i have a small dell latitude e6400. when i power it on it stays on for a few seconds it shows 3 led locks lit up on the keybord then shuts down.
The Dell Latitude E6400 was Dell's mainstream corporate 14.1" notebook introduced in August 2008.
Hi @sugerbea ,
I realize that it may be difficult but can you tell exactly which ones blink and which ones are steady, looking from left to right.
Getting that information will help diagnose the problem as the sequence of which is flashing and which is on steady gives an error code which will help to point out the problem area.
