M4800 Owner's Thread

Could they be sharing a communication bus (so that only one can be active at any moment)?

 

Maybe... But I just tried with an external USB keyboard (hold down "W" key on external keyboard and point stick still does not work). In that case there shouldn't be any hardware-level conflicts.

 

I think it's the touchpad/trackpoint driver having a really aggressive palmcheck feature.

Kill the Alps driver in task manager, it'll solve your problem.

 

Umm, it seems a deliberate feature.
(As such, it could—in theory—employ some switch in the registry or somewhere.)

 

An update on the W10 M4800 battery life.

Decided to tweak the 'balanced' power plan - forced graphics to have maximum power savings and capped the CPU to 50% state (= ~1.2GHz). With similar loading to my original test, got around the same battery life. W10 settings app saying that most of the power consumption on my M4800 is due to the screen, despite the brightness only being at 30%.

 

the pointstick+ keyboard issue is definitely a driver issue and was reported since the x600 generation(including latitudes machines) . Dell never bothered.
there are 2-3 process you can try kill to make them working at the same time.

 

I was thinking… the shorter battery life could be due to Nvidia drivers not properly optimized for Windows 10 yet, perhaps. It’s just a thought off the top of my head. Do you have, in the notification area, the Nvidia rectangle that turns grey when the GPU is fully inactive but stays colorful when the GPU is active? Is it, by any chance, staying colorful? That could explain a lot.
(There are conditions under which it will stay colorful despite the tool-tip claiming no activity.)

 

You can get this icon to show up with the "Desktop -> Display GPU Activity..." option in the top menu of the NVIDIA control panel.

On my M6700, looking at the Optimus test tool and also GPU-Z, I am seeing the NVIDIA GPU turn on and off a lot (when nothing is running that should prompt it to do so). Like, on for a few seconds, off for a few seconds, on again. When it is on, the Optimus test tool shows the state as "IDLE" (instead of "OFF").

I haven't spent any time digging around to see if there is a process causing this but the Optimus test tool doesn't list anything. But this sort of GPU behavior could certainly impact battery life.

 

Hi baii,

please could you explain how to find the detailed config ?

Do you know if the M4800-4623 (E-Value code: CA201PM4800MUMWS) comes with the EDP/IPS display ?

Thanks

 

you need the service tag, or express service code
