    No, there will be no permanent damage to anything, that'd be just silly.

    The system will boot up using the factory settings for BIOS and/or complain about it. Usually you have to enter the BIOS setup or just confirm with a keypress.

    I'd say with 90% probability the system will work just fine, although the clock will be wrong and the the default BIOS settings may not be the fastest. One'd have to manually set the clock and alter BIOS settings after every powerdown for best computing experience.

    Just out of curiosity, why do you want to know.

    I don't think I've got any info to give you that Nodsu hasn't. I just have questions. You're talking about the disk like battery that's clipped to the board in a small housing right? You're not meaning another kind of battery because if you are, do not remove the battery! If it is a disk like battery about the size of a two pence coin (about an inch diameter) and it's just clipped in however you'll be fine to pull it out.

    yes, it is a disk like battery about the size of a two pence coin (about an inch diameter)

    because my inention was jsut to reset the cmos password. so what i did was, i removed the battery and then turned it on (without the battery). then it beeped with a high frequency long beep.

    but prior to that, the power supply (attached to the casing) was replaced because it sparked (i think some short circuit occured). can u please ym me add me to your ym, help me talk about my problem, my ym id i dredvixen, tnx

    Remove the battery but you should clear the CMOS using the jumper setting if you have that on the MOBO. Again you don't have to do this just because you're replacing the PWRSY. Just make sure you buy something larger than 350Watts and make sure you have the right number of power connectors you need. Otherwise you'll have to buy y-adapter to extend the power connectors in your system. That's why it's better to get a larger PWRSY!

    nope, i did not remove it just because i was replacing the power supply. what was really happened is that... first the power supply was broken, it sparked (i think some short circuit occured). then my brother bought a new one to replace it.

    when he has already replaced it, there was display but it doesn't read the disk anymore,(it says system disk failure), i told him to try the disk in other computer, it was the same it was not detected (the hard disk is not reading anymore) so i thought because of the power suppply that sparked, the hard disk was broken, maybe larger amount of voltage has flowed through it??? do you think so???

    when he attempted to go into the cmos his password was not recognized. thn the system just restarted.

    so what we did was, took the battery (a disk like battery about the size of a two pence coin (about an inch diameter)) off the board and turned it on. we turned it on without the battery then that's when a high frequency long beep was sounded.

    so, is it because of the battery that causes the ruin of the cpu and hard disk?

    Is this somethng you both built (clone) or something you guys got from one of the major players who make PCs?

    What was going on when the problem happen? Were you on the pC when the powersupply just sparked?

    The battery backups the BIOS info passwords an etc. Long beeps you need to go into the BIOS and change the clock settings. Well you could do this in dos (black area) but it's better you go into the BIOS change the clock and date. Also anything else that you don't have in there should be disabled.

    If the HDD is bad as you have mentioned then you'll have to replace it..

    well.. yes

    i wasn't there but my bro told me that it sparked.

    when i tried to boot the computer it doesn't display anything so i can't go into the bios. what will i do now? does this mean that i have erased the BIOS?

    Removing the coin battery and turning the pc on cannot do any harm. You may get a beep or other sounding noise but thats all, just turn pc off and put battery back in.

    A cheap power supply that comes with a system will take other parts with it when it "sparks" or short circuits. From the sounds of it you had a cheap power supply so its likely other hardware has been damaged. It all has to be tested in other systems or by someone who has the ability.

    Bios isnt erased, its only been set back to original condition, you would have to go into bios and set parameters such as your first boot to c. Right now its likely first boot to a: and maybe that is why you are getting errors.

    From the wording of what you are saying you and your brother need to find someone to help you with these problems.

    I think it should be called PSU (Power Suply Unit) or a converter.
