    Depends entirely on the make, in almost all cases the BIOS battery is a good old CR2025 or CR2032, the question is it it accessible under a easily removed cover/flap, and is it a regular battery or has the maker soldered leads and connectors on it.

    Cheaper the laptop more likely it uses a standard battery holder

    hello ! its a laptop , not a base PC , changing a bios battery in a laptop is not 5 mins and a couple of quid

    I can't agree, mine took around 5 minutes and I bought 2 batteries for about £4.

    Re: BIOS battery

    It can prevent a PC or Laptop from starting, when it's flat the default BIOS settings might not allow the laptop to start up until you enter the BIOS and prepare it for boot.
    Sometimes they also have a spaz because the system time has reset.

    However, on a 3yr old machine, especially a laptop (which is effectively always powered), the BIOS battery is very unlikely to have gone.

    The battery is ONLY in use when there is no alternate power supply for the BIOS. On a PC the battery failure is common when the PC is regularly disconnected from the mains supply.

    BIOS battery will not cause a PC or laptop to shutdown once it is running.... Not unless it goes faulty and shorts out the motherboard (but then your in serious trouble).

    a quote from my post earlier (page 1)


    "normally" , and I will use that word with caution , "if" a bios battery has failed , upon starting it invites you to press "F? etc" to enter setup. "

    Indeed.... And yet in posts following yours, this seems to have been ignored.....

    BIOS's can be strange beasts.

    Sometime a low battery may cause the time to slow down (or speed up) which can trigger the system to do a full POST check. I've seen BIOS batteries from the big names (such as panasonic) or no name Chinese specials, even on big brand boxes. You cant say that a battery will last xx years because you have no idea when the battery was installed, how long it was on a shelf before going into a PC, how long that PC sat on a shelf from build to sale and first power on. Its also entorely possible that the CMOS batter had a fauilt and stared off at half power, there we a bundle of Asus board shipped a few years ago with a batch of dodgy batteries that gave rise to a loads of issues, as no-one expected a new battery to fail that quickly.

    It could be the CMOS battery has shorted and is stopping the sysytem starting normally (even to the extent it wont boot at all). Generally if the CMOS battery is not showing 3V then it can cause issues and as I said its a cheap first stop fix.

    held down the power button for about 20 secs and it's come to life.

    I removed the battery then replaced it and was able to turn on my laptop at the first.

    This thread has been taken over with an argument about bios batteries, which is a random diagnosis that completely ignores the evidence provided by the op.
    Don't you dare criticise what you cannot understand
