Hello all. Wondering if anyone else is having strange problems with a brand new 7670?
Here is what is going on with mine. Dell support case opened, but they are not grasping what I am saying!
1:
Humming / Fuzzing type noise through laptop speakers. (all the time, even when external audio is active using Ultrasharp U3421WE monitor audio).
Humming / Fuzzing type noise from under keyboard. (Coil whine?)
Occurs when mouse is moved, when graphical elements of Windows UI appear on screen such as opening a window. & when graphics load is high such as 3d application use.
2:
Laptop in sleep mode for less than 1 hour. Humming/purring noise coming from laptop speakers.
Spacebar pressed to wake laptop up. Fans came on at mid rpm for around 2 minutes, laptop did not wake up.
After around 2 minutes laptop reboots by itself and goes into Windows blue recovery mode.
Startup repair selected, laptop reboots and stalls at Dell bios full screen logo.
Laptop powered off (power button 10 sec).
Powered back on, left at Dell logo for around 10 minutes, at which point Windows loads.
No events in Windows Event viewer regarding this - it has a time gap in the logs when this occurred.,
3:
Laptop display screen. (4k Old)
Screen randomly changes to intense brightness/contrast/over-saturation.
Has occurred multiple times, and keeps happening. Sometimes on initial power-up, sometimes during using the laptop, could be 10 minutes, could be a few hours.
Restarting laptop, the screen returns to normal. (this is the only thing that makes it return to normal).
The overbrightness is more than can set by manually adjusting the display brightness.
Ambient light sensor seems to be adjusting display when there is no change in ambient light.
Disabling auto brightness in display settings has no effect.
4:
UFEI Bios.
Update from Command Update application. Firmware update displays successful installation progress on bios. However subsequent Command update shows not installed. On third Command Update attempt the Bios update is installed, but took 15 minutes waiting at the Dell bios logo before booting into Windows.
Also have some strangeness when changing the optimised/quiet setting. It takes 30 minutes or so to boot back up past the bios each time this is changed!!! This really suggests to me something is fundamentally not right...
UEFI hardware diagnostic reports no issues or errors.
Windows 11 Pro is up to date.
Dell Command Update all is up to date (drives / bios).
Would welcome anyones advice!
