    i'm getting error the same like bentenmen was getting maybe.
    everytime my computer boots up, before windows comes up it gives me a message like this:

    CMOS checksum error - Defaults loaded
    Warning! CPU has been changed or CPU ratio changed fail.
    Please re-enter CPU setting in the CMOS setup and remember to save before quit!

    then i have options F1 and Del [set up]
    date and time is not correct when windows comes up.

    at the top it says:
    Pri. Master Disk HDD S.M.A.R.T. capability....Disabled
    Sec. Slave Disk HDD S.M.A.R.T. capability....Disabled
    <is this right, what am i supposed to do to correct it?>

    when i changed settings in BIOS i got this:
    Verifying DMI Pool Data
    Remove Disks or other media
    Press any key to restart...
    <i don't know which part configuration in BIOS caused this, but when i press any key windows will come up properly but it is irritated that everytime i use my computer i need to do the same process. HELP?>

    and also: what is "F6: Fail - safe defaults and F7: Optimized Defaults" for?
    i'm running XP [don't know if this one can help]

    sorry guys, im trying to learn.

    any help would be appreciated.

    Please do not hijack an existing thread - always start your own. The problem you describe is not the same as that of the thread starter.

    I have moved your post to a new thread with an appropriate title.

    CMOS Battery?

    Hi Tyler, the symptoms you are experiencing can be caused by a run down CMOS battery. When was the last time the battery was changed? If you think it might be the cause, get a new one and replace. They are inexpensive and take only minutes to change. Can be purchased at most electronic stores and pharmacy stores that sell watch or hearing aid batteries. It's about the size of a quarter (US) and should be numbered something like CR2032.

    it's 3 or 4years old now. i'll change it.
    but what about the part:

    Pri. Master Disk HDD S.M.A.R.T. capability....Disabled
    Sec. Slave Disk HDD S.M.A.R.T. capability....Disabled

    is this fine?

    thanks for the help, JohnB.

    Hi again, the SMART monitor (lets you know if the drive is about to fail or is failing) of the hard drives can be reset in the BIOS. Not sure where in your BIOS the setting is but you should be able to find it and set it to ENABLE. It is not critical to the operation of the computer and many feel it is of marginal use as when you get an alert from the SMART technology it is probably too late to rescue your drive. At best you may be able to transfer date off the failing drive before it quits completely.:eek:

    Your SMART setting is probably resetting to DISABLE as a default due to the battery dying. 4 years is a long time for the CMOS battery to last.

    Hi John(B),

    I always run CHKDSK (Error Checking), if there seems to be a problem about SMART
    http://support.microsoft.com/kb/315265

    Test the disk surface.

    After running Error Checking, do a defragmentation.

    These might be "old days" suggestions, but be careful if your HDD might be having problems.

    CMOS battery, good suggestion. It might go back to "normal ". Check everything anyway.

    Matt

    johnB,

    thanks for the help and information.
    as of now i don't have the result to post as i don't have a new CMOS baterry yet.
    but i tried changing it to "Enabled" then save it and when i turned the computer off and turn it back on after awhile it auto changed it to "Disabled" again.

    but, as i have said i haven't tried changing the CMOS battery so crossing my finger once i change it everything will go fine.

    Thanks again JohnB. You're a great help. i really appreciate it, bro.

    This is a failing/failed battery, the CMOS although low power requirements still needs power, by default most (all?) BIOS have SMART turned off. You can save any settings you want but without a good battery they won't stick.

    My advice, don't worry about any settings SMART, Time/Date etc untill you change the battery. Once you've done this and still have problems then post back with your issues.

    ok at least that is good to know.
    hopefully, i could go to the market as soon as possible to buy CMOS bat.
    and hopefully, that old CMOS battery is not that difficult pull out or else i might break something.

    i'll keep you posted, folks.
    thanks for this lot of information.

    Hi again Tyler11,

    Changing the battery should be very simple, most systems nowadays use the same type battery, a flat button type around 1cm in diameter.

    Changing them is easy but static can be the killer and residual power isn't good either :(

    Obviously disconnect the system from mains power completely, after you have done this, a couple of tips...

    If your PSU has a hard power of switch (ie on the back near the power cables) then leave this switch on

    If it's a soft power switch (ie on the front of the case) then press and hold for a few seconds (30 is good).

    This will allow the capacitors on the mainboard a chance to discharge and reduce the likelyhood of any problems.

    i have changed the battery and everything works fine now.
    i am noticing the smart, no matter if is disabled or enabled. not seeing any difference.

    bottom line, computer works fine.

    thanks so much for the information and help, folks.

    You wouldn't unless something was going wrong (when enabled) and you use additional software to monitor for potential problems.

    Thanks for the feedback, hope everything continues to work well for you.

    Thanks for the feedback Tyler, yes, the SMART does not appear to do anything, but would advise you if the drives were failing. You would then have to use additional diagnostic software to find out what the problem(s) were. Don't worry about it.
