You wrote that BIOS 204 also has some trouble with your SSD.
I re-read the first post, and you sometimes have to take out the SSD to get into BIOS setup.
And sometimes the screen stays black when the SSD is attached.
So it is not working. Let's see if I can find something...

EDIT: I took a quick loot at BIOS 204 and 218 and here is what I found:
- there are MISC.SIG modules in both BIOS versions
- sadly they are 100% identical
- the issue must be in the main BIOS code, boot block, whatever (not in the MISC.SIG)

Yes, and as I touched, I do not know if the problem is hardware. The only thing I therefore can do to start with is to try to update the bios to the newest, but where it works with SSD.

The SSD has been tested on three other laptop and a desktop without problems, this with the bios integrate it. Have not be able to update the firmware as it is not connected in AHCI mode. EDIT (Just remembered that attempt to update the firmware was on another laptop so did not attempt it on this one )

Yes it may well be that it is in the bios code, but can only take it as if there are "flaws" in the Satacontroller, and when it does not recognize the handshake in 218 it therefore sends/jump the thread over and requires HDD password. The SSD name in the bios (218) appears with strange characters, spaces and line feeds, which may be the reason that there is an error in bios code, but it can also be security or made deliberately by Asus?

The first time he came with the the laptop it was because he could not get it to turn on, it means that it could, but it was with a black screen. Took the HDD out and found out there was something wrong with it, very unstable. It was the HDD as the laptop was purchased with from new.

I put this SSD in and had to downgrade bios before it would approve it. Everything worked and he got it back, and I ordered a faster CPU for it. After a month's time I put the new CPU in and everything was ok, a few days after he again could not boot it. Played a little in bios and tried to explore different things among others also with other HDD and SSD in another machine. Do not know what, but it started to work again, the last thing I tried after which it again started, was to turn fansystart off and also switched to IDE, but after it again would boot, I could again turn fansystart on and switch to AHCI (perhaps just a coincidence). So as with electronics with loose connection, there is not much I can do, better that nothing works then this.

Promised to give feedback, but decided to wait until there are problems with it again, foolish to do more if there are no more problems even though I wanted to know whether it worked as it should

Now the problem was back.

At first I wanted to try to read the Winbond chip directly, which I could not, oddly, tends not to be a problem reading it while is sitting on the board, where writing for the most part requires it to be soldered out. So had to solder it out, but having to do that every time, now I was going to experiment, would not be good, so chose to put a socket on the board so I could get to chip without having to disassemble it every time.

Change the backup battery and updated the SSD firmware at the same time. Perhaps solved part of the problem?

Tried with the bios I MOD last time, but did not help. Tried to replace different modules in the BIOS, but now the problem is something else, perhaps because I have updated the SSD firmware?

Have loaded the latest version bios in and it starts, and to finds also the SSD, which it had difficulties last and can also get it to boot up and load windows  without problems, but now the problem is that as soon as I turn FancyStart on, then it appears with HDD password, which is a little weird, because when I turn to the laptop then it shows first the images that are setup in FancyStart, which requires that the BIOS have connected to the HDD/SSD, but when it needs to load windows then it jumps and ask for HDD password. Weird

For now I have turned off FancyStart, so I have to see if the problem reappears when he has used it for a long time.
