Precision M4600 Owners Lounge

I can't get the display brightness to work on my M4600 running windows 10. Adjusting the sliding bar doesn't nothing. Stays fixed at full brightness.

 

I changed the motherboard on mine and Intel Turbo works fine, but a weird thing is that i can't recover from sleep or if i close the lid, i remember having an HP that had that issue and a Dell Vostro with switchable graphics and it needed a modded driver. But i don't know if its the same card or what

 

I have an issue that I want to ask here because it may be specific to the m4600. I have an m5100 firepro that I was overclocking pretty aggressively (using valuxins vbios), at 950/1375 and it was stable on most games. Temperature never got above 80, usually stayed in the low 70s.

I was playing the witcher 3 for a few hours, with the oc, then put the clocks back to normal and put the computer in hibernate. The temp hadn't gone over 80. It was the first time I had played and used the overclock in several months at least, but there have been periods when I was using it every day for several hours.

The next morning, i started it up and the screen was blank, windows 7 booted up, I heard all the sounds, but no picture. I could tell that the screen was on but it was black. Something like this had happened before, so i turned it off and tried again. Same thing, several more times. I cleared the cmos, and I was able to get into the bios. My Gpu is no longer listed under display adapters.... if I restart again its blank again until I clear the cmos.

My m4600 won't boot up without a graphics card, i understand this may be because I have an IPS panel? (im not sure). Would it boot up with a dead or damaged gpu and just not show video?

anyways, I would assume that the gpu is dead ,except that it didn't crash or freeze. It was idle and seemed fine when i put it in hibernate. Could the gpu die in its sleep? Im also wondering how the gpu could die like that at pretty healthy temperatures, so im guessing if it did fail it was the graphics memory?

I'm getting a cheaper card soon so I can test it, but in the meantime I was just curious if this sounds familiar to anyone, and if my gpu is dead for sure.

thanks and i apologize if this issue has been addressed somewhere else, or if this is just a common way that gpus die that im not aware of

 

IPS panel requires an NVIDIA GPU in this generation. If you have an AMD GPU then you do not have an IPS panel, so the laptop should boot without a GPU and run off of the integrated Intel GPU. (HDMI and DisplayPort ports don't work in this configuration, but the internal laptop screen should work.)

 

Dell is not supporting M4600 Spectre BIOS fix - (meltdown is covered by software) and I am looking for new bios or fix or to STRIKE against Dell so they release SPECTRE FIX for m4600


Anybody?

 

Err, a BIOS update for this is not required. It will come in via a Windows Update patch, just gotta be patient. Microsoft has currently released a fix for Skylake and up but they will be working their way down the CPU chain as the fixes are tested and released by Intel.

(Intel hasn't yet released a "fixed" version of the microcode update for anything below Haswell, anyway.)

 

Great,

so far InSpectre app shows M4600 win10 with avast free is protected against Meltdown but not Spectre.

So MSFT update with repair code starting with startup will be solution instead of bios changes...

 

Ok thanks, that's good to know. Yea it's starts the boot process and then says starting wondows then crashes with a blue screen if I try to start with no gpu. This could be because I have an engineering sample CPU, not sure yet. Does anyone know if you can install a mxm 3.0 type A card in a mxm 3.0 type B slot? I want to test the firepro m5100 in the precision m6700 I just got.

 

There should be no issues.

Might have an issue with the heatsink lining up but as far as just testing it shouldnt be an issue.

 

Yes you can, they are electronically the same, the only difference is the card length. (Of course, there's always the heatsink to worry about, it must make good contact with the GPU core and also not have any pieces that get in the way of chips on the card.)

 

Well, I got the laptop working again without the graphics card. I reinstalled windows and its working just fine off the integrated gpu. So it looks like the firepro m5100 was burned out. The core was never hot enough to have caused this (75 at most) so it must have been the vram, which I was overclocking to 1375 mghz. Has anyone else had a m5100 die on them after overclocking? This was using a valuxin vbios mod.

 

depends on your RAM chips.

They are not all made equal.
