I am getting the opposite to most people. My laptop will run fine without the plug-in. It will charge with the plug in. But when I try and use the plug-in and run my laptop (for better light and longer use) it turns my screen black. If I disconnect the plug-in battery and close the lid on the laptop, my screen will come back and I am good to go. Can someone help me.

If your laptop works fine while plugged in but stops
working while unplugged it's likely that either your laptop battery is
bad or your laptop is not charging the battery properly.
Make sure the computer has been charging from the power plug for at least two hours before attempting to unplug it.
In some situations the battery can become loose. Removing it and then put it back into the laptop.
To remove the battery slide this switch to the opposite side and hold it
in that position until the battery is removed. When doing this with
some laptops the battery will pop out and allow you to grab onto it.
Others will release the latch and require you to grab onto the battery
usually with the tips of your fingers and pull it out.
In most cases this will help, but if the problem persist you may have to get a new battery for your laptop.
If the power supply does not run the laptop without the battery, then the problem is the jack in the laptop, over time the plug breaks free of the motherboard causing intermittent operation or no power. If the power supply runs the laptop without the battery, it is the charging circuits on the motherboard that is the issue.
Try letting the computer sit without the battery for a few minutes, and also without external power. Then try plugging in your external power WITHOUT the battery and try to start it up. If it does, add the battery while it is running. Then try it with the battery only.
take out the battery and try to start the computer with it plugged in using the power lead. If this owkrs without the battery being in then the power lead is fine.
If this doesnt work it could possibly be the power lead or the power supply inside the laptop. Does the power lead converter (the black box half way down the lead) get warm when plugged in for a while, if so the power supply is probably the fault
If you plug the charger into the computer without the battery and the laptop runs fine, then I would suggest to you that your battery is failing and will no longer accept the charge. On the other hand if the laptop will not stay running or acts strage and the screen dims and gets bright, then I would suggest to you that the charger's built in voltage regulator is failing and will damage the laptop if it continued to be used. A bad charger will also permenently destroy the battery condition.
It doesn't look to me that you're doing anything wrong there. Was there a specific installation requirement for the battery?
I recently changed my battery on my IBM/Lenovo and all that was necessary, was to let it charge fully before usage.
If you say your battery was charged for "a few days", then I assume there is something wrong with the battery. Next to your taskbar you should see a battery symbol. Double-click on it and you should see the Thinkpad Power Manager. If there is a tab called "Battery Information", see if that gives you more details. Look at the Manufacturing date!
If you really can't run the laptop without being connected to a power source, I would definitely return the battery or at least call the vendor. If your computer is running fine otherwise, there should be nothing wrong with the machine itself.
If you can take a screenshot of that battery information window adn post it here, I am happy to look at it.
PS: You're doing the right things when you try to use the laptop without an external power source - that's the whole idea, isn't it?
