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 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

How do you like to transfer large files between friends across the internet? in c/selfhosted@lemmy.world

I was trying to send from a wormhole app, which I now see doesn't work with the website.

Ahh, I see. I've got a wormhole app on my phone which I was trying to use to send from. I guess it just can't work with that website. Thanks

I use wormhole, but when I've wanted to use that website for receiving, I can never tell how to do it.

Can you actually use that site to receive files?

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.

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'.]
