    I have recently aquired an e-system 3213 laptop however it has a BIOS password that i cannot seem to disable/reset.

    Ive pulled the battery and the cmos internal battery from the laptop 45minutes later, the password still resides.

    Does anyone have any idea how to solve this?

    Thanks in advance.

    I have to state sorry, i have to also enter a password just to load up the laptop, but i don't know either :S

    I think its looking like a replacement bios chip to solve the problem...but i probably wont be able to get a hold of one!

    Sad times.

    E-systems lock out everything but there are usually two solder points that you can short out.
    Basically you bridge the two points, turn on, wait for ten seconds, remove the bridge, and it'll then boot.
    The ones I've done were marked with either X or XX, or PJPx [the x is a digit]. There's loads of variations, and yes, it's a pain in the arse.

    Try removing the battery, removing the CMOS battery, then holding down the power button for 2 minutes. Worked for me quite nicely.

    Alternatively, get in touch with the manufacturer, and ask about BIOS password reset disks. See if they have any answers.

    Ive found a bunch of PJPx's and tried a few, but now i think the battery is dead!

    Now I'm weighing up wether it is worth buying a power adapter for what may be a fruitless endeavour!

    What are some of the details on the board? Do you have any idea whose BIOS code it is? You may be able to use a recovery option to overwrite the BIOS, and hopefully the password in NVRAM. The board may also have pads for a password clear jumper, but that will take some hunting.
    If the flash part uses the SPI interface, you might be able to program it in circuit (I think the odds of you finding a laptop with a socketed part are pretty low).
    Or there might be some sort of magic combination of things they techs can use. But the manufacturer is not likely to tell you anything unless you can prove the laptop is not stolen.
