    Is your computer old enough to need a board battery replacement (3-5 years)?

    Some software (including security certificates) cannot cope with the computer's date being more than a few days out.
    Almost invariably the problem will be that the CMOS battery, usually a flat, thin, silver Lithium Ion battery disc about an inch across, known (in the UK, at least) as CR2032, probably, has become depleted and needs replacement. You just have to look around the motherboard for something which looks like I describe, find the reference number from the surface, buy a replacement, and replace it. You may need a small, flat-bladed screwdriver, which you should wield with care. Of course, power off and remove the mains cord well before you start messing around internally!

    Undoubtedly you will know almost all of this...

    If you post the make and model of your computer, we may be able to find the service manual or a Google on how to replace the CMOS battery on it as some are soldered to the motherboard.

    I have never come across a CMOS battery that was not replaceable by the application of a screwdriver and a little care.

    Here's a Toshiba and I believe they are also soldered on some ASUS models http://www.tomshardware.co.uk/forum/...ttery-soldered

    That's quite wicked! Saving a few p / ¢ on a plastic battery holder.

    Agreed - I have a Toshiba laptop and to reset the BIOS I would have to remove the RAM modules and the slot tray (don't think they are called SIMS now ?) and underneath is a board where you have to short two pins.

    This is standard for Toshiba although the location of the board/pins can vary.

    I found the CMOS battery, they have it tucked under the HD, fun, fun, fun. Is there a certain way to remove it, I've ever replaced one.

    See my previous comments! Once you've done this, get a small screwdriver, and insert it just next to the edge of the battery, and push gently towards the other side. Move round the battery, continuing to push gently towards the other side (there should be a spring somewhere on the other side), until it pops out (and possibly gets lost somewhere inside the system unit). If that doesn't work, you may have to lever it out!

    Qwest,

    Looks like it's in the extreme corner of the mobo; it is, indeed, a CR2032 (very common) battery.

    Not sure what type of cleaning you did, but is the date correct in the BIOS ? If it is wrong, Windows sometimes will not let you reset it.

    Definitely replace the BIOS battery ASAP even if it takes some work!!

    > 6 yrs in Dec

    Definitely should be replaced, most probably the problem and if you leave it much longer it'll leak corrosive juice onto your motherboard.

    If it's a laptop (sounds like it, with hard drive covering the BIOS battery), you should be able to open a hatch underneath and lift out the hard drive, get the manufacturer's pdf manuals from their website to suss this out (screws are sometimes under rubber feet which need to be removed & reglued). Go to Youtube and search on your computer's make and model with the word 'dissassemble' (also try 'dissassembly'). Unless it's a rare cheapo there's almost certainly a great guide there. Obviously put it on a second computer or fully study the video before starting laptop dissassembly!

    Allocate lots of time for dissassembly, and if you'll be doing much of it, buy a jewellry organiser like this one for holding all the screws (hang it on a doorhandle or clothes rack with a hanger, put a little note with each set of screws in their pouch explaining exactly where they go for reassembly) and take lots of pics with your digicam or phone during the process so you're not left at the end with the proverbial few orphan screws.
