You are too king to us what we already know. Problem is not how to fix it but how to prevent it from happening. You know, the problem is that after you remove your AC adapter it all goes to <ADMIN NOTE: Substitute character removed as per TOU> again.
Dell haven't fixed the problem so far. I went through this with their terrible support a few months ago. At the end they just offered me a refund for the laptop. Claiming they would use my model to research the error.
They don't take customer feedback at all. A simple explanation of our problem and still they have no means to escalate it.
Don't waste your time trying to get Dell to fix it, either install the custom bios I posted that fixes the problem, or cope with the error. Trust me, I worked in support and Dell don't have the means to fix these kind of problems. They are not interested.
I'm only speaking from experience, because I know it will never be fixed.
This would have been awesome two years ago. I'm going to wait for any reports of bugs or bricked laptops before installing it. I have already moved on to a different laptop but still have the 7720 around, I'll give it a shot if there is no bad news.
Edit: Ok well I figured that since I already have a new laptop I will be a guinea pig. If there are any issues I will report them in the forum.
Can confirm boost is now working correctly. I attempted an overclock to a GPU core freq of 850 MHz and when disconnecting the power it drops to 745 and then bounces right back up to 850 when reconnected.
Thanks clear abf..... wow, that's amazing news and something I would never had expected Dell to fix given that the laptop launched 3 years ago. I wonder what the story was behind the fix and why its suddenly arriving now.
Dell really need to describe their fixes to a a finer degree though given the importance of the issue for at least some of us. "Optimized GPU performance" doesnt really cut it, especially when its coming under the "Enhancements" section and not "Fixed". I wonder if they even realise what they have fixed in this case.
Edit: Have installed A17 and confirm GPU bug appears to be fixed on my 7720 as well. Awesome.
I've been using a modified bios for a long time that slightly ocs the card and fixed the boost issue. It was a problem with the gpu bios and Dell failed to recognise, let alone fix the issue. Now there is a fix? After so long? Why did they even bother?
I bet the throttling CPU issue on battery still exists.
Was the throttling CPU bug the one where you could fix it by setting to 99% CPU or something? I found your old message about it but no response from Dell it seems.
Im wondering if the GPU bug existed on another more recent Dell system as well and it was something they were able to fix and the 7720 just came along for the ride. Either that or perhaps they were pushed by someone or a group of people to legally be bound to fix the issue. Either way, its nice to finally see a fix even if it is 3 years on. My 7720 still has much life left in it yet.
It most likely was because of another laptop. Nvidia keep recycling the same gpus under different names anyway, i know from when i bought my 7720 i found the 650m was the same exactly as the 760m and i bet there's also a8 series variant too.
As for the throttling problem, I'm not sure out even is a bug. Running a game on integrated graphics using battery meant the cpu ran fine, up to it's boost speed.
Do the same with the dedicated graphics card and it was apparent the CPU didn't realise it was needed by games because it would throttle down to 0.3ghz, sometimes 0.1. It made games unplayable on battery.
Even without gaming, running on battery the CPU will throttle now making the laptop noticeably slower.
I always thought you could control this using the power management feature in Windows but it never worked.
I was in contact with Dell about both problems for a good while and they wanted my laptop back to have a look at the issue's but i refused in the end because for the same money they were unable to offer me a replacement laptop of the same performance. I got a good price apparently because to get the equivalent specs on a later model they wanted me to pay more. Terrible terrible experience and i will never buy Dell again.

In case anyone's still interested, Dell today posted a new BIOS - A17
Fixed
- N/A
Enhancements
- Optimized GPU performance
The GPU boost seems to be working fine now, boost comes on as soon as power cable is reconnected.

Finally after 3 years, DELL decided to give a solution to a well known issue. Better later than never...
