IT HURTS LIKE A B!TCH!! Anyone with heart problems may want to re-evaluate thier decision to work on an undischarged unit. What does it feel like? I can only speak for the 240vac version, and have this to say about it. i.e it exists transiently until the caps discharge. if its th USA model, that slim chance is even slimmer, as the USA uses a girly 120vac as oppose to our manly 240vac in the UK.
as yet there have been NO recorded occurences.
Tried to find a schematic, or guide online, nothing much, just how to remove the whole PSU.ġ: The likelyhood of the belt delivered by the smoothing caps in one of these being fatal. Tried to get a log but before I could it shut off again.
Got it to start up from the 10.11 Mac OS disk once successfully worked fine for a couple of minutes. Tried to start up from other disks with older OS I had lying around. Tried RAM and GPU in different slots and combinations. At first not rightaway but now it just quits after a few minutes while being stuck on the progress bar in the startup screen. I have a bootscreen if I press Alt at startup. After a forced restart (after 20 minutes) the old problem returns: the machine shuts off, then sits there in with all fans blazing (with power to all components). Machine starts up, finds harddrive quicky, then hangs at 3/4 the progress bar. Not flush with cash either after investing in video equipment and lenses.įinally recieved the 3mm long hex key and paste in the mail last saturday.Ĭleaned up the inside, applied new paste for all the chips with cooling (CPU, North Bridge, one other chip). I really want to save this old beast, it's been a loyal workhorse. here's my question: Could the CPU be overheating without it registering on the temperature meter? (I'm using Mac Fan Control, it's pretty reliable, but I have no idea if the sensor is measuring the cooling element or the cpu itself)Ĭould it be the cooling paste that dried up, and the chip overheating? Sorry no screenshots, I'm typing this on my laptop. The top CPU doesn't get very warm, only 34 degrees. previously it would just boot up fine and then work for another month.Ĭould be the CPUs, Northbridge chip or PSU It does that under reasonable cpu load, then starts blowing with all fans at maximum. My old machine started switching itself off randomly.Īt first it was once every few weeks, now it's every 20 minutes.
