  • Lithium Battery

    Do some laptops avoid the need to use such as a Lithium Battery to store CMOS settings such as the time and date?

    I have an old Twinhead Notebook that fails to retain the time and date. I am wondering if it is because of course due to its age the main battery no longer holds any charge. I managed to remove some of the panels underneath the laptop, but cannot see any sign a Lithium Battery.

    Are you refering to the CR2032 coin battery that normally trickle feeds power to the CMOS chip to hold the BIOS settings? The only Twinhead I worked on had such a coin battery and could be replaced but from memory it took some time to dismantle and find the little sucker.
    1 1 was a racehorse.
    2 2 was 1 2.
    1 1 1 1 race 1 day,
    2 2 1 1 2

      Yes the little coin battery.

      A pal of mine who is good at fathoming out modern gadgets has taken it. He just repaired a Wireless bell where he had to unscrew 2 bolts just to replace the coin battery.

        To be fair, a laptop has a bit more internal hardware, and needs to be somewhat more robust than a wireless doorbell

        Have you tried as there are often on-line documents or videos on dismantling almost any type of laptop
