Why doesn't my computer work until it's warm?

Episode 1288 (1:20:24)

Jerry from Alexandria, VA

A friend gave Jerry an old laptop that doesn't work very well until it warms up and he wonders if the power supply may be dead. Leo says it's possible. It's also possible that some of the solders on the motherboard really don't work well until the computer heats up and it seats the solder connections better. That was very common in the early years.
