Precision 7530 & Precision 7730 owner's thread

The alterations to audio you're hearing with the realtek drivers is the audio enhancements with the maxxaudio app. You can disable this by opening the MaxxAudioPro app and going to the Playback tab and disabling enhancements witih the slider. The exact same thing happens to me if I don't turn it off. With it off it works 100% fine.

 

The testing i've done with windows performance toolkit has indicated its likely to be a dell related driver, not a windows one. I've sent all the results I've gotten to dells support and I'm hoping to hear back from them about it soon.

 

In which case we'd have to perform a clean install, ensure network connectivity is disabled, and build up the driver base one by one and test latency. After which we'd determine precisely which driver is causing said issue.

 

Unfortunately this may be the only way for us to figure it out ourselves.

I did some similar testing by booting into diagnostic startup and progressively re-enabling services to see which one was causing the worst interrupts, but ACPI.sys was still doing the same 2-3ms interrupts for me regardless of whether I was in safe mode, diagnostic startup, or regular startup. A full clean reinstall and progressive reinstall of all the drivers until the ACPI.sys issue starts up again is pretty much the only way we could figure out the culprit at this point.

 

I agree with You but if I turn off this slider I disable the equlizer and other enhancments and then the sound is like from 1999 years laptop so for me totaly not to accept.

 

Hi everyone, I have a 7530 and am wondering what board does the keyboard plug into, is it the actual motherboard or does it have a junction circuit board under the palm rest? Don't laugh but reason I'm asking is I was unfamiliar with the procedure of disconnecting the cables and I managed to damage two connectors the second day I had my new laptop. I did review the instructions from Dell and watched the Asia travel channel video on Youtube but it wasn't clear enough for me I guess. Luckily I only lost my keyboard lights and the mouse button in the keyboard so it's not mission critical.

 

Plugs into a circuit board, which then plugs into the motherboard.

You're in luck: you can replace the palm rest assembly, and your keyboard lights should be fine. Just file it under accidental damage and ask ProSupport to get a technician to fix it up for you. Ideally observe what he/she/they do, and then you can perform surgery yourself.

 

Thanks for your help and quick reply, I was just reviewing this https://www.laptopmain.com/dell-precision-7530-disassembly/ and it clearly shows the junction circuit board in the 7th picture. I called Dell yesterday and the guy I spoke with told me I would need a whole new motherboard! He would have sold me the wrong part for who knows how much. I've built a few desktop PC's so I'm not afraid of surgery I just thought they were push on connectors and didn't realize how the unlock mechanism worked. Do you really think they'll do the accidental damage repair?

 

Is there a trick to getting the back cover off without breaking off the plastic snap joints? I managed to break about 4 of them when I installed my drives.

 

It's quite likely, mostly it depends on who you get, but in my experience they cover just about everything. I've even heard stories of them covering damage due to bad liquid metal applications...
