I am having a terrible problem with my 4-month-old Latitude laptop. Without any determinable cause, the battery light (below my screen) has been blinking red 4 times and then green once, repeating constantly whenever the power cord is plugged in. I have to use the power cable to use my laptop at all -- if the power cable is not plugged in, then my laptop is dead. I have tried two different batteries, both of which are charged and should work fine, but they have given the exact same response. The laptop does not seem to recognize my battery at all. Can anyone help me figure out how to use my laptop without the power cord? Thanks!!!
Thank you for using the Dell Community Forum.
The battery lights should only illuminate in a green color. If any other color appears, it may indicate that the battery or charging system is defective. You may wish to look at the battery troubleshooting ideas posted in the Power Management FAQ.
I have the same problem too. I have a D500 and tried upgrading the BIOS but the problem still. I dont´n know what to do!! Maybe it´s a problem design. How to use my laptop without the power cord? FAQ doesn´t means anything.
HELP ME PLEASE BOB!!
