Starting last night, my Latitude E6500 will not boot. On pressing the button, the CPU light sometimes blinks for just an instant, but never for long. After that, I hear the fan running for a few seconds while the power light remains on, but nothing is on the screen whatsoever. Then, the fan stops, the power light goes off, and I am left with solid Caps and Scroll lock lights and a flashing Numlock light. This lasts for about 30 seconds or so, and then also goes off, leaving the computer completely off. I was able to successfully charge the computer (it had a half charge when this started), and it now has a full charge. What could be wrong? Thank you.
Maybe battery is no good. Have you tried to use this computer using AC adapter? Otherwise sounds like a hardware defect. You could try re-seating the memory:
But that's all I know.
I have the same problem. It is intermittent - sometimes this will go on for many minutes and sometimes briefly. Eventually, one of the times I hit the power button, it starts. Any solutions?
I have got your same problem.
I read somewhere that the problem is the cpu not detected.
So I think the problem is the mb.
I contact dell the ask me about 600€ for mb change, I expired warranty few months ago.
So I think will buy a new laptop soon.
