Hardware, Embedded Systems Last month, I explained why I use generic desktops and laptops running open source software. They're reliable and inexpensive. But this presumes you can fix them. I believe that even those with no hardware training (like me), can identify and fix most hardware problems. To prove it, here's a quick guide. Feel free to add whatever I've missed.

That sounds exactly like the urban legend that has been circulating around for atleast ten years now, and therefore I'm gonna call bullshit on that.


Bullshit or not - I may try this on an old laptop board I have that seems to have a cold solder joint issue.

It only turns on and stays on when I push down the front left wrist rest - and I've taken it down to the bones and reassembled it with no luck. I've concluded there's a short somewhere on the mainboard that twisting the case ever so slightly "repairs".

umccullough,

Hmm, that's odd. Ideally you could run it when the case is off and identify exactly which component is causing the problem. But with laptops this could be a challenge.

I've soldered a new power connector into a laptop where it had been damaged, but I'm not sure I'd ever feel compelled to stick one in the oven. ;)

Yeah, I tried to narrow down the location of the short while I had much of the machine apart, but with a laptop, it definitely gets tricky as you start pulling stuff apart to actually use it.

It's an old pentium 4 laptop anyway, so it's no huge loss, although it has a 1600x1200 screen which is what made it so compelling to utilize.
