I have a Dell Inspiron 6000 (about 3-4 years old). Yesterday my power light started flashing......4 orange flashes followed by 1 green flash.....and it keeps repeating. It flashes in this fashion whether I have it plugged into an A/C power source, or if I am running strictly off the battery. When plugged into the A/C power source the battery recharges up to a level of 99%. I have also tried removing the battery and putting it back in and the problem still exists. What is causing this? Is it anything serious? I certainly hope not.
For now, if your Dell Inspiron 6000 is in working condition I wouldn't worry too much about the flashing light. However, if it currently does not work then, I suggest you either phone customer service, or if it's still in warranty get a replacement.
