    Hi. My old laptop Dell Latitude E5410 was stuck.

    After hard power cycle its lights CapsLock and ScrollLock On and NumLock blinking.

    Google say that i's a CPU or MB issue.

    I reinstall and then change CPU but nothing happens. Then I disconnect all devices. And then completely disassemble notebook.

    I connect just Display to MB and try to power on. Same result, NumLock blinking.

    After that I disconnect display and connect monitor via VGA. And it starts!

    I try to disconnect cable from display on display-side. Notebook starts succesfully. It means that cable is OK.

    I think smth in display chip was broken. Maybe static electricity, maybe it's too old.

    Now I write from this notebook.

    If Numlock is blinking - try to replace display too.
