My Laptop Battery is messed up?

Ok so my laptop battery won't work i need to plugin my laptop i've tried battery saver apps on pc software i've drained the battery I've charged the battery i'v don all the power saver options but still nothing, the battery can't just be worn out cause i got this laptop last year it's a Lenovo not sure what model but i picked it up for about 300 bucks when i plug it in it says 93% of battery is available but it's dead

Sometimes there's a BIOS setting that deals with calibrating the battery.
If the laptop is less than a year then call Lenovo.

If you turned off your computer and removed the battery, the "drain" doesn't do anything… That's a stupid little myth, since nothing is operating. It's best if you bought a new one, I think it's the battery itself.
