Crazy question - Do solid state electronics need time to warm up...

[Brian Bowers]

...before reaching peak performance? I've noticed many times that computers that have been asleep for many hours, sometimes take time to wake up.

What does "take time to wake up" mean to you?

Solid state electronics do take time to come out of sleep mode, but typically that time is a few microseconds. Desktop computers are a bit of a different story because the operating system has to perform a number of checks when coming out of sleep, but that isn't directly related to the silicon.

Data is written from the RAM to the disk while entering the sleep mode and that data is rewritten upon wakening.

Short answer-yes some do. For example, a transmitter has capacitors and coils that can slightly change values when cold-especially if the rig is properly tuned up at room temperature. Same thing is true about some solid state power devices.

There is a throwback to the old days of valve technology - where there was a significant 'warm-up' period for the heaters to reach full emission.
This doesn't apply of course to solid-state equipment, but there are a number of devices that still require a period of time to reach 'nominal' perfomance levels.
As mentioned above, computers do take some time to come out of standby or hibernate mode - especially if the hard drive has spun down.
Anything that has a crystal oven will require time to heat up to optimum temperature.
Audio amplifiers don't need time to heat up as such, but if you want to set things like quiescent output current the amplifier needs to be operating at the correct ambient temperature. At a lower temperature, the readings will be different.

Some certainly do.
I have a Transmitter that absolutely hates being cold.
So it typically sounds like crap for a half-hour upon power up, until its fully warmed up. Despite it being completely solid state. (I guess it would be the coils)

Capacitors dry out with age creating power supply issues which lengthen turn on. My old Bearcat scanner takes a long time to warm up because the big caps in the power supply need replacing. (Easier to leave on now than to replace the bad caps, until it dies for good.)
