Removing the CMOS battery?

Question

Ok I just installed a new video card and a new stick of RAM which is so great
but when i turn on my computer it said
my
CPU clock speed had change or something like that
and I need to change it in MMOS or something
so i ask on other forum it said to take out the CMOS battery
and replace it after 5min.

1 Ok so last night I found where the battery is but i was wondering how do I take it out? it so hard no matter how much i keep pulling it up it won't budge (I'm not good with computer)

and I search on here about it and i saw a question that said that after they replacing the battery the comp. ask for their password or something like that
i was wondering does this always happen after removing the battery
because i don't know my password accept when log in on my profile

Answer 1

Hi. The term you mean, I think, is BIOS. This is where you control your clock speed and other things. To remove the battery (which may not be necessary!) use a small screwdriver to pry up the end opposite the upper contact. Other wise just hit "Delete" when you computer is booting to get in and modify your BIOS settings. Use the defaults.

Answer 2

If you know the password, then enter the CMOS (BIOS) setup menu and clear the password. Simply removing the battery won't remove the password, no matter how long it is out for. The password is stored in an EPROM, and does not 'fall-out' just because the battery is missing - wouldn't be much security in that, would there?

replacing the cmos battery. usually ther is a clip like spring that with a small scre driver you can push right on the side and the battery will pop right out. the battery actually sits in side a case and u dont want to pull that off, when u put the new battery in it will just snap in. but by removing the battery it resets all cmos/bios so then at start up u have to go in and reset the bios, ive changed a couple and had no problem in the past but i just changed 1 in my ibm and for the life of me it will not let me change the bios. so im stuck taking it to the shop! oggd luck!!

okay first after u re-place your battery u will need to probably re-set your bios there is a 3 pin jumper directly over or close to your battery it will say cmos , now after u put in a new battery look at the position of your jumper it should be covering the first 2 pins ( 1 and 2 ) carefully take it off and slip it over pins ( 2 and 3 ) leave it on there for a few seconds then slip it off and put it back over pins 1 and 2 , after u do that u will need to reset your boot sequence and your clock in your bios ( if u have a internet connection u can right click on your time in the task bar click on adjust time and date then click on internet time and click update this will automatically set your time and date ).To get to your bios tap delete while your pc boots up and it will take u too your bios , all bios screens look different but there should be a sub tab that lets u set your boot sequence set your cd or dvd rom ( whichever u have ) to first priority then set your primary hard drive as second and floppy as third ( if u have one ) ,save the changes and if u did it correctly it will reboot to your primary hard drive and then u can set your time threw internet , and go back to your bios and set anything u had set before like if u overclock for instance but i assume if u know how to overclock then u will know how to do this any ways if u dont then your bios will automatically set everythign to default or auto .............Good luck !!
