I found the fuse, but it wasn't blown ๐Ÿฅฒ I've looked over the board, and watched some repair videos but I haven't found anything. I've called it dead now.

Nope, no signs of life with the battery removed and on wall power only. I believe the battery was not to blame, but something went wrong that caused it to also drain the battery. I will check the battery anyway and report back if I find anything interesting. Thanks for the helpful link.

Ah, I realise my wording was very confusing there. I meant: Because the inductor is NOT the problem - I don't have any idea what the problem is - therefore the LAPTOP is dead (not the inductor)๐Ÿ˜‚

That's a great tip, but unfortunately the power supply is not turning off. I will refer to this next time though ๐Ÿ‘Œ

Current passes through it unfortunately, maybe it's possible there is a short between coils though. The inductor doesn't get hot or anything when plugged in.

  • I think I've managed to check the battery voltage, and it seems completely dead (mV).
  • I can measure 20v on the PCB whe n plugged in.
  • No fan, no LEDs, etc with either power source. There might be the slightest electrical squeek from somewhere, I will try and find out what ...

Even if I don't manage to fix it. Thanks for the suggestions ๐Ÿ‘

Great advice, but unfortunately I've checked. 20V from the supply (measured on the laptop PCB), everything removed except the ram because I only have one compatible stick - I did swap the slot though.

Just the continuity test ๐Ÿ˜…

Thanks. I guess I was just hoping it would be an easy find and fix. The beep confirmed hope is lost ๐Ÿฅฒ

I tried to start my laptop earlier, only for nothing to happen. It won't start on battery or when plugged in (it can run without a battery when plugged in). The battery does seem to be dead, and so is the 3V CMOS battery.

I opened it up and noticed a circle visable on one of the inductors. Hopefully you can see it in the picture.

Could this be the problem, or is that normal?

Update: I've tested some suggestion and watched some repair videos, but I found nothing. Goodbye old friend ๐Ÿฅฒ๐Ÿคš

Thanks for the help guys

I've never visited the site before so I just assumed it was just malicious, but as @zdanger said, it might be a hijacked legit site.

I do use uBlock. It also didn't 'feel' like an ad. I now expect the site was compromised as you suggested.

Thanks for that. I also didn't know about that shortcut until now. It will be very helpful ๐Ÿ‘๐Ÿ˜

I can't actually make it copy ๐Ÿ˜… I've now also tried in Firefox and Chrome but it still hasn't worked.

Thanks, that's very interesting to know. I assumed it was just a malicious site before.

I just saw this and felt I should share it. I'm sure most people here wouldn't fall for it but it can't hurt to make sure ๐Ÿ‘

Edit: I just wanted to add, I have no idea what this tried to copy. I'm using Firefox on Linux which is perhaps why it didn't make it to my clipboard ๐Ÿคท

AMD reference cards - Difference between brands? (lemmy.world)
 

I'm looking at buying a used reference RX 6800.

I notice there are quite a few brands for the reference model (ASUS, MSI, Sapphire, etc) and wondered if any of them use better components for example. I would quite like lower odds of having coil whine if it's related.

Just to explain my choice of card:

  • Max 40mm thick
  • Supported by Ollama
  • No proprietary software when using linux

The Mozilla layoffs ... will get worse (lemmy.world)
 

I just saw a post complaining about the Mozilla layoffs.

I wanted to point out that the vast majority of their income (over 85% in 2022) is from having Google as the default search engine - Ironically, the anti monopoly lawsuit against Google will end this.

Expect things to get worse.

Please don't assume it was just a cruel choice.

[SOLVED] Any ideas what causes this in overhangs? (lemmy.world)
submitted 1 year ago* (last edited 1 year ago) by UnH1ng3d@lemmy.world to c/3dprinting@lemmy.world

When I do an overhang test, I always have this problem at about 35ยฐ. Does anyone have a suggestion what could be causing it?

  • Slicer: Orca
  • Layer height: 0.2mm
  • Infill: 0% (this has improved it a lot, I think the infill was causing bulging)
  • Outer walls: 2
  • Overhang speed: 10 or 20mm/s (both look the same)

Solution: I mistakenly thought overhang speed in Orca was based on overhang angle, it is percentage instead (which makes much more sense for different layer heights). My 10-25% overhang speed wasn't set to slow down and that must translate to about 35ยฐ at 0.2mm layer height. I now have it set to 30mm/s and it now looks great ๐Ÿ‘ And sorry, I was wrong when I stated the overhang speed ๐Ÿ˜…

Install Linux distros without grub?? (lemmy.world)
 

I use rEFInd as my boot manager and sometimes I like to dual boot a new linux distro (just to try out) which I install with a live USB. Unfortunately, after installing, GRUB has always taken the reigns and it becomes a slight inconvenience to get back to rEFInd every time.

Is there some trick that can request grub not to install?

[What prompted me to ask was I tried KaOS yesterday, and during installation it asked what bootloader i wanted and included the option for 'none'.]
