M4800 Owner's Thread

So I was replacing the SSD my Dell came with for my 500GB... Clean install of Windows 10, updated it and when one update was done, the machine hard froze. I shut it down, turned it back on and it was in an automatic repair boot loop. Anyone else had this problem? And if so, how was it dealt with?

I've rolled it back though, so it doesn't freeze at all with no GPU drivers installed,must be software being the problem. But I had a message pop up at the time saying "System Settings Change" and "Your hardware settings have changed, Please reboot your computer for these changes to take effect !!" and it would just freeze there. I tried the latest driver, and that also hard froze after it restarted to resume and finish installation.

I don't think I'd have this issue if an Nvidia GPU's in there, but it could just be that the M5100 is old. Maybe the WX4150 will have no issue.

I had a look online and it's pointing to AMD. Only Windows install that works is the original one that was in the old SSD. I've since cloned it for the convenience and it's stable there.

 

Check Windows advanced power settings, specifically the value for PCIe "Link state power management". On your working Windows install, is it set to "Off/disabled"? (I've had to set it this way on M4800's before to avoid freezes.)

 

I'll check that soon. I don't know why it freezes just from installing the update which was actually the AMD graphics driver, I don't really know if it'll make a difference, only thing I can do is just try.

 

Try to disable Switchable graphics and see how GPU will behave. It's a good way to test if your new SSD is working properly.

WX 4150 is an awesome card (and you can confirm that by my signature, lol), I just don't think it's worth the price rn. I could ride the wagon for $69 when they were available for this price (and seller accepted 2 offers of $60), which is just an amazing price for performance (10% less than Quadro M2200), but I don't know if you can even find for less than $120 right now. $120 is not a bad price for this card, but if you are not planning to do anything that needs its memory (4GB) or simply its performance, replacing your defective Firepro for a new one seems to be a lot better idea, since you can find them for less than $40.

 

Well, I turned off SG and I have no internal display now. This is on the 120hz panel I installed, but prior that I did have the old 60hz installed and turning off SG worked there at the time.

 

Oh. It's probably not compatible with Intel HD which is... a new reason for not follow the WX 4150 path. WX 4150 is eDP only and you have to leave switchable graphics off with a LVDs screen.

Now I have no idea how to go back, lol. I was going to recommend to remove CMOS battery, but it'll probably just keep switchable graphics off. See if you are able to see bios setup with an external monitor.

 

Oh this is an eDP board. I replaced the board with an eDP version. I don't think it likes the LCD, and it's fussy. It might be to do with the fact it's 120hz, not 60, and it doesn't know what to really do. Device Manager can't see the panel. This is like HP Zbook 15 G2 behaviour but with the official card, but not original screen. Very odd. I know how to return it to normal with the CMOS.

I think it is the M5100, it doesn't like the 120hz if I am in WIndows. Going into the BIOS is just fine. I wonder what happens if I boot into Ubuntu on a Live USB... I'll test that, and if it yields an output on the internal then we know it's a Windows thing.

 

Not sure how accessible the BIOS is from an external monitor if switchable graphics is on. If it's not working... You should at least be able to access it from a VGA-connected monitor (shut the laptop lid quickly after turning the system on). The VGA port is the only port that connects directly to the Intel GPU.

 

Ah, you are good, then. Sorry, I was actually expecting Intel to don't have any issues with 120hz, but seems like I was mistaken.

I could find 2 options of WX 4150 in Aliexpress: $125 and $133 (4GB variant. Seems like they are selling a "2GB variant" which is a WX 4130 instead). For those prices is... acceptable. A lot less that you are going to pay for a Quadro M2200, but still... well, it's your choice now.

In his case, it was on before and he can't see anything with that deactivated.

 

I have a 4GB WX4150 for an HP that could just need a Dell VBIOS flashed to it. I bought that one for the Zbook but fan control didn't work properly.

There's no issue with Intel GPU on the Dell with the panel I installed.

Intel graphics picks up the 120hz, displaying just fine and smooth at 120hz and if I unplug the AC that goes down to 60. It has no issues with 120hz. But, turning SG off yielded that Windows didn't seem to like it much and didn't bring my internal display back with the M5100. I rebooted the machine into the UEFI setup and the internal panel returned like normal. I still need to test a Live USB of Ubuntu and if it brings the panel up there, then it's a Windows thing going on.
