No I haven't sent it out anywhere just yet. I'm going to poke around in the engineering labs at school and maybe ask around to see if I can find a hot air rework station (or see if anybody experienced there would do me a favor). I'm a little embarrassed to admit, but I'd planned on using just the iGPU so I just pulled a dead Quadro FX2800M from a scrap box and plugged it in without thinking about possible consequences. That said, I'm still planning on not using a dGPU and I guess I still haven't learned my lesson about tinkering with things I don't quite understand, so I'm thinking about making a placeholder pcb card with just a temperature sensor on board. After taking a look at the service manual and a mxm 3.0 spec sheet I found online (MXM_spec_v301_°Ù¶ÈÎÄ¿â), I whipped up a schematic that I was hoping someone more knowledgeable would be willing to critique. Also, the spec sheet says some pretty specific things about the thermal sensor in section 3.4.10 at the bottom of the page, but I was wondering if I really do need to use the LM99 & 3904 combo or if I could just use a simpler local temperature sensor provided I give it the proper SMBus address. In any case, thanks for the help!

Took a glance at the graphics card, found what I believe to be a busted capacitor. Potential culprit? Anybody care to venture a guess at the the likelihood I've also zapped my CPU & other components? [ATTACH=CONFIG]12681[/ATTACH]

Midway through a Windows install, I bumped the laptop, disconnecting the AC adapter, so I just plugged it back in. Lo and behold, the laptop shuts down and I smell a heart-dropping smoky smell coming out of the laptop right around the HD bay. Poking around a bit, this is what I saw. (bubbled P2808 B0 chip right by the ribbon) I'm a bio guy by trade, so I'm a total newbie at this sort of EE stuff. The service manual schematics are quite a bit over my head and general internet browsing hasn't treated me much better. I was hoping to get some feedback from you more experienced folk as to the prognosis for this board and the courses of action that I can take from here. I'm talking to the reseller I got the laptop from, but I'm using Prema's bios and a graphics card from an HP so I'm pretty sure I'm not going to get in-warranty service. Thanks!

So this is where I'm at. I have a Clevo P150SM-A, put an i7-4710MQ in it, and don't plan on using a discrete gpu at the moment. I scrounged up a non-working Quadro FX 2800M and plugged it in just for the temperature readings so that I can boot. I flashed Prema's (thank you by the way Prema) P150SM-A mod v1 successfully, and managed to turn the dgpu off. The problem is that it won't stay off. Whenever I shut down/sleep the laptop, the dgpu comes back to life on reboot. That is, it's still non-functioning and undetected, but it starts drawing voltage and overheats (since I didn't think to get a heatsink for a gpu that I didn't plan on using). I've figured out that if I change the dgpu generation (say for example from gen1 to gen2), and then f4 save and reset while the laptop is connected to my ac adapter, the dgpu will then be turned off again. I was hoping there would be a more elegant solution to my little dilemma. Any help would be greatly appreciated. Thanks.
