So I've done it. I am writing this from my recovered inspiron 15-7577 running the latest 1.5.0 BIOS

You might have noticed Several posters who appear to have the same problem -- basically that they have a brick after upgrading to the latest BIOS.

I really do think that it's likely that

1. What I did to fix my brick will in fact work for many (if not all) of the others' bricks; and

2. What I am about to suggest is not written in ANY of the documentation on "Emergency BIOS recovery" or the flash procedures. In fact, I didn't have to reflash anything, or to go back to a previous version of the BIOS.

I'm sure you rememeber my previous two mails..... Well, suddenly I realized that I had not in fact really properly reset the NVRAm. I had taken out the battery and the CMOS battery, but I didn't drain the residual power.

So all I had to do was reset the NVRAM, aka "clear the CMOS paramters."

If you go back and look at all the posters who have this problem, it becomes clear that all of them read very carefully the instructions about BIOS recovery, and reflashing etc etc. BUT NOWHERE in any of those pages does it state the obvious and helpful fact that after a BIOS upgrade, you need to reset the NVRAM.

It's even obvious why that's a good idea: the new BIOS might change the way it processes or uses certain BIOS parameters.

In fact, Dell *DOES* mention in the pages about resetting NVRAM that this can sometimes help with a NO POST/NO Video situation.

May I humbly suggest that Dell add a few lines to the documentation about BIOS recovery -- lines which explain that it can happen that users get stuck in a NO POST / NO VIDEO situation just after a BIOS update. This is nothing to panic about, but the fix is to thoroughly clear out NVRAM by removing the main battery, the CMOS battery, and then release residual ("flea") power by pressing the power button for a minute.
As far as I can tell, there are at least 5 posters who posses bricks of this sort right now, and one who unfortunately tried to resolder his BIOS chip, donig essentially nothing but costing him $1500.

I am exhausted from this effort, i must say, but i hope that it helps people. Please convey the suggested improvement in documetation to the powers that be.

Thanks!
