I have a new to me Toshiba 2505cds laptop.It is a P233 with 32 megs of ram internal cd and floppy drive.I have a intermitent problem that after the computer has been off for 8hrs or more the computer will not power up it starts boot leds registers and then shuts down this will happen from anywhere from 5 minutes to a 1/2 hour. It will then start and function properly.I can then restart shutdown and start shut it down for several hours and it will start flawlessly.Does this sound like a power-supply problem or motherboard glitch.
