Shut down your Mac. Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4. Turn on the computer. Press and hold the Command-Option-P-R keys before the gray screen appears. Hold the keys down until the computer restarts and you hear the startup sound for the.
Recently, I was given an old Mac g4 15' Powerbook that the owner no longer wanted. This is the first Mac I have owned as well as the first laptop. It worked fine for me for several weeks, and I got a new battery and upgraded the RAM. Then it started putting itself to sleep seemingly randomly, while I was in the middle of using it.

I use it only to play online poker, since Ray has a poker client only for Windows, and it does not work well with Wine. There is a browser-based.

SleepTight provides a simple way to lock your machine when it goes to sleep or lock from a keyboard hotkey.
Sleep Tight (itch) Mac Os X
Surprisingly, Mac OS X 10.2's built in screensaver does not start automatically when the machine goes to sleep. Since the screensaver is the only Apple-supplied method of locking your machine without logging out, this means that a machine which has been put to sleep may wake up unlocked if the screensaver did not start on its own before the sleep timeout. This is especially frustrating for PowerBook users, who typically put their machines to sleep by closing the lid. Since the lid closure doesn't start the screensaver, the PowerBook will awaken unlocked. Apple has fixed this in Mac OS X 10.3 and later. 10.2 users can use SleepTight.
SleepTight is only as secure as the Apple screensaver it launches; see the FAQ for information on the potential security issues with the screensaver lock.
SleepTight offers several advantages over similar tools:
Screensaver is only started at sleep if its not already running (prevents the dueling screensaver flicker of death).
If possible, the screensaver is started before sleep, so that when the machine awakes the screensaver is already started (no flicker of visible desktop).
Screensaver preferences are automatically modified at sleep to enable the screensaver password prompt, even if it has been turned off in the Screen Effects system preferences.
Start the screensaver from a custom hotkey.
If you are looking for a more general tool to perform arbitrary actions at sleep I recommend Bernhard Baehr's SleepWatcher. Imposter-syndrome mac os.
NOTE: SleepTight can cause problems on certain Macintosh models with certain screensavers. Please be sure to read the FAQ below before you enable SleepTight.

System Requirements
Mac OS X 10.2 (Jaguar)
Please note that this software is only supported on Mac OS X 10.2 (Jaguar). Mac OS X 10.3 (Panther) is not supported because it already incorporates lock on sleep functionality. Panther users who want lock hotkey support should look at Menno Pieters's LockTight which brings SleepTight's lock hotkey support to Panther.
