Resposta para "MacBook Pro takes hours to turn on after battery drain"On all my Mac Noteboks, an I-book G4 and an Intel Macbook, there is a round ‘Button’ cell soldered in on the m,ain board which retains rudimentary start up information. I have replaced this cell on both my laptops after about 5-7 years, which seems to have solved similar problems to what you are experiencing.
Resposta para "After SSD installation HDD prox. Sensor is at 249°C; Fans running high"When I replaced the HDD on my I-Mac, Intel Core i3 running at 3.06 Ghz, there was a small molex type connector on the main board, right near the hard drive, which in my teardown instructions was labelled as 'Internal Temperature Sensor'. They had cautioned me, in the instructions, on removing this connector to gain access to the HDD as the solder connection on the main PCB could crack during removal. Check the solidity of this connector because, if it is broken, it will give a false signal to the Fan Controller circuit. If it has to be re soldered, you have to gain access to the bottom of the board. There is also a utility that you can download, called SMC FanControl, which allows you to set the cooling fan ON and Off temperature in the i-Mac. I used this utility to maintain my internal temperature to no mare than 120 Degrees Fahrenheit, as the iMac would start to get 'Flaky' at about 140 degrees. Update: Well, as I had used the same instructions when I took apart my i-Mac, I don't remember seeing or...
Resposta para "Why does my iMac suddenly restart?"I have seen a few of these where the problem was the Power Supply. Look on the 'Apple' site with the serial number of your power supply and then try to swap it out with a rebuilt unit. You can also check the outputs for their proper voltages, all listed on the apple site under 'troubleshooting'. There was a problem reported with a couple of components, that as soon as they heated up, they would short out and the PSU would shut down as a result. According to your display of error messages, this could also be a 'wanky' memory chip that is very voltage sensitive. I would get a good D.M.M. and check the PSU first! Good Luck.
