Precision 7530 & Precision 7730 owner's thread

Space bar works on every spot on my 7730, which I expect to use the same keyboard as 7530. So maybe you should call Dell support to replace the keyboard.

 

7530 here. I can hit the space bar anywhere and it registers. I suggest that you just contact Dell and have them replace the keyboard.

 

I've run it twice and result was "acpi.sys". Thank to Google I've found a problem related to "acpi.sys" and "wdf01000.sys" (same as mine):

Latest Dell drivers are installed, so I've no idea what I should look for.

 

On my 7530, acpi.sys is the biggest offender but the latency is still under 2ms. I haven't been able to discern any audio skips or buzzes. Are you getting higher than 2ms latency from acpi.sys? (Here I am referring to the "highest execution" on the "drivers" tab in LatencyMon.)
(I was fighting with audio issues on my M6700 for a while, where I was getting latency spikes of over 20ms... It was related to the Wi-Fi driver in the end.)

 

To everyone experiencing the dock power issue (system sometimes cannot draw power from the Thunderbolt dock), Dell sent over a workaround today, which is working for me.

The workaround is simple: go to the BIOS and turn off USB PowerShare (under "System Configuration").
Try it and let me know how it goes.

 

I received and installed the replacement 97 Wh battery. It's not a refurbished one as they said it would say on it, it's completely brand new and has 3.9% wear. Oh well, guess that is better than 5% wear.

 

One the 7530/7330 are people finding that the fan speeds are far too aggressive, even when setting Thermal Management to Quiet in Dell Power Manager?

When my CPU is at 41 deg C with minimal utilization the fans can sometimes continue to run at almost 3900 RPM, which I don't get at all. They should totally be off or minimal in this situation.

 

I'm getting 2.34ms latency from acpi.sys. First time I heard audio stuttering is on Windows logon. The issue is reproduced each time error/alert/information message appears in Windows, or when sound is played in Edge or VLC, or when I use software like FL Studio.

 

Eh, don't use "Quiet", use "Optimal" or whatever the top one is... It is actually quieter than "Quiet" I find.

 

I've tried both actually and still I think the fan speeds are too aggressive. I'm pretty certain the CPU can cool passively or with 2000 RPM fans when it's between 40-50 deg C and minimal utilization.
