I'm using a Dell Inspiron 1520. It was working fine until I mistakenly closed the lid and immediately opened it again during a general application installation. Then the laptop was not responding so I had to switch off by pressing and holding the power button for several seconds. The moment it went off the Battery indicator started to blinking in red. (4 Red blinks and 1 blue) and the QuickSet gives me a warning "Need to replace the battery" every time I restart.
I removed the battery and checked the status of it by pressing the test button and it lights up all the LED indicators fully. I'm positive that the batter is working fine. Is there anyway I can cancel these warning red blinks and messages? (Because its very disturbing to have a bright red light flashing next to the keyboard panel and the light even reflects in the ceiling at night - that bright!)
Thank you very much.
Welcome to the Community. To check the battery health using the charge gauge, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, less than 60 percent of the charge capacity remains and you should consider replacing the battery. Batteries just have a year warranty, anything over a year is a bonus.

Thanks Royan. In my case all the lights are appearing when I press the status button; so it's time to replace the battery. Thanks for your quick helpful answer.
