Laptop battery dies after laptop shuts down

[Chris76]

Wondering why my laptop battery dies when computer is sut down. My battery is fully charged then when i shut down the computer the battery dies. I go to turn on computer and it says battery is crticlally low and won't boot unless you hit f10 or f2 for setup.

It might not necessarily be dying after a shutdown, as so much as the laptop's bios reads the battery as being close to the end of its life. If you don't see any issues with battery life, then it is not something to worry about, but this is usually indicative that your battery is not operating within normal parameters and will die soon.

How old is the laptop?

how long will laptop stay on with just battery power before it warns you to connect to external power?
