One of the threaded inserts for the heatsink is missing from the motherboard. How critical is it that I find it or get a replacement before I reassemble?
Go ask an LLM. We aren't your tech support service.
>>108783579could be pretty critical in the long run, since it could cause uneven pressure on the CPU (and GPU?) die, it has degree of thermal expansion during operation which could exacerbate the problem. on direct die cooling like these it is more riskyor you could just yolo-it and it will work no problem for years, take your chance
>>108783579Very.
>>108783579zip ties.
>>108783579Very.Get some zipties.If the knob part of the ziptie won't fit through the hole, thread one through from the back and put a second ziptie on the tongue to lock it down.If it does, then put one through the knob first, so it's stuck on the back and then do the same.
>>108783617>>108783706>>108783744On the service manual page it only specifies 3 heatsink screws. Despite the heatsink having four screws on it (picrel), could this laptop have been made to be mounted with only three? From the first time I remounted the heatsink I took note of how that #4 screw didn’t seem to bite. There’s also no residue from any kind of adhesive. Maybe it was designed for three screws?

>>108783786are you reassembling for a customer or personal use? either way, keep an eye on the sensors and see if it is out of spec. do you have another identical unit to compare it to?
the heatsink seems evenly applied gonna check the temps when I turn it back on and if everything’s normal I’ll call it an anomaly and get on with it
>>108783786if the heatsink has a flat spot you can put 3 hairs on the rim, apply some paste and tighten it just enough so the hairs won't move
>>108783870personal useI had a look at the motherboards for sale online and they do have four inserts…
>>108783883could be a different board revision or something. idk, i would just send it. it'll likely be fine. did you check underneath the heatsink and or the mainboard for the thread insert?
>>108783579screw in 2 diagonally opposing screwsthis is a disaster and you are not going to find a replacement bracket even if it is mostly removablehow the fuck do you manage this you retard?
>>108783875remove this one, should be a plastic or metal clip on the bottom that can be removed but keep it around2 diagonally opposing screws should be more even than this shit

>>108783579>How critical is it that I find it or get a replacement before I reassemble?it doesn't matter, there's barely any heatsink pressure on a soldered laptop cpu, it's not an epyc
>>108783786>>108783791My guess is that they probably left out that 4th screw as a workaround for some design flaw, hard to tell just looking at a photo.
>>108783579if you thermal throttle often this will make it slightly worse since the pressure of the heatsink being uneven hurts heat transfer performance.if you're never near thermal throttle territory it mostly wont matter
>>108784074if the top of that heatpipe doesnt make contact with the laptop case you could put thermal pads or those foam things you see inside electronics pcbs on top of the heatpipe so the laptop case puts pressure on the heatsink
>>108783579Did you actually check the other side?
>>108783983>did you check underneath the heatsink and or the mainboard for the thread insert?nah, I gently rocked it side-to-side but nothing was moving. I considered removing the whole board but that would provide many more opportunities for me to cause damage.>>108784066I screwed in all three. I think it was never there to begin with. >>108784797Maybe not a bad idea.>>108784780I do some audio, image and video processing and it's always made my laptop fan spin up when it came time to export. I don't think what I've done today will hurt much. >>108785613Nah, too scared to lift off the entire motherboard. I could have, probably. It's working fine at the moment, <58C for browsing with multiple tabs and other programs open. It jumped to 92C for the Cloudflare verification though LUL and also hit 100C when I exported some images in my image processor. Went right back down though, fan didn't even spin up. Unfortunately I have no benchmark from prior to today to actually know for sure whether all this is normal but it does seem to be operating as it usually has. I also used the BIOS diagnostic and it didn't find any CPU faults so whatever.
a momentary 92C blip for demosaicing a RAW file. idk seems to be fine. doubt being able to thread that one loose screw could provide much cooler temps.
