M4800 Owner's Thread

Keyboard input improvement - I wonder if this will fix the double keypress problem that I remember some people having earlier in the thread where one keystroke would register as two.

 

Just for the heck of it I sent a support request asking to see about the throttle issue in the next bios release, not that I thought they would admit anything "wrong" with it.

"I'm not sure why you would use any adapter that is under 180Watt. That is the adapter designed to be used by the M4800, and normally it will throttle the performance any time there is less than the optimal wattage detected. It may not even matter what BIOS version you are using. This is probably not something wrong, I am pretty sure that you are lucky that your system did not throttle if you use an adapter under 180Watts."

 

Some issues may be solved with new BIOS release "M4800A09" Driver Details | Dell US

 

Any what did you reply to this nonsense?

 

Someone asked for the keyboard issue. I can report - after three days of testing the new Bios version - that the double key issue has become worse. Now, on rare occasions a key hitting results in uncontrollable keyboard behaviour (for instance, thrity times in a row backspace, or any other key). However, this is occuring at rare intervals.

The kernel messages reporting for the Dell 5570 have changed, maybe the card works from now on properly. But I haven't had time to test it yet.

 

Greetings to all forum members
I have a dell precision m4800 with 8gb of ram, i7 4800 CPU and screen with resolution of 1920*1080.
I have notice a very strange situation in the last days. When I start the operating system, windows 7 64 bit, I have one core that always work at full speed but if I start task manager no process is running. To investigate the strange situation I start process explorer and I can see that the process ACPI.sys+0x1af7c running in a strange loop and uses the full CPU (fortunatly only one core). But if I restart the PC, restart from the start menu and not turn off and turn on the laptop, at the new restart this strange situation is disappeard. Then if I completely turn off the pc and restart it the problem restart. Why? Did some of you notice this strange behaviour? Thanks.

 

Nothing - doubt it would serve much purpose. What may help is if more people complained about the issue so they would know it wasn't just me being "lucky"

 

I did, right after A07 was released. However I also believe that only when we show them that we do not swallow excuses like stupid sheep they will start their thought process that it might be an idea to take take out this overly aggressive throttling again.

 

I am done....its over. Dell is taking this problematic machine back, I am going with a MBPr 15.
Here is a list of issues I had with my $4800 M4800.

• Paint wears of literally within a week
• Raid array never worked right
• 130 watt adapter will throttle it but 100 watt battery runs fine
• Sleep states are all messed up, will fail to wake up from sleep randomly
• Even with the extended battery, it wont get more than 3 hours of real life usage
• While in sleep mode battery will drain to 0 in less than 12 hours
• DP 1.2 only works out of 1 port replicator port and not the other, randomly fails to detect 4K screen. (mostly a Dock issue)

I am glad at least Dell is taking this thing back. I like Dell products and we use a lot of stuff from them, but this laptop specifically is haunted by the devil or something.

 

Does anyone know how direct connect works on the Dell m4800 (Windows 7 64bit)? Drivers have been installed w/o a problem. The unified wireless application finds the 'direct connect' device, but can't connect (not with quick connect, nor with key pairing connect).
In this case it's a smartphone with Android 4.3. When I try to connect from the phone, a notification pops up in the Windows system tray to accept or ignore, but the connection can't be established.

Devices are shown on either end, but connecting fails.
