Old laptop died 馃ゲ

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 馃ゲ馃

Thanks for the help guys

AMD reference cards - Difference between brands?

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

[SOLVED] Disable resizing clip to fit inside the project's resolution?

Currently, if I add a clip which is taller than the project resolution, kdenlive will scale it down so it's all visible and leave black bars at the side. Is there an option so any extra is just trimmed off instead?

I'm sorry if this is something obvious and I haven't spotted it, I'm a complete novice 馃槄


Edit: I think I've found what I need. The transform effect, and then "adjust to original size".

This is all I need but please let me know if there is a way to make this the default for a project 馃榿

[SOLVED] Any ideas what causes this in overhangs?

When I do an overhang test, I always have this problem at about 35掳. 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 35掳 at 0.2mm layer height. I now have it set to 30mm/s and it now looks great 馃憤 And sorry, I was wrong when I stated the overhang speed 馃槄

Laser printer lines across page 馃

Can anyone suggest what causes these lines across the page?

Is a new toner cartridge likely to fix this?

Edit: Line separation is 62.5mm

Edit 2: Thank you to everyone who replied. I've ordered a new toner cartridge and will update this if that solves the problem 馃

Final update: A new toner cartridge fixed it. It's now printing perfectly! Thank you.

Install Linux distros without grub??

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'.]

[FWD Manual] Gear selection problem

Can anyone suggest what might be wrong? I have just changed the clutch and now I am struggling to select gears even when the engine isn't running.

I don't think it's linkage related because it seems to be difficult to select gears just pulling directly on the arms that move the forks too. I don't think I've done anything that should have an effect on the inside of the gearbox, I've removed and refitted the drive shafts and changed the fluid.

Also can anyone confirm my thinking that the clutch and concentric slave cylinder shouldn't be a factor, since the problem exists when the engine isn't running?

Edit: Strangely, after leaving it overnight, gears are selecting perfectly again and I have absolutely no idea why. I didn't change anything 馃槙

I suppose that should be good news but without knowing what the problem was, I'm not very satisfied. Thank you to everyone for your help.
