If you like to reset your laptop password and default settiings by removing the cmos battery, it will do.however you should first disassemble the bottom cover. if you see the battery just remove then return
Try removing the battery on your motherboard and leave it out for 10-30 minutes (See page 65 of your owner's manual) . Make sure the power cord is removed from the PC when you do this. Replace the battery and see if this resets your CMOS memory in the BIOS, where I am presuming the password is set if you are getting this message immediately upon startup. There may also be a jumper on the motherboard that might reset the CMOS. If this isn't a new computer, or is a refurbished computer, the previous owner may have set the password and you could contact the place you got it from to have them fix the problem.
There are two possible reasons for the time and date to reset to the date of manufacture each time the machine is booted up.
The back-up battery is dead and needs replacing, usually it is a CR2032 but check what is stamped on the battery.
The bios reset jumper, on the motherboard, has been left in the "reset" position. Check the manual for your P.C., it will show you the location of the jumper and it's reset and normal positions.
If you don't have the manual, you might get it at:-
Power down PC. Open the PC tower. Look at the motherboard and find the CMOS battery. Looks like the picture below. Make sure you touch some sort of metal area on the PC to ground yourself before touching the components. Use something thin to pop the old CMOS battery out. The CMOS batteries are usually universal. CR2032 is the usual type used. These can be found at a CVS or Walgreens. Once you have acquired the next battery, make sure the CR2032 is facing up and just press it in.
your Gateway computer is
switched off, it still keeps track of various system information such
as the date and time, thanks to a small battery that never powers
off. The size and thickness of a dime, the CMOS battery can run out
and need to be replaced. You can swap out a dead CMOS battery with a
new one by removing the Gateway computer's side access panel.
4 beeps of equal lenght suggest that system timer is not working, you
need to change cmos battery on your computer. If you are game, that is how
you change CMOS battery on your computer, takes about 5min, required tool is phillips screwdriver:
1. Switch off computer, remove power cord 2. Remove left hand cover (this is cover which is on lyour left while you stand in front of the computer) 3. As you look at computer "gizzards" on right hand on the motherboard you will see silver battery about nickel size, it is located in this computer about three finger width from the bottom of the motherboard and about 1 1/2 finger width from right edge of the motherboard. Unlatch it and remove it. Purchase exactly same battery, be it in drugstore or hardware store. 4. Slide in new battery, + is up, towards you. 5. Mount back side cover 6. Re-connect your power cable and start the computer
You most probablay will need to re-program BIOS as all information is lost when this particular battery die.
This should solve your CMOS batery problem. Of course you can send your
laptop to the technician but that will be no fun at all... ;-)
