Q: How use Powerbook G4 as DVD player without it getting hot?
Suggestions please. Began to use older PowerBook G4 as a portable 15" DVD player. The bottom became almost hot to the touch so I hesitate
to continue watching DVDs until I know why so much heat is being generated. Might it have one of the older batteries that should be replaced?
Thank you very much. VG
PowerBook, Mac OS X (10.4.11), Use only as DVD player

Playing any video regardless of source is one of the most processor-intensive tasks you can throw at a computer. The demands on the CPU and the graphics processor are high. I'm reasonable sure the heating you see is normal.
The case bottom is part of the heat dissipation system and is designed to get hot so air moving under the case takes away the heat. Apple recommends not using their notebook models in your lap without a lapboard because that blocks one of the main cooling systems.
Are you using an external monitor with the Powerbook's lid closed (clamshell more)? If so, don't close the lid on the PowerBook; heat also escapes from the keyboard area
Notebooks in general run hot due to limited space inside that restricts the size fans that can be used. It's important to know that what "feels" hot is not necessarily dangerous to he computer. You need to get a temp monitoring utility to see actual numbers. Most notebooks will do a safety shutdown if the internal temps approach 100°C/212°F.
I like this free temp monitor:
