Config warning going off, at FL200. The horn. BEEP BEEP BEEP! It dosen't say whats wrong? On the displays. The Landing alt iis blanked out on presurisation panel. It is set to Auto which I think is right. Is this the problem? And a amber light saying auto fail. Am I dieing of hypoxia? It is anoying Arrrhhhh! any way of turning it off?

Its the cabin pressurization warning. Check that the pressurization panel is configured correctly.

no lights on the overhead on? check failures on the FMC. I had cabin pressure loss twice, first time I could not recover and second time I followed QRH.

ok better get down to 10000f Ok will check. I don't remeber setting this fallure.

I had a pressurisation problem today as well. ALTN wasn't working either so I had to revert to MAN mode until cruise altitude and then it somehow fixed itself and I could reactivate it. In the time before I noticed the issue, the pressure differential had red-lined :)

well im below 10000f and the horn is off. So somthing went wrong with pressure.

Did you set your cruise altitude on the pressurization panel?

[DAD 2,653]

I always do now since my experience, won't forget that anymore ;-)

Probably I need to read up on this, before taking off.

Did you set your cruise altitude on the pressurization panel?

Yes I set it to 20000f and the landing alt to 350f. I was landing EGCC. But at the time of the error those figure looked like they were just dashes. And a amber auto fail light was on.

Are your bleeds on? Are the Iso valve and packs to Auto ? Check your after start switch setup It caught me out too.

It could be that. I got distracted at that time with the chocks issue, after push and start. So that would make sense.
