“Your battery has experienced permanent failure and needs to be replaced”
This message will appear in the BIOS and also on your system notification if you are able to successfully boot. You will probably get this error message sometime in your laptop usage time whether you are using an XPS alienware HP and so on.
Basically it means your laptop battery is dead!
You need to buy a new one. You can get a new battery on this link.
But wait, not so fast, first lets make sure the battery really is dead and needs to be replaced or its just the hardware acting up.
There are couple of things that can cause the computer to show the error “Your battery has experienced permanent failure and needs to be replaced” whilst the battery is fine and its just a system error
Please note if you are connected to a power supply the laptop might boot successfully. Even if you skip the error messages, but that might cause you even further problems. For instance the battery can explode, leak or expand affecting other parts of the computer damaging other parts.
First, lets generate a battery report if you are able to boot without the battery. This will give us a tonne of information about the battery and the its status then we can go to to the steps to check if the battery is dead.
Generate battery report in windows
Go to the Command Prompt (CMD) and type “powercfg /batteryreport” without the quotes and hit enter. You’ll get message with the directory where the battery report is saved usually in “C:/users/yourcomputerName/battery-report.html”. Double click the file, it should open in your browser.
Go through the document and see if the logged times correlate with the actual battery usage.
How to check if laptop battery needs to be replaced.
1. Cleaning and reseating the battery
Shutdown the computer, remove the battery. With a soft cloth clean the terminals and the connectors to the motherboard. Put the battery back and attempt to charge it. An amber or red light on the led light means a problem. In that case the battery would no have been fixed.Also check your cables, the charger and the socket in which its plugged into. If you have a different charger of the same model try charging with it.
2. Flea power
Second check if flea is not the cause of battery permanent failure error. Flea power is the residual electricity remaining after a computer has been shutdown and disconnected from the power source. This can also affect proper functioning of the computer. You can read more about flea power here. To clear flea power, remove the battery and disconnect from the power source.

This alter the functioning of the computer management system. Some work fine but remove any if have it installed. Shut down the laptop remove the battery and repeat step 2. Now put it back and see if there is any change.
4. Dell ePSA

You can run tests on individual parts of the laptop. Select the battery test and run the test to check for errors. If the battery is dead you will definitely get errors. If you do get errors search for the error code that will be shown.
