Dell Precision M6700 Owners Thread

That should be fine, but that will be converting an analog signal to a digital one. You might notice artifacts (ghosting/blurring) at high resolution.

 

Is this limitation just a VBIOS setting and could somehow be unlocked?

Edit: I see mentioned on another thread that the video lines are physically cut. That's a shame.

 

Hi all. I've got an M6700 with a K4000M GPU. Windows is telling me that it can't see the GPU (can only see the Intel graphics). This happens intermittently.

Is there anything obvious I can try that might fix it, before assuming it's a faulty card?

Thanks

 

have you tried disabling optimus in the bios?

 

Are you booting UEFI? What vBIOS version is your K4000M? (Check with GPU-Z.)
There is a vBIOS update for the K4000M that has some UEFI fixes. Early cards might not have it. The updated version is 80.04.5A.00.02.

 

I was playing doom eternal on high settings and suddenly my whole laptop just cut off. When I plugged in the power supply cord the blue light went off and the computer wouldn't start, when I took out the battery and just used the adapter the sound buttons and the power button lights were blinking along with caps lock light all together.

I took it apart, took out the 980m put it back together and it started right up using it now. I didn't think those settings on that game would do this, I even turned down a few of the settings that the game selected from ultra to high. It certainly didn't look like a game that was that taxing to me by graphics.

The laptop has plenty of airflow on a hard table and is always plugged in. I've attached a pic that to me proves it burned out around the R22, R56 and some smaller components had some crispy looking stuff at the solder points. I'm probably going to try to put it back in and see if it's definitely the problem but since this booted right up without the 980m I don't know what else it could be. Any thoughts? Is there anything I can do with the 980m? I'm not sure there would be someone who could resolder etc in this small town.

 

That's probably a burned core mosfet because of poor contact with the heatsink/thermal pad, you probably need to replace on of these three 87850D (or something similar, I don't remember the exact reference), with an ohmeter you can check between R22 (check them all) and ground and between R56 and ground.

 

Thanks. Don't think I can - is Optimus part of the Graphics settings section? If so, I can't access it as the BIOS doesn't see the GPU at the moment.


I will check it once I am able to though.

 

Thanks. Yes, using UEFI. Can't check the card BIOS as the PC doesn't know the card is there, so it isn't seen by GPU-Z.

When it next detects it (as I said, the problem is intermittent) I will check. I can find no way to force it to detect it though - it just sometimes does and sometimes doesn't randomly.

Thanks

 

Yeah I don't have those capabilities at this time. I was just going to grab a 970m which is the only decent priced one near a 980m on eb atm.

---I have bigger problems now, upon reassembly later on, without the gpu, and upon powerup I smelled a faint burning! When I unplugged and moved it to disassemble, I noticed that there was what sounded like a loose missing screw in the case, i don't know if this had anything to do with it or not. Smelled strongest near where the GPU used to be but that could be the fan pulling it that direction. Upon teardown I couldn' t find any obvious burns on the motherboard, cpu was normal looking.

I put it back together, turned it on and nothing, only the CAPS LOCK little light goes on but nothing otherwise. Any ideas? Does the capsL light on solid but nothing else indicate anything? Dell diagnostics articles are so useless and tedious to find. Should I just clean the MB with alcohol and try again? Anyone with any advice or experience?

Since I have a complete laptop with all the components I would probably get another m6700 barebones if this MB is gone, but what a bummer now that all the latest games are coming out and I'm stuck with using my backup m4600 dual core with an M4000!! blurry slideshows or old games ugh.
