... numpad-on-letters mess ...Has anybody in the history of computing ever used that?
Lots of people have, but probably in 99%+ of cases it was unwittingly. Bonus points for "WHY WON'T IT ACCEPT MY PASSWORD??"Scarlet_Manuka:
I won't even buy a laptop without a numpad. I can't imagine using a desktop without one.It's actually pretty awesome.
I use numpad frequently, so :do_not_want.jpg: But hey, if it works for you, cool.

I use them sometimes because they give me arrows. For when that's useful...
My old Dell XPS laptop used to do that with some random keys on the keyboard (UJNIKMPL, IIRC) when NumLock or something was set. That was annoying/fun to watch (depending on if you were using it). Bonus points cause Windows kept resetting that key on logoff...

I thought solid state circuits will fry around 120C. What solder would melt below that temperature?
How do you think they solder them in the first place? With a soldering iron??

Repair requires the ability to re-solder a surface-mount chip, which requires specialized and expensive tools,
Hot air rework tools can be purchased for $100.

Well, if my CPU was that hot, I'd worry as well. But NVidia considers up to 105C to be safe and my GPU still works fine after 3 years, so I guess 95C are actually OK.

Ah so semiconductors are not destroyed by high temperatures, they just become unstable and wear down faster. That answers a few things in my head. :-) The term 'baking' always gave me a mental conflict.

Semiconductors and solid state parts have an exposure curve. Lower temperatures have a longer exposure time before damage starts occurring, higher temperatures take less time. Boards like you were talking about have solder paste applied, then the parts set in to place, then they are baked to flow the solder and make up the joints. Depending on the parts, etc, it may be higher temperatures for a very short time, or low temperatures for a longer period of time.

Given my performance in baking, I shouldn't be employed in that industry. I go for roasting flavours.
