IF THIS COMPAQ IS  NEWER THAN 3OR4 YRS  IT IS SIMPLE.  THAT BATTERY THAT YOU ARE SPEAKING OF  IS ABOUT THE SIZE OF A NICKEL  ?  THAT BATTERY IS CALLED A CMOS  BATTERY .FIRST  OFF TRY CHANGING YOUR TIME SETTINGS IN CONTROL PANEL.I`LL  ASSUME ITS A DAYLIGHT SAVINGS ISSUE .  WHEN THAT BATTERY GETS OLD  OTHER THINGS WILL HAPPEN B4 YOUR CLOCKGOES  AWRY   CMOS  STANDS FOR  [COMPLIMENTARY  METAL  OXIDE SEMICONDUCTOR] YA I KNOW    WHILE YOU ARE  REMOVING CMOS  1ST  DISCONNECT POWER  2ND  USE A  PLASTIC  DEVICE TO GENTLY REMOVEIT. 3RD  WHILE  YOU ARE  IN YOUR CAGE MAKE SURE  ONE OF  YOUR HANDS IS TOUCHING THE METAL PART OF THE CAGE TO DISCHARGE THE BODIES STATIC ELECTRICITY.STATIC DISCHARGE CAN FRY YOUR WHOLE SYSTEM RARELY .THE BATTERY   IS PROBABLY A CR2032. ENERGIZER

the bios password is to just stop people from making changes, but you can only do it if he's physically @ the computer.\n\nOther than taking out the watch battery (it's about the size of a quarter), if you didn't buy it (Dell, HP, Compaq, Gateway etc), you might have the manual and can reset it using the jumper.\n\nP.S. Becareful in there, if you use a screwdriver to pop out the battery and you miss, that could mess it up more than even your nephew could :)

Your Motherboard has a small Lithium battery which allows the clock ticking even when you shutdown your computer..\n\nOnce it exhausts.. all you have to replace it and then again setup the time...it wont vanish now!\n\nRead a detailed article regarding how to replace the battery at: http://www.hardwaresecrets.com/article/81\n\nIf replacing a battery doesnt solve your problem...you may have to upgrade your Motherboard CMOS by flashing it...\nContact DELL Service Center for this..\nBut..mostly battery replacement solves the problem in 99% cases..

Just did a quick google search and came up with this :\n\nhttp://www.amdboard.com/ocspecial.html\n\nI have never really over clocked anything as that tends to shorten its life span since it isnt meant to run at the higher speeds.

go to the Compaq site and download the manual

Computers have TWO clocks built into them.. one being the CMOS clock,, the other being the Real Time clock..The battery keeps power going to those when the computer is not plugged into electric

if your bios is losing its information check the battery on the mother board. It is one of those round watch batteries.

Try opening the time/date,,while you've got it open tap the space bar a few times..If this don't help then your CMOS battery is going bad.

you must savew or write the data in the bios of your computer, then open your computer and look on the mother board surface for a battery like the button shape, these used in calculators and clocks (near 3/4" silver circle).\nchaeck that it is not soldered on surface, if so, yo must need professional assistance. else, it must be mounted on a socket, just press a side of it and will be free, then take it to an electronicss or photography store and buy another OF THE SAME TYPE, not one that looks like, and put it in the place of the other.in the main cases you must put the negative part downside (the battery descriptions and the (+) sign is on the upper side), but take note of this before remove the old. after replace it, just turn on your computer and enter to the bios and restore the old values or let the computer to take the default and just start your operatinfg system and update time and date.

1. Duracell\n2. Energizer\nBoth batteries will make a clock run for over a year.

Open up the Machine....Just Check the Motherboard...you will Surely Find the Battery.......

Ok there are two ways to do that.\n1. Remove the CMOS Battery from the motherboard.\nSo you need to open the case and you should see a thin battery,just remove it for 1min and than put it back and bios should now be reset.\n2. Some motherboard has a jumper (pin) to the clear the cmos.\n\nThe removing of the battery works almost all the time. If it doesnt work please update your post with the specific e-machines model you have so I can better help you.

A few questions:\n\n1. Have you corrected the time?  If you have, does it reset to the incorrect time when you reboot?  \n\n2. Do you have the correct time zone set?  If not, the minutes will be correct, but hours will always be wrong, because Windows automatically synchronizes the time based on the time zone YOU give it.\n\n3. Is the computer connected to a network?  Some Netware networks will override the time setting on the computer.\n\nEven if the CMOS battery is bad, Windows should automatically set the time when it contacts a time server.

As with any problem, you start from the simple and work your way to the hard.  If you have correctly reset the computer time and it does not stay correct, then replace the battery (my money's on that).  Remove the side to your computer (while the computer is unplugged), you'll see the watch-type battery.  Remove it, take it with you and go purchase a new one.

well if its a ibm thinkpad it should be under a cover on the bottom possibly where the ram slots are. you will see a small yellow disk with a red and black wire coming off plugged into the motherboard. unplug it and twist the disk off it is sticky taped to the mboard. you can the get ripped off and order a plug in replacement or do it the el cheapo way like me and buy a calculator replacement battery it does not have to be the same model number but it does have to be lithium and the same voltage. cut off the heat shrink and cut off the tabs then resolder with the CORRECT voltage + and - wrap it in electric tape then plug back in restart your computer and it should work.
