  1. Thanks again Khenglish and jaredhello, this was very helpful. I find it interesting that the high voltage rail is tied to external supply voltage. I would have guessed that it matched desktop rail standards, basically that the motherboard dropped it down to 12/5V before sending the line to the card. The bigger pipe is less power limiting, so that must be the thinking. Limits using higher voltage supplies with future laptops, but I suppose there isn't much reason to go above the voltage specs of the 330W Clevo bricks. I'm going to spend some more time of Digi-key now. I believe I already found the matching 2V 560uF caps. Originally Panasonic caps all around based on the pictures, but maybe I can top them from someone else. Thanks for an estimate on the small cap size, finding that one has been killing me. I'll look for 24V+ in that size and find the best capacitance/esr balance. Kheglish, you mentioned two Vcore caps, are the two down and right not the same as the array of six above?
  2. Khenglish, thanks again! I will be attempting the fix and adding additional capacitors as well. Do you know the voltage of those two sets of caps? The E7 ER are on a 12V line, and the set of 6 ( plus the two down and right?) are at core voltage so ~1V ? Would I be okay with 16V+ on the small caps and 2V on the set of 6 (+2 extras) ? You mentioned 25V before, which seems really high unless it's to protect against spikes (or the line is actually that high.) Wouldn't 16V with higher capacitance/lower ESR be superior? I could find some with greater handling of spike current also.
  3. Big thanks for this information, Khenglish! I'm going to get in touch with rjtech and request prioritization of keeping the card. I'd like to avoid the silicon lottery after winning it the first time. I will look for threads related to adding more of the 470uF capacitors, also. I'm pretty curious how this would work, since I don't know where they could be physically placed off the top of my head. I'm 99% certain it was only a small E7 ER that blew and not the larger ones. In the photo it looks like everything is in bad shape because of the debris, but it was all from the one source point. I have one question about all of this, should I be worried that this happened in the first place? Is the power distribution of the pack/motherboard/mxm just going to spike like this again and kill more capacitors in the future? If I replace the broken one and add two more new ones like you mentioned, will they randomly die again or was this a low quality part chosen by nvidia to limit the potential of the cards? I may not have mentioned it before, but I had the graphics card at completely stock settings when this happened. I had been restarting many times in rapid succession as I tried different system memory overclocks (which might have been bad for how these capacitors are used), but everything was stock on the graphics card. Maybe too many boot spikes in power overwhelmed the capacitor when it hadn't been fully discharged from the previous times it was on?
  4. Very exciting! I probably have the wrong connector on my P770ZM to drop it in, but I'm glad they're recognizing the demand!
  5. Take a look at the P770ZM, it should cover all of your bases! There should be plenty of info in the Clevo area to get you started.
  6. This is pretty much a shot in the dark. I haven't had much luck looking up what I think is a fuse. On the top side of the board, opposite the MXM connector end, One of the two E7 ER [+] labeled chips blew out the side. The machine was unphased when it blew during powerup and continued to boot into windows while I was holding the power to force shut down. This is what makes me think it was a fuse that successfully ate the power spike or something along those lines. It will be headed off for RMA soon. I'm curious if anyone knows what the chip is? If it's fixable, I'd love to keep this 980M since it can handle +370/+425 @ +125mV. Thank you in advance for any information you can provide. (I have pictures, but it looks like I don't have enough posts here yet to put them up from my pc?)
  7. Honestly, I'd like some more monitor options at 17" before I worry about form factor. The P770ZM is pretty perfectly aligned with my taste otherwise. I know this isn't really on Clevo overall, but if they could put pressure on their panel sources to get something >1920x1080 in the works, that would be awesome.
