I was just installing ubuntu on my new samsung chronos 7 NP700Z3C, the laptop was stucked at booting ubuntu so I pushed shutdown button for 5 seconds and turned it off. Now it does not boot. It just starts but the screen is blank, keyboard seems dead (only the power light is on). I hear the cd start spinning when I start the laptop but I can not eject it and nothing happens afterwards.

My changes: Repartitioning. Disabling fast boot. Changing boot order to boot from CD & USB first. Installing ubuntu.

I wonder if is there any solution to make it boot?

Your motherboard is now dead and needs to be replaced.

There is a bug with Samsung UEFI (similar to BIOS) that means that Linux can completely brick the mobo.

How to destroy a brand-new Samsung laptop: Boot Linux on it - The Register

I really wish the news were better but I cannot find any information on how to fix one of these bricked motherboards.

Just to clarify, this is a Samsung UEFI bug and not a Linux one. Samsung laptop bug is not Linux specific

+1 This has been resolved in the upstream development kernel but it will take some time for this fix to land in distributions; fall back to using the BIOS by enabling the Compatibility Support Module on Samsung laptops for now, after you took it through RMA. –  Tom Wijsman Feb 10 '13 at 22:27

That was the easiest laptop death that I have ever seen. Thanks for the info. –  Mehdi Sadeghi Feb 10 '13 at 22:53

"Your motherboard is now dead and needs to be replaced"

That's not entirely true. Although it's a pain to actually split the case on the Chronos 7, it can be done. From there the battery CAN be disconnected from the motherboard for a couple of minutes which will actually clear BIOS to default. I know, I've done it.

Hope this helps.

I like to try but now I have another laptop. But it is amazing that you have done it! –  Mehdi Sadeghi Oct 26 '13 at 18:26
