    Mine goes down every three minutes -- or more frequently. It started today. Never had a problem with it before. Got worse all day. APLCARE acted like I was the first person who ever had this problem. Help!

The Random Shutdown Syndrome (RSS) is caused due to the heating of the heatsink.

When the heatsink warmed up it expends, and causes the system to trip. Apple replaced the defected parts and fixed the problem, i guess not for all macs...

Unexpected shut down


Good chances this is a thermal shutdown. if this is the case, the computer is shutting off to protect itself from permanent damage. if your OS is old enough (Snow leopard, I think) then the system logs show what caused the shutdown. it will give a number. anything other than a 0 or a 1 are bad. if I recall correctly 1, 5, 13 are thermal shutdowns. Newer OS's don't seem to show these codes. and Apple does not publish their meanings.

If you can't keep your laptop stable and on for longer period, and you're experiencing random shutdowns I'd say you're facing a motherboard problem. This failure is actually well known and hapens a lot with Toshiba and HP. You'll most probably need to repair the motherboard that suffers from the Maxim 1987 or Maxim 1532 power chip failure.
The repair process is fairly straightforward, but it isn't for the faint hearted. It requires a resolder of the tiny Maxim 1987 chip that should get your motherboard up and running again in no time. The other alternative is to go for a new motherboard, or just get a new laptop alltogether.
If however your laptop experiences random freezeups, and you notice that the DVD is slow at reading data, and especially if you experienced some random mouse and keyboard freezeups, then you'll need to repair the motherboard from a FSB chip failur, which causes these random freezeups, which is a bit easier to do but still a challenge.
Hope this helps

Screen goes black turns off


You are experiencing RSS (random shutdown syndrome). This seems to often be due to overheating but there are other factors. Read this article http://support.apple.com/kb/HT1237 and see if a firmware update is available for your laptop. This will often cure your very issue.

Shuts itself off periodically


If the period of time in question is reasonably consistent - say 45 minutes after powering up it shuts off - you could be suffering from an overheating issue inside the unit. Temprature sensors can override manual operation and shut the unit off to avoid greater damage (or even a fire) occuring. Have the TV serviced.
If you find it happens at random time intervals from cold this is less likely to be the case and it could be relative to the mains power supply going to the TV. If you suffer from 'dirty power' (power that dips and surges instead of giving a consistent voltage) this could also cause an automatic shutdown condition within the TV. This could happen at any time after the unit has been turned on. An unterruptible power supply (UPS) would help with that.

Shut down with no reason


It could be a overheating problem.Check the power supply.Or it could be a hardware problem may be the motherboard.I think you require a PC Tech to check the system completely.

Before my computer use to get really hot and then my computer use to shut down. I think there is a problem with the fan. Today when I switched it on the apple logo will come with the sound when it starts....


Hi,

there have been problems with MacBooks suddenly shutting down since the first Intel based MacBooks were made. It is called RSS. (Rapid Shut Down Syndrome). The cause of which I have learned in the following excerpt.
Since isolating the heatsink as the cause of the MacBook’s Rapid Sudden Shutdown (RSS), readers have isolated the specific part of the heatsink that is causing the problem, is actually the CPU thermometer itself. Essentially, the heatsink can expand during use, and comes into contact with the lead from the thermometer’s sensor cable. A short circuit results, and the SMC pulls the plug. Once the system cools down, the heatsink resides and the contact is broken. This also explains why sometimes you cannot immediately power the MacBook back on. The heatsink is still in contact with the metal lead.
Apple’s solution to this is to realign the location of the thermometer and cabling on the heatsink so that it does not short circuit. That is why the new heatsink is necessary. In the view of this writer, it warrants a public recall. Any user can produce easily the scenario that causes the MacBook to crash, even with pre-installed applications such as iLife.

My 2 cents,

Thanks

Fame !

Random Shutdown


Toshiba's are notorious dust collectors, try blowing back through the air vents and some clever use of the vacuum cleaner on the intakes can bring it back to life. also check the RAM for dust and dirt on the pins and clean as required. USE ANTI-STATIC Precautions!

Mac Mini G4 turns itself ON


Have you looked into System Preferences>energy saver>schedule? Maybe it's set up to start itself. I have my mother's mac set to start up and shut down automatically. Just a thought.
