Dell Latitude e5470 won't turn on.

Are you seeing anything on the screen? I had similar symptoms on my Dell laptop due to a part broken hings placing strain on the GPU cable which disconnected the GPU cable.

Nope, nothing on screen. There isn't any activities happening on this computer, only power led is on.

remove the battery and try to start the laptop without it?

Tried it, the same behavior.

I think there again will be motherboard issues as all of the time with computers, which one day stops working.

Have you considered a broken disc?
I've never had Dell Latitude e5470 in my hands but if it's not too difficult try to (just temporarily) replace it.

Try replacing the CMOS button battery but it might be hard to access

Yes, already checked where CMOS placed. All computer should be disassembled. For now, we put it back to warehouse. When will have more free time, will try to replace CMOS battery.
Thanks for suggestions, will close this thread now.

Missed Your post. Tried to disconnect drive and start computer - no difference.
