  1. The factory paste job on mine wasn't anywhere near this bad... I had the board replaced a couple months ago after suffering the "battery gauge reset" failure and they had actually done a pretty good job. Since they had somebody out here on-site to replace it, I just gave the guy my own tube of MX-4 to use when putting it back together with the new board. It didn't make much of a difference here, but then again mine didn't look like the disaster shown in your first image...
  2. Is he? This is a Y580 thread...
  3. Nah, it definitely still occurs on newer systems than those with 2.03. Mine shipped with Windows 8 and was therefore 8.01... same shit.
  4. Yep, just had my board replaced a few weeks ago for the same reason. The relay on the board that allows it to cut over to AC power while a battery is inserted is toast. Sometimes the AC brick will fry too; it looks like Lenovo accidentally shipped a 90w brick with my system instead of a 120w brick... my brick fried when this happened to me and the replacement they sent out is beefier/of a different design. It's a really unfortunate pain in the ass.

    Y580 fan control

    Has anyone figured out which EC (embedded controller) registers control the fan on this thing? I flashed the unlocked BIOS in svl7's thread in hopes of the thermal control options having some effect, but no go--they do nothing. So, I'm attempting to figure out which EC registers control the fan speed so I can control it directly. It looks like register 06 holds the current fan speed, register AB seems to be part of the determination in whether the fan speed is automatically controlled or not, and register 01 changes from 85h to 01h to 03h when I start the fan dust extraction function in the Lenovo energy management software (and then reads 00h for a split second before reverting back to 85h when the dust extraction is complete). Register AB changes from 08h to 00h when the dust extraction is running and manually programming the value as 00h seems to stop the fan speed from changing MOSTLY, but it still trickles downward slowly (no automatic speed increases at all with a value of 00h in AB). However, I have not yet found which register to write in order to actually set a fan speed myself after disabling the automatic speed adjustment. Can anyone help? Once this is figured out we will be able to control the fan speed using the generic NoteBook Fan Control utility found at http://sdrv.ms/P6RKKe. I've looked around for any information I could find on the subject and have come up empty handed. I've also checked out the source code for the ideapad-laptop module in Linux to see if any of the EC offsets used there were relevant to the Y580, but that was a no go as well.

However, I have not yet found which register to write in order to actually set a fan speed myself. Does anyone know what EC this laptop has so I can possibly look for a whitepaper specifying which registers do what? Sorry if this is the wrong thread to be asking this... this is my first post here. Edit: OK, I guess I've made 2 posts previously that I have no recollection of.
  7. You know, now that I think about it they would HAVE to be different. Y580s that shipped with Windows 7 would have to have a SLIC table for licensing and those that shipped with Windows 8 would have to have OA3.0 and all of the secure boot stuff it needs. svl7, can we get a modded version of the current version Y580's BIOS?
  8. I have the same problem. I tried it a couple of times and got the same result each time... almost thought the thing was bricked the first time it happened, since the keyboard didn't work anymore and I had to pull the battery and power to get it to restart. Maybe the system board has been updated between the original Y580s that came with i7-3610qm and the newer ones that come with i7-3630qm? It could explain the apparent differences in BIOS version number as well (2.06 vs 8.01 in this case). They both say the platform ID is QIWY3, though...
