    hello:

    I "inherited" an NEC Versa laptop, model 4230. We finally got it up and running but I think we need to replace the CMOS button battery (I get a "System battery is dead" error message). I have the right size/current/voltage battery but cannot access the board. I realize I may have to solder leads on the battery to secure it properly to the board. Is there a special NEC tool to take this cartridge/mother board out? There is a lock/unlock icon next to a small hole of this cartridge. All of the other cartridges do not have this oval shaped hole. What shape is the tool? How can I change my battery w/out getting to this board?

    Thanks in advance,
    PamK in San Jose, CA

    The "lock/unlock" symbol next to an "oval hole" sounds very much like the standard Kensington Lock provision on a laptop.

    This is for attaching a locking cable to lock the PC to a desk, and prevent theft. Its not a lock to get access internally for the laptop.

    The "system battery" will be the little button cell or similar that is located on the motherboard of the laptop, probably deep within the internals.

    Taking a laptop apart (and getting it back together) without damaging the laptop can be a complex and difficult operation, and you really need the full service manual to find out how its done for that model. I would suggest taking it to a shop.
