Unable to boot-up Compaq presario 2100 after bios update

I updated the bios of my laptop compaq presario 2100 and after that I can't boot-up and there was no POST at all. I googled my problem and was suggested to clear CMOS but when I opened up my laptop I can't find the CMOS battery on the motherboard. Hope someone can guide me here and many thanks in advance

  1. I've had the same problem (presario 2100) and it looks like updating the
    bios can somehow kill the bios. I don't know why Hp/Compaq didn't warn
    us all of this darn predicament, specifically of this model and the like.
    Anyway here's what you can do as a last resort if nothing else can be
    done. You'll have to change the bios-chip which is located in one of the
    panel-board opening for your min-pci wifi card at the bottom of your
    laptop. Unscrew the panel and you'll see beside the wifi card a very small
    ic-chip known as your bios-chip. If you don't know how to extricate this
    chip ask someone who knows how to do it for you. Anyway, most likely
    the specifications for your chip are as follows:
    PLCC BIOS Chips 1
    VERSION: Default
    ModelNO: Compaq Presario 2100US
    Extra_Info: 32 pin PLCC
    Go to http://biosman.com/ and with the info above order a new chip to
    replace your old one. My Presario 2100 now works after a long time of
    not having a working bios chip and knowing I should never update the
    bios, for good.
