Chosen Solution
Hi, I was carrying my MBP on a bag when it broke down and it fell down from 1m or so from the lateral corner where the hard drive is. There is a hole but everything works fine except for that it shuts down from time to time. It may stay a day without shutting down, or it may close one time and another for a week. Lately it’s worse and i just can’t use it any more. When it shuts down it seems like it had no power source ( though it happens both with battery and without ) Does any one have any idea of what to do? Thanks
Could be overheating, Or damage to HD Boot from Systems disk, run->Tools->Disk Utility->Disk First Aid, repair disk. Could be that the fall loosened or broke a thermal indicator, or the thermal paste. If this answer was helpful please remember to mark it accepted. Good Luck, N
I had an identical problem; eventually realized it only had the problem when the battery which was bloating was installed. replaced battery, problem solved.
Overheating. As Machead said, a thermal sensor is loose or damaged, or the thermal paste seal between the heat sink and various chips (most likely the processor) has been broken. A jolt will break the seal between the heatsink and the component it is drawing the heat away from and so will no longer function efficiently, allowing the component to overheat and shutdown to avoid any permanent damage. The existing thermal paste will need to be removed and reapplied.
