Samsung ultrabook crashes when goes into sleep mode (lid close)

Hi

I still have the evil problem of my laptop dying when asleep. Sometimes the "kill" happens a few seconds after it entered sleep other times it lasts much longer.

I tried to send it in, but so far I was not able to convince anybody to replace it.
What tool could I use to show that the SSd is damaged? The windows tests do not indicate anything.

So you could not even convince Samsung to repair/replace it? I think you should be more aggressive. If it's a new system and it's under warranty, they are under obligation. If need be, report to the BBB.
