At least you had everything in your list - Windows Boot Manager being what's really needed.
AS to change boot mode
Actually you should leave that set to UEFI Boot Mode, Secure Boot On unless you plan on installing another OS to boot from like say Linux.
Edit: and yes these new BIOS seem to carry over settings from one to the next, so once your hit with something it sticks going forward.
look at my past posts on this thread for the link to the other long thread about 17R SE 7720 Lost BIOS Access - tons of information in there from everyone effected with this crazy BIOS.
So has anyone ran into this. I did an ePSA test while on A12 no problems at all. I updated to A13 ran an ePSA and received the following video memory discrepancy error.
I really hope a tech does not need to replace the mobo or anything, the last tech I had came over for my old 7720 attacked it like he was a wild ape, case was all bent and scratched after, bezel was not flush, it was a mess.
I've only owned this laptop for 3 days and have spent those three days researching and looking for a fix. I have decided to return it and get a refund. I am not going to keep a product that has features that doesn't even work.
I was planning the same thing, but i decided to keep it.. This ignorance and overall quality of the support service is certainly a huge deal breaker for me in future for sure... I hope someone in charge will notice that the only purpose of support here is copy&paste answers to very simple and common questions... I understand these guys are probably very cheap, but they are ruining this company reputation.....
They don´t even bother to write what was changed in last bios update....
It´s not this issue alone which is actually bothering me... but the overall attitude, meaningless, ignorance, lacking of knowledge of support staff here is something, why i regret i bought this laptop for the first place...
>I apologize for jumping the gun a little bit here folks; I was originally told that the bios rev to correct the BIOS issues >would come out in April sometime. The good news is that engineering is working on A14 and ETA is in April / May. >A14 should have fixes to correct most if not all of the reported boot issues.
I found that sometimes the FAN is being stucked on lowest RPM no matter how high the temperature is.. It´s not going turn itself off... It´s pretty annoying to hear the sound of the FAN, when the temperature is below 30c. Have anyone encounter that?
I think the fan issue is related to the Nvidia drivers. It seemed to work fine with 310.92 drivers, but then i began to notice the fan not working properly when i updated to 314.22
Regarding A13 BIOS and what exactly has changed, I do know for sure that DELL fixed a problem with the 7720 failing to wake up from sleep with the lid closed when triggered by an external USB keyboard or mouse. This was important for me as I use it with the lid closed and connected to an external monitor and keyboard. This was in response to customer feedback at en.community.dell.com/.../19479193.aspx , I think the fix took about 3-4 months from first notification in that thread.
Why DELL does'nt mention what has been fixed in its BIOS updates is a bit of a mystery. Perhaps its company policy not to comment on past failures in case it comes back to bite them.
Regarding the GPU Boost issue, I have found that by propping up the rear of my laptop by about 1 inch with a small bock of wood (don't block the inlets), I have been able to reduce GPU temp under load by about 5-7 degrees C. This might help you guys to increase the time it takes before the boost mode is disabled. Lets hope that Dell is working on it behind the scenes though, but the lack of a DELL statement in this thread is a worry.

Rafterman, Looks like you have a problem with memory integrity. I hope you will not have to send your laptop to Dell Support.
On my side. Curious event this morning. At startup, the startup F12 has reappeared ...
I started the diagnostic software. I will see the result when I get back at home tonight.
Do you think 7720 is alive and has feelings?! This would explain all these random problem ;-)

I'm sorry not good at English. (Written in translation tools)
Are there any plans to fix boost lock bug DELL?
If they do not plan it, Should profess that they do not fix

Hi,
I confirm that I have also found that the FAN works much more than before.

Other threads. Write support.
Little hope of A14 ....

johnnyxo: It´s really hard to believe, that it could be caused by nvidia drivers only, but i give it a try, thx for the suggestion;-)

I ask Terry, if other issues will be fixed as well in next BIOS update. We can only hope.
