Clevo P870DM-G power issue update

Hey everyone so I still have a problem with my Clevo P870DM-G Laptop it uses the Dsanke Bios for my i5-8600k for GPU I have a GTX 1060 MXM.
One day my laptop just turned off spontaneously trying to turn it on just resulted in a backlight bootloop.
The backlights would turn on but the laptop would just turn on and off in a boot loop so I left it alone for a while now the laptop turns on backlight and everything but nothing comes on screen.

The power button backlight comes on, the backlight behind the screen comes on, but not the keyboard backlights.

The GPU of my laptop looks good it hasn't shown any signs of physical damage I tried removing the CMOS battery I tried FN+D + Power nothing has worked so far.

Tried removing the battery and powering it on with just the cable

 

Retry reflashing the BIOS with a spi programmer

Have you got access to another MXM GPU ?

I just think it would be safe to try another GPU 1st

 

Does removing the gpu and trying to power the system change the behaviour?

 

Nope behavior stays the same.

 

Did you retry flashing the BIOS with a spi programmer?

Have you tested with an external monitor?

 

I'm trying to do that but I have a bit of a dilemma the cable for the test clip the red cable and the grey cable next to it somehow got snapped off, so I'm trying some wire repair.

Though I personally doubt it's a bios error unless the boot loop initially where the backlight would turn on and loop would be a symptom of that.
Though honestly if I can avoid a bios reflash that would be preferred since getting the bios chip exposed alone is a pain in the ass, doing the whole test clip spi programmer is another pain in the ass as well.

Not yet I'll do it after I resemble the laptop

 

Its more likely hardware rather than firmware related with those symptoms.

 

It was working fine until June 13 2019.


I took out the CMOS battery and put it back in after a bit, the backlight issue got resolved but nothing comes on screen.
Currently the fans works, the keyboard works I can press FN + 1 and get max fan speed.
It powers on with the battery and power cable so it still charges
But there is still no display.

Specs are GTX 1060 MXM, i5-8600k(bios modded), 8GB DDR4 Memory, 500GB SSD, and 1TB HDD.

I also tried what you suggested hooking it up via HDMI it didn't work

 

Maybe the GPU bios might be bricked? @Prema

 

I'm thinking the GPU. Do you have another laptop to test it?

I take it you don't have a spare 970m/980m laying around? Even an old kepler will boot (I've booted numerous 870DMs with a 765m/860m), but you won't be able to get the drivers going, but you will be able to rule out
your GPU and get to BIOS and your desktop.

 

what is the lowest end cheapest GPU that would work with a Clevo P870DM-G if I can get it to boot.
Also looking at the GPU it has no physical damage to it so if it is the GPU that is causing the problem what is the issue with the GPU and how would I go about solving it.

 

Sometimes the damage isn't readily noticeable. Some members with trained eyes can pick up on damage quickly. Post a pic of the card front and back.

As for what will boot, I have tested and know the 765m, 770m, 860m and 870m will boot and post in a 870DM. They were all Clevo branded cards, though. I can't vouch for Dell or MSI.

I wish I had known last week, as I just sold the last Clevo 765m I had. I tend to keep some around as test cards for various dead laptops that float through my way.

 

The 860m from that list if you can find it will be the cheapest.

 

Any old quadro will work. I’m talking quadro m2000m. Even FirePro m6100 works in it. Literally all old edp supported mxm cards work in the p870dmg. I had tested almost 30 cards in that laptop. Cards with even a HP BIOS booted right up which astonished me. What I noticed is that it doesn’t like newer cards at all but older ones work, just make sure you buy a card that supports edp output. So the FirePro is your best option as it’s cheap af. Like $50.

 

True, a m1000m booted up no problem in mine, but they are maxwell based, so that would make sense. I never got a chance to try any FirePro's yet. Did you actually manage to get any AMD cards to fully work with proper driver installation in the 870DM?

 

Yeah, the m6100 installed the driver automatically via windows. The card worked flawlessly, fan control worked also...

 

These are the graphics card pics and yes this is my hand

 

I wonder if the issue is the CMOS battery
Is it possible for a Clevo P870DM to function without the CMOS battery
When I take the CMOS battery out
it just turns on and off
when I just press the power button
but when I turn it on with FN+D it turns on but still black screen

 

Who else’s hand would it be?

CMOS just retains your hardware settings. But a 870DM will work fine without it, but if you lose complete power (wall, battery) you will have to redo your settings. You will get a warning about cmos settings being reset.

As to whether the battery is the culprit, only insofar as it is allowing your system to retain a faulty setting but a reset would have cleared that.

Did you try the replacement card(s)? If so, what happened?

 

Haven't tried a replacement card yet but I got @woodzstack 's opinion and he said the card looked fine. So maybe it's the motherboard. Though I did hear that some mobos won't post without CMOS.

I'm thinking it could either be RAM, CMOS, CPU, or Motherboard.

Though I ask if it's true that a CMOS battery wouldn't do much then I wonder why the laptop would instantly turn on, then shut off when a cmos battery isn't present in trying a regular boot.
But a FN+D boot it boots but black screen.

