Default What are basic diagnostic tests on a Windows laptop that won'tboot?

Here is the procedure I may need to follow:

If you're serious about doing that, *don't* use the
oven that you use to prepare food.

Find a used toaster oven, keep it outdoors while
attempting the repair. The stink of melted plastic or
burned materials will stay with your used toaster oven,
while the family food oven is kept safe.

In an industrial setting, the duration (hold time) and
temperatures are all strictly controlled.

As the posters note in your article above, if you heat the
entire motherboard, the electrolytic capacitors could
suffer. This is why a real re-work station uses a hood,
so the hot air only goes to the chip being repaired. If you
own a hot air gun, you can make a home made hood out of sheet
metal. For temperature monitoring, you could use a
thermocouple connected to a multimeter.
