Charger blink pattern

Question

Laptop will not start with or without charger. When the power button is pressed it lights for about a second and goes off and the charge light blinks once. I suspect the charger but don't have another one that fits. It is putting out 19.6 and 4.5V measured with a meter but that is at no load.

I removed battery and held power button for 30 seconds, re-installed. No change.

Charge indicator blinks 1 second, 1/2 second, then about 1/8 second. Waits and repeats. Is there a list of blink patterns available.

Laptop has been powered off and power disconnected for 6 months.

Thanks,

JH

Thanks all. It turned out to be the power brick.

Latitude E6520. Sorry, thought that was covered as it was required to create the post. But I see now it is not displayed.

In order to point you toward the meaning of the LED pattern, you will need to supply the system model - Latitude E5320, 7240, etc.

Not sure what happened to thread but some responses cannot be seen now, in particular the one about the battery slice.

Thanks but I do not have a slice. The pattern I am seeing is on the battery symbol LED and it does not match anything in this list.

Any further suggested actions?
