*** Official Clevo P775DM2/3(-G)/P75xDM2(-G) (Sager NP9152/NP9172) WINGMAN 2.0/BATMAN 3.0 Lounge ***

Still thermal limits.

 

Looks like my P775DM3-G's display is about to bite the dust. Had a slowly but steadily increasing number of dead pixels in the lower right corner for a while, but since the beginning of the month, I've been also experiencing occasional flicker, so I'm planning to replace it.

Any recommendations?

 

What have you got at the moment?

 

It came with a 75Hz, 1920x1080px matte IPS panel with G-Sync (probably made by LG, though my memory is a bit blurry).

Replaced it with some vanilla 60Hz non-G-Sync display (definitely made by LG) I got for free when stuck pixels in the very center of the screen rendered the original one unusable.

When at home, I usually hook the NB up to my TV nowadays when gaming, so bleeding edge specs aren't a must, but I occasionally use it for digital image processing, so decent colour fidelity would be a big plus.

 

What's the exact model of panel you have now?

 

According to HWiNFO64:

Code:

Monitor Name: LG Philips [Unknown Model: LGD0459]
Monitor Name (Manuf): 173WF4  [DELL P/N: CV69H]
Monitor Hardware ID: Monitor\LGD0459

There are the full specs so you can match up.

 

Reposted from the other (wrong) thread:

Hello everyone, I'm trying to troubleshoot a issue on my P775DM3 laptop, that can't boot and shows no image on the display.

On friday I was using it, playing while watching a stream on the second monitor, while suddenly I had no video anymore, while still able to hear both the game and the video's audio for some seconds before I tried to reboot it forcefully.

To be clear I has something unusual happening earlier the same day, as I turned the pc on before making lunch, but found it off when I sit at the desk later. Barely minutes after I turned it on again I had a low battery alert, although the AC adapter was powered and connected to the pc. I turned everything off and let it recharge, and didn't think too much about it other than maybe I had too many electronics plugged in the same socket. A similar things happened last year.

Anyway, now when I try to start the computer, I can't see or hear anything except from the fans spinning normally and the hdd/keyboard leds working.
After around 30-40 seconds the fans start spinning at full speed, while the ac adapter led blinks orange instead of the usual full green light. This goes on for one minute or less before the computer turns off.

Because I could not get any video signal I suspected at first the GPU, or the RAM. I opened the laptop, disassembled the heatsink and checked the GPU pcb but didn't found any evidence of damage on the components. I also replaced the RAM sticks and reassembled it, but nothing changed and the same behavior happens.

Another thing to mention is that when disaster struck I was running the pc on a OC profile of 3.9ghz, instead of the normal 3.5ghz speed of my CPU. While I don't monitor my temps as closely as I did when I first bought the pc in 2016~17, I don't think it's an issue of overheating. With a similar workload (same game running, and a twitch stream in the background) I had around 75-80°C on CPU and GPU a couple months ago. I also have a 4.2ghz profile that works flawlessly, although I really used it a couple times at most.

In short, can anyone help point me toward the most likely causes of the pc not working anymore? I wasn't able to find any error codes explanation in the Service Manual, and before looking around for a compatible processor in the eventuality that that's the problem, I would love a second opinion. Could this be a power issue? Thanks in advance to anyone still reading thus far

 

Does the behaviour change on just battery?

 

Nope. Same exact behavior. It changes slightly without RAM sticks, in that the fans never spin at full speed and the power led never blinks orange but stays full green, and the laptop eventually turns off.

 

Could well mean the GPU is dead even without physical damage on it.

 

I see, it could very well be a costly troubleshooting in that case. For now, I've bought a used 6600k, I hope that'll solve the issue.

If not, is there a list of specific video cards that work on a clevo? Both hardware and firmware wise. My pc has a custom bios made by the seller (European Obsidian-PC, not in business anymore), but I don't think cards more recent than the 10xx series would work without flashing another firmware.

If the GPU does not work and I buy another one, in case I need to can I flash the firmware blindly (ie. with the screen not working) ? Talking about either GPU firmware and motherboard firmware here.

 

Obviously any 1060/1070/1080 will be plug in replacements. Due to the shape of the card there are not many more options than the newer ones.

 

EDIT: nvm

 

As an update, I've obtained a used 6600k cpu to see whether or not my cpu was the source of the problem, and because it's cheaper than even a 1060 mxm gpu. I did these tests:

• Original cpu, no gpu connected: reading the rtx/9 series cpu bios mod thread, I understood these laptops could boot successfully without a gpu connected. For me, no changes. At this point, I was thinking that maybeee the cpu was the problem.
  
• New (used) cpu, no gpu. Again, nothing changed. Theory rejected.
• After reinserting the gpu in the slot and reassembled everything back again, still no changes.
• I've tried removing both ram sticks, booting while resetting the bios with fn+D, the pc turns on, then turns off shortly after and reboots.
• Put a single ram stick in the mobo, tried to again clear the bios with the keyboard shortcut, and had the original problematic behaviour back

Now at this point I don't know if the gpu is actually the source of the problem. Could even be a motherboard issue? I don't believe I completely ruled out the gpu just by trying without it connected, but I kinda thought (hoped) the laptop would have booted without issues.

 

The problem is there is no GPU at all without the dedicated GPU, you would have to remote to it I guess even if they did strip out the shutdown on no GPU sense safety.

 

Hi there.

I bought a LTE card and i wanted to plug it in. There are two cables, a grey and a black.

Does someone know which is the main cable and which is the aux/GPS cable?

I didn't find informations in the Clevo/Eurocom documentation.

Thanks.

 

I don't think it really matters too much.

 

Can I ask how did you implement 3070 in your 870TM1? this is my dream machine

 

I already had a Prema BIOS that supported the card, got a new heatsink from a contact on here ( @ViktorV ), tested the card worked and then immediately shunt modded it after getting the water cooling setup.

 

How does a laptop behave with a video card removed?

 

The black one is lengther than the grey. The grey is about 10/15cm long, the black cable goes around the screen.
Maybe it's not for the same frequencies. But maybe it's not a matter as you said, maybe the card analyse which cable is plugged.

A thing i can do it's to benchmark with grey as main then benchmark with black as main.

 

Wow! great job. How did you shunt modded? REplaced the capacitors or just pure LM?

 

Liquid metal but a minimum application variant. You put a blob over the contact patch you want, let it sit for a couple of seconds then quickly pull the blob in with the syringe. This leaves a very thin skin of material in place that wont move.