 

I’m pretty sure I’ve booted mine with the battery unplugged. I can’t see the cmos battery being the problem.

The odds of both memory modules failing at the same time are pretty low.

You really need to try another GPU to rule out your card or try your card in another laptop, but it does look clean. Where are you located?

 

Live in Calgary my man.

 

It looks like you have paste of the memory on the card. Did you have pads touching the vrms?

 

Yeah I believe I have the thermal pads touching the VRMs of the GPU.

 

Were they making good contact?

 

Bummer, there's always a chance somebody is within a 100-200 mile radius for a meet up so we could try some cards and take a look.

 

I talked to Danishblunt he said the internals of the GPU are ****ed.
Pretty much the CPU fan would spin but the GPU fans wouldn't.

So I'm just like **** it I'm either selling the Clevo P870DM-G and going full mini ITX
or If possible PCIE 3.0 to MXM I have a desktop GPU but I need a way of connecting it to the laptop.

 

If the card isn’t detected properly in bios, dsanke sometimes requires manual fan controls for GPU. My old 980 required manual fan controls with dsanke. I just used obsidian fan controls to fire up both fans. Were you running it all this time with the fan(s) not spinning up properly when under load?

You could always drop a cheap 970m in there and go external GPU too. I used to run a 980 but it was major overkill for my needs. A 970m gets it done on the road for me.

 

alright
um
I did a retest last night and today
What happened was strange
Ok so when I don't have my laptop plugged in just the CPU fan spins, then the laptop just turns off
When I pulled it in today it was just the CPU fan just spinning right then what happened after I just shut it down and restarted?
Not only did the GPU fan start up automatically'
The graphics card heat up
along with the heatsink]
In the MXM Master slot
This also happened last night as well
When plugged in the GPU would heat up, and the fan would spin automatically
I held it in a way where pressing FN+1 was impossible

 

Ok so now my laptop does this

 

I'm not a expert but that GPU looks unhealthy. Very easy fix put a new GPU inside

 

Corruption in the bios screen is usually a pretty terminal sign for the GPU. You can try seeing if there is something up with the display cable say if the corruption changes when moving the display but otherwise it's the GPU.

 

GPU is dead

 

Is this GPU not fixable? I'll get some pics but it doesn't seem like there is any frontal damage but there may be something blown on the back.

 

The card can boot into Windows and display text but it's artifacty everywhere else.

The main GPU looks fine but there seems to be something that's morphed I wonder if it's replaceable.
The card displays things and functions but it's defective.

 

What exactly looks morphed? Can you take a picture of the GPU itself?

The GPU is most likely irreparable. For the heck of it you could try heating it up in the oven and see if helps in any way (although I would recommend against it!).

 

My tech guy hasn't sent the picture to me yet so I'm not so sure.
But it looks like something on the back is morphed.
The frontal part of the GPU looks fine, the die looks good.

Unless the thing causing the artifacts is something inside the GPU die.

 

Out of curiousity though with what you have seen so far what could be causing the GPU issue.

Would it be the die, memory, or something else on the card?
Is that something else replacable?

 

Most likely a VRAM chip. What caused it to get damaged? That's a tough one. Depending on your usage and care, and how long you've had it, it might've been damaged by long exposure to high heat.

 

I've had the card since April 2018 it was running fine then I had a i3-6100, then I upgraded to a i5-8600k
The GPU started having heating troubles when playing certain games around Jan 2019 I wouldn't be playing those certain games until April-May 2019 Where I solved the problem by putting paste around the whole die.
What would happen is in certain games the card would reach to heat of 80-90 percent then it would just shut down, I applied thermal paste to the whole silver part of the die, and used the paperclip mod the heating issues resolved themselves.
What I would also do is I'd run the fans up to 100%, and downclock the card, and memory to the lowest in MSIAfterburner before playing any game.

Due to the heating issue though I mainly used the computer for web browsing, and some blender work which didn't cause any troubles.

 

I can also login to Windows
The Icon, my name, and where to enter the password are clear, in the background I can also see parts of the background image but it's covered with artifacts

 

Alright so right now I'm trying Video Memory Stress Test
The Driver is Microsoft Basic Display Driver so far I haven't been able to install the NVIDIA driver or reflash the bios.

I'm thinking what it is, it's a on die silver part GPU issue.
Might need to try the oven trick or something not so sure heh.

But yeah so far memory is looking to be ok.

 

Unlikely to be fixable unless you have a very good local specialised shop.

 

Yeah at that point the oven trick might be a last resort. If the card is no longer under warranty, it might not hurt to try. You could always try selling it AS-IS on eBay to recoup at least some money.

 

Easier to judge with a couple pictures of that.

 

Looks like a cap and does not look too healthy.

 

Yeah that's not gonna get fixed by the oven trick. Oven trick is for repairing components' solder, sorta to "refresh" the circuit glue if that makes sense.

Your card needs a more serious work and you might end up spending more than the cost of buying a new one.
