M4700 Owners Thread

So I got my m4700, got my ssd, installed windows, and now I am having a hell of a time getting drivers set up. I found a .cab but have no idea how to install it. Anyone have instructions or a link to a guide? I did a search but everything was from 2004 and im not sure if it works the same.

 

Which drivers?

 

Does anybody else experience the following situation?

Notebook:
Dell M4700 w/FHD Display
UEFI A08
Intel 3740QM
8GB 1866 RAM
500GB Hybrid HDD
Nvidia K2000M
Intel 6300 WLAN
5630 WWAN
Windows 7 x64 Ultimate (Dell preinstalled)

Situation:
Cold boot (system was powered off before)
CPU load in idle state is at ~20% (2 CPU threads at maximum)

Now, performing a warm boot (reset) resolves the problem - CPU load at idle state is ~1-2% then.


Investigation:
High CPU load is caused by "NT Kernel & System" thread. ProcessExplorer reveals high interrupts load as the root cause. ACPI.sys is the system thread in question here.


Workaround:
The HW device leading to this behavior is the Intel wired network device (82579LM). Either disabling it in the Windows device manager ("resolves" the issue temporarily), or resetting the system (warm boot) makes the high CPU load on idle state go away. Re-enabling the Intel 82579LM lets the issue reappear.

I used current network drivers provided from Dell as well as from Intel, but no change in system behavior.
As this only happens after cold boot, i assume a UEFI issue here.

Or has anybody found a real solution to this?

I have similar specs, other than the Wifi card and all SSD drives, cold boot no issues with CPU load 61 processes running and less than 2% load

 

So I figured out that disabling the Wake on LAN feature in UEFI resolves my issue. Im on UEFI rev. A08. Re-enabling Wake on LAN makes the issue also reapper.

I will contact Dell about that.

Same cpu load problem. It is rare and I found sleeping/waking from standby is a quicker workaround.

 

Updated from BIOS A05 to A08 and CPU load at boot falla from 20-30% to 2-7% always with wake on lan off.

Windows benchmark rises from 6.9 to 7.0

 

Failed to install USB 3.0 A04 extensible host controller driver wrong operating system error ( with W7 x64).

Installed A03 version instead and worked ok

 

I asked in the M6700 thread and now, I'm asking here, if anyone can run specviewperf and luxmark benchmarks on their M4700, I'd appreciate it. I can always get the specviewperf results from notebookcheck if I need to, but I'd prefer results with current drivers. Of the two, I'm more interested in Luxmark since there isn't much info on the performance of mobile GPUs in OpenCL available.

You can find the links to download the benchmarks in this post: http://forum.notebookreview.com/del...sion-m6700-owners-thread-182.html#post9188917

 

Anyone using Ubuntu with their M4700s?

I'm with Ubuntu 13.04 - works quite good so far.
Ok, haven't tested WWAN yet, but it is recognized by Network Manager out of the box, so I don't expect problems here. GPS is of more interest to me, but I didn't find the time test that as well, yet.

My 'major' issue up to now is the fan control.
Fans are off for the first couple of minutes after Ubuntu has booted up. Then, the CPU fan kicks in and runs on normal level as it would also do in Windiws. But it won't stop again, regardless of system usage/idleness. I got CPU temperatues of 40°C, and the CPU fan still keeps running. I'm using the Intel GPU HD4000, not the Nvidia card.

Anyone else experiencing this? Solution?

EDIT: OK, seems that there is another source of heat, since CPU fan exhaust gets a little bit warm (barely hand warm). But appearently still warm enough to let the CPU fan run continuously.
