M4800 Owner's Thread

Monitor Name (Manuf): LQ156D1 [DELL P/N: 71YHK]
Monitor Name: Sharp [Unknown Model: SHP1430]

 

As I am using the M4800, the downside of having much slower video card is pretty obvious. It is a sarcastic moment: having 4k, and almost 3 times slower card, compared to M6100. Needless to mention K5100M. Having one less HDD bay is a limitation, indeed. I have a mirror space, 2TB, would be nice to have a extra scratch disk of 2TB. 4940Xm throttles, but I intend to repaste it with a good paste.

 

What reason do you have for 'spamming' the power button, particularly before allowing it to go fully to sleep? That doesn't seem like a bug if it should happen to reboot. Seems like you shouldn't be doing what you are in any normal situation. Why not wait for it to go to sleep, as in a normal situation? Then press it once to wake it up again after a minute or so. That would be a normal situation.

I don't understand. ha. Just doesn't seem like a normal scenario that would happen unless you have little kids around.

 

I agree it's not a normal scenario but I don't think that's the point. If you pay good money for a workstation you'd expect it to have 0 issues as the manufacturer would have fully tested the machine under lots of different use conditions.

 

I still dont get why would any usage condition include spamming power button. Nhf but this looks just like splitting hairs issue to me rather than a real bug...

My thoughts exactly.
I tried to replicate what scrlk was asking for because I overlooked the 'spamming' thing and thought his machine was having problems waking up from 'sleep' mode, in normal conditions. Spamming the button while the computer is still 'falling asleep' does not seem like a normal procedure to me... and not a particularly healthy one either.

With all due respect, scrlk, I think your issue qualifies better as a curiosity rather than a 'nasty bug'. The situation is just a bit far-fetched.
I agree that a workstation-class laptop has to endure more abuse than a regular laptop, but it is nonetheless a computer and requires some sensibility while operating it (just like any machine, really).

 

Hi everyone,

We purchased three of these for work (see config in my sig below). They've been in service for about four weeks.

Two of them have experienced a "hard lock" — on one of them it's been happening about once per week, and the second machine just experienced this issue for the first time today. By "hard lock", I mean that the PC completely locks up, unresponsive to the mouse and keyboard, and must be forced to shut down by holding the power button before anything else can be done. I was wondering if anyone else has experienced this and figured out why (before I go calling Dell warranty support). One machine I'd chalk up to a fluke, but two out of three is downright disturbing.

The only hardware modification that we have done is add the mSATA SSD.

[Edit]
Not an uncommon problem, I see, reading through this thread...

Try disabling LPM?

 

I just received my M4800 with the UHD screen and the NVidia K2100. I also ordered a P2415Q 4k monitor for external display. I would like to get a second one, but I have not been able to confirm that I could drive two 4k monitors at 60 Hz. I had thought I could do this with an E-Port Plus off its two Displayports, but I have found no evidence that anyone has done this successfully. So far, my own test on the dock shows that one of the Displayports can run the 4k monitor, but that the other one cannot. I don't know if it is a faulty port, or a design limitation. Does anyone have any experience with this kind of configuration?

 

HEY! any one know: does fhd version and qhd version, has same connection to MB?

any successful swap stories?
