Why does my laptop screen go black when the charging cable comes out at times??

Sometimes when the charging cable gets unplugged accidentally the screen goes black. What causes this and what can I do to fix it???

Its sounds like a battery issue, may be could be a voltage problem.

Check your power management scheme. It sounds like it is set to shut the monitor down if on battery and it goes below a certain power\charged level. Does it happen as soon as it becomes unplugged or after a short period of time of it being unplugged?

Agree with the above. Check your power management menu option selections. I had a laptop that had a charge circuit failure and my battery became completely discharged. If I pulled the cord, there was no backup power and the unit just shut off completely.

Its plugged in and fully charged. It happens sometimes even when its a bit unplugged. I ordered a new battery for my laptop off of Amazon for 50 bucks so I don't have to pay over 120 bucks for it from the Dell site.
