My iBook recently enjoys randomly turning off while sleeping. Any suggestions on what could be happening? I can't afford a new one

Welcome!

Try reseting the PMU.

"The Power Manager is an integrated circuit (computer chip) that is usually on the logic board of the PowerBook and iBook. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.
Over time, the settings in the Power Manager may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not seeing the AC Adapter, among others."

When all else fails, try everything!
The Rep System and you.

It could also be the battery on the way out or out of calibration. The computer may think that there is more power left in it than there really is. I had a similar problem with a PC laptop and fixed it by re-calibrating the battery. The problem came back after another 3-4 months but was fixed with a new battery.

Experienced computer user, applications programmer and component level service engineer but came to the Apple platform with intro of intel!. Pro-photographer and director of electronics company.
