My mini laptop will not start without the charging cord. When it is on with power cord, it turns right off when i take off cord

you just bought it ? or its an old one

bout 2 years old

Since its only working with the power cord plugged into a wall outlit...Sounds like ur battery is not hold a charge

A replacement should fix it

This,

a good idea also is to remove your battery when using your laptop at home when its plugged in. They seem to retain their "life" a decent bit longer in my experience

hope that helps , somehow

now that your battery does not charge or hold any power, you can simply take it off, it makes the laptop lighter to carry.

The battery in your laptop needs to be replaced kind person; This happens naturally over time as laptop batteries have an approximate 3 to 5 year life span, but sometimes less due to how much the laptop is being used or how it has been treated. Good luck.
