumper next to the memory module slots. This is the jumper connections that have to be "shorted".
