    820-3208 Need Bios with SN added

    I put that on. It had an EFI passcode. I removed it no biggy. Its still running really slow. Starting to think its an issue with the SSD possibly? Although the mouse seems sluggish also so it seems like a Kernel Panic kinda of slowness.

    820-3662 possible fix? Simple script

    realmacmods didnt know you were on here. Yes seems to be working great. If you dont mind spilling a few beans what seems to be the root cause? Is there proof in older firmware that they dont drop voltage that low? Is this literally a flaw in Intel Power States where the CPU is put at such a low...

    820-3662 possible fix? Simple script

    I think the CPU Power Controllers could be a possibility but I would think they would fail under high load not low load. I have done those before on boards with obvious shorts on output.

    820-3662 possible fix? Simple script

    Had a 820-3662 come in for random shut down. No liquid. Checked all the rtc stuff and caps normally checked. Seems fine. Found a script online claiming the shut downs are caused by a lower power state bug in the CPU that causes failure when the CPU enters a lower power state. Before running...
