Q: MBP 17-in ramdom shutdown. GPU heatsink 30-128 degree Celsius
Hi All
I have a very old great condition Macbook Pro 17-inch (MacbookPro2,1 2.33GHz) which was not used for about 3-4 years because of bad LCD. It was in a drawer, hidden for long time.
I recently fixed the LCD and it works fine except a problem "Random Shutdown"
For checking overheating problem or not, I installed iStat Menu program to see different temperatures and found GPU heatsink temp is 128 degree Celcius
(Approx 262 degree F). I observed that sometimes it comes down from 128 -> 40 -> 30 -> 1 and then shoots up to 128 back making flu 6000 RPM on the Fan
If my FAN is max from beginning, the Random shutdowns are much less.
I recently upgraded memory to 4GB and ran memtest program for testing. It was a very heavy load testing, and the MBP was perfectly fine.
Another problem is, when the MBP is shutdown normally/random , next power-on does not happen with or without main power plugged in … if I press power button for 5 seconds , then it starts without any problems.
Is this normal ? what could be the reason? Check the pics
