Dell Latitude E6540 weird startup problem

[mr.Data]

When I start the laptop it works fine and boots until Dell logo and reading there is no drive in it. No bootable device found.

Then when I shut it down and restart it doesn't give a screen output. When re-seating the RAM it works for 1 time only.

Tried removing bios battery and resetting bios but nothing seems to work. This laptop only works 1 time everytime I re-seat the memory.

you should do more tests on this laptop (such as replacing RAM or reprogramming Bios) to find more clues.
