  1. If you do a google search for B5787, all information just points to your main battery... not a cmos battery. There should be a slide clip on the bottom of the case (maybe a couple screws as well), that will unlock the battery and then you can slide it out, and replace it with a new battery.

    Hope that helps.
  2. Thanks so much for the quick reply.
    However, not the regular battery that needs to be replaced,
    perhaps I am using the wrong term. The computer needs to have
    the little battery that is used to tell the computer how to boot up
    once the power on button is pressed.

    Any ideas about where it is located?
    and if it can be replaced easily?

    Thanks for your help.
  3. What issues are you having with the computer that make you think you need to replace the cmos battery?
    In order to find and replace it you would likely need to disassemble most of the computer. The battery is about the size of a nickel and would be located on either the top or bottom side of the motherboard.
  4. Thanks, the prompt read something like, can't load system, computer is old
    and was being used alot over the summer without any problems, so I figured
    the cmos went bad.
    What do you think?
  5. you should check again what the prompt says, could also be an issue with the harddrive.
  6. OK Thank you.
    I'll be back in touch!

    if it is the cmos battery then it is gonna be a major pain in the @@@ to change, as already stated it is a watch battery on the MB and some are soldered on

    I doubt your battery is the problem ,what are the exact error messages and what have you tried to solve it

    though slightly inconvenient it is entirely possible to run a computer with a dead CMOS battery, and that would be my recommendation if it is in fact the problem
  8. It says:
    configuring Panel 02 - Color 18-bit XGA TFT
    Booting Panel Only Display Mode
    BIOS VERSION 10.08
    CPU = Pentium II 300MHz
    0000640K System RAM Passed
    0512K Cache SRAM Passed
    System BIOS shadowed
    Video BIOS shadowed
    System CMOS checksum bad - run SETUP
    Mouse initialized

    Press <F1> to resume, <F2> to Setup

    When I press f1 or f2: Warning The CMOS checksum is invalid.
    Default values will be loaded (Continue)
    And I can go thru Main, Advanced Security Power set-up menus, the only
    thing I've done is change to todays time and date. It now asks if I want
    to save all set-up changes to CMOS. What do you think I should do?
  9. there will be an option to reset to fail safe defaults, select that, then save changes
  10. As I write, I am looking at the now working laptop!

    Your help is much appreciated!
  11. not a problem, glad to help
