    Hi all,


    my Toshiba A300 i think needs a new CMOS battery as I am unable to boot Windows / quite often cannot access BIOS Screen and am getting a PXE-E61 no Boot error.

    Apparantly its soldered to the MB but I dont know which type it is - both pins on 1 side or 1 on both sides. I think its a ML1220 but not sure, i think from what I seen on the Web its same as the A200. Am I right in saying ML means its rechargable? RS Components have CMOS battery marked up with VL....they are about 5 euro plus P&P - can I use the VL version? The existing CMOS is about 15 years, rarely used for about 50% of its age.

    Is it worth a punt for less than a tenner plus installation cost (how much would that be?). It has a new battery and a cheap SSD for a possible Windows 11 via Unsupported method install.


    Cheers

    I think both are rechargeable and same voltage - but Id stick to the same one as you have. Watch out for the soldertag legs - there are lots of variations.

    Do not use the non rechargeable type - it likely will cause the battery to leak.

    If you are not in a rush - they have them on Aliexpress for two euros.

    eg.

    You ask for installation - if you want do it yourself - It might be easier though for you to go with this style though -

    You could just bend off the existing one - leaving some wires poking up - and either clip or solder on the battery with the wires above - red wire to positive.

    It might even be enough to just remove the dead battery - and the laptop might be usable.
