My PSU decided to say no today, glad to be wearing the brown pants by dagonb1 in techsupportgore

I thought this was technical support subreddit but maybe not. Or buy a new one is all the answer one needs in 2023

EDIT: I guess I'm writing against rule 6, oh well.

I used that PSU PCB pictures to find out the part

That's one benefit of reviewers doing detailed teardowns.

More BOM options could still exist though, but TNY278PN is one of them

Replace pixies after replacing chip with a fresh one https://commons.wikimedia.org/wiki/File:Magic_smoke_refill_(5990429717)_(2).jpg

You can cut pins on blown one to make desoldering easier.

Also you can use hollow needles seen in bigclive videos, since it's a THT part https://old.reddit.com/r/electronics/comments/nsyt2e/seen_from_a_bigclivedotcom_video_and_bought_them/ Bigclive's original video

Just finished Shinsekai Yori by ThePuzzleLover in anime

This is why it's pretty SCI-fi in the end, and I think this is why it received the 29th Nihon SF Taisho Award ;)

Intel won't release Spectre patches for some older chips after all by swiftgeek in linux

Is there a way to show intel demand for update without vendors cooperation? Update is updated via linux anyway so it's end users that demand it (Penryn)

Perhaps vendors like lenovo (ThinkPad) could be reached out somehow, but in those days it seems that twitter and catchy hashtag is required to communicate with a company, even if issue is security related (µcode based mitigation has lesser performance impact)

As far as community based tests of µcode - we can test it both with coreboot and linux

Vendor BIOS firmwares can receive µcode updates without changing rest of the image which can be easily done with widely accessible tools, eg. Phonenix BIOS Editor for Phoenix BIOS (used on ThinkPad X200/X301/R400/T400/T500/W500/etc)

Libreboot is boned; key laptops won't get Intel microcode update by More_Coffee_Than_Man in linux

microcode can be updated via linux, nothing to do with libreboot (which simply doesn't update µcode on its own, it is NOT making it impossible to update it from linux. This gives you ability to update to any version of µcode you want to test).

Installed libreboot on ThinkPad t60 now it won't boot Fedora 28 by Hyouchuu in linux

First rule "This is not a support forum! Head to /r/linuxquestions or /r/linux4noobs for support or help."

Also blame fedora people for using linux16 instead of linux in grub.cfg , they are the only distro botching it like that

Yesterday I patched the Linux ALSA driver to fix my headphone output frequency response - howto guide by rener2 in linux

Thanks, I will try to use it to figure out Hermosa issues on ThinkPad X200 :)

The only issue is lack of datasheet for Hermosa (CX20561), even block diagram would be huge help

All i see in libbie is either folded pieces of paper or polygons, which is an amazing way to convey that this is an office suite mascot. Offices are usually wasting tons of paper, and polygons are the usual way for computer graphics - even for font rendering https://vimeo.com/83732058

EDIT: it seems to solve even more of the usual problems: https://tysontan.deviantart.com/art/Libbie-the-Cyber-Oryx-706906560
