    Hi,

    All of a sudden my laptop battery seems to be draining very quickly.

    From fully charged to dead in 20-30 mins. It also seems to charge 'fully' in a very short time.

    Is there some sort of process running things down or is the battery just too old and worn out?

    Im running Windows 10 64 bit. Toshiba Satellite L775.

    I did the attached battery diagnostic via commad prompt if this helps...

    Any advice, much appreciated.

    Thanks

    The report says the battery charges to about 18% of it's capacity when new, so it's nearly worn out. This is consistent with the behaviour you mentioned. Unfortunately the only cure is a new battery.

    Thanks managed. Seems odd that performance literally dropped off overnight though. Could that signify anything else, virus or something?

    It originally came with Windows 7 Home Premium 64-bit.

    There are several places on-line that you can buy a replacement battery.

    Maybe this might help:

    That is odd. Is it possible it was getting worse more slowly but you didn't notice until now ?
    If it only charges to 18% there's not much you can do but try leaving it switched off but with the charger plugged in overnight to see if charges more than 18% then.

    Yep I tried that last night. I'm stumped. If the battery is just worn out and needs replacing fair enough, just suspicious that it dropped off so fast.

    how old is the battery? If it's the original, it's cooked. They are just a chemical reaction, after all. You could try letting it totally discharge and then recharging it, but IMO, it's time for a new one. I've an old vista laptop that if I don't keep plugged in on the desk dies in about 20 minutes flat. I've just not gotten around to getting a new battery.

    When you get a new battery make sure that you condition it properly.

    I do recommend several cycles, but after the first one as in that article the following ones can be just normal use without the mains. Heat is the biggest destroyer of batteries so a slow discharge/recharge is better than a rapid one that generates a higher temperature.

    Many people say this is not needed with new batteries nowadays, but it does make a difference to the life of the battery and the life of the battery (sic)
